Gold Coast-based developer <a href="https://www.apartments.com.au/developers/ignite-projects">Ignite Projects</a> has lodged a Development Application for a landmark $120 million precinct set to transform the southern gateway of the much-loved Spit.

Positioned at the most prominent entry point to the iconic peninsula, the project has been designed with a strong focus on architecture, public space, heritage and connectivity, delivering a revitalised parkland setting that invites locals and visitors to engage with the Broadwater.

Central to The Isles proposal is a significantly upgraded public realm, including landscaped open space, a new waterfront café, and a family-friendly park featuring a naval-themed playground, open lawns and improved pedestrian connections.

The design retains and celebrates key elements of the site’s history. The training mast from the vacant and degraded naval cadet building, which forms part of a former Navy minesweeper, will be preserved. The existing Navy Memorial will be relocated and upgraded in collaboration with the RSL, allowing it to be publicly accessible for the first time in years. 
&nbsp; 
Heritage-listed Humphreys Boat Shed remnants will remain and be incorporated into the landscape, while the site’s established Norfolk Pines will be retained, reinforcing the area’s character and sense of place. The enhanced parkland will ultimately create a long-term community asset at the entry to The Spit. 
&nbsp; 
The Development Application (DA) lodged with Gold Coast City Council includes 28 waterfront apartments across three levels, ranging in size from 145sqm to 383sqm, designed as a feature landmark within the precinct and complement the public domain.

&nbsp; 
Ignite Projects Director Josh Foote said the project as a whole had been carefully shaped to deliver a meaningful outcome for the wider community, not just future residents. 
&nbsp; 
“This is about more than delivering opulent apartments – it’s about creating a welcoming and memorable gateway to The Spit that people can enjoy every day,” Mr Foote said. 
&nbsp; 
“We’ve worked hard to ensure the public realm is a central part of the project, from the landscaped parklands and family-friendly spaces through to the preservation and celebration of important local heritage.”

&nbsp; 
Designed by <a href="https://www.apartments.com.au/architects/contreras-earl-architecture">Contreras Earl Architecture</a>, The Isles adopts a considered subtropical approach, with the building form shaped to maximise natural light, cross ventilation and views to the Broadwater and surrounding parklands. 
&nbsp; 
Architect Rafael Contreras said the design responded directly to its unique coastal setting. 
&nbsp; 
“Rather than a typical built form, the architecture has been shaped by performance and experience – from optimising outlook and privacy to creating a strong connection to landscape and climate,” Mr Contreras said. 
&nbsp; 
“A central landscaped courtyard allows light, air and greenery to permeate the building, while the articulated façade introduces movement and rhythm inspired by the Broadwater.

“The Isles will create a place where people can gather, relax and connect with the water, while also delivering a refined residential product that responds to its unique setting.”

&nbsp; 
The DA relates to the residential and public realm components, with a proposed boutique marina to be progressed as part of a future stage, subject to separate approvals. 
&nbsp; 
The Isles is being delivered under The Spit Master Plan, a collaborative vision to create a new residential, tourism, leisure, natural environment and cultural heritage hub on the iconic and much-loved peninsula.&nbsp; 
&nbsp; 
Ignite Projects has an established track record delivering premium residential projects across the Gold Coast, including The Monaco at Main Beach and Cabana at Palm Beach. 
&nbsp; 
Sales for The Isles are expected to commence in coming months from an on-site display suite, with construction targeted to begin later this year, subject to approvals.

Ignite Projects unveils exciting details of landmark gateway precinct for the Spit

The Federal Government’s sweeping changes to negative gearing and capital gains tax could trigger an unintended consequence: a surge of investor demand into the new and off the plan apartment sector.

While Treasurer Jim Chalmers has framed the reforms as a way to improve housing affordability and rebalance the tax system, the carve-outs for newly built housing are already positioning off the plan apartments as one of the few remaining tax-effective property investment plays.

Under the changes handed down in the Federal Budget, investors purchasing established properties after budget night will no longer be able to access negative gearing benefits. The Government will also replace the long-standing 50 per cent capital gains tax discount with a new inflation-indexation model and introduce a minimum 30 per cent tax on gains from July 2027.

However, there is a major exemption.

Investors buying new builds, including off the plan apartments, will still be eligible for negative gearing and will be able to choose between retaining the current 50 per cent CGT discount or adopting the new indexed model.

That distinction is expected to reshape investor behaviour almost immediately.

For years, established housing has dominated investor purchases because of its perceived lower risk, immediate rental returns and stronger historical capital growth. But with the tax advantages now heavily skewed toward new housing supply, the economics are changing rapidly.

The Federal Government has been explicit about its intent.

“The housing market and tax system are broken,” Chalmers said ahead of the Budget, arguing that existing concessions were disproportionately rewarding speculation rather than supporting housing supply.

The Government says the reforms are designed to encourage investment into new housing rather than established stock, a move aimed at increasing supply during a prolonged housing shortage.

According to the official Budget papers, limiting negative gearing to newly built homes is intended to “better align tax incentives with housing supply objectives.”

For the apartment development sector, particularly the off the plan market, the changes could become one of the strongest investor tailwinds in years.

Developers across Sydney, Melbourne and Brisbane have spent the past two years battling elevated construction costs, higher interest rates and subdued investor confidence. Many projects have struggled to secure sufficient pre-sales to commence construction, particularly in markets heavily reliant on investor demand.

The Budget changes may now alter that equation.

Investors seeking tax-effective property exposure will increasingly find themselves funnelled toward newly built apartments simply because established dwellings no longer offer the same benefits.

Commonwealth Bank described the reforms as one of the most significant shifts to residential property investment settings in decades, noting that the package is centred around “limiting negative gearing for residential property to new builds” while replacing the existing CGT framework.

That could have profound implications for the apartment sector.

Off the plan apartments already hold several advantages for investors. Purchasers typically secure a property at today’s price while settlement occurs years later, allowing time for capital growth and reducing the upfront capital burden. Brand-new apartments also generally attract depreciation benefits, lower maintenance costs, and stronger appeal to renters seeking modern amenity.

Now, they may also become one of the only residential property types still offering the full suite of historical tax advantages.

Industry analysts expect investor demand to increasingly migrate toward projects that can clearly demonstrate strong rental demand, transport connectivity and long-term supply constraints.

The shift is likely to be particularly pronounced in apartment markets already underpinned by structural undersupply, including inner Brisbane, the Gold Coast, parts of Sydney’s Lower North Shore and select Melbourne precincts where new apartment commencements have collapsed over recent years.

The reforms also arrive at a time when apartment supply nationally remains critically constrained.

Australia is already struggling to meet the Federal Government’s target of delivering 1.2 million new homes over five years. Construction feasibility pressures have delayed or shelved thousands of apartments across the country, particularly as building costs remain elevated and financing conditions remain tight.

Critics of the Budget changes argue the reforms could reduce overall investor participation in the housing market and place upward pressure on rents by discouraging investment in established housing.

Some economists estimate the measures could reduce housing supply over the longer term if overall investor appetite weakens.

However, the Government is betting that redirecting investor capital into new housing supply will offset those concerns.

“To continue to incentivise construction of new housing, investors building new residential properties will be able to choose either the 50 per cent CGT discount or the new arrangements,” the Budget papers stated.

That wording has been closely watched by the development industry because it effectively positions new apartments as the preferred investment class within residential property.

For off the plan developers, the reforms could become a powerful sales tool.

Projects that have increasingly relied on owner-occupier demand may once again attract investors seeking to preserve the tax advantages still attached to newly built housing before the July 2027 changes take effect.

The reforms are also expected to sharpen the divide between established and new housing markets.

Rather than a broad investor retreat from property altogether, many analysts expect a redistribution of capital toward sectors still supported by Government incentives.

That could create stronger demand for apartment projects in key urban growth corridors and transit-oriented precincts where population growth, migration and rental shortages remain elevated.

The policy direction also aligns with the Government’s broader push toward increasing housing density in established urban areas.

Across Sydney, Brisbane and Melbourne, planning reforms are increasingly encouraging higher-density apartment development around transport infrastructure and activity centres. By maintaining tax incentives for new housing, the Federal Government is effectively reinforcing that agenda from a taxation perspective.

For apartment developers who have spent years navigating subdued investor confidence, the changes may ultimately become the catalyst that reactivates parts of the off the plan market.

While the broader property sector is still digesting the long-term implications of the Budget, one thing is already becoming clear.

The era of investors buying established apartments and houses primarily for tax advantages may be ending.

But for off the plan apartments, the investment story may just be beginning.

Investors to flood off the plan apartment market?

Adding to Chatswood’s growing skyline, <a href="https://www.apartments.com.au/new-apartments/the-anderson-chatswood-54-56-anderson-street-chatswood-nsw-2067">The Anderson</a> is grounded in a simple principle: apartment living in a major centre does not have to come at the expense of space and outlook.

Set on Anderson Street in the heart of <a href="https://www.apartments.com.au/developments/chatswood-nsw-2067">Chatswood</a>, the new residential tower, a collaboration between developers <a href="https://www.apartments.com.au/developers/changfa-group">Changfa Group</a> and <a href="https://www.apartments.com.au/developers/huirong-group">Huirong Group</a> with architecture and interiors by <a href="https://www.apartments.com.au/architects/ajc-architects">AJC Architects</a>, will introduce 122 apartments that prioritise generous proportions, considered orientation, and a strong connection to the surrounding heritage precinct.

The design originated from a Design Excellence Competition, where AJC proposed a building that combines suburban-style apartment scale with the density expected in a transport-rich centre. The development will include more than 1,800 square metres of retail and commercial space at street level, landscaped communal roof terraces, and a ground-floor pocket park framed by canopy trees. Together these elements aim to create a building that integrates with Chatswood’s evolving streetscape while maintaining a strong residential focus.

[smartcode_project:default project_id=151353 project_image_fid=353250]

A key driver behind the architecture was the desire to deliver family-sized apartments rarely seen in the Chatswood market. The Anderson includes a mix of one to four-bedroom apartments, with around 35 per cent of the residences configured as three or four-bedroom homes. At the top of the building, two double-storey penthouses span approximately 200 square metres each, reinforcing the project’s emphasis on scale and long-term liveability for both downsizers and intergenerational households.

Orientation and outlook were central to the planning of the building. The apartments are positioned to maximise views to the north and east across Chatswood’s heritage precinct, with upper levels capturing glimpses of the Pacific Ocean. South-facing apartments gain distant views toward the Sydney CBD and Harbour Bridge, while the building’s configuration intentionally reduces western exposure at lower levels to minimise overlooking toward the nearby railway corridor.

The external design references the character of the surrounding conservation area without replicating it directly. A brick podium anchors the building to the street and introduces a series of architectural portals that draw inspiration from the nearby Chatswood Presbyterian Church. Above this base, the tower shifts to a lighter, more open expression defined by horizontal lines and carefully detailed balconies that balance privacy with outward views.

[smartcode_project:default project_id=151353 project_image_fid=353254]

Toward the top of the tower, AJC introduces a distinctive lantern-like element formed by sliding screens. These screens provide both solar shading and privacy while also creating a visual marker for the building within the Chatswood skyline. The feature reinforces the architectural intent of the project, a structure that is visually refined while still responding to the practical requirements of apartment living.

Inside the residences, interior architecture focuses on clear spatial flow and practical everyday use. Open-plan living areas connect directly to large balconies, extending the internal living spaces outward and allowing natural light to move deeper into the apartments. Kitchens are designed as central working spaces with premium appliances and carefully selected materials, positioned to serve both daily living and entertaining.

[smartcode_project:default project_id=151353 project_image_fid=353256]

Bathrooms follow a similarly restrained design language, using refined fixtures and materials to create calm, functional spaces, while wardrobe areas adopt a gallery-style layout with integrated lighting and generous storage. These elements reflect a broader design approach that prioritises clarity, functionality, and durability over decorative gestures.

Positioned just a short walk from Chatswood Interchange, residents will have direct access to rail, metro, retail, and dining. The Metro extension allows travel from Chatswood to Martin Place in approximately 11 minutes, placing the CBD within easy reach for residents while maintaining the convenience of a walkable North Shore neighbourhood.

One-bedroom apartments at The Anderson start from $1,022,000.

How AJC designed The Anderson to bring oversized apartment living to Chatswood

<a href="https://www.apartments.com.au/developers/bridgewell-development">Bridgewell Capital</a> has lodged plans for a major mixed-use apartment development in the heart of Maroubra, seeking a significant uplift in height and density controls to deliver 120 apartments and a 120-place childcare centre near Maroubra Junction.

The State Significant Development application, filed through the NSW Government’s Housing Delivery Authority pathway, covers a 3,270 sqm amalgamated site at 251-257 Maroubra Road and 133-135 Garden Street. The proposal includes a concurrent rezoning that would increase the maximum building height from 12 metres to 35.6 metres and lift the floor space ratio to 4.02:1.

Designed by <a href="https://www.apartments.com.au/architects/bka-architecture">BKA Architecture</a>, the project would replace a mechanic’s workshop and several detached homes with a 10-storey residential building above four basement levels.

The scheme comprises 120 apartments, including 27 affordable housing units to be managed by a community housing provider for 15 years, alongside 203 basement car spaces and 92 bicycle spaces. A childcare centre occupying nearly 900 sqm of floor area would sit at ground level and be capable of accommodating 120 children and 22 staff.

<img alt="First look: Bridgewell plots 120 apartments and childcare centre in Maroubra town centre" data-entity-type="file" data-entity-uuid="038a0639-f9e4-4303-8fcc-d43e73fa480f" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/Bridgewell%20pers.png?VersionId=eGBElxmNqJW.YF3JFYgHTnPgAstdyXR3" />

According to the Design Report, the project has been conceived as a “gateway proposal” that responds to Maroubra’s evolving urban character and its proximity to the town centre.

“Designed to complement the character of Maroubra’s town centre, this gateway proposal features a building scale that matches its surroundings,” the report stated.

“It integrates residential units above a ground-level childcare centre, fulfilling the strategic objectives of the Randwick City Council Masterplan.”

The apartment mix is weighted toward larger residences aimed at families and downsizers, reflecting changing demographics in the Randwick LGA and increasing demand for medium-density housing close to transport and amenity.

BKA Architecture said the proposal seeks to reinforce Maroubra Road as a civic spine while improving the pedestrian experience around the site through landscaping and upgraded public interfaces.

“The design capitalises on the following site opportunities: reinforcement of Maroubra Road as a civic spine, enhancement of pedestrian pathways and the public interface via new landscaping, and strong market demand for two and three-bedroom apartments to support families and down-sizers,” the Design Report noted.

<img alt="First look: Bridgewell plots 120 apartments and childcare centre in Maroubra town centre" data-entity-type="file" data-entity-uuid="ee509779-3c7e-4918-b03d-761c785459d0" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/Bridgewell%20site.png?VersionId=eZC4Ruyn.C7O.Qwfr1SVeP5.ds1c5.66" />

The building has been designed with setbacks and articulation intended to transition between the commercial intensity of Maroubra Junction and the surrounding lower-scale residential neighbourhoods. Communal open space is proposed on level one, while upper-level apartments would secure views towards Port Botany, Maroubra Beach and Sydney’s eastern suburbs.

The development sits around 200 metres east of the Maroubra Junction intersection of Anzac Parade and Maroubra Road, within one of Randwick’s identified strategic centres. The site is close to Pacific Square Shopping Centre, major bus routes, schools, parks and future cycling infrastructure proposed under the Maroubra Junction Masterplan.

The Maroubra proposal aligns with broader NSW Government initiatives encouraging higher-density housing near established centres and transport corridors, particularly where affordable housing is incorporated.

Bridgewell is also working on a <a href="https://www.apartments.com.au/news/qld/goldfields-sets-the-stage-as-quartet-milton-launches">new 55-unit project in Killara</a>.

National diversified developer <a href="https://www.apartments.com.au/developers/goldfields-group">Goldfields</a> has launched its latest Brisbane apartment project, <a href="https://www.apartments.com.au/new-apartments/quartet-milton-33-manning-street-milton-qld-4064">Quartet Milton</a>, marking its entry into the sought-after inner-city suburb just two kilometres from the CBD.

The circa $100 million development will rise 18 storeys and deliver 131 apartments, offering a mix of one, two-, and three-bedroom residences.

Ideally located on Manning Street, Quartet residents will be within 300 metres of Milton Station, 500 metres from the Milton Ferry Wharf, and a short walk to Milton Markets, the iconic Park Road, as well as a range of breweries and cafés.

[smartcode_project:default project_id=108736 project_image_fid=367993]

Designed by architecture firm <a href="https://www.apartments.com.au/architects/rothelowman">Rothelowman</a> and brought to life by <a href="https://www.apartments.com.au/architects/cera-stribley-architects">Cera Stribley</a>, the building features a simple, gridded façade paired with generous glazing to enhance views, maximise aspect, and capture both sunrises and sunsets from within the apartments and their generously sized balconies.

Residents will have access to a 1,000 sqm rooftop, curated to balance wellness and entertaining, in response to increasing demand for wellness-focused shared spaces.

"We've approached Quartet Milton as a complete lifestyle offering, not just apartments, but a place where the design, amenities, and location all work together in a meaningful way," says Goldfields Managing Director Lachlan Thompson.

"Buyers are looking for that sense of confidence, knowing the vision has been carefully thought through not just by us as developers, but by all our consultants appointed to bring this together, and that it will be delivered to the standard they expect."

[smartcode_project:default project_id=108736 project_image_fid=368000]

Cera Stribley Co-Founder and Managing Principal Domenic Cerantonio said the rooftop is designed to feel like a place "you'd genuinely use every day."

"A 25-metre pool framed by city and mountain views, wellness areas, and private dining spaces for evenings with friends create a setting designed for year-round comfort and effortless Brisbane living."

[smartcode_project:default project_id=108736 project_image_fid=367999]

In addition to the 25-metre pool, the rooftop will include a sauna, cold plunge, fully equipped gym, and zen gardens, all complemented by panoramic views of the city and river.

While the building is expected to appeal predominantly to owner-occupiers, Goldfields anticipates interest from investors seeking strong rental returns, driven by the project's design, location, and the city's projected capital growth in the lead-up to the 2032 Brisbane Olympics.

[smartcode_project:default project_id=108736 project_image_fid=367991]

<a href="https://www.apartments.com.au/developments/milton-qld-4064">Milton</a>, widely regarded as one of Brisbane's most desirable inner-ring suburbs due to its lifestyle offering and proximity to the CBD, has experienced a shortage of new apartment supply in recent years.

Goldfields is already active in the Brisbane residential market through its Ripley Valley masterplanned community, Hayfield. The 109-hectare neighbourhood is already home to more than 300 families and features a large community park.

Plans for the precinct include a 4 km running track, future schools, and retail and commercial amenities, all within a 35-minute drive of the Brisbane CBD.

Goldfields also plans to deliver a new mixed-use tower at 88 Robertson Street in Fortitude Valley, within the James Street precinct. The project will include 16,000 sqm of boutique commercial space, a level of wellness facilities, and a rooftop restaurant and event space, akin to Goldfields House in South Yarra, its flagship mixed-use development on Chapel Street, which is crowned by the Beverly Rooftop bar, one of Melbourne’s best-known venues.

Clean Energy

<html><body>
EXPERT OBSERVER
As climate change worsens, the future of fossil fuel jobs and infrastructure is uncertain. But a new energy storage technology invented in Australia could enable coal-fired power stations to run entirely emissions-free.
The novel material, called miscibility gap alloy (<a href="https://www.mgathermal.com/publications" target="_blank">MGA</a>), stores energy in the form of heat. MGA is housed in small blocks of blended metals, which receive energy generated by renewables such as solar and wind.
The energy can then be used as an alternative to coal to run steam turbines at coal-fired power stations, without producing emissions. Stackable like Lego, MGA blocks can be added or removed, scaling electricity generation up or down to meet demand.
MGA blocks are a fraction of the cost of a rival energy storage technology, lithium-ion batteries. Our invention has been <a href="https://link.springer.com/chapter/10.1007%2F978-3-319-69844-1_48" target="_blank">proven</a> in the <a href="https://www.sciencedirect.com/science/article/abs/pii/S0038092X19304220?via%3Dihub" target="_blank">lab</a> – now we are moving to the next phase of proving it in the real world.
<img src="https://images.theconversation.com/files/356669/original/file-20200907-114278-1w0c69l.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt="Steam billows from a coal-fired power station"> MGA blocks promise to give new life to old coal stations. Themba Hadebe/AP
<h2>Why energy storage is important</h2>
Major renewable energy sources such as solar and wind power are “intermittent”. In other words, they only produce energy when the sun is shining and the wind is blowing. Sometimes they produce more energy than is needed, and other times, less.
So moving to 100% renewable electricity requires the energy to be “dispatchable” – stored and delivered on demand. Some forms of storage, such as <a href="https://about.bnef.com/blog/behind-scenes-take-lithium-ion-battery-prices" target="_blank">lithium-ion batteries</a>, are relatively expensive and can only store energy for short periods. Others, such as hydro-electric power, can store energy for longer periods, but are site-dependent and can’t just be built anywhere.
If our electricity grid is to become emissions-free, we need an energy storage option that’s both affordable and versatile enough to be rolled out at massive scale - providing six to eight hours of dispatchable power every night.
MGAs store energy for a day to a week. This fills a “middle” time frame between batteries and hydro-power, and allows intermittent renewable energy to be dispatched when needed.
<img src="https://images.theconversation.com/files/356670/original/file-20200907-111081-1h20soe.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt="Researchers Alex Post and Erich Kisi, look at a MGA block."> Researchers Alex Post and Erich Kisi. The company is looking to built a pilot manufacturing plant in NSW. Authors provided
<h2>How our invention works</h2>
In the next <a href="https://www.energynetworks.com.au/news/energy-insider/the-demise-of-coal/#:%7E:text=Share%3A,%2Dintensive%20coal%2Dfired%20generation.&amp;text=Since%202016%2C%202.8%20GW%20of,end%20of%20its%20productive%20life" target="_blank">two decades,</a> many coal-fired power stations around the world will retire or be decommissioned, including <a href="https://www.theguardian.com/environment/2019/dec/12/almost-two-thirds-of-australias-coal-fired-generation-will-be-out-by-2040-aemo-says" target="_blank">in Australia</a>. Our proposed storage may mean power stations could be repurposed, retaining infrastructure and preventing job losses.
For coal stations to use our technology, the furnace and boiler must be removed and replaced by a storage unit containing MGA blocks.
MGA blocks are 20cm x 20cm x 16cm. They essentially comprise a blend of metals – some that melt when heated, and others that don’t. Think of a block as like a choc-chip muffin heated in a microwave. The muffin consists of a cake component, which holds everything in shape when heated, and the choc chips, which melt.
The blocks don’t just store energy – they heat water to create steam. In an old coal plant, this steam can be used to run turbines and generators to produce electricity, rather than burning coal to produce the same effect.
<iframe src="https://www.youtube.com/embed/bt-Ux48Aohw?wmode=transparent&amp;start=0" frameborder="0" width="440" height="260"></iframe> Courtesy University of Newcastle.
To create the steam, the blocks can be designed with internal tubing, through which water is pumped and boiled. Alternatively, the blocks can interact with a heat exchanger – a specially designed system to heat the water.
Old coal plants could run on renewable energy that would otherwise be switched off during periods of oversupply in the middle of the day (in the case of solar) or times of high wind (wind energy).
Our research <a href="https://www.rees-journal.org/articles/rees/full_html/2017/01/rees170037s/rees170037s" target="_blank">has shown</a> the blocks are a fraction the cost of a lithium battery of the same size, yet produce the same amount of energy.

<h2>Proving MGA blocks in the real world</h2>
Our team perfected the novel material through research at the University of Newcastle between 2010 and 2018. Last year we formed a company, MGA Thermal, and are focused on commercialising the technology and conducting real-world projects.
In July this year, MGA Thermal received a A$495,000 grant from the federal Department of Industry, Innovation and Science, to establish a pilot manufacturing plant in Newcastle, New South Wales. This project is due to start operating in the second half of next year. The goal is to begin manufacturing a commercial quantity of MGA blocks economically, at scale, for large demonstration projects.
MGA Thermal have partnered with a Swiss company, E2S Power AG, to test the technology in the rapidly changing coal-fired power industry in Europe. Beginning next year, the testing will include retrofitting a functioning coal power plant with MGA storage. This will also verify the economic case for the technology.
We are aiming for a cost of storage of A$50 per kilowatt hour, including all surrounding infrastructure. Currently, lithium-ion batteries cost <a href="https://about.bnef.com/blog/behind-scenes-take-lithium-ion-battery-prices" target="_blank">around A$200 per kilowatt hour</a>, with added costs if energy is to be exported to the electricity grid.
So what are the downfalls? Well, MGA does have a much slower response time than batteries. Batteries respond in milliseconds and are excellent at filling short spikes or dips in supply (such as from wind turbines). Meanwhile MGA storage has a response time above 15 minutes, but does have much longer storage capacity.
A combination of all three options – batteries, MGA/thermal storage and hydro – would provide large-scale energy storage that can still respond quickly to fluctuating renewable supply.

<h2>Safe and recyclable</h2>
MGA blocks are safe and non-toxic – there is no risk of explosion or leakage, unlike some other fuels.
The blocks can also be recycled. They are expected to last 25-30 years, then can be easily separated into their individual materials - to be made into new blocks, or recycled as raw materials for other uses.
Like any new technology, MGA blocks must be financially proven before they’re accepted by industry and used widely in commercial projects. The first full-scale demonstrations of the technology are on the horizon. If successful, they could allow coal-fired power plants to be used cleanly, and provide hope for the future of coal workers.<img src="https://counter.theconversation.com/content/144864/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important; text-shadow: none !important;">

Aussie invention could save old coal stations by running them on zero-emissions 'Lego' blocks

<html><body>
GUEST OBSERVATION
 
Australia’s energy market is outdated. It doesn’t encourage competition and that’s holding back the <a href="http://www.unswlawjournal.unsw.edu.au/wp-content/uploads/2017/09/39-4-6.pdf">transition</a> to renewable energy. Important reforms to modernise the market are on the way, but big energy companies are seeking to use the cover of COVID-19 to prevent the change.
This is bad for consumers, and for climate action. Reform would help create a modern grid <a href="https://www.propertyobserver.com.au/https://relp.lexxion.eu/article/RELP/2011/2/44">designed</a> around clean energy, pushing coal-fired generators to retire earlier. Over time, it would also bring down power costs for households and business.
Renewable energy is the cheapest form of new electricity. It’s far better for the environment than coal and gas, and can deliver reliable supplies when backed by batteries and other energy storage.
Instead of delaying reform, Australia should be advancing it.
What’s this all about?
Regulators and governments recognise the need to modernise the rules governing the National Electricity Market. That market, established in 1998, supplies all Australian jurisdictions except Western Australia and the Northern Territory.
Reliable electricity requires that supply and demand be kept in balance. This balance is primarily provided by a system known as the <a href="https://www.aemc.gov.au/sites/default/files/content//Five-Minute-Settlement-directions-paper-fact-sheet-FINAL.PDF">wholesale spot market</a>. Every five minutes, electricity generators bid into the spot market, specifying how much energy they will provide at a certain price.
An entire <a href="http://www.coagenergycouncil.gov.au/publications/post-2025-market-design-national-electricity-market-nem">redesign</a> of the market rules is scheduled for 2025. This should make the market work efficiently and reliably as coal retires and is replaced by renewable energy.
In the meantime, one important rule change is due to start in July next year, known as “<a href="https://www.aemc.gov.au/rule-changes/five-minute-settlement">5-minute settlement</a>”.
Currently, electricity is sold and sent out from generators in 5-minute blocks. But the actual price paid for this electricity in the wholesale market is averaged every 30 minutes. This means there are six dispatch periods, each with their own price, which are then averaged out when the market is settled.
This strange design has enabled big electricity generators to <a href="https://www-sciencedirect-com.ezp.lib.unimelb.edu.au/science/article/pii/S0140988316301839">game the market</a>. One method involves placing high bids in the first interval, then placing low or even negative bids in the remaining five intervals. This ensures that electricity from the big generators is purchased, but that they and all other generators receive an artificially high average price for the whole 30-minute period.
In 2017, the Australian Energy Market Commission (AEMC) <a href="https://www.aemc.gov.au/sites/default/files/content/97d09813-a07c-49c3-9c55-288baf8936af/ERC0201-Five-Minute-Settlement-Final-Determination.PDF">decided</a> to replace 30-minute settlement with 5-minute settlement.
<a href="https://www.aemc.gov.au/sites/default/files/content//Five-Minute-Settlement-directions-paper-fact-sheet-FINAL.PDF">The commission says</a> the current system was adopted more than 20 years ago due to technological barriers which have since been overcome. It argues moving to 5-minute settlement would better reflect the value to consumers of fast-response technologies, such as batteries storing renewable energy and so-called “demand response” (a concept we’ll explain later).
<a href="https://www.aemc.gov.au/rule-changes/five-minute-settlement">According to</a> the AEMC, the rule change would lead to lower wholesale costs, cutting electricity prices for consumers.
But on March 19 this year, the Australian Energy Council, which represents most coal-fired power stations and the big three electricity retailers, sought to delay the reform. It wrote to federal energy minister Angus Taylor and his state counterparts, arguing the pandemic means energy companies must focus on “<a href="https://www.energycouncil.com.au/analysis/covid-19-brings-reform-challenges/">critical supply and reliabilty</a>” issues, rather than implementing the rule change.
But energy consumption has <a href="https://www.tai.org.au/content/national-energy-emissions-audit-april-2020">barely changed</a> during the pandemic, the Australia Institute’s national energy emissions audit shows. So delaying the reform to deal with supply and reliability issues appears unjustified.
Despite this, the Australian Energy Market Operator has proposed delaying the change for a year. Our <a href="https://www.tai.org.au/content/delaying-energy-market-reform-increase-costs-slow-transition-renewables-think-tank-industry">submission</a>, endorsed by energy and technology leaders, opposes the delay.
Moves by regulators to delay another <a href="https://reneweconomy.com.au/regulators-flag-delays-to-16-energy-reform-projects-as-fossil-fuel-interests-dig-in-15284/">16 market reforms</a> due to COVID-19 also seem to be afoot.
Change is possible
Last week, one big rule change to the National Electricity Market did proceed as planned. <a href="https://www.propertyobserver.com.au/https://www.abc.net.au/news/2020-06-11/customers-paid-for-reducing-electricity-demand-radical-change/12343790">It allows</a> “demand response” energy trading from 2021.
<a href="http://www.tai.org.au/content/finkel%E2%80%99s-forgotten-finding-%E2%80%93-%E2%80%98negawatts%E2%80%99">Demand response</a> involves reducing energy consumption during peaks in demand, such as during heatwaves. Basically, the rule means big energy users, such as smelters and manufacturing plants, could power down in these periods, and be paid for doing so.
Technology pioneers such as battery entrepreneur <a href="https://www.afr.com/companies/energy/covid-19-may-delay-national-electricity-market-reform-20200419-p54l3s">Simon Hackett</a> and Atlassian chief <a href="https://www.smh.com.au/politics/federal/ambitious-energy-reforms-set-to-cut-household-power-bills-20200611-p551rs">Mike Cannon-Brookes</a> have backed this change.
Australia has successfully used demand response to provide <a href="https://arena.gov.au/assets/2019/03/demand-response-rert-trial-year-1-report.pdf">emergency</a> electricity capacity and <a href="https://www.afr.com/news/demand-response-worth-half-a-liddell-to-energy-queensland-20180404-h0ybij">other</a> <a href="https://www.aemc.gov.au/rule-changes/demand-response-mechanism">benefits</a>. But it’s never been unleashed in the wholesale energy market.
The rule change doesn’t involve smaller users such as households. But it’s a promising start that creates new competition for fossil fuel generators and allows energy users to help make the grid more reliable.
Political warfare over climate policy has held back Australia, <a href="https://onlinelibrary.wiley.com/doi/abs/10.1111/1467-8500.12328">and the electricity market</a>, for more than a decade. But energy reform that encourages greater market competition can readily be supported by political conservatives.
The demand-response rule change is a clear example: it has been <a href="https://www.minister.industry.gov.au/ministers/taylor/media-releases/wholesale-demand-response-help-lower-costs-and-strengthen-energy">championed by Taylor</a> and his predecessors <a href="https://www.propertyobserver.com.au/https://www.abc.net.au/news/2017-07-13/negawatts-touted-as-solution-to-growing-energy/8707232">Josh Frydenberg</a> and <a href="https://www.theaustralian.com.au/national-affairs/climate/coalition-seeks-deal-to-cut-power-demand/news-story/5b7a3dd86ddf11c91d5f817405bb43a9">Greg Hunt</a>.
Getting future-ready
Once the health crisis is over and economic recovery has begun, Australia will need the economic and social benefits of electricity market reform even more than before.
Such reform “<a href="https://www.tai.org.au/content/energy-reform-after-covid-19">stimulus</a>” would help ready the grid for the inevitable retirement of coal-fired power stations, such as Liddell in 2023.
It would also align with state government investments in renewable energy, and boost private investment in new generation (which has <a href="https://reneweconomy.com.au/cec-calls-for-action-on-grid-issues-as-renewables-investment-cut-in-half-28289/">recently slumped</a>) and <a href="https://thenewdaily.com.au/finance/finance-news/2020/05/26/coronavirus-manufacturing-industry/">large-scale batteries</a>.
Electricity remains Australia’s <a href="https://theconversation.com/australia-to-attend-climate-summit-empty-handed-despite-un-pleas-to-come-with-a-plan-123187">highest-polluting sector</a>. Around the world, electricity markets are planning the <a href="https://www.ren21.net/renewables-report-launch/">transition</a> from high to low emissions.
Delaying reform in Australia would be a major setback on the path to our essential energy transition.

Energy giants want to thwart reforms that would help renewables and lower power bills

<html><body>
A new report has found in 2015 Australia’s had the 7th highest number of solar PV systems installed in the world, equating to one solar panel per Australian resident.
The Clean Energy Australia 2015 report shows renewable energy provided 14.6 percent of Australia’s electricity in 2015 - enough to power 6.7 million homes, up on the 13.5 per cent of electricity delivered by renewables the year before despite a significant drop in hydro generation due to lower rainfall. 
<div>
<ul>
<li>Wind and solar generation rose by more than 20 percent. </li>
<li>Rooftop solar power is now at 5 gigawatts capacity which is equivalent to a power station large enough to light up all the homes in Brisbane and Perth. </li>
<li>Five new wind farms were built in 2015 as well as eight solar farms larger than 1 megawatt capacity. </li>
<li>More than 14,000 people are employed in the renewable energy industry, which is still recovering from the 5000 jobs that were lost (one in four) between 2011-12 and 2014-15.</li>
</ul>
