A full-scale Sky Homes prototype apartment for <a href="https://www.apartments.com.au/new-apartments/zeste-at-the-orchards-norwest-104-fairway-drive-norwest-nsw-2153">Zeste</a> has been opened by <a href="https://www.apartments.com.au/developers/sekisui-house-australia">Sekisui House Australia</a>, offering buyers a look at the final residential release within The Orchards masterplan in <a href="https://www.apartments.com.au/developments/norwest-nsw-2153">Norwest</a>.

The prototype launch coincides with buyer demand for larger apartment living continuing across Sydney’s Hills District.

David Lee, Sales Manager, Apartment &amp; Mixed-Use Developments at Sekisui House Australia said it was evident from the preceding four stages at The Orchards that a large number of buyers were local owner occupiers or downsizers specifically looking for oversized apartments with additional living spaces.

“The majority of buyers prefer to touch, feel and physically sight a full-scale completed apartment, rather than imagining the living spaces from floor plans," Lee says.

"The prototype apartment provides greater clarity and buyer confidence. We expect this will increase sales momentum for Zeste and the Sky Homes in particular.”

[smartcode_project:default project_id=150510 project_image_fid=351878]

Positioned within Stage 5’s Zeste project, the Sky Homes form part of the final opportunity to purchase within the award-winning master-planned community, which will ultimately deliver approximately 1,300 apartments.

Designed by <a href="https://www.apartments.com.au/architects/rothelowman">Rothelowman</a>, Zeste comprises two residential buildings, Essence and Eden, providing 209 apartments surrounded by extensive landscaping, resort-style amenities and community spaces.

Ben Pomroy, Principal at Rothelowman said Zeste explores a reinvention of the traditional house, in the orchard, synthesising the nostalgic story of the orchard homestead of yesteryear with a contemporary aesthetic inspired by the landscape.

“Natural light and ventilation are key to the design, contributing to a higher quality of life at the human scale. Across all Rothelowman projects, our ethos of ‘a generous eye for life’ drives our consideration of the human experience as the central point of focus of our design process.”

Pomroy says a&nbsp;notable design element is the cathedral glass light boxes incorporated in the joinery, inspired by the idea of wandering the orchard homestead with a lantern in hand, something familiar and nostalgic.

"We took this narrative and gave it a contemporary twist that is both beautiful and functional, creating unique features that unify the kitchen and bathrooms design.”

[smartcode_project:default project_id=150510 project_image_fid=351874]

In addition to the two residential buildings, Zeste comprises a single-story community amenity pavilion nestled in the landscape between Essence and Eden.

“The communal pavilion is a distinctive feature designed to foster a deep sense of community, with nature at its heart," Pomroy added.

"Whether it is watching the football grand final or hosting a family BBQ, the pavilion is designed as a place where residents can create memorable moments with friends, family and neighbours.

Since launching Essence, the first building within Zeste, buyer demand has remained strong with more than 30 per cent of residences already sold. Sky Homes have accounted for nearly 40 per cent of all sales achieved since launch.

“Purchasers are responding positively to the oversized layouts, diverse apartment configurations and the vast range of community facilities that will be available at completion,”David Lee noted.

Zeste Sky Homes represent approximately 35 per cent of the entire Stage 5 offering and are available across both Essence and the yet-to-launch Eden building. Prices for the Sky Homes range from $1,135,000 with one car space through to $1,500,000 for two car spaces.

Apartments across the broader Zeste release start from approximately $715,000, with generous floorplans ranging from 59 to 144sqm. Select residences also feature integrated ‘Max’ spaces, designed to function as flexible areas for home offices, children’s playrooms or additional storage.

Zeste also continues Sekisui House Australia’s sustainability partnership with Altogether Group, delivering integrated water, power and data services alongside passive design initiatives including cross-ventilation, landscaping and water features.

Early purchasers are currently able to access a selection of premium upgrade options, with VIP buyers receiving one complimentary upgrade package. A 2.5 per cent deposit is available for a short time.

Sekisui recently commenced its pre-construction phase. They are expecting an early 2028 completion of Zeste.

Zeste Sky Homes prototype opens as buyer demand surges for oversized apartment living

Having recently announced its entry into the booming Gold Coast new apartment market with <a href="https://www.apartments.com.au/new-apartments/aere-chevron-island-18-20-mawarra-street-surfers-paradise-qld-4217">Aere Chevron Island</a>, developer Martello™ is offering generous stamp duty savings for buyers before June 30.

Martello™ says the incentive creates a more accessible entry into premium apartment living.

"While incentives in property are nothing new, today’s stamp duty contributions arrive at a particularly important moment," the developer says.

"Buyers are not only seeking quality homes and strong locations; they are also looking for smarter financial entry points. Reducing or offsetting stamp duty can represent tens of thousands of dollars in savings - funds that can instead be directed toward furnishing a home, reducing mortgage pressure, or simply providing peace of mind during the transition into ownership."

[smartcode_project:default project_id=143932 project_image_fid=367517]

Aere is one of the more boutique new developments on Chevron Island, with just 33 apartments across 18 storeys on Mawarra Street

The developer has placed a strong emphasis on wellness, briefing architecture firm Raunik Design to embed this philosophy into the project.

<a href="https://www.apartments.com.au/developers/martello">Martello™</a>&nbsp;has positioned Aere as a continuation of its human-centric development approach, with a focus extending beyond amenity to the fundamentals of layout, natural light, and spatial planning.

[smartcode_project:default project_id=143932 project_image_fid=368446]

To bring a heightened level of confidence to the project, <a href="https://www.apartments.com.au/developers/martello">Martello™</a>&nbsp;has already appointed Promax Construction to build the tower. They are expected to start construction in the coming months.

Martello™ says that in any market cycle, confidence matters.

"Buyers who may have been waiting on the sidelines are now reassessing their timing as developers and vendors introduce meaningful incentives designed to support decision-making. For owner-occupiers, it creates an opportunity to secure a premium residence with reduced upfront costs. For investors, it can improve the overall acquisition equation at a time when rental demand remains exceptionally strong across many key markets."

&nbsp;

[smartcode_project:default project_id=143932 project_image_fid=367507]

Aere offers a mix of two-, three-, and four-bedroom apartments, the latter of which occupy half a flor. These layouts prioritise separation between living and sleeping zones, along with increased privacy and storage, features more commonly associated with detached housing than traditional apartment product.

Aere’s private resident amenity spaces centre on wellness. A rooftop level will incorporate a heated swimming pool, sauna and spa, alongside a residents’ lounge, dining areas and barbecue spaces, while additional shared facilities throughout the building include a gym and yoga area.

[smartcode_project:default project_id=143932 project_image_fid=367515]

&nbsp;

"What we are seeing now is a market that rewards readiness," Martello added.

"Buyers who are informed, financially prepared, and willing to act decisively are finding opportunities that may not exist once conditions shift again. Incentives such as stamp duty contributions are typically limited in duration and allocation, particularly within tightly held developments where demand remains high.

&nbsp;

Offer available on selected residences at Aere Chevron Island only. Stamp duty contribution provided by the developer at settlement and cannot be exchanged for cash or combined with any other offer unless approved by the developer. Offer valid for contracts signed on or before 30 June 2026. The developer reserves the right to amend or withdraw the offer at any time without notice. Terms and conditions apply.

Martello™ offers limited time stamp duty concessions at Aere Chevron Island

New development specialists Lachlan Cottee and Ben Dalgleish have unveiled their new development firm, Dalcott, following several successful projects delivered under the Pyco banner across the region.

Pyco is currently delivering Atelier in nearby West End, Nouveau in Albion, and Onde at Kirra, its debut Gold Coast apartment development in the booming Kirra Beach precinct.

Its first plans under the new Dalcott banner are in South Brisbane, which has been Brisbane’s most enquired-on suburb so far in 2026, while neighbouring West End has also continued to record strong demand.

The developer already has approval for an 11-storey building with 65 apartments on Browning Street, however has recently acquired the adjoining 910 sqm site at the rear, creating a combined 2,746 sqm footprint that will now allow for two 11-storey buildings with 92 large-scale apartments, a configuration Cottee and Dalgleish have focused on across their local portfolio.

The project, known as <a href="https://www.apartments.com.au/new-apartments/marrone-south-brisbane-39-browning-street-south-brisbane-qld-4101">Marrone</a>, will comprise 84 three-bedroom apartments, 16 of which will include an additional multipurpose room, and just eight two-bedroom residences.

DAH Architecture has led the design of Marrone, which will include more than 330 sqm of communal open space and rooftop recreation areas.

<img alt="Marrone" data-entity-type="file" data-entity-uuid="7eeea1a0-be23-47c8-80fb-3409428241fd" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/Screenshot%202026-05-21%20at%209.36.38%E2%80%AFAM.png?VersionId=pZW7o.tB7oJovYCRIFSxrZbMr6QdpHy." />

Cottee told Apartments.com.au the project reflects a gap in Brisbane’s apartment market.

"It is an area we know well with Atelier, another development which focuses on large apartments, less than 300 metres away," Cottee says.

"There's limited supply of large-scale apartments of this size in a single building in Brisbane. The majority of apartments in this category are in considerably smaller buildings, on the water, and are only really accessible to the deepest of pockets.

"Marrone will offer the same size and scale, but with greater amenity and at a much more realistic price point for the market."

The architectural approach reflects the continued evolution of South Brisbane’s higher-density residential character. Renders show a heavily landscaped façade composition with curved balconies, textured brickwork, deep recesses, and integrated planting aimed at softening the scale of the twin towers.

The revised proposal builds on the design narrative established in the original scheme. In the earlier submission, Gatehouse Architects described the project as a continuation of Browning Street’s long-term urban transformation.

“The proposal echoes the spirit of early developments like Watson Terrace (built in 1888), by contributing to the growth and diversification of the local population,” the original design statement noted.

“Just as Watson Terrace played a role in the area’s early gentrification, this development continues that trajectory, delivering contemporary housing that addresses the evolving needs of South Brisbane’s expanding community.”

The updated proposal, designed by DAH Architecture, spans a 2,746 sqm corner site with frontages to Browning and O’Connell Streets. The development will comprise two 11-storey residential buildings delivering 92 apartments, replacing the previously proposed 65-unit scheme.

The apartment mix has shifted further toward larger owner-occupier residences, continuing Dalcott’s established strategy across South East Queensland. The plans include 68 three-bedroom apartments, 16 three-bedroom apartments with multipurpose rooms, and eight two-bedroom residences. Two basement levels will provide 142 car spaces, alongside bicycle parking for 115 bikes.

The larger Marrone proposal arrives amid sustained redevelopment momentum across South Brisbane and the wider Kurilpa precinct, where developers are increasingly targeting owner-occupiers seeking larger apartments close to the CBD, cultural precincts, and riverfront amenity.

The site sits within walking distance of South Bank, the Queensland Performing Arts Centre, Brisbane State High School, and several major transport connections, while nearby Fish Lane and West End continue to drive demand for higher-end inner-city apartments.

Cottee is expecting Marrone to launch around August with Realm Projects.

<a href="https://www.apartments.com.au/developers/doma-group">DOMA Group</a> has unveiled plans for Newcastle Quay, a major waterfront precinct set to reshape Newcastle’s harbourfront and further cement the city’s evolution into one of Australia’s fastest-growing urban destinations.

Positioned on a prominent site within the Honeysuckle Precinct, Newcastle Quay will span both sides of Honeysuckle Drive, connecting directly to the Foreshore Promenade and sitting within walking distance of Newcastle Interchange.

The mixed-use precinct is planned to include around 1,000 apartments, more than 28,000 sqm of commercial office space, 6,000 sqm of retail, and a 180-room hotel anchored by a 500-seat conference and exhibition centre, a move expected to significantly lift Newcastle’s ability to attract major business and tourism events.
</section>

<img alt="DOMA Group unveil Newcastle’s future with transformative Newcastle Quay Precinct" data-entity-type="file" data-entity-uuid="0642ca09-67cc-4920-8a7e-d18df9729b4e" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/%3D.png?VersionId=CnDmZxQnOV5LN0ePu7jaFBXC9tPGTrWm" />

The proposal builds on DOMA’s growing Newcastle pipeline, where the developer has already delivered 866 apartments and more than 19,000 sqm of commercial and retail space since entering the market in 2013. A further $2 billion pipeline is also in the works across the city.

The masterplan and executive architecture are led by <a href="https://www.apartments.com.au/architects/sjb-architects">SJB</a>, with building concepts developed alongside Stewart Architecture, Architecture AND and Curious Practice, and landscape design by <a href="https://www.apartments.com.au/landscape-architect/turf-design">Turf Design Studio</a>. More than 11,000 sqm of open space is planned, including a new waterfront park known as Honeysuckle Green, upgrades to Tree of Knowledge Park, and new pedestrian and cycling links throughout the precinct.

At the centre of the development will be the heritage-listed Wickham School of Arts, which DOMA plans to reposition as the civic and cultural heart of the precinct through restaurants, bars, events and public gathering spaces.

The broader vision is to create a genuine day-to-night precinct, blending residential, hospitality, retail, commercial and cultural uses in a way Newcastle has yet to experience at this scale.

DOMA Group Managing Director Jure Domazet said the aim was to create a precinct that becomes synonymous with Newcastle itself.

“Our vision is to create a precinct that not only delivers high-quality commercial, residential, and cultural spaces, but also defines Newcastle’s waterfront for generations to come,” Domazet said.

DOMA’s Chris Farrington said the project would fundamentally change how Newcastle is perceived nationally.

“Newcastle Quay is more than a waterfront precinct, it is a national announcement for this city,” Farrington said.

“A world-class Conference and Exhibition Centre will open Newcastle and the Hunter Region to a national and international audience for the first time, delivering something this city has long deserved.”

The project is expected to generate more than 4,000 full-time equivalent jobs and act as a major economic driver for the Hunter region through tourism, business events, hospitality and commercial investment.

&nbsp;

&nbsp;

Minister for Planning and Public Spaces Paul Scully said the final parcel of harbourfront land will be a "true mixed-use precinct destination that includes housing, hospitality and entertainment, commercial spaces, retail, economic and social outcomes."

DOMA Group unveils 1,000-apartment Newcastle Quay precinct

ASX-listed developer Stockland is continuing to ramp up its return to the apartment market.

In late 2024, <a href="https://www.apartments.com.au/developers/stockland">Stockland</a> announced it would resume apartment development after a 13-year absence, launching with Stanton Place in Rosebery, a 144-apartment project now under construction.

Last week, the developer unveiled plans alongside the NSW Government for a <a href="https://www.apartments.com.au/news/nsw/first-look-stockland-nsw-gov-unveils-plans-for-3-300-home-waterloo-south-renewal">3,300-home precinct in Waterloo</a>.

Now, Stockland has shifted its focus in St Leonards, lodging a State Significant Development Application (SSDA) to replace an approved 42-storey office tower with a 52-storey residential development comprising more than 500 apartments.

<img alt="Stockland" data-entity-type="file" data-entity-uuid="8979095e-9072-432b-a7da-58b180cf994d" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/Screenshot%202026-05-20%20at%204.27.36%E2%80%AFPM.png?VersionId=_jbRXYOafCSHjwsz.yQCNIymMyCj8zkF" />

An existing 14-storey commercial office building would make way for a 264.5-metre tower designed by <a href="https://www.apartments.com.au/architects/bates-smart">Bates Smart</a>. The project would deliver 538 apartments, including 30 affordable housing units, alongside retail and commercial uses at the podium and ground plane.

It will rise from&nbsp;<a href="https://www.apartments.com.au/new-apartments/601-pacific-highway-st-leonards-nsw-2065">601 Pacific Highway</a>, a prominent 2,844 sqm triangular site adjoining Mitchell Plaza and fronting Pacific Highway.

The development is being pursued under the Housing Delivery Authority pathway after Stockland’s proposal was declared State Significant Development earlier this year.

<img alt="First look: Stockland plans 52-storey mixed-use tower with 538 apartments in St Leonards" data-entity-type="file" data-entity-uuid="67f40f35-0458-47ab-80c0-a4e98a31838a" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/stockland%201.png?VersionId=rxXe3njr.auuGDuiR0k42uI8Zr4K.gZA" />

The apartment mix includes 217 one-bedroom apartments, 191 two-bedroom apartments, 122 three-bedroom apartments, and eight four-bedroom residences. Six basement levels would accommodate 300 car spaces, bicycle parking, loading areas, and building services.

Bates Smart said the project has been shaped around a series of urban design principles intended to improve the pedestrian experience and respond to the evolving character of St Leonards.

“With a boundary length of almost 75m along Pacific Highway and 70m along Atchison Street to the north, complying simply with the LEP envelope and required setbacks would result in a very wide tower form on the skyline,” the architects noted in the Design Report.

“We propose breaking the tower form into two defined volumes rather than a singular form.”

The podium has similarly been articulated into separate forms to reduce perceived bulk and create a finer-grain response to Mitchell Plaza and Atchison Street. Retail tenancies would activate the lower levels, while commercial space is proposed across the podium floors.

<img alt="First look: Stockland plans 52-storey mixed-use tower with 538 apartments in St Leonards" data-entity-type="file" data-entity-uuid="90149990-0551-40d2-bd48-14b69a015d12" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/stockland%202.png?VersionId=MJC2KIIWFvU9FPGr3IVq09gkRN_gX3m8" />

The design also places a significant emphasis on communal amenity and environmental performance. Residents would have access to landscaped terraces, wellness areas, flexible workspaces, and rooftop communal facilities, while the all-electric building is targeting an average 7-star NatHERS rating. Bates Smart said the project incorporates passive design measures including natural ventilation, integrated shading, and lightweight façade systems.

Planning documents note the site is around 350 metres from St Leonards Station and 400 metres from the metro entrance, placing it within one of Sydney’s most connected emerging residential precincts.

The project arrives amid a wave of large-scale redevelopment proposals reshaping the St Leonards and Crows Nest skyline. Several nearby sites have recently been approved, lodged, or declared under the Housing Delivery Authority pathway as the precinct absorbs significant residential density uplift tied to transit-oriented development policies.

<img alt="Stockland" data-entity-type="file" data-entity-uuid="7805bd7c-dfd7-4b35-8e15-ec4a8bf8e61b" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/Screenshot%202026-05-20%20at%204.27.26%E2%80%AFPM.png?VersionId=iY12K2m2bQ6EeDnshqfZC9rbLx_oEugP" />

Bates Smart’s report describes St Leonards as transitioning away from its historical commercial identity toward a more mixed-use urban environment.

“In recent years, the character of St Leonards has started to evolve, driven by new development trends along the Pacific Highway corridor,” the report said.

“These projects have increasingly focused on residential accommodation, marking a shift from its purely commercial roots.”

Sekisui House Australia is currently selling Waterstone down near Newlands Park, in a pocket being branded "St Leonards South." Hyecorp recently completed Audrey in the same pocket.

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.
<img src="https://images.theconversation.com/files/356781/original/file-20200907-14-2qzvko.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt="Coal worker"> The technology may help prevent job losses in the coal industry. KYDPL KYODO/AP
<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>
