Miner Rio Tinto has received offers to build more than 4 GW of solar and wind capacity after the company sought proposals to help it cut carbon emissions at its Queensland operations.

Fourth-generation Victorian dairy farmers this week commissioned their 250kW rooftop solar system coupled with 520 kWh of battery storage from Australian company Energy Renaissance. The couple are forecast to save at least $70,000 annually with the system, cutting their grid reliance by 95% and hopefully inspiring neighbouring farms.

Australian hydrogen tech company Hysata has raised over $40 million in funding, attracting backing from major institutional players including CEFC, Hostplus and Bluescope. Hysata is seeking to commercialise a breakthrough made at the University of Wollongong which CEO Paul Barrett describes as “brand new category of electrolyser” with 95% system efficiency.

Wood Mackenzie places Australia fourth on its list of the globe’s top 10 storage markets, coming in just behind Germany, with the US and China unsurprisingly topping the list. The analyst expects the world’s cumulative storage deployments to reach 500 GW by 2031, according to its Global Energy Storage Outlook released today.

In other news, German energy company Uniper said it will test a new salt cavern built for hydrogen storage, while Serbia and Hungary signed a memorandum of understanding to collaborate on renewable hydrogen.

South Australia’s 150 MW / 193.5 Hornsdale Power Reserve, more commonly known as the Tesla Big Battery, will now provide inertia services to Australia’s National Electricity Market after securing approval from AEMO. Neoen says it is the first big battery in the world to deliver the service at such a scale.

Tesla chair Robyn Denholm expects the company to double its EV sales in Australia by the year’s end, hoping to see its flagship product catch up to its Powerwall sales. Denholm also said Australia needs to expand its lithium refining and processing capacity at “sprinting pace” to properly capture the global battery opportunity.

Researchers at Melbourne’s Deakin University have discovered a novel way to separate, store and transport large amounts of gas. The method, they say, is efficient, affordable and creates no waste – carrying huge implications for the burgeoning green hydrogen industry and for the energy transition at large.

Project Symphony provides a glimpse into Western Australia’s energy future, argues the project’s communications lead, Megan Allan. With a large, islanded network featuring high levels of rooftop PV penetration, the pilot on Western Australia’s grid is aggregating residential PV into a virtual power plant (VPP) to participate in a simulated bidirectional wholesale electricity market.

Speaking at the Sydney Energy Forum, leaders from Australia and the US have highlighted the importance of not only transitioning to renewables, but of ensuring the supply chains used to make the technologies do not remain as concentrated as they are today.
