US engineering company Bechtel will support planning for proposed Queensland pumped hydro and energy storage facility, Big-T, at Lake Cressbrook in the state’s southeast. The project involves a 400 MW pumped hydro facility with 10 hours of storage and a 200 MW/200 MWh battery system.

Bringing on board gas giants APA Group, Inpex Corporation, Osaka Gas and distributor Jemena, AGL and Fortescue Future Industries say their Hunter Valley coal to hydrogen hub conversions could be as large as 2 GW – though the insistence on green hydrogen does appear somewhat muddied by the new partnerships.

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.

French company Neoen has seen its storage revenue “more than tripled” as a result of its recently commissioned Victorian Big Battery coupled with Australia’s energy crisis. In other news, the company signed a 10 year power offtake agreement with Flow Power for its “flagship” Goyder Renewables Zone project in South Australia.

Australian mining technology company TNG Limited, which owns the world’s most advanced vanadium project – the Mount Peake Project in the Northern Territory, is having its leadership team formally challenged by a shareholder campaign criticising the project’s setbacks and slow progression.

The Northern Territory is set to install its first hydrogen energy storage system as part of a pilot being operated by the Charles Darwin University in Darwin.

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.

West Australian natural hydrogen startup H2EX will work with Australia’s national science agency, the CSIRO, to study natural hydrogen systems in South Australia’s Eyre Peninsula, describing the research as a “pivotal first step” for the nascent industry. Natural hydrogen proponents believe projects could deliver some of the world’s cheapest hydrogen quickly and with a minimal footprint.
