Queensland company Green Day Energy has begun trialling its proposition to convert the invasive weeds species, prickly acacia, to biomass for the purpose of generating electricity, biochar and hydrogen.

Tesla has increased the price of its Powerwall solar battery system by almost a grand, taking the total – before installation – to $13,700.

Queensland-based company Line Hydrogen is launching its inaugural $100 million green hydrogen project in the growing hub of Bell Bay in Tasmania’s north. With a solar offtake agreement in place, the startup is aiming to be in production within a year.

On Friday, major changes to the regulatory framework surrounding the small-scale renewable energy scheme (SRES), effectively the country’s solar rebate program, will come into force. Pv magazine Australia spoke to Smart Energy Council CEO John Grimes about the changes and how they will impact Australia’s solar players.

Western Australian company Infinite Blue Energy has today announced it will purchase Northam solar farm, which sits an hour east of Perth. The acquisition will accelerate the company’s green hydrogen project as it aims to produce up to 4.4 tonnes of renewable hydrogen daily from next year.

A West Australian joint venture seeking to recover high-purity vanadium from a steel industry waste product using a carbon negative process has won the support of the European Union. “We’re not the first people to look at that project, but we’re the first people to look at it through a different lens and use this type of process,” Neometals’ General Manager of Commercial and Investor Relations, Jeremy McManus, told pv magazine Australia. The project, which is still in the early stages, is already been sought out by potential offtakers “desperate to secure green vanadium,” McManus added.

The deal between Fortescue Future Industries and E.ON, one of Europe’s largest energy network operators, will see the Australian company deliver five million tonnes of green hydrogen to Germany, the Netherlands and other European cities by 2030. “For us, it’s a minimum $50 billion expenditure. And that is one I welcome,” Fortescue founder Andrew Forrest said at press conference in Berlin overnight.

Australian fossil fuels giant Woodside will invest in US-based concentrated solar startup Heliogen, supporting its construction of a full-scale concentrated solar thermal demonstration plant in California ahead of a push into Australia.

A standing committee has blocked federal energy minister Angus Taylor’s longstanding attempts to allow ARENA to fund fossil fuel projects, finding it illegal. The ruling came on the same day new analysis found the Morrison government’s fossil fuel subsidies increased 12% in FY22, costing taxpayers a total of $10.5 billion.

Traditionally one of the slower states to move away from fossil fuels, New South Wales is rapidly turning the tables – and the market is responding enthusiastically. The state government yesterday revealed it had received more than $4 billion worth of investment interest for its Hunter and Illawarra hydrogen hubs.
