Hydrogen

Queensland government-owned generator Stanwell Energy and Japan’s largest hydrogen supplier Iwatani Corporation are preparing to commence a Front-End Engineering Design study as they drive towards a final investment decision on a 3 GW green hydrogen project being developed near Gladstone on the central Queensland coast.

Researchers from RMIT and the University of Melbourne have discovered high-frequency vibrations can release 14 times more hydrogen compared with standard electrolysis techniques. The discovery also has ramifications for the expensive, rare materials currently used in electrolysers. “With sound waves making it much easier to extract hydrogen from water, it eliminates the need to use corrosive electrolytes and expensive electrodes such as platinum or iridium,” research lead Amgad Rezk said.

The International Energy Agency says that it expects the use of renewables to support global hydrogen production to surge over the next five years. The Netherlands and Denmark, meanwhile, have revealed plans to expand electrolysis capacity.

South Korean steel producer Posco Group will invest $60 billion (USD 40b) in Australia by 2040 across the green steel supply chain, including in renewable generation, electrolysis and steel making processes.

The Western Australian government has made a number of announcements at a hydrogen conference held in its capital on Tuesday, December 6, including a commitment to streamline project approvals, releasing new policy and guidance for Crown land use, and an update to the state target of having green hydrogen comprise 1% of the generation in the state’s main grid.

Energy consultancy Xodus Group has announced plans to develop an export-scale green hydrogen project in the Mid-West region of Western Australia which will scale up to 1 GW of electrolyser capacity.

A holiday house in New South Wales is thought to be the first residential property in Australia to make the switch to a hybrid solar and green hydrogen standalone power system with network service provider Essential Energy trialling the off-grid technology.

Australian renewables developer Energy Estate has signed a consortium of “globally recognised partners” to accelerate the development of a large-scale green hydrogen and ammonia production and export facility in north Queensland.

Woodside has won out over Fortescue Future Industries to deliver the proposed Southern Green Hydrogen megaproject in New Zealand’s Southland. The 600 MW project intends to produce green hydrogen for export using power from partner Meridian Energy’s hydroelectric plant.

Queensland-based ReNu Energy has announced “firm commitments” for a capital raising of $4.5 million (USD 3 million) which it says will progress its green hydrogen projects in both Brighton and Launceston in Tasmania, as well as in Indonesia’s Riau Archipelago.
