Hydrogen

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.

Frontier Energy’s plans to produce green hydrogen powered by renewable energy sourced from the potential 500 MW Bristol Springs Solar project it is developing in Western Australia has received a major boost with a study revealing the cost of hydrogen production could be as low as $2.85 per kilogram.

Mitsubishi Power Americas and Magnum Development are set to begin construction on a 300 GWh underground storage facility in the US state of Utah. It will consist of two caverns with capacities of 150 GWh, to store hydrogen generated by an adjacent 840 MW hydrogen-capable gas turbine combined cycle power plant.

The system is reportedly able to refill about eight hydrogen fuel cell vehicles, each in three minutes. It is also able to supply electric power by using hydrogen produced with renewable energy within the station.

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.

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.

A Spanish scientist has developed a system that reportedly produces hydrogen on-site without expensive electrolysis. The prototype utilises a water tank that is initially filled with water, ferrosilicon, and sodium hydroxide.

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.

Australia is setting out to become a global hydrogen superpower – but the standards we’re applying to classify ‘green’ renewable hydrogen are falling well behind our global peers and the expectations of future customers. The heart of the problem is “we’ve separated the characteristics of energy from the energy itself,” Steve Hoy, founder and CEO of power tracing technology company Enosi, tells pv magazine Australia.
