Hydrogen

Australian renewable hydrogen company Infinite Green Energy is targeting first commercial-scale production of green hydrogen by the end of 2024 after finalising the $8 million (USD 5.65 million) acquisition of an 11 MW solar farm in Western Australia and penning its first offtake agreement for the project.

The hydrogen stream: ZeroAvia tested its new 19-seat hydrogen-powered aircraft, Chinese scientists unveiled new tech to promote bubble removal in electrolysers, and Egypt-Japan University of Science and Technology researchers claimed that the most efficient hydrogen production systems are based on waste heat.

Japan’s largest oil company, Eneos, has opened a green hydrogen demonstration plant at Bulwer Island in Brisbane. While the scale of the project is relatively small, producing just 20 kilograms of green hydrogen a day, Eneos Senior Vice President Yuichiro Fujiyama says the company will expand the project’s scale “in near future.”

A Victorian-based startup which claims to have developed a hydrogen enhancement kit that injects hydrogen into existing diesel engines to reduce diesel use, has begun the production of 10 commercial-ready systems. It will do field testing with the systems on sites of potential customers.

Researchers from the University of Adelaide, along with international partners, have successfully used seawater with no pre-treatment to produce green hydrogen. The team did this by introducing an acid layer over the catalysts in situ. “We have split natural seawater into oxygen and hydrogen with nearly 100% efficiency… using a non-precious and cheap catalyst in a commercial electrolyser,” University of Adelaide’s Professor Shizhang Qiao said.

An Australian cleantech company that claims its technology could enable hydrogen production of below $1.50 per kilogram by the middle of the decade is one of four green fuel projects to share in more than $100 million (USD 78 million) funding awarded as part of a collaboration between the Australian and German governments.

The World Future Energy Summit showed that Middle Eastern solar markets are still driven by utility-scale PV, although the C&I sector shows signs of growth. Saudi Arabia, Egypt and the United Arab Emirates are the most promising markets for big solar projects, with huge pipelines under development, while Lebanon and Yemen show promise due to chronic energy shortages.

An educational event series aimed at upskilling engineers to enter the hydrogen industry is launching in February in Melbourne. The Hydrogen Industry Technical Series 2023 is being organised by the Victorian divisions of the Australian Institute of Energy and Engineers Australia.

The Australian government has unveiled a $70 million (USD 49 million) investment to aid the development of a green hydrogen hub in the north Queensland city of Townsville as it looks unlock the benefits of an industry which it says could inject an additional $50 billion (USD 35 billion) into the economy by 2050.

For a long while, it looked as if hydrogen fuel cells would be the technology of choice for emissions-free road transport. However, truck manufacturers and freight forwarders recently turned their attention to battery-electric vehicles. This will require special charging technology and PV looks set to play an important role.
