Energy Storage

Professor Thomas Nann told pv magazine Australia that a breakthrough idea was almost too simple: “Actually when we submitted the patent in the first place, the patent officers came back to us and said ‘well, that’s too trivial’ and we made exactly that argument – why did no one else do that then?” said Nann.

With Australia prepping plans for vast green hydrogen and ammonia production facilities, two of the country’s state governments are trying to drum up the end-user market as agreements are signed to drive use of the gas in Ukraine and Poland.

U.S.-owned, Nairobi-based mini-grid developer PowerGen has already rolled out seven local solar networks in the West African country, funded by equity investors who will recoup their cash when all 28 systems are sold to CrossBoundary Energy Access.

Known as Australia’s “Sunshine State,” Queensland households have, in just two years, doubled their residential energy storage, according to a new survey. The figures reveal 37% of Queensland households now have panels installed, with a further 22% looking to install or upgrade their systems.

New tech which can store power for longer than four hours can secure up to €14 million each towards their demonstrator project costs.

Made up of distributed residential energy storage, these “plants” stabilize the grid and often end the need for new fossil generation. Tesla customers in California are the latest to join the movement.

U.S.-based Hyzon Motors has developed a new onboard hydrogen storage system technology capable of reducing the weight and manufacturing cost of commercial vehicles powered by hydrogen fuel cells. Meanwhile, India’s largest oil provider has announced its first green hydrogen project and the Dutch government has awarded a subsidy contract to an offshore green hydrogen demonstrator.

Australia’s first lithium-ion battery manufacturer, Energy Renaissance, has received a grant to develop its pilot manufacturing facility in the Hunter region.

The system can be expanded to a capacity of up to 25 kW. Its creator – U.S.-based start-up EcoFlow – has already collected almost €4 million on the Kickstarter crowdfunding platform for its portable power supply solution.

Western Australian company Australian Vanadium Limited has been awarded $3.69 million in federal government funding to fast-track manufacturing of large-scale vanadium redox flow battery systems that can be used to support rooftop solar PV or in off-grid settings such as mining, agriculture and remote communities.
