Energy Storage

Honda has revealed a new hydrogen strategy, while Air Liquide and TotalEnergies have announced a new hydrogen joint venture.

US residential solar specialist Sunnova is seeking approval from the California Public Utilities Commission (CPUC) for its micro-utility business model, which could potentially disrupt the state’s energy landscape. pv magazine speaks to CEO John Berger about plans to develop self-sustaining microgrids by equipping new homes and communities with solar and storage.

Scientists in Sweden have compared AC and DC topologies in PV-powered buildings using battery storage. They have found that DC distribution systems can achieve energy savings when they are combined with solar-plus-storage systems.

Chinese scientists have analyzed reports of thermal issues with vanadium redox flow batteries (VRFB) and existing thermal management methods. They say the operating temperature should be maintained in the range of 10 C to 40 C to ensure VRFBs with high efficiency, weak side reactions, high electrolyte stability, and low crossover.

Enphase’s new bidirectional EV charger enables vehicle-to-home and vehicle-to-grid applications, and can be integrated with its home energy systems.

Storage Hub founder Oliver Schmidt speaks with pv magazine about his outlook for battery energy storage pricing and the cost trajectory of electrolyzers. Schmidt’s new book, “Monetizing Energy Storage – A toolkit to assess future cost and value,” will be published by Oxford University Press in June.

As the US Uyghur Forced Labor Prevention Act demonstrated, companies preparing to spend big on batteries are at risk of being blindsided by supply-chain-related legislation. Here are some tips on how US developers can anticipate policy curveballs.

Just weeks after announcing its intent to build a AUD 300 million ($210 million) lithium-ion battery manufacturing facility in Australia, Recharge Industries has reportedly joined a host of other bidders considering the revival of collapsed UK battery company Britishvolt. Investment could also revive plans to construct a battery cell gigafactory in northern England.

Low participation rates for vehicle-to-grid (V2G) tech of just 12% to 43% are needed to provide short-term grid storage demand throughout the world by as early as 2030, according to a group of Dutch and US researchers.

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