Energy Storage

Salgenx has developed a way to produce graphene on demand from its saltwater flow battery. The tech exploits the electrochemical properties of the battery’s cathode to exfoliate graphite into individual layers of graphene. The company says it can produce graphene for less than $1.25 per gram, providing storage businesses with an additional revenue stream.

Low electrolyzer costs, low capex, a low levelized cost of energy, and a decent capacity factor are key to developing viable green hydrogen projects. George Touloupas, senior director of technology for Clean Energy Associates, tells pv magazine about the main challenges and the current price trajectory for green hydrogen tech.

Tesla releases its third Master Plan, with a broad focus on clean electricity generation and storage, as well as related manufacturing costs.

Generac says its new zero-emissions SBE line of stationary storage systems will be available in capacities ranging from 200 kWh to 1,000 kWh.

Viessmann’s new sub-distribution system links various components and connects them to the power grid. Its Wallbox has a charging capacity of 11 kW (three-phase) and is equipped with a 7.5-meter “Type 2” charging cable.

A team of US researchers engineered a double-membrane system to minimize chloride oxidizing the anode. Meanwhile, the Spanish government supports Destinus to develop its hydrogen-powered supersonic plane and test it in 2024.

Japan’s Toshiba has shared the results of a “future-proof” housing project in the United Kingdom. It combined two 11 kW air-source heat pumps in a five-bedroom house in Chester, England, with a 16 kW PV system and an 11 kW battery. The property is reportedly energy neutral in the summer months.

EntX has secured a license to explore salt deposits along the western side of the Eyre Peninsula in South Australia for the purpose of hydrogen storage.

Idemitsu Kosan is leading a four-year demonstrator to assess the viability of solar carports for EV recharging at Tanegashima Airport in Japan. The 54.7 kW solar facility will sell power to airport buildings via a power purchase agreement (PPA) and to EV users under a pay-as-you-go billing system.

Renewables developer GMR Energy has started working on a 240 MW/480 MWh battery project in Victoria, Australia.
