Utility Scale Storage

Electriq and Zenith Energy Terminals are teaming up on hydrogen powder production in Amsterdam, while Universal Hydrogen has completed the world’s first passenger flight based on hydrogen fuel cell propulsion.

An international group of researchers has designed a new hybrid photovoltaic-liquid air energy storage (PV-LAES) system. Their economic evaluation for the proposed 2 MW PV-LAES project showed that the investment payback period can be within 10 years, and the accumulated net profit can reach up to $2.2 million from a life-cycle perspective.

Smartville has secured $5.9 million from the US Department of Energy to scale its second-life battery program.

The remote town of William Creek in the Australian outback is now entirely powered by solar backed by a battery energy storage system, after the switch was flicked on a 200 kW PV array that eliminates the need for diesel generation.

Battery energy storage saw a major increase in contracted capacity in British auctions this year, with many utility-scale projects securing long-term deals. The business case, however, is not as strong for all storage durations.

Scientists in Sweden have proposed the use of excess wind and solar power to incinerate metals such as aluminum and iron, in order to produce heat that could be used to generate electricity or hydrogen.

BMW has launched its iX5 Hydrogen vehicle pilot fleet, with plans to start production by the end of the decade. Everfuel and Hy24, meanwhile, have launched a joint venture to accelerate hydrogen development in Scandinavia.

US researchers have developed a new lithium-air battery with solid electrolyte and the potential to reach a record energy density that is nearly four times that of lithium-ion batteries. The test cell demonstrated stability over 1,000 charge and discharge cycles.

Karnataka Ltd. has started accepting bids to develop up to 1 GW of pumped hydro storage, while Assam Power Distribution has revealed plans to procure 200 MW of PV capacity.

US engineers have built a scalable thermal energy storage prototype system that combines the best latent and sensible heat transfers. The technology, which is now market-ready after three years of testing, consists of engineered cementitious materials and thermosiphons in a combination that enables fast, efficient thermal performance at low cost.
