Battery storage

A report from Leeward Renewable Energy has investigated battery energy storage system (BESS) fires and other thermal runaway events to try and put them into context.

Korean scientists have designed a liquid air energy storage (LAES) technology that reportedly overcomes the major limitation of LAES systems – their relatively low round-trip efficiency. The novel system enhances efficiency by increasing power output through the generation of thermal energy using natural gas as the external fuel during energy release.

Similar to last year, battery energy storage systems (BESS) made up almost all new-build capacity selected in recent Capacity Remuneration Mechanism (CRM) auctions in Belgium. Simon De Clercq, senior research associate at Aurora Energy Research, tells ESS News that there is even more room for BESS players to participate in the procurement exercises.

Eaton says its new xStorage commercial and industrial battery energy storage system (BESS) offers storage capacities ranging from 250 kWh to 1,000 kWh, using lithium iron phosphate batteries with self-contained liquid cooling.

Western Australia’s state-owned regional energy provider Horizon Power has officially launched the trial of a vanadium flow battery in the northern part of the state as it investigates how to integrate long-duration energy storage into its network, microgrids, and other off-grid power systems.

A new approach aims to reconnect commercial and industrial (C&I) energy users to the grid, supplying daytime power from solar and batteries through grid infrastructure funded by PV installers, with diesel as a backup when needed.

Company co-founder Peter Carlsson steps down from CEO position at Northvolt in the wake of Chapter 11 announcement in the United States. The Swedish battery maker has embarked on a debt restructuring process and is seeking new sources of funding.

Brazil’s largest microgrid has gone online at the State University of Campinas (Unicamp). The CampusGrid project combines a 565 kW solar system with a 1 MW high-capacity battery energy storage system (BESS).

German manufacturer Solarwatt says its new battery can be flexibly configured as an AC or DC system. It also features an emergency power function and can only be combined with Solarwatt inverters.

China-based Envision Energy says that its 5.5 MW /14 MWh grid forming energy storage demonstration platform is the first and biggest single-unit grid-forming energy storage system globally to receive certification under rigorous, full-scenario testing standards.
