Iron flow battery company ESS Tech Inc (ESS Inc) has warned of substantial doubts about its ability to survive another year.

Energy storage developer and system integrator Energy Vault has received approval to pursue market-based participation in the California Independent System Operator (CAISO) with the Calistoga Resiliency Centre (CRC).

“We need some form of policy or expansion of the CIS for LDES,” Nick Hawke, director of Australia’s CEFC, tells ESN Premium.

US zinc battery and energy storage system maker Eos Energy Enterprises has reported year-on-year revenue growth of 243% from the first half of 2024.

Following recent progress for long-duration energy storage projects in California, Terra-Gen has entered the fray with its huge 8GWh hybrid BESS project.

California’s largest electric utility is continuing its push to establish a net-zero energy system by 2040, finalising an offtake agreement for 1.8GWh of battery storage capacity with Aypa Power.

Google has partnered with and made a strategic investment in carbon dioxide-based long-duration energy storage (LDES) company Energy Dome.

Steady price falls the past few years have made lithium-ion BESS a real contender for long-duration energy storage (LDES), and that is now reflected in global project pipelines.

Tom Sisto, CEO of US flow battery provider XL Batteries, writes that lithium-ion batteries’ dependence on a supply chain controlled almost completely by one country is a risk that could be avoided.

Invinity Energy Systems believes partnering with a Chinese materials and manufacturing company will enable significant cost reduction of its vanadium redox flow battery (VRFB) technology.
