Redoxblox, a developer of low-cost thermochemical energy storage systems, raised an additional $30M in Series A funding, led by Prelude Ventures and joined by Imperative Ventures and New System Ventures, alongside existing investors Breakthrough Energy Ventures and Khosla Ventures. This brings the total Series A round to $40.7M.

Redoxblox is pioneering a new class of low-cost thermochemical energy storage systems (TCES) designed to accelerate industrial decarbonization and address long duration energy storage needs for the grid. The company's TCES units store energy both chemically and as heat at high temperatures, allowing for continuous or on-demand discharge for industrial processes or electricity generation. The system can fast charge when electricity prices are low or during periods of surplus renewables generation.
