Redoxblox Closes $40.7 Million Series A to Support Industrial Decarbonization and Grid Storage with Next-Gen Thermochemical Energy Storage System
Redoxblox 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.
95% of industrial heat is provided by fossil fuels, which accounts for 30% of global carbon emissions. Decarbonizing this sector has been historically challenging due to a lack of affordable emissions-free alternatives. With a conversion efficiency comparable to lithium-ion batteries, higher energy density, and direct high temperature air discharge, Redoxblox provides the first reliable, cost-competitive solution to effectively use electricity as an alternative to fossil fuels. The system also offers space efficient, grid-scale long duration energy storage, enabling intermittent renewables to meet baseload needs.
