Tempo (formerly Redoxblox) provides thermochemical energy storage (TCES) solutions to decarbonize high-temperature industrial processes. Using modular "thermochemical batteries" made from non-toxic metal oxides, Tempo enables operators to store low-cost renewable energy and discharge continuous heat up to 1,200°C. Backed by Breakthrough Energy Ventures and Khosla Ventures, the San Diego-based firm offers a cost-competitive, electrified alternative to fossil fuel combustion for sectors like cement, metals, and food and beverage.
