About Tempo Innovations, Inc.

Based in San Diego, California, Tempo develops thermochemical energy storage (TCES) systems designed for energy-intensive industries. The platform enables industrial operators to shift energy use over time by sourcing power when it is most cost-effective and enables the electrification of high-temperature industrial heat at a cost advantage to using fossil fuels. By storing electricity thermochemically, the system delivers a continuous stream of combustion-free, high-temperature air at up to 1,200°C.

Tempo is backed by leading climate and energy investors, including Breakthrough Energy Ventures, Khosla Ventures, and Prelude Ventures.

About Tempo

Located in San Diego, Tempo 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 very high temperatures that can be discharged continuously or as needed directly into industrial processes or as an energy source for electricity generation. The system can be fast charged when electricity prices are low or during surplus renewables generation and discharged as needed. Tempo is backed by Prelude Ventures, Khosla Ventures, Breakthrough Energy Ventures, Imperative Ventures, and New System Ventures.
