Kyoto Group

We decarbonize process heat. At scale. For Industry.
The future of industrial heat is fossil-free and it’s arriving faster than ever.

At Kyoto Group, we accelerate this shift by replacing fossil-fired boilers with Heatcube, our flexible thermal battery that delivers clean, on-demand heat to meet industrial needs.

Heatcube charges when electricity prices are low, storing energy as high-temperature heat using safe, non-toxic molten salt. It then discharges steam on demand, with a round-trip efficiency of more than 93%, and a lifetime performance over 25+ years.

Choose between Heat-as-a-Service — purchasing green steam without upfront investment, operational risk, or maintenance or Heat-as-a-Product to own and operate the system. Both models offer predictable pricing, long-term savings, and decarbonization.
