Heatcube:
Low-cost industrial heat
Who's Heatcube for?
Industry
Heatcube is made for industries requiring high-temperature process heat in the temperature range 150 – 300°C, such as food and beverage, pharmaceuticals, chemicals, manufacturing, and heavy industry.
It integrates seamlessly with existing steam infrastructure, enabling decarbonization and low-cost steam without disruption. Good for the world and you!
How Heatcube works
By electrifying heat
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 >93%, and a lifetime performance over 25+ years.
And with flexibility
Choose between Heat-as-a-Service (HaaS) — purchasing green steam without upfront investment, operational risk, or maintenance or Heat-as-a-Product (HaaP) to own and operate the system. Both models offer predictable pricing, long-term savings, and decarbonization.
Hassle-free heat
Heat-as-a-Service (HaaS)
Access clean, renewable heat with minimal upfront investment. Kyoto Group takes care of installation, operation, and maintenance while you simply pay only for the steam you use. This turnkey solution eliminates financial barriers and simplifies the transition to sustainable energy for your industry.
Operated by Kyoto
All HaaS solutions are managed by Kyoto Group, ensuring seamless operation and reliability. From energy storage to heat delivery, we handle every detail so you can focus on running your operatons efficiently.
Heat on your terms
Heat-as-a-Product (HaaP)
With Heat as a Product (HaaP), you gain ownership of a Heatcube, allowing you to produce renewable heat on-site. This solution integrates into your operations, delivering high-temperature heat while cutting emissions and energy costs. By adopting this technology, you turn sustainability into a valuable business asset.
A sustainable investment
Owning a Heatcube is an investment in energy independence and long-term cost savings. It empowers your business to reduce reliance on fossil fuels, meet sustainability goals, and position itself as a leader in clean energy adoption.
Low-cost heat

On-demand heat
Absorbs surplus electricity and delivers heat exactly when you need it, 24/7.
“We have had a really good and instructive collaboration with Kyoto Group, and this is a good example of what we want to do with our new test centre - to develop and demonstrate new, groundbreaking and green technologies in collaboration with companies, researchers and authorities.”
Søren Gais Kjeldsen, CEO of Aalborg Forsyning.
“Our aim is to rely entirely on sustainable energy in the future while ensuring lower energy costs. Kyoto’s Heatcube will provide us with a stable and cost-effective supply of sustainable process heat, and we are excited to get started with this project.”
Ádám Sass, Strategic Director of KALL Ingredients Kft.
