What we do
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.
As a trusted partner to energy-intensive sectors, we provide cost-effective, decarbonized process heat that helps industry scale sustainably and transition away from fossil fuels.
Our approach
Kyoto Group is driven by a clear purpose: to accelerate industrial decarbonization by making clean heat accessible, affordable, and easy to adopt.
We focus on energy-intensive sectors — industries that rely on heat to produce the world’s food, materials, and goods because that’s where the climate impact is greatest. These industries face real pressure to cut emissions without disrupting operations. We make that shift possible.
Our Heat-as-a-Service offer is the perfect solution to the industry's transition needs. By managing the full lifecycle, we simplify integration and ensure performance. Our modular thermal battery, Heatcube, fits seamlessly into existing systems and is supported by monitoring, optimization and energy management.
Kyoto’s approach is practical, partnership-driven, and built for scale.
Where we began
Since our founding in 2016 in Oslo, Norway, Kyoto Group has established a presence in Seville, Spain.
Over the past nine years, we’ve grown our international footprint through the acquisition of Mercury Energy in 2022, which led to the creation of Kyoto Technology Spain, and by deploying two commercial Heatcubes across Europe.
In 2024, Glentra Capital became our principal owner. Founded in 2022, Glentra is a Danish energy fund dedicated to accelerating the green transition through decarbonization and energy efficiency.
With deep expertise in energy infrastructure and long-term capital, Glentra supports the scale-up of Kyoto’s Heat-as-a-Service model, enabling faster Heatcube deployment and greater impact for energy-intensive industries.
Expanding our vision
Kyoto Group leads the thermal battery industry, with more than 70 MWh of installed storage capacity and 40–50 GWh of annual heat supply already in operation in Europe, along with a strong pipeline of projects currently underway.
This momentum is driven by a global market opportunity of over 11,200 TWh in electrifiable industrial heat, representing 3,700 GW of potential demand response capacity*.
Positioned at the intersection of energy, industry, and infrastructure, Kyoto is enabling manufacturers to load shift, stabilize power markets, and decouple heat generation from fossil fuels.

Care
We are a caring company aiming to solve the world's biggest problem, and take care of our team.
Enthusiasm
Enthusiasm fuels the drive we need to achieve success. More than identifying holes in the cheese.
Determination
What we are doing, has never been done before. It may be a bumpy road, but determination will see us through.
