We decarbonize high-temperature
industrial heat.

Our mission

is to competitively replace fossil fuels in energy intensive industries by converting renewable electricity into storable, high-temperature process heat.

11% of global CO2 emissions is caused by
high-temperature industrial heat.

No carbon-neutral, cost-competitive and easy to integrate solution exists yet.

Our solution

The Heatrix system combines an electric heater, utilizing off-grid solar or wind electricity, with a thermal energy storage to provide continuous high-temperature process heat. With an outlet temperature of up to 1500 °C, Heatrix has the potential to decarbonize the majority of high emission industries.

Heatrix technology perfectly fulfils customers' requirements – CO2 free continuous and easily integrated process heat at competitive cost.

Carbon-free green heat,
reducing CO2 emissions
up to 100%

Process heat (hot air)
up to 1500 °C

Thermal storage up
to 20 hours to
deliver green heat 24/7

High efficiency up
to 90% based on
resistance heating

Cost competitive vs.
fossil fuels and substantially
cheaper than green hydrogen

Modular container
system enables
easy scalability

Easy integration
with minimal
retrofitting needs

Applications for Heatrix


Replacing fossil fuel burners and reducing fuel consumption in calcination processes by integrating Heatrix heat to shaft calciners or precalciners of rotary kilns.

Heat Treatment

Inducing required process temperatures via hot air flow from Heatrix replacing fossil fuel burners in heat treatment ovens.

Sintering & Pelletization

Reduced fuel gas & coke usage by providing Heatrix heat to sintering or pelletization plants.


Combined with existing burner system, Heatrix technology can be used to preheat materials and reduce fuel consumption in the actual process.
