Industrial heat is responsible for more than 20% of global CO2 emissions, because it relies on relatively cheap fossil fuel combustion.

Clean and affordable alternatives are needed to keep on track with climate objectives while generating value.

Airthium offers turnkey clean industrial heat solutions to help its customers hit their decarbonization targets and ESG goals in the most economical way.
We leverage the potential of our very-high-temperature heat pump to enable profitable decarbonization of the 150°C-550°C industrial heat segment, a $13B/y Total Addressable Market (CAPEX only).
Currently available heat pump technologies are limited to a maximum supply temperature of 160°C, which leaves a lot of untapped market potential for Airthium and represent tens of thousands of units to be installed in the coming decades worldwide.

We are dedicated to help our customers in the food & beverages, paper, minerals and mining industries optimizing their processes’ energy efficiency and reducing their environmental footprint profitably.

Trusted partners allow us to offer innovative financing solutions by means of dedicated lease or heat supply contracts to our customers, in order to minimize their capital investment and accelerate their decarbonization at comparably low cost.

A Dutch brewery aims to minimize its energy consumption and carbon footprint. We propose replacing its gas boiler with our HTHP technology.
Operating conditions
  • Process temperature is 180 °C
  • It requires about 15 MW of heat at this temperature
  • There is waste heat available at 75 °C from the pasteurization process
  • The site operates continuously with just two maintenance days per year
  • The facility pays 52 €/MWh for gas1
  • It is subject to a carbon tax of 65 €/tCO2
  • The national electricity mix releases 418 gCO2/kWh3
Airthium’s HTHP reaches a COP of 2.2
By replacing the gas boiler with the HTHP, the brewery saves 5 300 tCO2 per year and 5% on its energy bill.
Airthium would be profitable by invoicing the brewery only 65.7 €/MWh for heat. Electricity would come from a Power Purchase Agreement (PPA) of 52 €/MWh, covering 10% of the electricity consumption, while the remainder would be sourced at an average price of 136 €/MWh2.
