Sustainable process heating with high-temperature heat pumps using NatRefs

Solutions developed

The SuPrHeat project is an international R&D project aiming at the development of competitive and cost-effective high-temperature heat pump technologies for the supply of process heat demand of up to 200 °C at highest efficiencies for a variety of applications. By these developments, the project aims at facilitating the uptake of high-temperature heat pumps in industries in order to accelerate the decarbonization of industrial process heating.

Main results

The project entails developing three technologies based on water, CO2, and hydrocarbons, each with a 500 kW pilot plant. Testing will occur at DTI, followed by end-user demonstrations. Process integration improvements for industrial heat pumps are also prioritized, crucial for overall feasibility. Integration level and impacts on performance and investment costs are focal points, with existing facilities and novel equipment considered for process integration.
