MagHeat is developing a next-generation solid-state refrigeration system using liquid metal heat transfer and a novel rotating iron-insert magnet assembly — delivering 30% cost reduction and 50% less critical raw materials.
Heating and cooling account for 50% of the EU's total energy consumption, with 75% of heating demand met by natural gas. Heat pumps are critical — but existing magnetic refrigeration technology faces fundamental barriers to widespread adoption.
MagHeat tackles all three hurdles simultaneously through a novel permanent magnet assembly with a rotating iron insert, combined with liquid metal (Ga-In-Sn alloy) as heat transfer fluid — an industry first.
Starting at TRL 3, MagHeat will advance to TRL 5 across magnet design, material development, and full system integration — delivering a working prototype with 10 K temperature span and 100 W cooling power.
MagHeat's rollout follows a two-phase strategy: initial deployment in supermarket refrigeration, followed by expansion into domestic heat pumps — targeting markets valued at €73 billion by 2050.
MagHeat unites three leading universities and three innovative SMEs across the Netherlands, Portugal, and Denmark — combining world-class expertise in magnetocaloric materials, magnet design, manufacturing, and market deployment.
MagHeat actively participates in the CETPartnership Knowledge Community — the mandatory collaborative network for all CETP-funded projects. All results are shared openly to accelerate Europe's clean energy transition.
