Gas-Free Magnetic Refrigeration for Sustainable Commercial Cooling and Food Preservation

environmentPilotedTRL 7

Imagine a fridge that doesn't use any chemical gases, but instead uses magnets and water to get cold. It works by using special materials that change temperature when a magnet moves near them. This replaces the noisy, polluting compressors found in traditional appliances with a solid-state system.

The business problem

What needed solving

Traditional refrigeration relies on F-gases that contribute to 7.8% of global greenhouse gas emissions and are being phased out due to high global warming potential or flammability.

The solution

What was built

A solid-state refrigeration system including 10 prototypes and a quality-tested domestic refrigerator using 3D-printed active magnet regenerators.

Who can put this to work

Retail & Grocery
enterprise
Target: Supermarket chain operator

If you are a supermarket operator dealing with high energy bills and strict F-gas regulations — this project developed a plug-in display cabinet that achieves 40% electricity savings.

Industrial Gas
mid-size
Target: Hydrogen fuel infrastructure provider

If you are a hydrogen provider dealing with the high energy cost of cooling gases — this project developed magnetic cooling power that is potentially viable for the hydrogen liquefaction chain.

Home Appliances
enterprise
Target: Domestic refrigerator manufacturer

If you are an appliance maker dealing with the phase-out of high-GWP gases like R-134a — this project developed a quality-tested domestic refrigerator that uses 0 GWP materials.

Frequently asked

Quick answers

How does this affect operational costs?

The technology is x3 more efficient than standard systems and achieves 40% electricity savings.

Is this ready for industrial scale?

Yes, the project developed the first industrially feasible refrigeration unit using a patented process to mass produce cheap magnetocaloric materials.

What is the IP status and licensing?

The technology relies on a patented process for producing performant and stable magnetocaloric materials based on research from TU Darmstadt.

How does it handle environmental regulations?

It eliminates dependence on high-GWP gases like R-134a and explosive gases like butane, resulting in 0 associated GWP.

What is the current development timeline?

The project ran from 2022-06-01 to 2025-01-31 and has already produced 10 prototypes.

Consortium

Who built it

The project is led by a single German SME, MAGNOTHERM SOLUTIONS GMBH, representing a 100% industry ratio. This lean structure suggests a highly focused commercialization drive, leveraging direct research transfers from TU Darmstadt to move from prototype to market without the overhead of a large academic consortium.
