Not triggered by but relevant for The National Hydrogen Strategy of Germany, we are developing new efficient cooling systems for the cryogenic gas liquefaction which should help establishing hydrogen as an energy carrier which enhances and completes the great energy transition. Nowadays, the gas liquefaction is highly energy-consuming. Our recently work focuses on implementing magnetocaloric refrigeration for gas liquefaction. We studied the magnetocaloric effect on a representative of the Laves phase alloys, GdNi2, which is considered as a perspective material for liquefaction of natural gases. For a magnetic field change of 10 T, the magnetic entropy change ΔSm ≈ −17 J/kg K and the adiabatic temperature change ΔTad ≈ 6.8 K was attained around Curie temperature TC = 70 K. The maximal value of the adiabatic temperature change measured directly in pulsed magnetic fields up to 50 T is ΔTad ≈ 15 K.
