HYDRO PURSUING ZERO-CARBON ALUMINIUM BY TESTING GREEN HYDROGEN TECHNOLOGY WITH GLOBAL POTENTIAL

Green hydrogen can replace fossil energy in the recycling of aluminium, enabling zero-carbon aluminium products. In a three year industrial scale pilot, Hydro will test green hydrogen technology in the new recycling unit at Hydro Høyanger, Norway.

R eplacing liquid natural gas with green hydrogen in the recycling of 100 percent post-consumer scrap is one of the fastest routes to zero-carbon aluminium. However, the remelting of aluminium requires high heat, an energy intensive process which is hard to achieve without fossil energy such as natural gas.

Hydro will be testing technology with global potential in this pilot, which is building on Hydro’s ‘world first’ industrial scale test of green hydrogen in aluminium recycling which took place in June 2023. “Hydro is pursuing multiple paths to decar bonize our operations. With this pilot we

take another step on our path to zero-carbon aluminium. Green hydrogen is an exciting potential option to decarbonize aluminium and other hard to abate industries,” says Hanne Simensen, Executive Vice President of Hydro Aluminium Metal.
