Germany's RWE has announced a significant agreement to supply French oil major TotalEnergies with around 30,000 tonnes of green hydrogen per year starting from 2030. The deal, projected to run until 2044, represents one of the largest contracts for carbon-neutral hydrogen from a German electrolysis facility. This partnership aims to decarbonize TotalEnergies' Leuna refinery in eastern Germany using hydrogen produced by RWE's electrolysis plant in Lingen. Despite growing skepticism around the costs of green hydrogen projects in Europe, this agreement showcases the potential of hydrogen as a viable solution for customers. It also expands the collaboration between RWE and TotalEnergies beyond offshore wind into the realm of green hydrogen. The use of renewable electricity for hydrogen production highlights its environmental benefits, as it generates only water and oxygen as byproducts when burned. RWE plans to utilize a hydrogen storage facility for supply and transportation to Leuna through Germany's developing hydrogen network. This initiative signifies a step towards achieving decarbonization goals in the energy sector.
