Shell Plc (LON:SHEL) said on Wednesday it has struck a deal to offtake around 75% of the output of a 230-MW solar project in Germany to secure the electricity supply of its 100-MW Refhyne II proton-exchange membrane (PEM) electrolyser.

The power purchase agreement (PPA) with Solarkraftwerk Halenbeck-Rohlsd has a 10-year term and complements a five-year deal for roughly a third of the output of the 332-MW Nordsee One offshore wind farm in the German North Sea.

The contracted photovoltaic (PV) project is currently under construction and will create two identical plants of 115 MW each. Its owner is 50%-owned by Deutsche Anlagen-Leasing (DAL).

The two PPAs signed by Shell Energy Europe Limited secure “a significant proportion” of the renewable electricity required for REFHYNE 2’s operations. The hydrogen electrolyser is currently being installed near the company’s Energy and Chemicals Park Rheinland near Cologne, Western Germany. Once in operation in 2027, it will have the capacity to produce up to 16,000 tonnes of renewable hydrogen every year for use to partly decarbonise Shell’s operations.
