Germany: Green Hydrogen Europe’s Largest PEM Hydrogen Electrolyzer Commences Operations

Editor: Ahlam Rais

Located at Shell’s Energy and Chemicals Park Rheinland, near Cologne in Germany, the mega project is part of the Refhyne European consortium which will utilize the PEM technology to produce green hydrogen.

The Hague/The Netherlands – The project, backed by a European consortium, will accelerate hydrogen production and contribute to Europe’s goal to achieve climate neutrality. Europe’s largest PEM (Polymer electrolyte membrane) hydrogen electrolyzer, recently began operations at Shell’s Energy and Chemicals Park Rheinland, producing green hydrogen.

As part of the Refhyne European consortium and with European Commission funding through the Fuel Cells and Hydrogen Joint Undertaking (FCH JU), the fully operational plant is the first to use this technology at such a large scale in a refinery. Plans are under way to expand capacity of the electrolyzer from 10 megawatts to 100 megawatts at the Rheinland site, near Cologne, where Shell also intends to produce sustainable aviation fuel (SAF) using renewable power and biomass in the future. A plant for liquefied renewable natural gas (bio-LNG) is also in development.

This project demonstrates a new kind of energy future and a model of lower-carbon energy production that can be replicated worldwide.

“Shell wants to become a leading supplier of green hydrogen for industrial and transport customers in Germany,” he added. “We will be involved in the whole process — from power generation, using offshore wind, to hydrogen production and distribution across sectors. We want to be the partner of choice for our customers as we help them decarbonize.”

Shell has a target to become a net-zero-emissions energy business by 2050, in step with society. As part of its Powering Progress strategy, Shell plans to transform its refinery footprint to five core energy and chemicals parks. This means Shell will reduce the production of traditional fuels by 55 % by 2030.

The Rheinland electrolyzer will use renewable electricity to produce up to 1,300 tons of green hydrogen a year. This will initially be used to produce fuels with lower carbon intensity. The green hydrogen will also be used to help decarbonize other industries. The European consortium backing the project consists of Shell, ITM Power, research organization Sintef, consultants Sphera and Element Energy. The electrolyzer was manufactured by ITM power in Sheffield, UK, and includes parts made in Italy, Sweden, Spain and Germany.

Armin Laschet, North Rhine-Westphalia’s Minister-President, said: "We are a hydrogen region. With the commissioning of the largest PEM electrolysis plant in Europe, we are further expanding our leading role in this field. We are therefore laying the foundation for a modern and green industry, with highly skilled jobs. Today, 30 % of German demand for hydrogen already comes from North Rhine-Westphalia's industry. Estimates predict that demand will double by 2030. This is why we need innovative solutions that will meet the demand for CO₂-neutral hydrogen. Projects such as Refhyne demonstrate how innovation can benefit both the environment and the economy."

Bart Biebuyck, Executive Director of FCH JU, said: "In order to achieve climate neutrality by 2050, we need to fundamentally reshape our energy system. Clean hydrogen will play a key role in e-mobility and in industry, as it has great potential for decarbonizing sectors where direct use of renewable energy is not possible. Accordingly, we want to accelerate the market launch of fuel cells and hydrogen technology and tap into their advantages in Europe.”
