REFHYNE II

REFHYNE II is the continuation of the successful REFHYNE I project and is funded by the EU's Horizon 2020 research and innovation programme. Building on the experience gained with the 10-megawatt plant from REFHYNE I, ITM Power has developed a new design for a 100-megawatt plant using polymer electrolyte membrane (PEM) technology (see REFHYNE I project). The capacity expansion is to be implemented as part of REFHYNE II, for which the final investment decision was made in July 2024. From 2027, the plant will produce up to 15,000 tonnes of hydrogen per year, making it one of the largest plants of its kind in the world.  

The high-purity hydrogen produced will be used primarily for the partial decarbonisation of the Wesseling refinery site. The renewable hydrogen will be used to produce low-carbon fuels that meet the European Union's requirements for renewable fuels of non-biogenic origin. In the medium term, an expansion of renewable hydrogen production for regional industrial companies is also conceivable, provided there is sufficient demand.
