Orsted has teamed up with a chemical group to build a major electrolyser facility, in one of the most ambitious attempts yet to tap green hydrogen from offshore wind.

The Danish group and Yara, a global fertiliser producer, will seek public funding to co-develop a 100MW electrolyser in the Netherlands, generating H2 for use at Yara’s Sluiskil facility in Zeeland using power from Orsted offshore wind farms.

The planned electrolyser would provide enough hydrogen to produce about 75,000 tonnes of ammonia a year, replacing current fossil-based production equivalent to 10% of output at one of Sluiskil's plants.
