"The Heide oil refinery has opted to use green hydrogen. However, the electrolysis plant project “Westküste 100” was cancelled early three years after the project started. The Heide refinery, Ã...rsted Germany and Hynamics Deutschland have announced that they will not build an electrolyser. More than three years ago, they joined forces as "H2 West Coast GmbH" to produce green hydrogen on the premises of industrial operations in Hemmingstedt. The main reason for the decision against the 30-megawatt plant is the high construction costs, according to the companies in a press release (NDR: 17.11.23)."
