The world's largest hydrogen electrolysis plant with a capacity of 100 megawatts is to be built in the port of Hamburg. The talks with potential customers and investors are already well advanced, and the final decision on the construction of the plant is to be made before the end of this year, Michael Westhagemann, economics minister in the city state of Hamburg, told dpa. The construction of the plant will cost a three-digit million sum and will be made possible by subsidies from the federal government and the EU. Hamburg will provide the necessary space.
The minister's initiative was prompted by Germany’s energy transition and climate policy, which is negatively impacted by a lack of storage facilities for electricity. In the northern German federal states, but also in the Netherlands, voters and initiatives are increasingly in favor of hydrogen as an essential source of energy in the future. A joint hydrogen strategy for the northern states is in the works, as well as at the federal level. The hydrogen is to be produced regeneratively with offshore wind power at sea or on land and then stored in cavern storage facilities or used directly. This would enable the quantities of electricity generated on the North Sea to be used more effectively.
A 100-megawatt electrolysis for the production of hydrogen would represent a new technical dimension. The largest plants to date have a capacity of 10 megawatts at most.
