Denmark will postpone the roll-out of a green hydrogen transmission pipeline between western Denmark and northern Germany by three years to 2031 from 2028, the country's energy ministry said on Tuesday.

Denmark has worked with transmission system operator Energinet to make the timeline more reliable and to limit delays, Energy Minister Lars Aagaard said in a statement.

"This is to ensure interaction between the large amounts of green power from the offshore wind supply, the production of green hydrogen and German demand," Aagaard said.

Work on the transnational pipeline is ongoing in cooperation with the German government, Denmark's energy ministry said.
