Wind Denmark said Power-to-X (PtX) is an important element of the country's ambition to reduce carbon emissions by 70% compared to 1990 by 2030.
The PtX Alliance will "contribute to the dissemination of Power-to-X in Denmark, and to break down regulatory barriers".
"The cooperation is to ensure that large-scale production of, for example, hydrogen, as well as secure opportunities for a new export adventure of both green fuels and technology for production," Wind Denmark said in a statement.
An official launch of the alliance for members of either association is scheduled to take place on 5 May.
The alliance will aim to establish a "strategic direction" for connecting wind turbines to electrolysis equipment, to promote innovation and testing of PtX "especially hydrogen, methanol and ammonia", and support export of "Danish PtX solutions".
"The establishment of the PtX Alliance must be seen in light of the fact that we have only scraped the surface in relation to the potential for using electricity to produce green fuels," said Jan Hylleberg, CEO of Wind Denmark.
"If we in Denmark are to become leaders in this field, and help the green transition here at home and create a new export adventure, then we must rethink our legislation, which will be the main purpose of the PtX Alliance," he added.
Meanwhile, Tejs Laustsen Jensen, director of Hydrogen Denmark said the demand for hydrogen and other fuels made from electrolysis will "explode" in the next decade.
He said it was important the Danish industry moves now to "seize the opportunities to become a leader" in PtX.
