As a result of the increased Danish ambitions within Power-to-X, the partnership behind the Power-to-X flagship project 'Green Fuels for Denmark' in Copenhagen has decided to bring forward parts of the project in order to produce green fuels for heavy transport two years earlier than previously planned. Specifically, the partnership has decided to bring forward 100 MW of the originally planned second phase’s 250 MW electrolysis from 2027 to 2025, as well as to begin capturing sustainable carbon dioxide in 2025.‘Green Fuels for Denmark’ can potentially supply green fuels corresponding to Denmark's total domestic consumption of jet fuel by 2027 when the full second phase is commissioned, thus fulfilling the government's ambition of 100 % green domestic aviation by 2030, three years ahead of schedule.The accelerated phase of 100 MW can produce more than 50,000 tonnes of sustainable fuels in 2025, mainly e-methanol for shipping, but prompted by the Danish Government's ambition to establish green aviation opportunities in Denmark as early as 2025, the partnership will examine whether parts of ‘Green Fuels for Denmark’s’ expected production of green aviation fuels can also be brought forward to 2025.However, the fulfilment of the Danish 2025 ambition, as well as the 2030 ambition requires the establishment of a regulatory framework that makes green jet fuel a real and competitive alternative to fossil fuels. Chemically, there are several ways to produce aviation fuels from hydrogen and sustainable carbon dioxide, and the partnership will explore the various technological possibilities.In the initial vision for ‘Green Fuels for Denmark’, the plan was to commission an electrolysis plant with a capacity of approx. 10 MW in 2023 and subsequently 250 MW in 2027 and 1,300 MW by 2030. It’s still the partnership’s plan to expand the full second phase of Green Fuels for Denmark to 250 MW by 2027. This phase will be able to supply enough jet fuel to cover significantly more than the expected Danish domestic consumption of jet fuel and thus also contribute to the conversion of international aviation from Denmark, provided that the necessary framework is established. At the same time, the realisation of the full second phase depends on the availability of sufficient amounts of new green power, e.g. from offshore wind.Green Fuels for Denmark's final phase of 1,300 MW will be able to supply green fuels, primarily jet fuel, that can replace approx. 30 % of the total fuel consumption at Copenhagen Airport, which will entail a significant green conversion of international air traffic in addition to domestic air travel.Currently, there’s no significant consumption of sustainable aviation fuel produced through Power-to-X, either in Denmark or internationally. Therefore, Denmark has a unique opportunity to create an international leadership position, but the technology for producing the fuels still needs to be matured significantly, just as new aviation fuels must go through a thorough and extensive approval process before they can be used in aviation.
