Power-to-X means using renewable electricity, for example wind power, to create something else (‘X’). The ‘X’ created is an energy carrier – usually renewable hydrogen – which can power medium- to heavy-duty transport or be used in industry.
Renewable hydrogen, or green hydrogen, can in turn be synthesised into other green fuels, such as e-methanol for shipping, e-kerosene for aviation, and e-ammonia for industrial use in fertilisers or as a shipping fuel. We also call these electro-fuels, or e-fuels.
The scientific process used to create green hydrogen is electrolysis. In other words, green electricity is used to split water into hydrogen and oxygen.
One third of global carbon emissions come from industry and heavy transport. While we have the science for producing green hydrogen and green fuels to decarbonise these sectors, the challenge is to:
- combine and scale the solutions
- make them cost-competitive
- make them work in unison with fluctuating renewable energy production.
At Ørsted, we like a challenge. We’ve set our sights on creating a world that runs entirely on green energy, after all. Using our experience as the global leader in offshore wind, we’re moving full speed ahead to accelerate deployment of Power-to-X.
We have projects underway in Europe and the US. By 2025, our FlagshipONE facility in Sweden will start producing 50,000 tonnes of e-methanol every year – green fuel that will enable vessels to sail carbon-free.

Helps meet climate targets
Renewable hydrogen offers a zero-emission alternative to fossil fuels. Deploying it can make a significant contribution to countries’ climate targets.
Can be produced locally
It only takes water and green electricity to produce renewable hydrogen. In each market where we develop a Power-to-X project, we focus on sourcing renewable power locally, whether it’s from offshore wind, onshore wind, or solar PV.
Has many immediate uses
Green hydrogen can replace all uses of fossil-based hydrogen in heavy industry and be applied in new areas of industry. It can also be used in fuel cells in medium- to heavy-duty transport, and in the air and maritime sectors via synthesis to green fuels.
Ørsted's Power-to-X projects
In order to truly scale Power-to-X technology and make it cost-competitive at the speed that’s needed to decarbonise society, we need partners. That’s why we’re working with leading demand partners, industry partners, and regulatory partners to develop large-scale production of green fuels.
