Power-to-X (P2X)

Decarbonizing American industries with green hydrogen and e-fuels


The United States has officially entered the clean hydrogen market. This growing industry is key to decarbonizing some of America’s heaviest industries, through the use of either green hydrogen or its derivative e-fuels (e.g., e-ammonia, e-methanol).

As a leading clean energy company, Ørsted is using our extensive portfolio of wind and solar assets to power P2X facilities. We’re building new green hydrogen and e-fuels projects worldwide, and supporting the development of one of America’s first clean hydrogen hubs.

What is Power-to-X?

Power-to-X (P2X) is the umbrella term for turning electricity into something else – in this case, green hydrogen. Green hydrogen is made using clean energy, such as wind and solar, to power electrolysis, a process which splits water into hydrogen and oxygen molecules, producing hydrogen without carbon emissions. Green hydrogen can be further processed into e-fuels, creating net-zero carbon molecules which can help decarbonize hard-to-electrify sectors, such as transportation, chemicals, and steelmaking.

Ørsted’s hydrogen and e-fuels projects

The green hydrogen industry is growing quickly, with P2X facilities cropping up worldwide and major companies signing commercial agreements for green hydrogen and e-fuels. Together with industry leaders in the U.S. and Europe, Ørsted is developing P2X facilities that can produce green hydrogen at scale.

Ørsted to build American hydrogen hub

The U.S. Department of Energy has selected Ørsted and six other industry partners to build the HyVelocity Gulf Coast Hydrogen Hub. This hub will leverage existing assets in Texas and Louisiana to deliver clean hydrogen to the region.

Frequently asked questions (FAQ)
  • How is green hydrogen produced?
    Green hydrogen, also called renewable hydrogen, is produced by splitting water into hydrogen and oxygen molecules using renewable electricity. The resulting hydrogen is collected and used, while the oxygen is either used, or released as a byproduct. The technology behind this splitting process, called electrolysis, is well-established, having been commercially viable and used worldwide for decades.
  • What is the benefit of using green hydrogen?
    Unlike conventional hydrogen, green hydrogen is produced without emitting any carbon emissions. This means that green hydrogen can be used to lower or eliminate the emissions footprint of current hydrogen users. It can also be adopted by hard-to-electrify sectors like shipping, aerospace, and chemicals, replacing fossil fuels.
  • Is green hydrogen safe?
    When handled correctly, renewable hydrogen is safe, being a non-toxic gas at room temperature and atmospheric pressure. Under certain conditions, hydrogen can be explosive; however, longstanding international standards exist for designing and monitoring hydrogen facilities. Many sectors have used hydrogen in their industrial processes for decades, making it a common product used in familiar applications. 10 million metric tons of hydrogen are produced in the U.S. today.
  • What are e-fuels?
    E-fuels are compounds made by combining green hydrogen with other substances to create low- or zero-carbon fuels. Green hydrogen combined with biogenic carbon can produce e-methanol or e-kerosene, while green hydrogen combined with nitrogen produces e-ammonia.
  • How do hydrogen projects benefit communities?
    Like other renewable energy solutions, green hydrogen will contribute to the development of America’s clean energy industry. This means the creation of short- and long-term jobs, a larger domestic clean energy supply chain, and investment in communities around clean hydrogen hubs. For locals, it also means a substantial reduction in pollution, as green hydrogen replaces fossil fuel use in industrial facilities.
