Energy and Power to X

The Triangle Region shall be a European hub for green fuels

Power-to-X is the process where green electricity is converted into hydrogen – and thereafter can be further processed into, for example, liquid green fuels, but also fertilizer, plastic, textiles, and much more in our everyday life requires carbon and hydrogen.

The Triangle Region is part of the partnership Triangle Energy Alliance, which is an inter-municipal collaboration in the Triangle Region between municipalities, educational institutions, large-scale energy producers, and infrastructure owners. The focal point is the construction of Power-to-X facilities on an industrial scale because the Triangle Region has very advantageous infrastructures and already well-established cooperation on regional development.

First phase adopted by Danish Hydrogen Backbone

At the beginning of 2025, the Danish Parliament decided to establish the first phase of the hydrogen pipeline infrastructure, which runs from Esbjerg via Vejen to the Danish-German border (the 7-shape). The Triangle Region Denmark is pleased that the project with green hydrogen is now becoming a reality but will work to ensure that phase 2 (pipeline to Fredericia) is realized as soon as possible.

A hydrogen pipeline from Esbjerg via Vejen to Fredericia and down to the Danish-German border (the so-called lower T) will benefit all of Denmark – not just local companies. It will strengthen the green transition, secure energy supply, and create new opportunities for green industry.

A shortcut to climate goals

Hydrogen can be used to reduce CO2 emissions, e.g., by replacing fossil hydrogen in refineries with green hydrogen. Additionally, greener fuels for transport, such as trucks and airplanes, can help us reach climate targets.

With a hydrogen pipeline, Denmark can also export green energy to Northern Europe's heavy petrochemical industries and help develop future sustainable fuels and everyday products.

Power to X – The fuel of the future

As the world looks at new ways to handle climate challenges, Power to X (PtX) has become one of the most promising technological breakthroughs. But what exactly is Power to X, and how does it work? In this article, we dive into the technology behind PtX, how hydrogen plays a central role, and why Power to X can become a gamechanger for the green transition in Southern Jutland and the rest of Denmark.

What is Power to X?

Power to X is a technology that makes it possible to convert electricity (often from renewable energy sources such as wind and solar) into other forms of energy, fuels, or chemicals. This means that excess green energy can be stored and used in a way that is not directly dependent on the power grid.

Hydrogen Power to X is one of the most prominent applications of PtX technology. Here, electricity is used to produce green hydrogen via electrolysis – a process where water is split into oxygen and hydrogen. The green hydrogen can then be used as fuel, stored for later use, or applied in industry, the transport sector, or energy storage.

How does Power to X work?

PtX technology is based on converting electricity into something that can be used later. The most well-known method is electrolysis, where electricity is used to separate water (H₂O) into hydrogen (H₂) and oxygen (O₂). When the produced hydrogen is "green," it means the process is powered by renewable energy, which does not produce CO₂ emissions.

This hydrogen can be used in several ways:

Green hydrogen can be used as fuel in the transport sector – e.g., in hydrogen cars or trucks.
The hydrogen can also be converted into synthetic fuels, such as green fuels for planes or ships.
It can be stored and used as a way to balance the power grid when, for example, solar and wind power production is unstable.

Hydrogen Power to X

One of the most exciting aspects of Power to X is its potential to transform both industry and the transport sector. Green hydrogen can replace fossil fuels in processes that are difficult to electrify.

Instead of using fossil oil and gas, green hydrogen from Power to X hydrogen can be used for the production of everything from steel to chemicals and even as fuel in hydrogen-powered vehicles, both on land and at sea. This will be a decisive step towards reducing CO₂ emissions in sectors that are difficult to electrify directly.

What does Power to X mean for Denmark?

Power to X companies have great growth potential in the upcoming green transition. The technology can provide companies in both heavy industry and the transport sector access to renewable energy in the form of hydrogen or synthetic fuels.

For investors, this means that Power to X is an area with great potential for long-term gains. Green fuels are a future key component in the global energy market, and those who invest in technology and infrastructure today will be well-positioned in the future.

Power to X - A greener future

Power to X is not just a technology – it is a solution to some of the most pressing challenges in our green transition. Green electricity is a necessary prerequisite for a climate-neutral society, but we cannot settle for electricity alone. From hydrogen production and green fuels to industrial applications and the transport sector, PtX will play a decisive role in shaping the energy of the future.

For companies, investors, and local communities alike, it is an opportunity to create a sustainable, future-oriented energy transition. This means more than just technological advances – it means new jobs, business opportunities, and a more sustainable future for us all.

PtX and hydrogen cluster in the Triangle Region

In the Triangle Region — with Everfuel and Crossbridge Energy in Fredericia at the center — the transition to green hydrogen is already concrete:

Everfuel inaugurated in 2025 the HySynergy plant in Fredericia: a 20 MW electrolysis plant for the production of certified green (RFNBO) hydrogen, which is one of Europe's largest and supplies hydrogen to Crossbridge Energy’s refinery in Fredericia, located right next door.
The refinery in Fredericia produces all of Western Denmark's fuel consumption – including all of Billund Airport and Skrydstrup Airforce. The plant uses large amounts of hydrogen in production — and the collaboration shows that fossil hydrogen can be replaced by green hydrogen on an industrial scale.
The inauguration of HySynergy also marked Denmark's first export of green hydrogen: a trailer filled with hydrogen, which was sent to Germany, where it is used for buses.

This means that the Triangle Region — with Fredericia as the focal point — has actually moved out of the planning phase and stands with an active, industrial green hydrogen production and collaboration, where surplus heat is utilized in the local district heating system and improves the operation and business model for the end product. The combination of existing refinery and energy infrastructure, a new electrolysis plant, and deliveries of green hydrogen to industry makes the area a concrete center for PtX and sector coupling in the middle of Denmark.
