Five companies in Zealand want to make green fuels cheaper

16. January 2023

In a new project, five companies in Zealand will develop technologies that, with a focus on side streams and CO2, can make the production of hydrogen and green fuels cheaper. This happens, among other things, with the construction of an electrolysis plant at Kalundborg Utility.

Production of green hydrogen from renewable energy sources – so-called Power-to-X – must be scaled up and down in price, and the opportunities to find large amounts of water and green CO2 sources for the purpose.

In short, this is the goal of the new project PtX Cluster Zealand, where five high-tech companies from Zealand collaborate on technology development that can help reduce the cost of Power-to-X production by up to 20 percent. This is done in close interaction with researchers, industry and business support actors.

The project consists of eight main activities, all of which deal with the main and side streams for Power-to-X production, which is a green, emerging business area.

Full speed ahead

One of the participating companies is Dynelectro from Viby, who in PtX Cluster Zealand will build an electrolysis unit at Kalundborg Utility. So says Søren Højgaard Jensen, CEO of Dynelectro.

“We will build a container-based prototype with a capacity of up to 100 kW, which is an important step towards the final commercialization of our technology. The global goal for the production of green hydrogen is huge towards 2050 – the market is almost inexhaustible – so for us it is about pushing the pedal down now for the benefit of our business and the climate,” says Søren Højgaard Jensen.

According to him, the global market for the production of green hydrogen will have a total value of 630 billion euros by 2050.

50 years of experience

Part of the PtX Cluster Zealand project is about investigating the coupling of the new Power-to-X technologies to the existing Kalundborg Symbiosis, where industrial companies have collaborated for many years to share resources such as energy, water and residual materials.

“In Kalundborg, we have been working with green symbiosis across sectors for over 50 years. We are building on that experience now. An example of this is, for example, our biotech industry, which can utilize the oxygen from the electrolysis used for the production of the green hydrogen. Power-to-X can become a new, climate technology growth adventure on Zealand, which we are proud to support”, says Christian Beenfeldt, Project Director in Knowledge Hub Zealand, which is one of the project-leading organizations in PtX Cluster Zealand together with Energy Cluster Denmark and Erhvervshus Sjælland.

“Our task is, among other things, to help companies on their way to a new market. There is not a large market for hydrogen in Denmark or abroad yet – but it will come soon. We are treading new ground, but in Region Zealand we have a good starting point for creating a common success that can create growth and jobs in our small and medium-sized enterprises while benefiting the green transition,” says Thomas Østergaard Jørgensen, business developer at Erhvervshus Sjælland.


PtX Cluster Zealand is supported by the Danish Business Promotion Board with DKK 24.5 million from the REACT-EU programme and runs until August 2023. The project includes the Zealand companies Dynelectro, Unibio, Nordphos, Algiecel and G2B. In addition, several utilities, Ørsted, Evida, Kalundborg Forsyning A/S, DTU, Gas Storage Denmark, Knowledge Hub Zealand, Energy Cluster Denmark and Erhvervshus Sjælland participate.
