Heat for 1300 Households from Denmark's First PtX Agreement

TVIS and Everfuel succeed Denmark’s first agreement of surplus heat from a PtX facility. Everfuel invests in a 4.5 MW heat pump to cool the supporting processes in the hydrogen production. TVIS, the local district heating network, is building a 1.2 kilometre long transmission line to Everfuel's 20 MW electrolysis plant, HySynergy. When TVIS and Everfuel signed the first agreement six months ago the volume corresponded to the consumption in 5-600 households per year. The new agreement increases the volume to about three times as much, as the volume of heat correlates to the annual consumption of approximately 1300 households.

“In December 2021, we signed Denmark's first agreement on surplus heating from hydrogen and PtX technology in Fredericia, and now we are increasing the amount of heat approximately three times. We attain valuable experience about the heat potential of PtX technology, but we also streamline operational time of the hydrogen plant and utilise valuable amounts of energy that would otherwise disappear into thin air. We are making history not only in TVIS but also in the district heating world by utilising surplus heating from hydrogen production and helping to ensure a stable district heating system on the short and long term,” says Lars Schmidt, Chairman of the Board of TVIS.

“The utilisation of surplus heating is an important part of our technological development and understanding of the potential in utilising local heat transmission as a cooling resource for our processes. With the agreement the site's efficiency will be of the highest standard with plant efficiency of approximately 87%. It gives us important experience ahead of Phase II, which consists of an expansion of the electrolysis plant to 300 MW in 2025,” says CEO Jacob Krogsgaard from Everfuel.

“When we have completed our new transmission pipeline, the heat will be circulated across four municipalities and reach about 60.000 households, apartment buildings, institutions, and companies. And there are many more consumers in sight. This is why we value important agreements like these with Everfuel, because the four municipalities behind TVIS are experiencing high settlement growth and business development and have ambitious strategies for phasing out gas and oil. District heating plays a key role, and our collaboration are prime examples of sector coupling that shows the path to the energy system of the future, where the surplus of one company is the resources of another,” says Jørgen Nielsen, CEO of TVIS.
