Phase II consists of a plant expansion to 300 MW in 2025, in three expansion phases of 100 MW, each with an expected ex- cess heat resource of 50.000 MWh. It is one of several collaborations that improve the financial benefits of both sectors end products. Danish technical advi- sory company COWI estimates that using surplus heat from PtX-technologies can reduce hydrogen prices by 5-10 percent, thus making the hydrogen plant more competitive. “The next step might be 1 GW hydrogen production facili- ties, but finding capacity in the existing heat infrastructure, power grid and supplying it with enough green carbon di- oxide is a real challenge. Maybe in the future combined heat and power plants, CHP’s, could convert to – CHPC’s - Combined Heat, Power, and Carbon-plants, if you will“, says Jørgen Nielsen. Ideal regional infrastructure At the regional airport, Billund Airport, approximately 100.000 tons of kerosene is fueled annually, which equals 10% of the total jet fuel consumption in Danish airports before Covid19. “Same volume is necessary in the case of e-kerosene, which re- quires 535.000 tons of carbon dioxide in the chemical process. Local waste, power, and heat plants, biogas plants, and the Re- finery also have available sources of surplus carbon that can
posed from fossil fuel refinement. Today the Refinery is supply- ing a third of the Danish oil product demand into a chemical plant, producing carbon-based sustainable, synthetic fuels and chemicals. Soon, large amounts of wind power from the North Sea energy island and land-based solar and wind energy sourc- es are being built. These can be transmitted to Fredericia for green fuel production and storage, for which local partners are preparing the production facilities and infrastructures. A sustainable neighborship requires good chemistry Everfuel is building a 20 MW hydrogen production plant in Phase 1 next to the Crossbridge Energy Refinery, which will be in production in late 2022. They will supply the Refinery with hydrogen for fuel production through electrolysis, which is currently utilized in the existing refining processes. One ton of hydrogen based on sustainable sources, such as wind or solar power, will reduce carbon dioxide emissions by 10 tons – com- pared to hydrogen produced with fossil sources. In Phase I, the heat from the hydrogen plant in Fredericia will cover the annual heat consumption in 1.500-1.800 average Danish households. Of equal value or even more are the prac- tical experiences gained on the heat potential of PtX-technol- ogies, which are valuable for short- and long-term heat supply strategies. Heat utilization will increase the operational hours of the hydrogen plant because the district heating water is used to cool the technical facilities.
