Vrejlev Bioenergy, points out that it is a trust-based agreement between his company and the Vraa Varmevaerk - it is a win- win for both Vrejlev Bioenergy and Vraa Varmevaerk. The district heating consumers get cheaper locally produced heat, and Vrejlev Bioenergy gets local goodwill. As CEO Thomas Kjær says, "We live here and give back to the local community as a “thank you” for being allowed to fill the landscape with our plant and many lorry transports". If CEO Thomas Kjær looks into the future, he wishes, like the mayor, to have established a district heating transmission grid between several heating plants. So that he can supply excess heat all year round and not have to spend money on cooling in the summer. At the same time, he sees opportunities to deliver far more excess heat from various sources in his company. For example, the amount of excess heat could be increased by cooling the slurry before it is brought out to the field if a heat pump is connected.
of using an external heat supplier is that the supplier has no obligation to supply. Therefore, the supplier is responsible for investing in the district heating transmission grid. Pt. the heating plant has an application pending with the municipality for the establishment of a heat pump that must be powered by locally produced green electricity from the nearby energy park. A memorandum of understanding has been drawn up on the purchase of electricity from the future wind turbines. Vrejlev Bioenergy Vrejlev Bioenergy originated from a larger farm that established a biogas plant a few years ago. The plant has been continuously expanded and today supplies upgraded biogas to the national natural gas grid. Together with the other large biogas plants in the area, they have established a company that plans to sell biogenic CO2. The company is now being further developed with a pyrolysis plant that produces biochar from fibers, which are a residual product from biogas production. Biochar binds CO2 and can be returned to the soil, where the carbon is bound for hundreds of years. The new facility will be commissioned in April 2024. One of the residual products from biochar production is waste heat. From the beginning, surplus heat was planned for the local district heating plant “Vraa Varmevaerk.” A district heating transmission line of 2.8 km has been established, where Vrejlev Bioenergy owns the transmission pipe. Vrejlev Bioenergy owns the transmission pipe - and not Vraa Varmevaerk - because Vrejlev Bioenergy does not have an obligation to supply district heating. Therefore, it would be too risky for Vraa Varmevaerk to take the investment up front. The transmission pipe has depreciated over five years. Vrejlev Bioenergy can initially supply 1.6 – 1.7 MW/year and more in the future. The heat is distributed throughout the year. In the period from May to August, the company cools the heat away, as the district heating company covers the summer heat demand using its own solar panels. CEO Thomas Kjær,
