Engineering firm Ramboll has announced plans to build the world’s largest solar heating plant in South Jutland, Denmark, which will convert solar heat to district heating in the coming years. Still on the drawing board, the proposal seeks the development of four new plants, each measuring between 40,000 and 80,000sqm.
As of now, each of the four plants is using natural gas as fuel, which is subject to taxation. In the future, the plants will get half of all that heat from solar energy, while the remaining will come from heat pumps and natural gas. The new solution will help reduce heating bills by 15 to 20 percent, while offsetting a considerable amount of carbon dioxide.
The solar heating technique is based on the use of solar panels that use solar heat to heat up water. Heated water will then be transported to the district heating station and transformed into district heating. Since the sun isn’t shining always, the heating plants will also store somewhere around 200,000 cubic meters of hot water in reservoirs built 10 meters under the ground for later use.
