Solar thermal energy

Integrating solar heating in a district heating system to produce hot water

Solar thermal energy or solar heating is an integrated part of the Danish district heating system and more than 40 large-scale plants around Denmark produce hot water from the sun’s energy. In 2017, solar heating covered 2 percent of the Danish district heating production, but the technology could potentially contribute with up to 10 percent by 2030. The technology plays well with other energy sources (CHP plants, gas-fired boilers, heat pumps etc.) in a district heating system. In many cases, solar heating is also combined with a seasonal storage pit filled with heated water. Here, energy from hot summers can be stored for cold winters.
