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.
We invite you to explore solar thermal energy related solutions in more depth below, find potential partners, catch up on the latest solar thermal energy news and discover real-life case examples of how solar thermal energy can help solve your energy issues.
District Energy holds a vast potential for energy efficiency in urban areas. This White Paper highlights the key elements for success in district heating and cooling.

With a PPA, Chr. Hansen and Better Energy take responsibility for adding entirely new renewable energy to the Danish electricity system. Energi Danmark’s role will be to balance both the consumer and the producer as well as manage price risks and ensure Chr. Hansen’s desire to create a green balance with their consumption.
Aalborg CSP landed an order to deliver a 2.6 MWth solar-thermal plant in Denmark. With the system in Egedal, Aalborg CSP continues its series of new projects based on customized solutions with solar and storage supporting a competitive transition to renewable energy.
Aalborg CSP has received the largest order in terms of megawatt power to deliver steam generator systems based on the leakage-free header-and-coil technology for three CSP plants in Dubai, each providing 200 MWe totalling 600 MWe for the largest CSP project in the world. When completed, the solar park will provide clean energy to more than 270,000 residences in Dubai, while reducing the carbon emissions by 1.4 million tonnes per year.
Danish power plants are among the most flexible in the world, assisting the integration of large shares of wind in the Danish power system. The Danish power plant experiences are shared with China in a collaboration that aims to minimise the significant waste of wind and solar power in China today. The Danish and Chinese experiences were shared at a power plant flexibility event, which took place in Copenhagen on 24 May in connection with the ninth Clean Energy Ministerial (CEM) and Nordic Clean Energy Week.
Renewables have experienced a remarkable evolution over the past decade. Indisputably, they now form the leading edge – in combination with energy efficiency – of a far-reaching global energy transition. Spurred by innovation, increased competition, and policy support in a growing number of countries, renewable energy technologies have achieved massive technological advances and sharp cost reductions in recent years.
A new resource and energy plant is to contribute to a greener Hamburg. The plant will be the city’s new green energy symbol and it marks the change from traditional waste incineration to an integrated use of energy resources in the waste.
In the years leading up to 2035, the amount of wind and solar power in the Northern European energy system will grow to the extent that new energy plants which can convert electricity into other energy products will become cost-effective, especially in Denmark.
While renewable electricity has attracted significant political attention in countries around the world, renewable heat “remains the sleeping giant of energy policy”, writes the International Energy Agency (IEA). Renewable heat represents a massive opportunity for emissions reductions, as heat consumption accounts for over 50% of total final consumption.
Two years ago, it was hard to believe when the Danish electrical grid managed an entire day without support from centralised power plants to stabilise it. In 2017, the grid easily managed without for a whole week.
Flat solar-thermal collectors matching the client’s energy needs Aalborg CSP received an order from the combined heat and power plant Smørum Kraftvarmeværk A.m.b.A. to deliver an 8MWth solar heating plant that will reduce the facility’s natural gas dependency as well as stabilize energy prices. The 11,312 m2 solar field, which is located in the town of Smørum, […]
If we are to succeed with the transition from fossil fuels to renewable energy, there is a need for more flexibility in the energy system. In the project ”Storage of electricity and heat in salt hydrate”, we demonstrate and test the prototype of a new heat battery that is able to store solar energy and […]
Heliac’s solution is based on the invention of an inexpensive lens that focuses the sunlight in the same way as a large magnifying glass. Based on the lens, Heliac builds modular panels each supplying 12 kW of heat. Lendemarke Fjernvarmeværk, owned by Europe’s largest privately owned energy company, E.ON., is the first customer of a […]
