Gothenburg solves its energy challenges with a combination of previous initiatives and new technology. In Gothenburg, 90 percent of the city’s apartment buildings are connected to the district heating network.
District heating was first introduced back in the 1950s, today, the city has one of the most well-developed district heating systems in the world and are working with innovative energy solutions for the future energy system. By combining earlier initiatives with new technologies, Gothenburg meets its challenges in the energy area.
Gothenburg’s district heating network is today almost 760 miles long. Best practice solutions have been developed to maximize the utilization of primary and secondary energy resources. This means reduced operational costs and carbon emissions, as well as increased energy efficiency. Approximately 80% of the hot water is surplus heat.
Gothenburg’s municipally owned energy company aims to be fossil free by 2025. A few examples of the measures being implemented by Göteborg Energi:
New technology for fossil free heat and power station: The Rya station produces both district heating and electricity. The site has an important role in Gothenburg’s energy supply. By 2025 at the latest, the ambition is that all district heating in Gothenburg is produced by renewable or recycled energy sources.
Accumulation tanks for storing heat: With the help of an accumulation tank, energy can be stored that would have otherwise been wasted. The tank works like a thermos and when demand for heating is lower, heat is stored in the tank. The heat is then used when demand is higher, which means that fossil-based heating stations are not needed to the same extent.
