Storing power and heat in the district
Sustainable energy provision is to be developed for the urban district of Rüsdorfer Kamp in Heide. The QUARREE100 research project is investigating how the district could be fully supplied with local or regional renewable energy sources. One goal is to integrate the regionally generated wind power into the regional energy system in an economically efficient and system-serving way.
Power, heat and mobility are to be intelligently networked in everyday life, and renewable energies should be sensibly integrated into existing supply grids. Over the next five years, scientists and planners in the Quarree100 research project will develop the technologies required to use and test them in the Rüsdorfer Kamp district. The project partners are investigating both technically mature as well as novel options for sector coupling and energy storage.
The energy systems must be resilient, i.e. robust, in order to guarantee supply even in extreme situations and during fault events. At the same time, the district ought to stabilise the regional energy supply system. The solutions developed should be transferable to other cities.
Initial situation: Regional wind power surplus
The expansion of wind energy in Schleswig-Holstein has accelerated significantly in the course of the energy transition. In the vicinity of the city of Heide, there are numerous wind turbines that are partially owned by citizens. There is an increasing oversupply of wind power. In Heide, the aim is to make greater use of these surpluses in the future in order to avoid throttling wind turbines and limit the costs of the energy transition.
The regionally generated wind energy is to be used in the energy supply system in an economically efficient and system-serving way. The surplus wind energy supplies power for households and mobility or is used to produce hydrogen, and is therefore available as an energy source – for example during low wind periods.
Rüsdorfer Kamp district
The 20-hectare urban district in Heide is mostly comprised of residential buildings built in the 1950s to the 1960s. Natural gas is available throughout the area. Around 60 per cent of the buildings are connected to the grid and use gas for their heating. The other buildings use mostly oil-fired heating systems. The location close to the city’s centre and existing open spaces offer good conditions for a cautious further development of the district. The focus is on the implementation of an own energy generation and supply system that takes into account both centralised and decentralised renewable energy sources. Electricity storage, electromobility and heat generation are to be realised with surplus wind power. It is planned to store further surplus electricity in gas reservoirs by way of electrochemical conversion.
The Solar Construction / Energy-Efficient City support initiative
The project is being funded as part of the Solar Construction/Energy-Efficient City support initiative set up by the German Federal Ministry for Economic Affairs and Energy and the German Federal Ministry of Education and Research. Module 2, “Energy-efficient city”, focuses on districts that utilise innovative ideas to combine energy efficiency and renewables.
