Hymspiel

The holistic transformation of the energy system is associated with challenges, including fluctuating electricity generation from renewable energy sources such as wind and solar. This requires new concepts for the local energy supply of buildings and districts, which are characterized by more flexibility and decentralization with regard to the balancing of energy generation, storage and consumption.

In the X-Energy project Hymspiel, an integrated concept for local energy generation, storage and supply is being developed and tested in a real environment. To this end, a hydrogen production plant with storage as well as reconversion and waste heat utilization for the efficient integration of renewable energies into the supply of several buildings at the Energy Campus in Hamburg-Bergedorf is to be developed, constructed and researched.

This new and innovative approach uses a model at system level to examine both the operating behavior of the system technology to be tested in practice and its interaction - including with existing systems such as a wind farm, heat pumps, PV systems and electric cars. Among other things, answers are to be found for the supply-flexible storage and demand-oriented reconversion of renewable energies into and from hydrogen to improve the local energy supply in the neighborhood context. The question of how buildings can also supply each other and benefit from each other ("prosumer approach") will also be investigated. A feasibility study will then bundle promising system configurations and findings and enable them to be transferred into practice, particularly in the Hamburg metropolitan region.

As a result, the applied research of CC4E and HAW Hamburg will be strengthened and new (research) infrastructure will be implemented, which can also be used for further research projects. The project is integrated into the development of the Sector Coupling Demonstration Center at the Energy Campus and will also be used to make the energy transition tangible on site.
