The hydrogen Competence Centre H2Herten is disposing over a special power and hydrogen supply concept, which relies heavily on renewable energies. An important role takes the wind power plant at the site, because it is able to supply the competence centre with electricity as well as producing power for emission free hydrogen production. The produced hydrogen should be implemented in the hydrogen supply system of the centre. Moreover it should supply the planned hydrogen filling station.
The combination of the existing wind power plant with a complementary energy system on the basis of hydrogen is a central element in the energy concept. The system is able to store a part of the free emission produced energy in the form of electrolytic produced hydrogen. If the direct renewable energy supply is insufficient or short peak loads must be covered, the hydrogen will be transformed in electricity with the help of a combustion engine. After that it will be injected in the grid. The operators of the centre expect an energy demand of 200.000 kWh each year. Through the combination of the wind power plant and the hydrogen energy system the energy demand will be covered with high quality and emission free power.
Energy complementary system including periphery
Process engineering starting point is the power feed of the wind power plants Hoppenbruch which is located close to the centre. It covers the energy demand of the energy complementary system. Besides using the hydrogen to cover standard and reserve power the hydrogen should also be used for hydrogen vehicles. The performance of the electrolyzer, provided by Evonik, is constructed to supply the near filling station with the produced wind electricity surplus. The production and the reconversion of hydrogen are not lossless. In both processes electric current and hydrogen will be converted into heat in quite a large amount. To minimize the losses and maximize the overall impact, the usage of waste heat of the operating system to supply the user centre is intended. For the optimal coordination of the power flows and the energy storages, regarding efficiency and durability, the use of an energy management system is planned in medium term. Last but not least the development and optimization of the energy management system is a main goal of the plant operation.
