Reußenköge, 20 May 2020
The EEG (Renewable Energy Sources Act) subsidy no longer applies - how can solar and wind power continue to be used profitably? Today is the ground-breaking ceremony for a concept that is unique in Germany and shows how this works in two ways: Bosbüll Energie GmbH is building a district heating network that supplies heat exclusively using regional electricity from wind energy and photovoltaic plants whose subsidies are being phased out. In addition, the waste heat generated during the production of green hydrogen is used for the heating network. And the added value remains on site: From the end of this year, 25 residential buildings and a large pigsty in the municipality of Bosbüll will be heated with over 1,100 MWhth, with further buildings to follow. The initiators of this innovative project are Ove Petersen, founder and managing director of GP JOULE, Reußenköge, John-Heinrich Ingwersen, managing director of Windpark Bosbüll GmbH & Co. KG, as well as Ingo Böhm, managing director of Bosbüll Energie GmbH and mayor. The commercial and technical management is handled by the experts of the GP JOULE Group.
Promising sector coupling
The heating network system will be linked to the ground-breaking hydrogen mobility concept eFarm (power-to-gas), which is currently being built in Bosbüll. For heat generation, Bosbüll Energie GmbH is investing in an air heat pump and a heating element (power-to-heat). In addition, the waste heat from the electrolyzers, which is generated during the production of hydrogen from the green electricity, flows into the district heating network. Thus, wind energy and PV plants will continue to be used for heat generation and electrolyzers even after the end of the EEG term. In order to generate heat that is as resource-saving as possible, electricity is to be preferably used according to the “Eisman” timing schedule.
Joint ground-breaking ceremony
The starting point of the heating network is the central heating plant, right next to the eFarm and the large customer pigsty. A 2,680 m long distribution network, including house connections, will distribute the heat to the initial 25 customers in Bosbüll. In addition to the investment by the shareholders of Bosbüll Energie GmbH, the ecological project is also supported by the subsidy programme Wärmenetzsysteme 4.0 (heat network systems) of the Federal Office of Economics and Implementation Control (BAFA).
