Grüner Wasserstoff aus erneuerbaren Energien soll künftig fossile Energieträger in bestimmten Anwendungen in der Industrie und im Verkehr ersetzen, die nicht direkt elektrifizierbar sind. Laut Nationaler Wasserstoffstrategie soll ein Teil des künftigen Wasserstoffbedarfs inländisch durch Elektrolyse mit erneuerbarem Strom erzeugt werden. In dieser Studie wird mit einem Stromsektormodell untersucht, ...
Heat pumps are a key technology for reducing fossil fuel use in the heating sector. A transition to heat pumps implies an increase in electricity demand, especially in cold winter months. Using an open-source power sector model, we examine the power sector impacts of a massive expansion of decentralized heat pumps in Germany in 2030, combined with buffer heat storage of different sizes. Assuming that ...
To phase out fossil fuels, energy systems must shift to renewable electricity as the main source of primary energy. In this paper, we analyze how electrification can support the integration of fluctuating renewables, like wind and PV, and mitigate the need for storage and thermal backup plants. Using a cost-minimizing model for system planning, we find substantial benefits of electricity demand in ...
Conventional wastewater treatment plants consume significant amounts of electricity. The constant aeration of the wastewater in order to foster the growth of microorganisms or the pumping of wastewater are two examples for energy-intensive processes within a plant. Case studies have shown that switching off blowers and inlet pumps for a certain period of time is possible without a loss in water quality. ...
