    Wärmepumpen statt Erdgasheizungen: Umstieg durch Ausbau der Solarenergie unterstützen

    Die verstärkte Nutzung von Wärmepumpen ist eine wichtige Maßnahme zur Senkung der CO2-Emissionen im Wärmesektor. Zudem können Wärmepumpen dazu beitragen, die Importe von Erdgas zu reduzieren. Mit Hilfe eines Stromsektormodells werden die Auswirkungen eines beschleunigten Ausbaus von Wärmepumpen auf den deutschen Stromsektor untersucht. Knapp sechs Millionen zusätzliche Wärmepumpen würden den Strombedarf ...

    Expanding Solar Energy Capacity to Power the Transition to Heat Pumps

    Increasing the use of heat pumps is an important measure for reducing carbon emissions in the heating sector as well as natural gas imports. This report uses an electricity sector model to investigate the effects of an accelerated expansion of the heat pump stock on the German electricity sector in 2030. Adding around six million heat pumps would increase electricity demand by nine percent in 2030; ...

    Power Sector Effects of Alternative Production and Storage Options for Green Hydrogen

    The use of green hydrogen can support the decarbonization of sectors which are difficult to electrify, such as industry or heavy transport. Yet, the wider power sector effects of providing green hydrogen are not well understood so far. We use an open-source electricity sector model to investigate potential power sector interactions of three alternative supply chains for green hydrogen in Germany in ...
