    Heimische Produktion von grünem Wasserstoff kann mit Kavernenspeicherung günstiger werden

    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, ...

    Nationale Wasserstoffstrategie konsequent und mit klarem Fokus umsetzen

    Der Ersatz fossiler durch erneuerbare Energieträger ist ein wesentlicher Baustein der Energiewende. In bestimmten Bereichen soll künftig grüner Wasserstoff eine wichtige Rolle spielen. Dies geht auch aus der überarbeiteten Nationalen Wasserstoffstrategie hervor, die die Bundesregierung kürzlich vorgestellt hat. In diesem Wochenbericht werden wichtige Änderungen gegenüber der ersten Fassung aus dem ...

    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 ...

    National Hydrogen Strategy: Clear Focus and Consistent Implementation Necessary

    Replacing fossil fuels with renewable energy sources is one cornerstone of the energy transition. In certain sectors, green hydrogen will play an important role in the future, as is envisioned in the revised National Hydrogen Strategy recently presented by the German Federal Government. This Weekly Report discusses important changes in this strategy compared to the first National Hydrogen Strategy ...

    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; ...

    A Linear Reduced-Order Model for the Activated Sludge Process For the Integration into a Mixed-Integer Linear Energy System Optimisation Model

    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. ...

    Power Sector Effects of Green Hydrogen Production in Germany

    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 ...

    Flexible Heat Pumps: Must-Have or Nice to Have in a Power Sector with Renewables?

    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 ...
