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 ...

Erfolgreicher Klimaschutz durch zügigen Kohleausstieg in Deutschland und Nordrhein-Westfalen

Die Stromerzeugung aus Braun- und Steinkohle war im Jahr 2016 für mehr als ein Viertel der deutschen Treibhausgas- Emissionen verantwortlich. Unter den Bundesländern ist Nordrhein-Westfalen der mit Abstand größte CO2-Emittent. Um die nationalen Klimaziele zu erreichen, werden daher gegenwärtig alternative Kohleausstiegspfade diskutiert, unter anderem in der Kommission „Wachstum, Strukturwandel und ...

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; ...

Successful Climate Protection via Rapid Coal Phaseout in Germany and North Rhine-Westphalia

Power generation from lignite and hard coal was responsible for more than a quarter of German greenhouse gas emissions in 2016. Of all federal states, North Rhine-Westphalia is by far the largest carbon emitter. The Growth, Structural Change and Regional Development Commission (also known as “Coal Commission”) among others are currently debating alternative pathways toward a coal phaseout to achieve ...

Renewable Energy Targets and Unintended Storage Cycling: Implications for Energy Modeling

To decarbonize the economy, many governments have set targets for the use of renewable energy sources. These are often formulated as relative shares of electricity demand or supply. Implementing respective constraints in energy models is a surprisingly delicate issue. They may cause a modeling artifact of excessive electricity storage use. We introduce this phenomenon as “unintended storage cycling”, ...

Impacts of Power Sector Model Features on Optimal Capacity Expansion: A Comparative Study

The transition towards decarbonized energy systems requires the expansion of renewable and flexibility technologies in power sectors. Many powerful tools exist to find optimal capacity expansion. In a stylized comparison of six models, we evaluate the capacity expansion results of basic power sector technologies. The technologies under investigation include base- and peak load power plants, electricity ...

Model-Related Outcome Differences in Power System Models with Sector Coupling: Quantification and Drivers

This paper presents the results of a multi-model comparison to determine outcome deviations resulting from differences in power system models. We apply eight temporally and spatially resolved models to 16 stylized test cases. These test cases differ in their renewable energy supply share, technology scope, and optimization scope. We focus on technologies for balancing the variability of power generation, ...

Modeling Flexibility in Energy Systems — Comparison of Power Sector Models Based on Simplified Test Cases

Model-based scenario analyses of future energy systems often come to deviating results and conclusions when different models are used. This may be caused by heterogeneous input data and by inherent differences in model formulations. The representation of technologies for the conversion, storage, use, and transport of energy is usually stylized in comprehensive system models in order to limit the size ...
