    Planning Macro-energy Systems with Multiple Climatic Years: A Quadratic Trust-region Approach for Benders Decomposition

    This paper applies Benders decomposition to two-stage stochastic problems for energy planning with multiple climatic years, a key problem for the design of renewable energy systems. First, we implement Benders decomposition with existing enhancements suited for the characteristics of the problem, a simple continuous masterproblem and fewbut large sub-problems. Next, we develop a novel trust-region ...

    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 ...

    Electricity supply in Germany can be secured without Russian supplies and nuclear energy; the 2030 coal-phase out remains possible

    The European Union has increased pressure on Russia by enacting a coal embargo. Following a transition period, Russian coal imports will end in August 2022. Recent studies show that Germany will be able to substitute Russian supplies with imports from other countries by summer 2022. However, with the looming threat of a Russian gas supply stop, plans must be developed to ensure security of supply....

    Plans for Expanding Nuclear Power Plants Lack Technological and Economic Foundations

    In mid-April 2023, the final three nuclear power plants in Germany will be taken offline permanently. At the same time, the energy crisis resulting from the Russian invasion of Ukraine has fueled calls for the construction of new nuclear reactors in Germany. A similar debate is taking place in many other countries in the context of the climate crisis. Since the 1950s, nuclear power has been one of ...

    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 ...

    How Flexible Electrification Can Integrate Fluctuating Renewables

    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 ...

    Reacting to Changing Paradigms: How and Why to Reform Electricity Markets

    The energy crisis and the accelerated transition to climate neutrality result in a shift from the traditional energy trilemma to an “energy quartet” across Europe. Firstly, the criteria of affordability, previously focused on short-term price developments, broadens to reliable affordability including in crises. Secondly, clean energy traditionally focused on clean production now extends to clean energy ...
