    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 ...

    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 ...

    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. ...

    Decentralized Energy: How 100% Renewable Energy Regions Affect Households’ Saving Behavior

    This paper focuses on decentralized energy in Germany and how households’ environmental behavior in terms of energy consumption is shaped in these contexts. It sets out to gain a more precise understanding of whether decentralized energy initiatives are a good tool to promote the adoption of renewable energies and engagement in other sustainable behaviors to mitigate global warming. This study would ...

    Uncertainties in Estimating Production Costs of Future Nuclear Technologies: A Model-based Analysis of Small Modular Reactors

    Predicting future costs of technologies not yet developed is a complex exercise that includes many uncertain parameters and functional forms. In that context, small modular reactor (SMR) concepts that are in a rather early development stage claim to have cost advantages through learning effects, standardized design, modularization, co-siting economies, and other factors, such as better time-to-market ...

    Bidirectional Coupling of the Long-term Integrated Assessment Model REgional Model of INvestments and Development (REMIND) v3.0.0 with the Hourly Power Sector Model Dispatch and Investment Evaluation Tool with Endogenous Renewables (DIETER) v1.0.2

    Integrated assessment models (IAMs) are a central tool for the quantitative analysis of climate change mitigation strategies. However, due to their global, cross-sectoral and centennial scope, IAMs cannot explicitly represent the temporal and spatial details required to properly analyze the key role of variable renewable energy (VRE) in decarbonizing the power sector and enabling emission reductions ...
