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, ...

Energy supply security in Germany can be guaranteed even without natural gas from Russia

The Russian war on Ukraine and Germany’s dependence on Russian gas require a rethink of German energy supplies. While there is a heated debate about an immediate energy embargo, Russia could also stop its supplies at any time. To date, Germany has purchased around 55 percent of its natural gas from Russia. DIW Berlin has developed scenarios for how the German energy system could become...

Warheads of Energy: Exploring the Linkages between Civilian Nuclear Power and Nuclear Weapons in Seven Countries

This paper focuses on the causal determinants of the accumulation of nuclear weapons, also known as vertical nuclear proliferation, in China, France, India, Pakistan, Russia, UK, and the US. It empirically analyzes the causal relationships between the civilian uses of nuclear energy, military expenditures, trade openness, and the stockpiling of nuclear warheads. Results from the Toda and Yamamoto (1995) ...

On the Economics of Storage for Electricity: Current State and Future Market Design Prospects

Since the early beginnings of the electricity system, storage has been of high relevance for balancing supply and demand. Through expanded electricity production by variable renewable technologies such as wind and photovoltaics, the discussion about new options for storage technologies is emerging. In addition, the electricity markets were subject to remarkable alterations. Some developments which ...

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 ...

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 ...

Energy Transformation, Social Inclusion, and Economic Prosperity in Latin America: An Introduction

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....
