The German energy transition repeatedly faces harsh critiques questioning its economic and environmental merit. This article defends the Energiewende and argues that Germany has chosen a rational and particularly forceful approach to securing sustainable energy supply. Though current...

We develop a dispatch and investment model to study the role of power storage and other flexibility options in a greenfield setting with high shares of renewables. The model captures multiple system values of power storage related to arbitrage, dispatchable capacity, and reserves. In a baseline...

The German "traffic light" (Ampel) coalition has set ambitious new energy transition targets. Using an open data tool developed at DIW Berlin, we discuss the progress and challenges of selected indicators. Since the government took over, photovoltaic capacity increased by 45 % to 87 GW by April...

Die Beschleunigung der Energiewende ist erklärtes Ziel der Ampel-Koalition. Eine Schlüsseltechnologie ist die Photovoltaik (PV), die derzeit weltweit einen regelrechten Boom erlebt. Der Ampel-Monitor Energiewende des DIW Berlin zeigt: Auch in Deutschland hat der PV-Zubau stark Fahrt...

Emission-free hydrogen (H2) is crucial to decarbonize energy supply and to tackle the climate crisis. To unlock the potential of H2, pipelines infrastructures and related investments are required to enable trade. However, it is uncertain what future H2 infrastructure will be needed. The paper...

We examine the effects of future renewable expansion in Germany on residual load and renewable surplus generation for policy-relevant scenarios for 2022, 2032 and 2050. We also determine the storage capacities required for taking up renewable surpluses for varying levels of accepted curtailment....

Recent developments in electricity markets such as the increased deployment of variable renewable generation have prompted renewed interest over the role of energy storage. While storage technologies can in principle provide various benefits for the functioning of an electrical grid, many energy...
