    Measuring the Dunkelflaute: How (not) to Analyze Variable Renewable Energy Shortage

    As variable renewable energy (VRE) sources increasingly gain importance in global energy systems, there is a growing interest in understanding periods of VRE shortage ('Dunkelflauten'). Defining, quantifying, and comparing such shortage events across different renewable generation technologies and locations presents a surprisingly intricate challenge. Various methodological approaches exist in different ...

    Ampel-Monitor Energiewende: ambitionierte Ziele, aber zu geringe Dynamik

    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 2024, with a planned doubling by 2030. However, onshore wind power grew by only 11 % to 62 GW. The installation ...

    Renewable Energy and Equilibrium Hedging in Electricity Forward Markets

    We study the impact of renewable energy on forward markets for electricity. Previous literature shows that forward prices are determined by time-varying demand and volatile spot prices. We introduce supply risk from renewable generation and find that stochastic renewable output mitigates income risk for generating firms, in particular when negative shocks to renewable output have large positive price ...

    Options for Importing Green Hydrogen into Germany by 2030: Transportation Routes, Country Assessments and Implementation Requirements ; Analysis

    Whether or not Germany can be carbon-neutral by 2045 will also depend on whether hydrogen can be successfully utilised. The ramp-up of a green hydrogen economy which includes a substantial, industrial-scale supply of hydrogen by 2030 is an ambitious goal. The strong rise in the demand for green hydrogen and its synthesis products by industry (e.g. steel, chemical and glass industries), transport (shipping, ...

    Cream-skimming through PPAs – Interactions between Private and Public Long-term Contracts for Renewable Energy

    Public support systems and private investments in renewable energy are increasingly existing side-by-side and are both emphasized in policy proposals on the European and national levels. This paper assesses the interaction between the two approaches with respect to cream-skimming, i.e., the potential for low-cost projects to sign private contracts that increase the costs of publicly supported renewable ...

    Power Sector Effects of Alternative Options for De-fossilizing Heavy-duty Vehicles - Go Electric, and Charge Smartly

    Various options are discussed to de-fossilize heavy-duty vehicles, including battery-electric vehicles (BEVs), electric road systems (ERS), and indirect electrification via hydrogen fuel cells or e-fuels. We investigate their power sector implications in future scenarios of Germany, with high renewable energy shares, using an open- source capacity expansion model and route-based truck traffic data. ...

    Advancing Sustainable Development Goals through Energy Access: Lessons from the Global South

    Under the banner of the United Nations' Sustainable Development Goal 7 (SDG 7), governments, industry, and civil society organisations have supported many energy access projects since 2015. Notably, funding and investments allotted to renewable energy are regarded not only to provide ‘energy for all’ but also support the delivery of other SDGs related to climate change, food security, health, and poverty ...

    Comparison of the Environmental Impacts of Heating Systems in Chile by Life Cycle Assessment

    The present study conducts a Life Cycle Assessment (LCA) to evaluate the environmental impacts of heating technologies commonly used in Chile based on six environmental indicators: Climate Change (CC), Human Toxicity (HT), Formation of Particulate Matter (PM), Formation of Photochemical Oxidants (PO), Ozone Destruction (OD), and Water Depletion (WD). Due to the extensive length of the territory studied, ...

    Questioning Nuclear Scale-up Propositions: Availability and Economic Prospects of Light Water, Small Modular and Advanced Reactor Technologies

    This paper addresses the pressing need for rapid decarbonization of energy systems by examining the role of nuclear power in future energy scenarios collected in the IPCC database. Despite their explorative character, energy scenarios can influence decision-makers or might be used to promote certain technology developments. They are increasingly subject to the integration into real-world settings and ...
