(Re)Integrating Radioactive Materials and Waste into a Global Sustainable Development Context

The 17 Sustainable Development Goals (SDGs) of the United Nations, established in 2015, aim to achieve global sustainability by 2030 through the improvement of environmental, social, and economic parameters. However, unlike earlier concepts such as the Agenda 21 of 1992, the SDGs overlook radioactive waste management and related challenges of radiation itself. First, we investigate the historic consideration ...

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 ...

Repurposing Natural Gas Pipelines for Hydrogen: Limits and Options from a Case Study in Germany

We investigate the challenges and options for repurposing existing natural gas pipelines for hydrogen transportation. Challenges of re-purposing are mainly related to safety and due to the risk of hydrogen embrittlement of pipeline steels and the smaller molecular size of the gas. From an economic perspective, the lower volumetric energy density of hydrogen compared to natural gas is a challenge. We ...

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, ...

The Elephant in the Room: How Do We Regulate Gas Transportation Infrastructure As Gas Demand Declines? Commentary

The use of gas will decline dramatically as part of the transition to net zero. Modeling at European levelsshows that by 2050 about 70% less gaseous fuels will be used. Significant regulatory reform is needed todeal with the impacts of this decline on the gas grid.

The Future Is Battery Electric: Climate Change Mitigation in Road Freight Transport

Road freight transport must switch to alternative drive technologies, such as battery-electric or hydrogen vehicles, to mitigate its impact on the climate. Preliminary results from an ongoing research project show that the fleet of battery-electric trucks as well as the number of models on offer have recently grown significantly, albeit from a very low level. This is not the case for hydrogen trucks. ...

Catalyzing the Transition to a Climate-Neutral Industry with Carbon Contracts for Difference: Commentary

Quantifying the Dunkelflaute: An Analysis of Variable Renewable Energy Droughts in Europe

Variable renewable energy droughts, also referred to as "Dunkelflaute", emerge as a challenge for realizing climate-neutral energy systems based on variable wind and solar power. Using data on 38 historic weather years and an advanced identification method, we characterize European drought events for on- and offshore wind power, solar photovoltaics, and policy-relevant renewable technology portfolios. ...

Coping with the Dunkelflaute: Power System Implications of Variable Renewable Energy Droughts in Europe

Coping with prolonged periods of low availability of wind and solar power, also referred to as "Dunkelflaute", emerges as a key challenge for realizing a decarbonized European energy system fully based on renewable energy sources. Here, we investigate the role of long-duration electricity storage and geographical balancing in dealing with such variable renewable energy droughts. To this end, we combine ...

The Price Elasticity of Natural Gas Demand of Small Consumers in Germany during the Energy Crisis 2022

Understanding how consumers respond to turbulent market conditions is crucial for planning security of natural gas supply. This paper estimates the price elasticity of demand of small consumers in Germany in the period with both high price fluctuations and a fear of natural gas shortage in the aftermath of the Russian invasion of Ukraine. Using granular data between 2018 and 2023, we estimate an Auto ...
