With nuclear reactor fleets continuously aging, the decommissioning of closed reactors is gaining increasing attention. In nuclear decommissioning, technical, organizational, and regulatory challenges lead to long project durations and cost escalations. This paper attempts to examine the organizational efficiencies in nuclear decommissioning by applying the framework of the "system good" analysis and ...

The decarbonization of buildings requires the phase-out of fossil fuel heating systems. Heat pumps are considered a crucial technology to supply a substantial part of heating energy for buildings. Yet, their introduction is not without challenges, as heat pumps generate additional electricity demand as well as peak loads. To better understand these challenges, an ambitious simultaneous heat pump rollout ...

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. ...

Sweden is at the forefront of the transition of its energy sector to low-carbon technologies with profound consequences for both energy generation and its distribution. However, the impact of this transition on the performance of Electricity Distribution System Operators (DSOs) has not been thoroughly studied. The article addresses this gap by using a novel approach and detailed georeferenced firm-level, ...

With the increasing urgency to address climate change, understanding public sentiment is crucial for designing effective and socially acceptable environmental policies. Despite the existence of effective tools for the green transition, a significant obstacle for policymakers lies in the lack of public support, hindering their ability to utilize these tools effectively. One tool that has been...

We examine the impact of the war in Ukraine on long-term contracts in energy markets. We find that traded contract volumes fall by 65 percent in the first months of the war. A collapse in bilateral trading contributes most to this decline. To protect themselves from price shocks, firms increasingly turned to long-term contracts already before the war. In sum, our results show that the market continued ...

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

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, ...

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, ...
