Reducing Energy System Model Distortions from Unintended Storage Cycling through Variable Costs

Energy system models are used for policy decisions and technology designs. If not carefully used, models give implausible outputs and mislead decision-making. One implausible effect is “unintended storage cycling”, which is observable as simultaneous storage charging and discharging. Methods to remove such misleading effects exist, but are computationally inefficient and sometimes ineffective. Through ...

A Collective Blueprint, Not a Crystal Ball: Overcoming Political Stalemates: The German Stakeholder Commission on Phasing out Coal

The future of coal remains contested in many countries, hindering necessary energy transitions. Collaborative governance approaches, such as stakeholder commissions, have been proposed as potential solution to resolve such societal conflicts. In Germany, a stakeholder commission process managed to overcome the existing stalemate situation, leading to the adoption of a coal phase-out by 2038. Celebrated ...

Geographical Balancing of Wind Power Decreases Storage Needs in a 100% Renewable European Power Sector

To reduce greenhouse gas emissions, many countries plan to massively expand wind power and solar photovoltaic capacities. These variable renewable energy sources require additional flexibility in the power sector. Both geographical balancing enabled by interconnection and electricity storage can provide such flexibility. In a 100% renewable energy scenario of twelve central European countries, we investigate ...

Energy Transition Metals: Bottleneck for Net-Zero Emissions?

The energy transition requires substantial amounts of metals, including copper, nickel, cobalt, and lithium. Are these metals a bottleneck? We identify metal-specific demand shocks, estimate supply elasticities, and study the price impact of the transition in a structural scenario analysis. Prices of these four metals would reach previous historical peaks but for an unprecedented, sustained period ...

Accounting for Spatiality of Renewables and Storage in Transmission Planning

The current governance process to plan the German energy system omits two options to substitute grid expansion: First, placing renewables closer to demand instead of where site conditions are best. Second, utilizing storage instead of additional transmission infrastructure to prevent grid congestion. In the paper, we apply a comprehensive capacity expansion model based on the AnyMOD modeling framework ...

ECB Can Lower Fuel and Heating Costs by Increasing Interest Rates but Would Risk Economic Recovery

Inflation has been growing considerably since the middle of 2021, with rising energy prices driving the increase in particular. Since the end of February 2022, the trend has also been exacerbated by the ongoing Russian invasion of Ukraine. To keep prices stable, the European Central Bank must rein in its accommodative monetary policy. However, would doing so—by enacting an interest rate increase, for ...

The Expansion of Natural Gas Infrastructure Puts Energy Transitions at Risk

Whether additional natural gas infrastructure is needed or would be detrimental to achieving climate protection goals is currently highly controversial. Here we combine five perspectives to argue why expansion of the natural gas infrastructure hinders a renewable energy future and is no bridge technology. We highlight that natural gas is a fossil fuel with a significantly underestimated climate impact ...

Substituting Clean for Dirty Energy: A Bottom-Up Analysis

We fit CES and VES production functions to data from a numerical bottom-up optimization model of electricity supply with clean and dirty inputs. This approach allows for studying high shares of clean energy not observable today and for isolating mechanisms that impact the elasticity of substitution between clean and dirty energy. Central results show that (i) dirty inputs are not essential for production. ...
