Balancing Cost Savings and Import Dependence in Germany's Industry Transformation
Toni Seibold, Fabian Neumann, Falko Ueckerdt +1
Greenhouse gas emissions from the steel, fertiliser and plastic industries can be mitigated by producing their precursors with green hydrogen. In Germany, green production may be e…
Price Formation in a Highly-Renewable, Sector-Coupled Energy System
Julian Geis, Fabian Neumann, Michael Lindner +2
As variable renewable energy increases and more demand is electrified, we expect price formation in wholesale electricity markets to transition from being dominated by fossil fuel…
A Minimal Methanol Backstop for High Electrification Scenarios
Philipp Glaum, Fabian Neumann, Markus Millinger +1
Electrification of sectors such as land transport and building heating is a cost-effective pathway to deep decarbonization. However, some sectors still require energy-dense fuels -…
Price formation without fuel costs: the interaction of demand elasticity with storage bidding
Tom Brown, Fabian Neumann, Iegor Riepin
Studies looking at electricity market designs for very high shares of wind and solar often conclude that the energy-only market will break down. Without fuel costs, it is said that…
Offshore power and hydrogen networks for Europe's North Sea
Philipp Glaum, Fabian Neumann, Tom Brown
The European North Sea has a vast renewable energy potential and can be a powerhouse for Europe's energy transition. However, currently there is uncertainty about how much offshore…
Energy Imports and Infrastructure in a Carbon-Neutral European Energy System
Fabian Neumann, Johannes Hampp, Tom Brown
Importing renewable energy to Europe offers many potential benefits, including reduced energy costs, lower pressure on infrastructure development, and less land-use within Europe.…
H and CO Network Strategies for the European Energy System
Fabian Hofmann, Christoph Tries, Fabian Neumann +2
Hydrogen and carbon dioxide transport can both play an essential role in climate-neutral energy systems. Hydrogen networks help serve regions with high energy demand, while excess…
Offshore Wind Integration in the North Sea: The Benefits of an Offshore Grid and Floating Wind
Philipp Glaum, Fabian Neumann, Tom Brown
Wind energy has become increasingly important for meeting Europe's energy needs. While onshore wind expansion faces public acceptance problems, for offshore wind the European Commi…
Meteorological conditions during Dunkelflauten in Germany: Characteristics, the role of weather regimes and impacts on demand
Fabian Mockert, Christian M. Grams, Tom Brown +1
Renewable generation from wind and solar power is strongly weather-dependent. To plan future sustainable energy systems that are robust to this variability, a better understanding…
Topology-based Approximations for Contingency Constraints in Power Transmission Networks
Amin Shokri Gazafroudi, Fabian Neumann, Tom Brown
It is crucial for maintaining the security of supply that transmission networks continue to operate even if a single line fails. Modeling security in power system…
PyPSA-Earth. A New Global Open Energy System Optimization Model Demonstrated in Africa
Maximilian Parzen, Hazem Abdel-Khalek, Ekaterina Fedorova +9
Macro-energy system modelling is used by decision-makers to steer the global energy transition toward an affordable, sustainable and reliable future. Closed-source models are the c…
The Potential Role of a Hydrogen Network in Europe
Fabian Neumann, Elisabeth Zeyen, Marta Victoria +1
Electricity transmission expansion has suffered many delays in Europe in recent decades, despite its significance for integrating renewable electricity into the energy system. A hy…
Long-Term Benefits of Network Boosters for Renewables Integration and Corrective Grid Security
Amin Shokri Gazafroudi, Elisabeth Zeyen, Martha Frysztacki +2
The preventative strategies for network security dominant in European networks mean that network capacity is kept free in case a line fails. If instead fast corrective action…
Broad Ranges of Investment Configurations for Renewable Power Systems, Robust to Cost Uncertainty and Near-Optimality
Fabian Neumann, Tom Brown
To achieve ambitious greenhouse gas emission reduction targets in time, the planning of future energy systems needs to accommodate societal preferences, e.g. low levels of acceptan…
Beyond cost reduction: Improving the value of energy storage in electricity systems
Maximilian Parzen, Fabian Neumann, Addrian H. Van Der Weijde +2
An energy storage technology is valuable if it makes energy systems cheaper. Traditional ways to improve storage technologies are to reduce their costs; however, the cheapest energ…
Approximating Power Flow and Transmission Losses in Coordinated Capacity Expansion Problems
Fabian Neumann, Veit Hagenmeyer, Tom Brown
With rising shares of renewables and the need to properly assess trade-offs between transmission, storage and sectoral integration as balancing options, building a bridge between e…
Costs of Regional Equity and Autarky in a Renewable European Power System
Fabian Neumann
Social acceptance is a multifaceted consideration when planning future energy systems, yet often challenging to address endogeneously. One key aspect regards the spatial distributi…
Transmission Expansion Planning Using Cycle Flows
Fabian Neumann, Tom Brown
The common linear optimal power flow (LOPF) formulation that underlies most transmission expansion planning (TEP) formulations uses bus voltage angles as auxiliary optimization var…
The Near-Optimal Feasible Space of a Renewable Power System Model
Fabian Neumann, Tom Brown
Models for long-term investment planning of the power system typically return a single optimal solution per set of cost assumptions. However, typically there are many near-optimal…
Interaction of a Hydrogen Refueling Station Network for Heavy-Duty Vehicles and the Power System in Germany for 2050
Philipp Kluschke, Fabian Neumann
A potential solution to reduce greenhouse gas (GHG) emissions in the transport sector is to use alternatively fueled vehicles (AFV). Heavy-duty vehicles (HDV) emit a large share of…
Heuristics for Transmission Expansion Planning in Low-Carbon Energy System Models
