Small change won’t do – Why we must change the system to stop the climate crisis

The Climate crisis is hurting the people who have the least resources and voice. Climate action is urgent, and must be well designed to deliver a fair transition globally, as the recently published International System Change Compass (ISCC) describes.  After the G7 summit and before the political summer break the German Institute for Economic Research (DIW Berlin) and the Open Society...

Energy supply security in Germany can be guaranteed even without natural gas from Russia

The Russian war on Ukraine and Germany’s dependence on Russian gas require a rethink of German energy supplies. While there is a heated debate about an immediate energy embargo, Russia could also stop its supplies at any time. To date, Germany has purchased around 55 percent of its natural gas from Russia. DIW Berlin has developed scenarios for how the German energy system could become...

Emobpy: A tool for time series generation of battery electric vehicles

emobpy is a Python open-source tool that enables us to generate battery electric vehicle time series. The tool was released in 2020 on Gitlab and PyPI for the first time. A description of the tool was published as an open-access article in Scientific Data. Now we have just passed the 10K downloads!. We want to reach out to everyone who uses emobpy or is...

Stranded Investments in the Coal Export Industry?

The Case of the Australian Galilee Basin Thermal coal exporters face increasing uncertainty about future coal demand and the risk of asset stranding is increasing. Nevertheless, new export-oriented coal mine projects like the Carmichael project in the Australian Galilee Basin are still brought forward. In this seminar, we discuss research results with the COALMOD-World model with Australian...

Stranded Assets in the Coal Export Industry? The Case of the Australian Galilee Basin

Steam coal exporters face increasing uncertainty about future coal demand and risks of asset stranding. Nevertheless, new export-oriented coal mine projects are still brought forward. In this study, we use the coal sector model COALMOD-World to assess the economic prospects of investments in the export-oriented steam coal sector, and in particular of coal mines in the Galilee Basin, Australia. We parameterize ...

Decarbonisation of the Energy System

Our analysis highlights that the current national energy and climate plans (NECPs) of EU countries are insufficient to achieve a cost-efficient pathway to EU-wide climate neutrality by 2050.

On the Economics of Storage for Electricity: Current State and Future Market Design Prospects

Since the early beginnings of the electricity system, storage has been of high relevance for balancing supply and demand. Through expanded electricity production by variable renewable technologies such as wind and photovoltaics, the discussion about new options for storage technologies is emerging. In addition, the electricity markets were subject to remarkable alterations. Some developments which ...

Modeling Flexibility in Energy Systems — Comparison of Power Sector Models Based on Simplified Test Cases

Model-based scenario analyses of future energy systems often come to deviating results and conclusions when different models are used. This may be caused by heterogeneous input data and by inherent differences in model formulations. The representation of technologies for the conversion, storage, use, and transport of energy is usually stylized in comprehensive system models in order to limit the size ...

Centralized and Decentral Approaches to Succeed the 100% Energiewende in Germany in the European Context – A Model-based Analysis of Generation, Network, and Storage Investments

In this paper, we explore centralized and more decentral approaches to succeed the energiewende in Germany, in the European context. We use the AnyMOD framework to model a future renewable-based European energy system, based on a techno-economic optimization, i.e. cost minimization with given demand, including both investment and the subsequent dispatch of capacity. The model includes 29 regions for ...
