Modeling Variable Renewable Energy Systems: The Role of Weather Uncertainty, Heating and Long-Duration Storage

Diese Dissertation behandelt Herausforderungen bei der Modellierung variabler erneuerbarer Energiesysteme. Ein besonderer Schwerpunkt liegt auf der Rolle von Wettervariabilität und -unsicherheit, Langfristspeichern sowie dem Wärmesektor. Kapitel 1 kontextualisiert und motiviert die Fragestellungen der nachfolgenden Kapitel. Kapitel 2 testet verschiedene Konfigurationen eines stabilisierten und parallelisierten ...

Utilisation of Reactive Ionic Liquids for Energy Storage and Regulation of the Power Grid

Chlorine is an essential feedstock for polymers and pharmaceuticals, with annual production exceeding 100 Mt. Nearly all Cl2 is obtained by chlor–alkali electrolysis, which consumes about 2.58 MWh of electricity per tonne. Renewable energies such as wind and solar would lower CO2 emissions, but electrolysers would then have to adopt to fluctuating, renewable energies while downstream processes still ...

Support for Everyone or Selection of Some? Self-Selection and Assignment Into a Large-Scale Refugee Mentoring Program in Germany

Mentoring has become a popular support strategy for recently arrived immigrants and refugees, offering access to valuable information and resources. However, little is known about selection processes into mentoring programs—who chooses to enrol, who receives support, and whether these patterns are systematic. Such selection affects not only program evaluations but also broader issues of refugee integration ...

Refugees Are Feeling Increasingly Unwelcome and Perceiving Discrimination in the Labor and Housing Markets

The sentiment among refugees in Germany has changed significantly: Using Socio-Economic Panel (SOEP) data from 2016 to 2023, it can be seen that refugees have been feeling increasingly unwelcome since 2018, while their concerns about xenophobia have grown since 2019. In addition, cross-sectional data from 2022 refugees’ subjective experiences of discrimination in the workplace and when searching for ...

Dovish Coos or Hawkish Screech? From Central Bank Talk to Economic Walk

This paper investigates the effectiveness of the European Central Bank’s (ECB) communication in shaping market expectations and real economic outcomes. Using a transformer-based large language model (LLM) fine-tuned to ECB communication, the tone of monetary policy statements from 2003 to 2025 is classified, constructing a novel ECB Communication Stance Indicator. This indicator contains forward-looking ...

For a Strategic, European and Competition-Oriented Industrial Policy

The competitiveness of German industry is under significant pressure. While politiciansacknowledge the need for change, their proposed solutions remain vague and lack a clearstrategic direction. Current approaches focus on tax relief, broad investment subsidies fordomestic firms or targeted cost reductions, such as lower electricity prices. While thesemeasures may improve production conditions, they ...

Effects of Changing the Incentive Strategy on Panel Performance: Experimental Evidence From a Probability-Based Online Panel of Refugees

This study investigated how changing the mode of incentive administration between two panel waves, spaced six months apart, affected longitudinal survey response. A split-ballot incentive experiment was used to compare shifting from an unconditional pre-paid incentive mode in the first wave to a conditional post-paid mode in the second wave, versus consistently using a conditional post-paid mode across ...
