Abstract

With its ability to store and transport energy without releasing greenhouse gases, hydrogen is considered an important driver for the decarbonisation of energy systems. As future hydrogen import prices from global markets are subject to large uncertainties, it is unclear what impact different hydrogen and derivative import prices will have on the future German energy system. To answer that research question, this paper explores the impact of three different import price scenarios for hydrogen and its derivatives on the German energy system in a climate-neutral setting for Europe in 2045 using three different energy system models. The analysis shows that the quantities of electricity generated as well as the installed capacities for electricity generation and electrolysis increase as the hydrogen import price rises. However, the resulting differences between the import price scenarios vary across the models. The results further indicate that domestic German (and European) hydrogen production is often cost-efficient. • Comparison of the energy system models REMod, SCOPE SD and Enertile. • Detailed derivation of three import price scenarios for hydrogen and its derivatives. • Transformation pathways in Germany towards a climate-neutral energy system in 2045. • Increasing capacities for electricity generation and electrolysis in all models as the hydrogen import price rises. • Comparison of effects on storage technologies and electricity imports as well as on the industry and transport sectors.

8. Why Rooftops are Key for Europe’s Solar Targets

Author

Wittwer, Christof, Kost, Christoph, and Brandes, Julian

Abstract

The German energy system plays a pioneer role for transition concepts, it moves from a centralized to a decentralized structure with renewable generation. In order to reduce CO2 emissions and to address the finite nature of fossil energy resources renewables such as solar power plants, wind power plants and cogeneration plants are widely installed across Germany and Europe. Thus, the immense expected expansion of renewable and decentralised energy systems will generate a high supply of fluctuating energy in the prospective grid. With a view on Germany’s energy system, the role of PV for the transition process towards a 100 % renewable energy system will be discussed. Options to go towards prioritized decentralized rooftop PV topology versus the ground mounted utility scale PV will be discussed within the presentation.
