    Potenziale einer Wasserstoffwirtschaft aus wirtschaftlicher und gesellschaftlicher Perspektive
    Um ein umfassendes Gesamtbild für eine zukünftige Wasserstoffwirtschaft zu zeichnen, werden unterschiedliche Szenarien für Klimaziele und Energienachfrage betrachtet und die wesentlichen Themen wirtschaftliche Relevanz, Wertschöpfung, Klimabeitrag, Akzeptanz und Nachfrage von Wasserstoff beleuchtet. Das Kapitel startet mit einem Abschnitt zur wirtschaftlichen Relevanz von Wasserstoff sowie darauf basierenden Syntheseprodukten und gibt einen Ausblick auf den potenziellen Wasserstoffmarkt der Zukunft. Es zeigt die Wertschöpfungskette einer klimaneutralen Wasserstoffwirtschaft auf und thematisiert resultierende Umsatz- und Arbeitsmarktpotenziale und letztlich die damit verbundenen Chancen für die deutsche Industrie. Im Anschluss wird der Beitrag zur Erreichung von Klima- und Umweltzielen durch den Einsatz von Wasserstoff diskutiert, wobei das Treibhausgasminderungspotenzial der Wasserstoffherstellung in Abhängigkeit seiner Rohstoffe beschrieben wird. Schließlich werden drei wesentliche Dimensionen für die Akzeptanz und den Abbau von Barrieren für eine Wasserstoffwirtschaft thematisiert und abschließend die Herausforderungen und Chancen einer Wasserstoffwirtschaft für die wesentlichen Nachfragesektoren Industrie, Verkehr, Wärme und Energie diskutiert.

    The potential of a hydrogen economy: an economic and social perspective
    In order to create a comprehensive overview of a future hydrogen economy, different climate target and energy demand scenarios will be considered and the key issues of economic relevance, value creation, climate protection, public support and demand for hydrogen will be examined. This chapter starts with a section on the economic relevance of hydrogen and hydrogen-based synthesis products and makes predictions as to how a potential hydrogen market may develop in the future. It then discusses the value chain that would result from a climate-neutral hydrogen economy and addresses the sales and labor market potential that chain would give rise to. Lastly, it highlights the opportunities this would present for German industry. Subsequently, the chapter focuses on how the use of hydrogen can help achieve climate and environmental targets, including an explanation of how hydrogen production can potentially help to reduce greenhouse gas generation, depending on which raw materials are used. Finally, three essential factors for achieving public support for and removing the barriers to a hydrogen economy will be discussed, followed by the challenges and opportunities that a hydrogen economy would present for the key demand sectors of industry, transportation, heating and energy.

    Disruptive demand side technologies: Market shares and impact on flexibility in a decentralized world
    Electricity demand is expected to increase strongly as electrification and the use of hydrogen are promising decarbonization options for the demand side sectors transport and industry. In a decentralized system with volatile renewable energy sources, flexibility potentials will play an important role for secure and cost-efficient electricity supply. On the demand side, decentralized PV-battery systems and electric vehicles as well as hydrogen production by electrolyzers could provide the necessary flexibility. Energy demand over time is calculated based on assumed and simulated market shares of these and other low-emission technologies. Impacts on the system and residual load are analyzed, with a focus on the contribution of load shifting as a demand-side measure. Results indicate that load shifting can contribute significantly to integrate RES electricity.

    European final energy consumption mainly stems from five sectors: transport, households, industry, residential, and agriculture using fossil fuels as dominant energy carriers. In order to achieve the climate targets, emissions in the demand sectors must be drastically reduced. Due to different characteristics and challenges each sector needs its own strategy how to achieve such decarbonization until 2050. In the following chapter, the impacts of an ambitious mitigation scenario on future energy demand and CO2 emissions for transport, industry, residential, and tertiary are analyzed discussing sector specific decarbonization strategies and mitigation options. Implications of such strategies for demand-side flexibility and its future need are analyzed.
