“…However, for the countries outside Germany, a reduced technology scope is considered, which may have an impact on the observed cross-border power flows and the required balancing technologies. Compared to previous works [39,40], the REMix results show a different allocation of electrolysers, which is caused by a different technology scope, deviation assumptions regarding VRE potentials, and the neglect of hydrogen imports. This also drives differences in the corresponding storage and pipeline infrastructure.…”

In which way, and in which sectors, will renewable energy be integrated in the German Energy System by 2030, 2040, and 2050? How can the resulting energy system be characterised following a −95% greenhouse gas emission reduction scenario? Which role will hydrogen play? To address these research questions, techno-economic energy system modelling was performed. Evaluation of the resulting operation of energy technologies was carried out from a system and a business point of view. Special consideration of gas technologies, such as hydrogen production, transport, and storage, was taken as a large-scale and long-term energy storage option and key enabler for the decarbonisation of the non-electric sectors. The broad set of results gives insight into the entangled interactions of the future energy technology portfolio and its operation within a coupled energy system. Amongst other energy demands, CO2 emissions, hydrogen production, and future power plant capacities are presented. One main conclusion is that integrating the first elements of a large-scale hydrogen infrastructure into the German energy system, already, by 2030 is necessary for ensuring the supply of upscaling demands across all sectors. Within the regulatory regime of 2020, it seems that this decision may come too late, which jeopardises the achievement of transition targets within the horizon 2050.

“…Thus, we do not consider potential future imports. Yet, other studies have shown that Germany is expected to import a major share of its hydrogen needs [35][36][37], which is also acknowledged by the German government [38]. If domestic production of hydrogen would be lower due to higher imports, the power sector effects were smaller than identified here.…”

The use of green hydrogen can support the decarbonization of sectors which are difficult to electrify, such as industry or heavy transport. Yet, the wider power sector effects of providing green hydrogen are not well understood so far. We use an open-source electricity sector model to investigate potential power sector interactions of three alternative supply chains for green hydrogen in Germany in the year 2030. We distinguish between model settings in which Germany is modeled as an electric island versus embedded in an interconnected system with its neighboring countries, as well as settings with and without technology-specific capacity bounds on renewable energies. Our analysis aims to inform other energy system modelers as well as policy makers. The findings suggest that large-scale hydrogen storage can provide valuable flexibility to the power system in settings with high renewable energy shares. These benefits are more pronounced in the absence of flexibility from geographical balancing. We further find that the effects of green hydrogen production on the optimal generation portfolio strongly depend on the model assumptions regarding capacity expansion potentials. We also identify a potential distributional effect of green hydrogen production at the expense of other electricity consumers, of which policy makers should be aware.

“…Wasserstoff spielt eine fundamentale Rolle als Energieträger sowohl bei der Dekarbonisierung des Energiesystems als auch generell bei der Transformation der Wirtschaft hin zu mehr Nachhaltigkeit und Klimaneutralität 1–6. Für die gesamte Prozesskette von der Erzeugung über den Transport bis hin zur Nutzung des Wasserstoffs hat die Einhaltung bestimmter stofflicher Parameter essenzielle Bedeutung, wobei besonders die Gasfeuchte als kritische Größe zu nennen ist.…”

Die Feintrocknung spielt eine Schlüsselrolle für den Einsatz und insbesondere die Einspeisung von Wasserstoff in die Erdgasinfrastruktur. Zur thermischen Regenerierung des Trockenmittels können Radiowellen für eine direkte dielektrische Erwärmung des Schüttbettes eingesetzt werden. In Abhängigkeit von den verwendeten Zeolithen, NaX oder NaY, sind dabei sowohl eine homogene Erwärmung als auch eine selektive Erwärmung der wasserbeladenen Trockenmittelschüttungen möglich. Nach entsprechenden Tests steht nunmehr ein einsatzfähiger druckfester Prototyp für die Wasserstofftrocknung zur Verfügung.
