    Der Angriffskrieg von Russland auf die Ukraine hat auf vielen Seiten zur Erkenntnis geführt, dass die bisher geltende Gewissheit, dass enge Handelsbeziehungen zu einer stabilen Energieversorgung führen, zu hinterfragen ist. Das Zukunftsthema Wasserstoff ist davon in besonderem Maße betroffen. Vor diesem Hintergrund beschäftigt sich das Impulspapier unter anderem mit neuen Ansätzen der Bewertung von Partnerländern beim Wasserstoffimport, der Entwicklung von Importkosten und den Potenzialen für eine Wasserstoffherstellung in der EU. Zudem geht das Papier auf die künftige wirtschaftliche Entwicklung der Ukraine durch die Erzeugung und den Transport von Wasserstoff ein.

    With the 2015 Paris Climate Agreement, the international community has reaffirmed its commitment to tackle anthropogenic climate change with the goal of limiting the global average temperature increase below 1.5 °C, but to a maximum of 2 °C above pre-industrial levels. Against this background, we examine scenarios for a complete decarbonisation of the European energy supply. Since such scenarios are based on a high expansion of weather-dependent renewable energy sources, the question arises, which flexible technologies are necessary to balance supply and demand in such energy systems. In this paper, a scenario analysis shows which capacity or volume of energy storage, power interconnectors and synthetic fuels are needed in decarbonization scenarios. To address this research question three different energy system models are applied. These models cover Europe and Germany, respectively, and are able to explain different results of the single models based of the corresponding model characteristics. The paper concludes that the power sector is able to cover a considerable share of the energy demand in the heat and transport sector with the help of flexible sector coupling technologies such as heat pumps and electric mobility. All considered models manage to find solutions for a deep decarbonization if flexibility and storage option are available.

    The transformation of the energy system is a highly complex process involving many dimensions. Energy system models help to understand the process and to define either target systems or policy measures. Insights derived from the social sciences are not sufficiently represented in energy system models, but address crucial aspects of the transformation process. It is, therefore, necessary to develop approaches to integrate results from social science studies into energy system models. Hence, as a result of an interdisciplinary discourse among energy system modellers, social scientists, psychologists, economists and political scientists, this article explains which aspects should be considered in the models, how the respective results can be collected and which aspects of integration into energy system models are conceivable to provide an overview for other modellers. As a result of the discourse, five facets are examined: Investment behaviour (market acceptance), user behaviour, local acceptance, technology innovation and socio-political acceptance. Finally, an approach is presented that introduces a compound of energy system models (with a focus on the macro and micro-perspective) as well as submodels on technology genesis and socio-political acceptance, which serves to gain a more fundamental knowledge of the transformation process.
