This report is the result of the research project "Transformation and technical connection of Urban Energy Infrastructures", which is part of the "Framework Programme for the Implementation of the Energy Transformation in the Municipalities of the Ruhr Area – Energiewende Ruhr".
The transformation of the energy infrastructure, in a region still predominantly oriented towards central generation and corresponding supply systems, is one of the major challenges of a successful energy transition – even if only part of these challenges can be met in the region itself.
Within the project, central technological and infrastructural challenges were analysed in the context of the implementation of the energy transition on local level. Of particular interest here was how the targeted connection of different infrastructure sectors (electricity, heat, transport) can contribute to exploit efficiency potentials and thus create a sustainable infrastructure system. The analyses focused on the areas of combined heat and power (CHP) and hydrogen.
Up to now, such medium- and long-term transformation processes have often been described solely by technology-focused scenarios and strategies. This approach is increasingly proving to be to restrictive because it is too narrowed to individual technology areas and does not take into account the systemic interaction. In addition, other factors (user behaviour, investment decisions, financial decisions on the consumer side, networks of stakeholders, etc.) are usually considered only marginally. The project therefore chose the methodological approach of a cross-impact-analysis in order to design discursively and participatory qualitative visions of the future for the technology areas.
