Abstract
Local implementation projects for sector coupling play an important role in the transformation to a more sustainable energy system. Despite various technical possibilities, there are various barriers to the realisation of local projects. Against this backdrop, we introduce an inter- and transdisciplinary approach to identifying and evaluating different power-to-X paths as well as setting up robust local implementation projects, which account for existing drivers and potential hurdles early on. After developing the approach conceptually, we exemplify our elaborations by applying them to a use case in the German city of Wuppertal. It can be shown that a mix of several interlinked interdisciplinary methods as well as several participatory elements is suitable for triggering a collective, local innovation process. However, the timing and extent of end-user integration remain a balancing act. The paper does not focus on a detailed description of power-to-X (PtX) as a central pillar of the sustainable transformation of the energy system. Rather, it focuses on the innovative methodological approach used to select a suitable use path and design a corresponding business model. The research approach was successfully implemented in the specific case study. However, it also becomes clear that the local-specific consideration entails limitations with regard to the transferability of the research design to other spatial contexts.
Highlights
There have been clear successes in the implementation of the energy system transformation in recent years, achieving the goals set at all political levels remains a major challenge in Germany [1,2]
The third step was to select the PtX path for a specific municipality or a specific supply area that is the most relevant for implementation under the local framework conditions
The systematisation of the development stages of the technology components considered here is based on the concept of the Technology Readiness Level (TRL), which was developed by NASA and is used internationally [28,29]
Summary
There have been clear successes in the implementation of the energy system transformation in recent years (especially in the electricity sector), achieving the goals set at all political levels remains a major challenge in Germany [1,2]. Given the decentralised nature of renewable energy production, local implementation projects play a important role in achieving the overarching energy system transformation goals. With regard to the latter, further efforts are required, concerning the construction of the generation units themselves as well as their integration into the existing energy system This includes, for example, expanding electricity and heat networks as well as increasing the use of energy storage facilities or sector coupling [3,4].
