Abstract
This thesis investigates how spatial planning can enhance the techno-economic feasibility of Powerto-X (PtX) development in Aabenraa Municipality, with a focus on utilising local value chains through sector integration. PtX technologies are increasingly seen as key enablers for decarbonising hardto-abate sectors, yet high electricity prices, fragmented infrastructure, and insufficient coordination between local resources often constrain their implementation. By combining a GIS-based spatial suitability analysis, dynamic energy system modelling, and techno-economic assessment, this study identifies optimal locations for PtX facilities. It evaluates the impact of different system configurations. The GIS analysis reveals high-suitability areas near Kassø and Ensted port, characterised by proximity to wastewater treatment, biogenic CO2 sources, and district heating networks. Four PtX scenarios are modelled, ranging from standalone hydrogen production to integrated e-methanol synthesis. Results show that value-chain integration, particularly waste heat utilisation and local CO2 sourcing, significantly improves Net Present Value (NPV), Internal Rate of Return (IRR), and Levelised Cost of Methanol (LCoM), with the integrated methanol scenario performing best economically. The findings highlight the importance of localised spatial planning and sector coupling in developing costeffective and sustainable PtX projects. Municipalities play a critical role in enabling such integration by aligning energy planning with resource availability and infrastructure. This study concludes that energy system integration, rooted in spatial data and cross-sector coordination, is essential for realising the full potential of PtX in Denmark
