Abstract
This thesis investigates how spatial planning can enhance the techno-economic feasibility of Power- to-X (PtX) development in Aabenraa Municipality, with a focus on utilising local value chains through sector integration. PtX technologies are increas- ingly seen as key enablers for decarbonising hard- to-abate sectors, yet high electricity prices, frag- mented infrastructure, and insufficient coordination between local resources often constrain their imple- mentation. By combining a GIS-based spatial suit- ability analysis, dynamic energy system modelling, and techno-economic assessment, this study iden- tifies optimal locations for PtX facilities. It evalu- ates the impact of different system configurations. The GIS analysis reveals high-suitability areas near Kassø and Ensted port, characterised by proxim- ity 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. Re- sults show that value-chain integration, particularly waste heat utilisation and local CO2 sourcing, sig- nificantly improves Net Present Value (NPV), In- ternal Rate of Return (IRR), and Levelised Cost of Methanol (LCoM), with the integrated methanol scenario performing best economically. The find- ings highlight the importance of localised spatial planning and sector coupling in developing cost- effective and sustainable PtX projects. Municipali- ties play a critical role in enabling such integration by aligning energy planning with resource avail- ability and infrastructure. This study concludes that energy system integration, rooted in spatial data and cross-sector coordination, is essential for real- ising the full potential of PtX in Denmark
