Surplus heat utilization options for the neighborhood of the Future Circular Collider (FCC)

This thesis explores the efficient utilization of surplus heat generated by the Future Circular Collider (FCC), a next-generation particle accelerator planned by CERN. The FCC, with its substantial energy demands, produces significant heat during operation, which is traditionally discarded. This research focuses on assessing the feasibility of recovering this heat and reusing it for district heating, providing energy-efficient solutions for surrounding urban areas. The first part of the study analyzes the utilization rates of waste heat, demonstrating that strategies such as heat delocalization and seasonal adjustments can significantly enhance energy recovery and minimize waste. Furthermore, the research evaluates two distinct heat recovery systems: a CO2-based system and a water-based system. The results include conceptual designs for both systems, enabling a comprehensive comparison in terms of pressure drops, power requirements, pipe dimensions, and material suitability. These findings establish a foundational framework for designing efficient heat recovery systems, contribute to sustainable energy management, and offer practical insights for large-scale scientific infrastructures.
