Cover Story: This feasibility study investigates extracting thermal energy from the Bedretto tunnel in the Swiss Alps. Our findings indicate that flowing water is the most effective heat source. Estimates indicate that the total extractable thermal energy ranges between 0.8 MWth and 1.5 MWth after reducing the water temperature to 4 °C via a heat pump. This study identifies the most suitable energy sourcing locations based on efficiency and investment costs. Cost analyses reveal that the investment in piping and heat pumps can be amortized within the equipment’s lifespan with appropriate economic models. With the same initial investments, district heating systems are viable in villages with over 30 connections. The payback periods are 10 years for 60 connections, 4.5 years for 90 connections, and immediate for 200 connections. View this paper
