Abstract
The City of Surrey in British Columbia, Canada has recently launched a district energy network (DEN) to supply residential and commercial buildings in the Surrey Centre area with hot water for space and domestic hot water heating. The network runs on natural gas boilers and geothermal exchange. However, the City plans to transition to low-carbon energy sources and envisions the DEN as a key development in reaching its greenhouse gases (GHG) reduction targets in the building sector. Harvesting and utilizing waste heat from industrial sites is one of the attractive alternative energy sources that Surrey is considering. In this study, a techno-economic analysis (TEA) was conducted to determine the energy storage density (ESD) of the proposed Mobile Thermal Energy Storage (M-TES) technology, costs, and the emission reduction potential of integrating waste heat into Surrey’s DEN. Three transportation methods were considered to determine the most cost-effective and low-carbon option(s) to transfer heat from industrial waste heat locations at various distances (15km, 30km,45km) to district energy networks, including i) a diesel truck; ii) a renewable natural gas-powered (RNG) truck, and iii) an electric truck. To evaluate the effectiveness of mobile thermal energy storage (M-TES), the cost of emission reduction ($/tCO2e avoided) is compared with business as usual (BAU), which is using a natural gas boiler only. The minimum system-level ESD that makes M-TES competitive when compared to other low carbon energy sources was 0.4 MJ/kg.
