Transportation over long distance and thermal energy storage, coupling with energetic valuation processes from waste. State of art

Summary

When it comes to optimising waste-to-energy processes, energy storage and transport are two key areas. This study therefore takes stock of the technologies available or under development for long-distance transport and storage of heat energy (hot/cold) in connection with waste-to-energy processes. After a detailed presentation of existing equipment and systems in absolute terms, the link is made with waste-to-energy processes on the one hand and potential users of the heat energy transported and/or stored on the other. Finally, 3 case studies in 3 'user' sectors are discussed: housing/tertiary, laundry and the steel industry. The aim is to assess the feasibility of implementing heat energy storage and transport techniques in the waste sector. This study will be of interest to other sectors seeking to optimise their energy consumption.
