Abstract:

Recovery of heat and cold including low temperature is a very important strategy for improved energy efficiency in industry. Heat and cold recovery technologies are instrumental for intra-plant optimisation and inter-plant integration to enable cascade use of heat (or cold) between cross-sectoral plants in industral parks, and with district heating/cooling networks. The heat energy often needs to be transported because the supply of heat is usually located apart from the demand. However, how to efficiently transport the heat energy over long distance is a real challenge. At the same time, there is a great deal of low-grade and middle-grade heat energies, such as solar energy, geothermal energy, and waste heat from industries and power plants, kept unused due to the relatively low thermal grade and long distance to the user sites. Therefore, developing efficient methods to overcome the transportation problems of the low-grade and middle-grade heat over long distance would contribute significantly to the reduction in energy consumption. The case study presented focuses on the possibility of heat use from the Bugey nuclear power plant (35 km away from Lyon) to provide district heating or cooling for the Lyon region in France. It is based on a new heat transportation concept over long distances. This transportation could save a large amount of fossil fuels consumption and reduce greenhouse gases emission that could be particularly harmful in densely populated areas.
