Role of Thermal Energy Storage in Industrial Energy Conservation

摘要

Thermal energy storage for industrial applications is a major thrust of DOE's Thermal Energy Storage Program. Utilizing Thermal Energy Storage (TES) with process- or reject-heat recovery systems has been shown to be extremely beneficial for several applications. Recent system studies resulting from contracts awarded by DOE have identified four especially significant industries where TES appears attractive--food processing, paper and pulp, iron and steel, and cement. Potential annual fuel savings with large-scale implementation of near-term TES systems for these industries is over 9 x 10 exp 6 bbl of oil. This savings is due to recuperation and storage in the food-processing industry, direct fuel substitution in the paper and pulp industry, and reduction in electric-utility peak fuel use through in-plant production of electricity from utilization of reject heat in the steel and cement industries.
