ENERGY CASCADING COMBINED WITH THERMAL ENERGY STORAGE IN INDUSTRY
The opportunities for energy conservation through the application of storage cascades has not previously been examined in sufficient detail to enable the overall technical and economic potential to be estimated. The objective of the research reported here, is the evaluation of this potential for UK industry. A detailed survey of a representative sample frame of UK industry has shown that the technical and economic potential represents about 1 % of the total energy use in the manufacturing sector of the UK economy. Using technical constraints based on achievable power densities for a variety of storage technologies and economic constraints based on annual charge cycle frequencies, the feasible percentage of processes has been established for a variety of storage technologies. These results have been scaled using the 1980 reference energy use as a function of process operating temperature. Final scaling of the results to determine the UK industrial potential for storage cascades was obtained by evaluating the probability of two or more 'on-site' process cascade matches. The highest probability of a satisfactory cascade match occurs in the temperature range 100 degrees C < T < 250 degrees C. Steam accumulators appear to be able to contribute most to industrial energy conservation in intermittant processes. New generations of storage technology are far less significant.
