Break-even and optimization conditions for overall energy systems wherein hydrogen storage facilities are used

Abstract

Technoeconomic aspects of large-scale hydrogen storage are discussed, especially with regard to their impact on the overall economics of the energy system wherein hydrogen storage is used. In the case of hydrogen-cycle electricity storage the direct economic advantages are at best marginal, but there are a number of indirect benefits (due to modularity and fast-response properties) to be accounted for. In hydrogen energy systems with hydrogen end use following the usual load-duration curve the economic advantages of hydrogen storage are very clear.
