Title: Development of concepts for low-cost energy-storage assemblies for Annual Cycle Energy System applications. Summary report

Technical Report ·
OSTI ID:6248014

The objective of this program was to conceive and design ACES energy storage assemblies of low capital cost. In the search for low overall cost assemblies, many diverse concepts and materials were postulated and briefly evaluated. Cost rankings, descriptions, and discussions of the concepts have been presented from which ORNL selected the following three concepts for the Phase II development: a site-constructed tank with reinforced concrete walls formed with specialized modular blocks which eliminates most concrete form-work and provides integral R-20 insulation designated ORNLFF; a site-constructed tank with earth-supported walls that are formed from elements common to residential, in-ground swimming pools, designated SWPL; and a site-assembled tank which uses large, precast concrete sections similar to those used in underground utility vaults, designated UTLBX. Detailed designs of free-standing versions of the three concepts are presented in this report.
