Abstract
Gravity Energy Storage (GES) is an emerging renewable energy storage technology that uses suspended solid weights to store and release energy. This study is the first to investigate the feasibility of using unstabilized Compressed Earth Blocks (uCEBs) as a cost-effective and sustainable alternative for weight manufacturing in GES systems. The analysis demonstrates that uCEBs offer competitive advantages over conventional materials in terms of density and cost. The relatively low strength requirements of weights allow for CEB production without stabilizers, reducing manufacturing time and capital costs. The study highlights potential of uCEBs for GES and describes the manufacturing method. Overall, uCEBs represent a promising option to enhance GES efficiency and affordability.
