Abstract

This article offers a comprehensive analysis of Cold Thermal Energy Storage (CTES) systems as a realistic and cost-effective alternative to conventional renewable energy investments in the context of Israel’s energy strategy. The study begins by assessing the global progress of green technologies—such as solar, wind, and battery storage—and highlights their fundamental limitations, including intermittency, high disposal costs, and dependency on subsidies. Against this backdrop, the article evaluates the technical maturity and operational benefits of CTES systems, especially those utilizing liquid and pumpable ice. These systems enable demand-side energy shifting, reduce peak loads, and enhance grid resilience. Drawing on international data and case studies from Israel’s commercial and high-tech infrastructure, the paper proposes integrating CTES as a key component in achieving energy efficiency, climate adaptation, and national energy security.
