This article examines the functionality, technologies, and environmental benefits of these storage solutions, highlighting their role in enhancing energy efficiency and reducing carbon emissions. . In recent years, improvements in energy storage technology, cost reduction, and the increasing imbalance between power grid supply and demand, along with new incentive policies, have highlighted the benefits of battery energy storage systems. Several configurations of solar energy storage systems were modelled in TRNSYS to compare the energy consumption and greenhouse gas emissions of. . Solar energy storage solutions are systems designed to capture and store energy generated from solar panels for later use, utilizing technologies such as lithium-ion batteries, pumped hydro storage, and thermal storage. ESS plays a vital role in off-grid and grid-connected communities. . Concerns about the emissions of greenhouse gases and other potentially harmful pollutants warrant examination of the emissions resulting from the operation of energy storage systems. In this study, an Excel-based model was developed to evaluate the solar power applications. Five thermal energy storage systems were considered:. .
