Gravity Batteries for Integrating Renewable Energy into Power Grids

The growing adoption of renewable energy sources, such as wind and solar power, has introduced new challenges in maintaining a stable and reliable electricity supply. This paper explores the potential of gravity battery systems as an innovative solution to address the intermittent nature of renewable energy generation and enhance demand-side management. With the increasing emphasis on reducing greenhouse gas emissions and transitioning to a sustainable energy future, finding efficient methods for energy storage and utilization is of paramount importance. The core focus of the research is to determine the optimal capacity of gravity batteries required to effectively smooth out renewable energy fluctuations and support grid stability. This paper commences with an extensive analysis of the current electricity consumption patterns in Britain, using historical data and trends to understand the variations in energy demand, and indicates that repurposing abandoned mines for gravity-based energy storage offers a viable solution. This information serves as a benchmark for evaluating the feasibility and efficiency of gravity battery integration. MATLAB simulation evaluates gravity battery integration feasibility and efficiency, determining optimal capacity to smooth renewable energy fluctuations and support grid stability.
