These developments pave the way for more efficient and durable energy storage solutions tailored for solar energy applications.

3.2 Diversification of Storage Methods

Innovation in energy storage also includes exploring diverse methods beyond conventional batteries. Hydrogen storage is a concept gaining traction, where excess energy generated from solar panels can be converted into hydrogen through electrolysis. This hydrogen can later be utilized in fuel cells or combusted to produce electricity, offering an extended storage duration with higher capacities. Additionally, gravity-based energy storage systems are emerging as a sustainable solution that relies on lifting and lowering heavy masses to store energy. Such diversification of storage methods is essential for developing a resilient and sustainable energy grid that maximizes the benefits of solar energy.
