Storage Revolution: Next-generation energy storage solutions, including solid-state batteries with 10,000+ charge cycles and sand batteries providing seasonal storage, are eliminating renewable energy's intermittency challenge and enabling 24/7 clean power availability. The International Energy Agency projects that global renewable power capacity will grow by 4,600 gigawatts by 2030, with solar panels alone responsible for roughly 80% of that increase. What's driving this isn't just policy or climate targets. Renewables are now cheaper than fossil fuels in most. In 2025, global annual renewable capacity additions increased by 16%, reaching 800 GW despite challenges linked to supply chain strains, grid connection delays, financial pressures and policy shifts. Solar PV accounted. MITEI's three-year Future of Energy Storage study explored the role that energy storage can play in fighting climate change and in the global adoption of clean energy grids.
