15. Longest Duration Battery Storage Installed (2023): ~10-12 Hours
Most battery storage systems today provide 4-6 hours of energy backup, but some installations now offer up to 12 hours of storage. These long-duration batteries are crucial for grid stability, as they help balance supply and demand over longer periods.
Longer-lasting storage solutions will play a key role in making renewable energy viable as a primary power source. Companies working on long-duration technologies—such as iron-air or flow batteries—have a significant opportunity to capture market share.
16. Expected Long-Duration Storage Growth (2030): 15-20% CAGR
Why Long-Duration Storage Is Poised for Explosive Growth
The long-duration energy storage (LDES) market is shifting from a niche solution to a core enabler of the renewable energy transition.
As more utilities, businesses, and industries move toward 24/7 clean power, the need for storage systems that last beyond a few hours is skyrocketing. With a projected compound annual growth rate (CAGR) of 15-20% through 2030, the sector presents a rare investment opportunity.
What’s driving this growth? It’s a mix of technological breakthroughs, government incentives, and the fundamental need to bridge the gap between intermittent energy generation and real-world power demand.
While lithium-ion batteries dominate today’s market, their limitations in storing energy for more than four hours are creating an urgent demand for alternatives.
This opens the door for next-generation storage solutions, from iron-air and flow batteries to compressed air and gravity-based systems.
17. Pumped Hydro Share in Energy Storage (2023): ~90% of Total Energy Storage
Even with the rise of batteries, pumped hydro storage still makes up about 90% of total global energy storage. These systems use water reservoirs to store energy, making them highly efficient for large-scale applications.
However, pumped hydro has geographic limitations. Batteries are stepping in to fill the gap where hydro isn’t possible. Entrepreneurs should consider hybrid systems that integrate batteries with pumped hydro or other renewable storage options to maximize efficiency.
18. Flow Batteries Share in Grid Storage (2023): ~2-5%
Flow batteries are a small but growing segment of the energy storage market, accounting for about 2-5% of grid storage. Unlike lithium-ion batteries, flow batteries don’t degrade as quickly, making them ideal for long-term applications.
While currently more expensive, flow battery costs are expected to decrease over time. Businesses working in this space should focus on improving energy density and lowering production costs to compete with lithium-ion.
