How Alternative Storage Solutions are Breaking into the Lithium-Ion-Dominated Market

Recent growth in renewable energy, spurred by state mandates, federal tax incentives, and increasingly attractive costs, has shifted attention to the use of energy storage to ensure that variable wind and solar generation reliably serve load and provide ancillary services. In this domain, lithium-ion currently dominates. But some analysts don’t see it as economically-efficient enough at scale to fully support the amount of renewable energy expected to come onto the grid, and other options are on the rise, including rail-based gravity systems, hydrogen and flow batteries.
