Focus of the month: Energy storage beyond Lithium-ion: Technologies, market movements and cost of storage (12)

Redox-flow batteries are the most common alternative to Li-ion batteries, but other technologies attempt to capture market shares (12)

Main contenders to Li-ion batteries (12)

Redox flow batteries are developed at the MW-scale, but deployments remain rare (14)

Vanadium flow batteries express highly volatile electrolyte prices that directly impact the technology’s cost of storage and lead to market uncertainty (15)

While numerous, flow battery manufacturers have different evolution perspectives and business attractiveness levels (17)

Mergers and acquisitions beyond lithium-ion  (18)

Lithium-ion batteries are likely to remain the most cost-competitive technology, unless claims from alternative providers become real (18)

Levelized Cost of storage of a typical grid-connected energy storage system (19)

Levelized Cost of storage of a solar-plus-storage system and comparison with CSP (21)

Appendix – Assumptions considered (22)
