When considering the cheapest way to store solar power, options such as DIY battery systems, pumped hydro, compressed air, flywheel energy storage, molten salt tanks, ice storage, gravity systems, hydrogen fuel cells, thermal storage, and capacitor banks can offer varying costs and efficiencies.
Ember provides the latest capex and Levelised Cost of Storage (LCOS) for large, long-duration utility-scale Battery Energy Storage Systems (BESS) across global markets outside China and the US, based on recent auction results and expert interviews. 1. All-in BESS projects now cost just $125/kWh as of October 2025 2.
The cheapest form of energy storage varies based on factors like energy storage capacity, lifespan, and efficiency. Battery banks, pumped hydro, flywheel energy, compressed air, molten salt, capacitor storage, superconducting magnets, gravity storage, liquid air, and thermal storage are options to contemplate.
To sum up, these cost-effective energy storage solutions provide reliable power supply and reduce dependence on traditional sources for off-grid living. From lithium batteries to solar power banks, hydroelectric systems, wind turbine storage, and portable biomass units, these options offer sustainability and long-term cost savings.
As costs continue to drop, we expect battery storage to strengthen solar project revenues, support broader renewable deployment and accelerate the shift toward storage‑led system balancing
