Long-term alternative to Nuku alofa mobile energy storage container

What are alternative non-battery storage technologies?

Alternative non-battery storage technologies—such as pumped hydro storage (PHS), compressed air energy storage (CAES), liquid air energy storage (LAES), gravity-based storage, and thermal energy systems (TES)—are emerging as scalable, long-lasting solutions.

Can battery technology unlock long-duration energy storage?

The batteries work fabulously for discharging a few hours of electricity, but they’re too expensive to dispatch energy for much longer. Now several companies say they have developed cheaper technologies, including flow batteries and metal-air batteries, that promise to unlock long-duration energy storage.

Are long-duration energy-storage technologies a stabilizer for new power systems?

Citation: Han M., Zheng K., Hu H., et al. (2025). Long-duration energy-storage technologies: A stabilizer for new power systems. The Innovation Energy 2:100077. Against the backdrop of realizing the target of “carbon peak and carbon neutrality”, renewable energy sources such as wind and solar power have developed rapidly.

What is the future of battery storage?

Competing long-duration storage technologies, such as flow batteries and other metal-air batteries, have also attracted billions in investment and government support. Utilities started adding batteries to the US electrical grid dramatically in 2021. Source: US Energy Information Administration.
