Liquid air energy storage could be the lowest-cost solution for ensuring a reliable power supply on a future grid dominated by carbon-free yet intermittent energy sources, according to a new model from MIT researchers.

Iron-air batteries have a "reversible rust" cycle that could store and discharge energy for far longer and at less cost than lithium-ion technology

Although every electrical grid begins with the production of electricity, there are times when storing this power in some form instead of using it immediately is highly convenient. Today's battery-pow...

Compressed air energy storage is a sustainable and resilient alternative to chemical batteries, with much longer life expectancy, lower life cycle costs, technical simplicity, and low maintenance.

Going off-grid? Think twice before you invest in a battery system. Compressed air energy storage is the sustainable and resilient alternative to batteries, with much longer life expectancy, lower life cycle costs, technical simplicity, and low maintenance. Designing a compressed air energy storage system that combines high efficiency with small storage size is not self-explanatory, but a growing number of…

The Italian long-duration storage startup is racing to build commercial projects after proving out its CO2-based storage technology for a major Italian utility.

What's getting built in the next decade?

The startup's granular charging controls can get more energy out of second-life batteries while also detecting and preventing failures that could start fires.

The administrators of Great Britain's power grid admit that it's often unable to use energy-storage batteries due to old computer systems and an old network with "not enough cables", according to the Financial Times — though the system operator says they're making progress after upgrading thei...

(Reuters) -BlackRock, Korea's SK, Switzerland's UBS and other companies are chasing an investment boom in battery storage plants in Texas, lured by the...

In the Netherlands, Offshore Energy reported that China's largest integrated offshore photovoltaic (PV) demonstration project, combining solar power, hydrogen production and refueling, and energy storage, has been connected to the grid for power generation. Hengtong Group announced that this development marks the launch of "China's first" PV project aimed at ecological remediation of tidal flats. […]

Compressed air and hot sand are poised to reshape the grid-scale battery landscape

Enhanced geothermal systems are well suited to store excess renewable power as heat

Energy Dome is starting up a trial plant to store energy in compressed gas, but the engineering challenges might not be so simple to tackle.

Scientists have created a battery designed for the electric grid that locks in energy for months without losing much storage capacity. It's a step toward batteries that can be used for seasonal storage: saving renewable energy in one season, such as the spring, and spending it in another, like autumn.
