Compressed air can store hundreds of megawatt hours of electricity for weeks at a time. Batteries are useful for smaller volumes for shorter periods, said Rocco Vita, director of emerging technology ...

EU-funded researchers are looking to hot air to overcome the supply and demand issues faced by solar energy and ease the clean energy transition. By Michael Allen As the world shifts toward renewable ...

Newly formed firm Energy Storage and Power plans to make compressed-air energy storage machines for utilities that need storage for wind and solar power sources. Martin LaMonica is a senior writer ...

Ofgem has shortlisted energy storage projects for the new LDES cap and floor scheme, featuring Li-ion BESS, flow batteries, ...

Clean energy resources, such as wind and solar, hold untold promise for a more sustainable energy future, but a big problem with these and other clean energy resources is their intermittent nature: ...

The system consists of a reversible compressor connected to a storage unit that can be installed indoors or outdoors. The compressor must be connected to the solar panels, with the whole system being ...

Intuitively, it seems that the water displacement stores about 1/2 the energy--the other half is in the form of heat generated during compression. That's why it's so important to store that heat in a ...

Several technologies are being tested to tie large-scale storage to renewable power sources. Images: Making wind power that lasts all day Martin LaMonica is a senior writer covering green tech and ...

Decarbonizing the world's electricity grids won't be an easy task, but it is a necessary one if we're going to mitigate some of the worst effects of climate change. Since wind and solar power are ...

Every now and again you run across an idea that makes you think to yourself: “That's brilliant, yet so simple, I wonder why I didn't think of that!” In the case of electricity, we (all of us ...

Salt-water aquifers under British waters could hold 77-96 TWh of renewable-energy-powered compressed air for the two-month windows required of seasonal energy storage, according to a study conducted ...
