Five hundred meters below the Pacific, off the coast of Los Angeles, a hollow concrete sphere the size of a small house will soon sit anchored to the seabed. When the grid needs power, a valve opens, ...

Engineers have created a 'supercapacitor' made of ancient, abundant materials, that can store large amounts of energy. Made of just cement, water, and carbon black (which resembles powdered charcoal), ...

Sodium-ion batteries offer multiple advantages over their lithium-ion cousins. Energy storage, however, isn't one of them. That might be set to change thanks to a new method of creating the batteries ...

Researchers at the University of California, Santa Barbara developed a "rechargeable solar battery" that stores sunlight ...

The rapid buildout of wind and solar power generation has set off a race for experimental technologies to capture and store that energy. Several startups in Houston say they’ve developed ways to cache ...

US startups are developing pressurized water storage systems using hydraulic fracturing technology to store renewable energy from solar and wind. This technology offers a potential alternative to ...

The differences in how land and water absorb, store and move energy play a major role in shaping our weather and climate.

Scientists at UC Santa Barbara have created a remarkable new material that works like a “rechargeable solar battery,” storing ...

Ever since Benjamin Franklin’s lightning experiment in the 18th century, civilization has been intrigued by the idea of capturing lightning in a bottle. Over time, however, the idea evolved from ...

Solar panels and wind turbines give the world bountiful energy—but come with a conundrum. When it’s sunny and windy out, these renewables can produce more electricity than is actually needed at the ...
