“This system demonstrates remarkable efficiency in storing solar energy as electrons,” the study authors said. This work shows that solar energy can be captured, stored, transported as a liquid, and ...

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 ...

KEY POINTS One of the longest-duration pumped storage hydropower projects in the country is proposed for Navajo Nation land in the Four Corners region. The project received a $7.1 million Department ...

ELY, Nevada—The smell of piñon pine filled the air as the Ghost Train of Old Ely rolled to a stop between the Duck Creek Range and another railway. Two peaks of jagged limestone towered above the ...

For years, the solar energy sector has grappled with interseasonal energy storage. The ability to harness the surplus solar energy of summer months for use during the winter has remained an elusive ...

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 ...

In an effort to reduce the use of precious land to build renewable energy storage facilities, the Fraunhofer Institute has been cooking up a wild but plausible idea: dropping concrete storage spheres ...

Water and energy in buildings are intertwined, not only at the point of consumption, but also at the point of generation. Four percent of electricity use in the U.S., or 75 billion kWh annually, is ...

Energy Vault's EVu concept is a superstructure tower design, which improves unit economics and enables GESS integration into tall building. SOM will work on systems for actual projects with customer ...
