Compressed air is critical in many industrial and nonindustrial applications, including powering pneumatic tools and conveyor systems, cleaning equipment and airfilling amusement park objects. While ...

A grid that runs mostly on wind and solar, part of the future that clean energy advocates are working toward, will need lots of long-duration energy storage to get through the dark of night and cloudy ...

California is set to be home to two new compressed-air energy storage facilities – each claiming the crown for the world’s largest non-hydro energy storage system. Developed by Hydrostor, the ...

In a disused mine-site cavern in the Australian outback, a 200 MW/1,600 MWh compressed air energy storage project is being developed by Canadian company Hydrostor. The facility came about after a deal ...

Two new compressed air storage plants will soon rival the world’s largest non-hydroelectric facilities and hold up to 10 gigawatt hours of energy. But what is advanced compressed air energy storage (A ...

California is exploring a unique type of battery to help power the clean energy revolution: compressed air batteries. This underground $1 billion battery is a giant, clean energy generator that could ...

Scientists in Poland have developed a compressed air energy storage technology using a thermal energy storage (TES) system built into a disused mine shaft. The system works without external heat ...

Broken Hill's hard-rock geology could hold part of the solution to Australia's energy storage problem as the country shifts to renewables. A 200-megawatt, $1 billion facility built by Canadian company ...

Seamus Garvey is the Founding Chairman of the newly established International CAES Alliance, which aims to raise awareness of the potential and power of CAES. Electricity generated by fossil fuels is ...

Compressed air is vitally important to all power plants. Although in some cases it is used simply for convenience, such as when operating certain pneumatic tools, in other cases, compressed air is ...

A Canadian company called Hydrostor has a new compressed-air energy storage system that it says is half the cost of grid-scale batteries and on par with adding a new natural gas plant to a grid. The ...
