Augwind Energy, based in Israel, will build the “world’s first commercial-scale AirBattery system” in Germany. The battery will use compressed air stored in salt caverns to generate electricity. The AirBattery system can store enough compressed air to generate gigawatt-hours of electricity. The air is compressed using excess renewable electricity and … [continued]
A research team at Penn State University indicates that geothermal energy supports the case for repurposing abandoned oil and gas wells as long duration, compressed air energy storage systems for wind and solar power.
Whether it’s a malicious authoritarian plot or plain old bureaucratic bungling, President Trump has compromised air safety, public health, and national security, and capitulated to Russia, all within his first 30 days in office. That’s just the short list, and the hurts keep on coming. Nevertheless, clean energy investors still … [continued]
China is leading the development of compressed air energy storage with many new techniques it has recently perfected.
A new analysis indicates that compressed air energy storage systems can beat lithium-ion batteries on capex for long duration applications.
The other day, I published my doorstop assessment of the thermodynamics and operational challenges that limit compressed gas storage solutions, pushing them into the 100 GW of also-ran capacities. In comments in various places, people reminded me of the long-defunct LightSail and the now-getting-press Hydrostor. A bit of followup with … [continued]
New long duration, large scale compressed air energy storage system leverages simple water pressure to cut costs.
Texas continues to rack up the renewable energy wins with a record-breaking month for solar power capping a surge past coal.
Assessment Shows Global Warming Potential Lowest Among Technologies Studied
In a recent article, we found that curtailment of renewables may be cheaper than grid scale energy storage. Sometimes, the simplest solution is the best solution. However, given the complexity of electrical grids around the world, we should also look at all of the available solutions to make sure we … [continued]
