Startup wants to build air-based battery & sink it in sea, here’s why [Video]

BaroMar, an Israel-based startup, has ambitious plans to use compressed air as a long-term energy storage solution that could deliver grid-level storage at cost-effective rates. To test out its technology, the company is building a four-megawatt-hour (MWh) pilot project in Cyprus and will store this air on the sea bed, the company said. 

With renewable energy projects involving wind and solar technologies kicking off on a large scale, companies are working to deliver reliable energy storage solutions that can work over longer durations. 

Lithium-ion batteries, which work great for applications like electronic devices and even electric cars, fall short in large-scale energy storage. Not only is the infrastructure expensive to install, but the systems also suffer from issues like loss of charge and deterioration …
