So, the article commits a pretty large error by describing this as the cheapest energy storage. This advance, even if we take a corporate press release at face value, only brings the cost down the the level of compressed gas storage. It's cheaper than lithium-ion but battery storage project costs, like most other utility projects, are dominated by infrastructure, land, regulatory costs, inverters, etc.
