1. Low Cost: Building on over a hundred years' experience with the most widely used form of energy storage means low risk and an established industry to leverage deployment. Being 2.5x smaller, by volume, means dramatically lower construction costs, faster build times, easier reinstatement and easier landscaping. 2. Agile: By innovating in the high-density fluid (R-19 TM) we use, we unlock many hundreds of times more suitable sites. Projects can be installed on hills 2.5x lower than a project using water and still achieve the same power – for example there are so many more hills at 150m than at 375m. 3. Clean: Our innovative fluid R-19 TM is environmentally benign and has been engineered to be non-reactive and non-corrosive. Our plants require smaller footprint and have minimal recyclability and supply chain considerations.
