Substance Power and Mobility seeks to anticipate the impending convergence of three technologies: On-site Solar, Energy Storage, and Electrically-driven Transportation Solutions. With this in mind, we have engineered a, patent pending, energy storage technology to harness the power of solar in commercial and industrial buildings. Our technology does not only promise to store energy from on-site generation sources but, also, to allow the fleet operator to deploy the same energy storage devices deployed in the building, aboard the last-mile delivery solutions. This multi-use strategy will reduce initial cost for energy storage in buildings as well as on-board transportation solutions.
