Greensmith works with a variety of battery chemistries from different vendors, as well as multiple inverters and power electronics partners.Īmongst other technologies, Greensmith is using Aquion Energy's sodium-ion battery. Greensmith has been threatening to deploy four additional battery types since earlier this year.Ĭompanies like the 30-employee Greensmith are winning energy storage projects not because they are building better batteries but because they are writing software that integrates batteries with inverters and allows energy storage to work with the grid at scale. Last week, Greensmith CEO John Jung told Greentech Media that batteries from Aquion (based on an aqueous sodium-ion chemistry), ViZn (zinc redox flow batteries) and two established lithium-ion battery suppliers have been added to the eight battery types already deployed in its systems. The startup is a software developer and system integrator that has attracted investment, personnel and a growing roster of turnkey energy storage projects. As the energy storage market develops and shakes out, it's worth keeping an eye on Greensmith.
