Affordable and reliable energy storage is the holy grail of clean energy. With the variability of wind and solar, their increasingly low costs and the desire to have a renewably powered world, the drive for cost-effective storage is tremendous.   E-stone Batteries is developing a long-life, low-cost, non-toxic battery that is made from abundant and widely available minerals. We are working on a re-invention of Edison’s old Nickel-Iron Battery and are now set to create a battery that spurs realization of a future clean energy supply.
