Wind and solar power are now the lowest cost of new energy around the world. Long duration storage of 6-hours or more is needed to balance the intermittency of these resources.
VRB-ESS® store energy in liquid electrolyte in a patented process based on the reduction and oxidation of ionic forms of vanadium that is safe, reliable and non-toxic.
Rated for over 100,000 cycles at full depth-of-discharge, this battery does not wear out like lithium and lead-acid.
