Grid storageClimate concerns continue to increase the emphasis on renewable energy like wind and solar. Grid storage is essential for an electric utility to maximize the use of energy from those sources. The Vanadium redox battery seems to be the best to meet the challenges of large grid scale storage. VRB is in an ideal position if they can develop and finalize the needed partnerships. Seems they are well on the way to doing just that. I for one wish them well and see a bright future for VRB shareholders..
