Despite this, rival research firm Navigant found that in 'non-lithium niches', flow batteries are leading the way, taking about 5% of the global energy storage market share and second only to lithium in that respect – while lithium-ion comprises almost 95% of the remainder. Robert F. Kennedy, Jr, board of Directors at Vionx, said the project for Holy Name was a "breath-taking solution" and "game changer", adding, "The consequences of that new reality cannot be understated". Among the handful of vanadium redox flow energy storage system manufacturers operating today, with others including Primus Power, VIZn Energy, Redflow, Sumitomo, Rongke Power and Redt, VIONX has been among the more successful in attracting investment funding – the company netted US$12.75 million in venture capital (VC) funding in the second quarter of 2017 and raised US$58 million during 2015, according to reports from clean energy financial market tracker Mercom Capital.
