That's how long it has been since PNNL licensed their technology to Uni Energy Systems. Y hey have come a long way since then. The VRFB has transformed many parts of California ,and other western and eastern states. Slow downs happen of course,due to "unforeseen" situations. None the less,the VRFB will be making history again, repeating its entry into other countries. This is a win-win program for today,and years to come.
