EnerVault Corp. announced the completion of a $15.5 million Series B financing, bringing total funding to date to $24.5 million. The company’s investors include Mitsui Global Investment (MGI), Total Energy Ventures (affiliate of French oil & gas major Total), 3M Company, TEL Venture Capital (the U.S. investment arm of Tokyo Electron), Commercial Energy of California, Oceanshore Ventures and US Invest, LLC. The investor funds complement the company’s grant awards totaling $5.5 million from the U.S. Department of Energy (DOE), California Energy Commission (CEC) and New York State Energy Research and Development Authority (NYSERDA). EnerVault is developing energy storage systems based on a novel redox flow battery technology.
"Redox flow batteries are creating a new paradigm for grid-scale energy storage," said Richard See, Investment Partner at MGI. "Because you scale the power independently of energy storage capacity, you can tailor the system to the needs of the application. EnerVault’s approach expands upon the fundamental configuring and sizing benefits of flow batteries to yield the best approach for utility-scale electricity. The more energy needed, the lower the costs, so it’s ideally suited for a number of situations where more than an hour or two of storage is needed."
