Back in early January, I mentioned it was bad news that VRB, the makers of large-scale, long-lasting vanadium flow batteries for storing electricity, was going out of business.

Well their assets have been acquired by Prudent Energy, a wholly-owned subsidiary of the Chinese JD Holdings Inc. This is good news in the sense the Prudent Energy is already involved in developing vanadium based flow batteries. They have no incentive to sit on the patents. So the technology will continue to get its shot in the market.

Grist thanks its sponsors. Become one.
