Flow battery maker Invinity Energy Systems’ CEO Larry Zulch unveiled the first image of its next-generation product at IFBF 2023. It has code-named it Mistral.
Details are under wraps but it will be some 60% more energy dense than the current battery line-up, significantly more efficient and have a levelised cost of energy of $0.06–7 per KWh. It will start shipping from 2024, the company said.
“We think it will be the lowest levelised cost of storage in the market,” said Invinity spokesperson Joe Worthington.
Each of Mistral’s vanadium flow battery modules is identical and the size of a 20-foot shipping container.
On the sidelines of the conference, Zulch told BEST that Invinity was “in deep conversations” with a number of commercial energy customers for new flow battery orders due to be announced from July onwards.
Worthington confirmed to BEST that it had in fact 40 MWh of contracts in final signing stage with a number of customers. He said pilot project deals will be announced in July–August–September.
In April, Invinity said it won match funding from the UK government to build what it called “the largest grid-scale battery ever manufactured in the UK”.
It said the Vanadium Flow Battery Longer Duration Energy Asset Demonstrator (VFB LEAD) project will see a 30 MWh Invinity VFB system deployed at a key node on the UK’s National Grid.
