New vanadium redox flow battery (VRFB) technology from Invinity Energy Systems makes it possible for renewables to replace conventional generation on the grid 24/7, the company has claimed.
Anglo-American flow battery company Invinity launched its new product, Endurium, today. It follows around three years of R&D, testing, and prototyping, during which Invinity has partnered with Siemens Gamesa on technology development.
Designed for high energy throughput with unlimited cycling and with at least a 50% reduction in the footprint required for installation at project sites, the company said it could cost-competitively tackle present-day energy storage markets and emerging long-duration energy storage (LDES) opportunities alike.
The London Stock Exchange-listed technology provider and manufacturer’s chief commercial officer Matt Harper and senior director for corporate affairs Joe Worthington spoke with Energy-Storage.news.
“It’s a huge step forward for us,” Harper said of Endurium’s launch.
“We have always had as sort of our North Star as a business, the desire to be able to take renewables, especially solar power, and deliver it on demand, 24/7 to replace any other form of generation on the grid.”
The capabilities an energy storage technology needs to attain that goal are a combination of long storage durations, high throughput through the battery, longevity, and “ultimately, accountable cost,” the CCO said.
While the fundamental technology, including the vanadium electrolyte chemistry, has not changed bar some incremental improvements, the partnership with renewable engineering specialists Siemens Gamesa has enabled what Harper and Worthington said are significant improvements in the system’s integration.
