Energy storage company Invinity Energy Systems has launched its next-generation vanadium flow battery, Endurium.

The technology has no cycle limits, no fire risk, high efficiency and a modular, scalable architecture optimised for large scale projects, according to Invinity.

As the proportion of the world’s energy that is delivered by large-scale solar and wind projects grows, the need for long-duration energy storage (LDES) has become critical.

Endurium is capable of reducing costs and carbon emissions and increasing energy security, while enabling the retirement of ageing fuel-based generation assets and the global transition to 100% renewable power, the company added.

Invinity’s president and chief commercial officer, Matt Harper, said: "Invinity’s mission has long been to build safe, durable batteries that will accelerate the path to net zero by delivering renewable power on demand.

"With Endurium, we now have the product that will achieve that goal.

"Endurium is designed to dispatch renewable-generated power on demand at a lower total cost than any fuel-based conventional form of energy.

"This means homes, businesses and industries worldwide can now be powered by abundant clean energy at the same time as lowering consumer energy costs.

"The Invinity team is thrilled to have achieved this milestone, and we look forward to continuing to play our part in accelerating global progress towards net zero."

First shipments of Endurium will commence before the end of 2024, and confirmed customers include multinational energy equipment supplier Gamesa Electric and Taiwanese energy storage company Everdura, Invinity said.

The technology has also been selected for 84MWh of projects backed by the US Department of Energy, with deliveries to Pacific Northwest National Labs and Dairyland Power Cooperative expected to commence in 2025.

It is also expected to be eligible for support under the LDES Cap & Floor Scheme announced recently by the UK government, according to Invinity.
