US firm ViZn Energy Systems has headed a ‘top 10 league table’ of alternative lithium-ion battery systems for grid storage drawn up by industry analysts Navigant Research.
Navigant ranked ViZn’s zinc-redox flow battery system as first in its list of “technology alternatives in the best position to capitalise on the numerous weaknesses of Li-ion technology— and capture a piece of the rapidly growing stationary storage industry”.
Sumitomo Electric was the runner-up. Other vendors included in the top 10 were Gildemeister, a subsidiary of German manufacturer DMG Mori Aktiengesellschaft, Eos Energy Storage and Primus Power.
In May, US-based Eos said it was expanding the reach and commercialisation of its Aurora battery technology— a 1MW/4MWh DC battery system employing Eos’ aqueous, zinc-based Znyth technology.
Primus Power announced last summer it had teamed up with a Taiwanese manufacturer to help the march of its flow batteries into China’s energy storage market.
Navigant energy research analyst Alex Eller said: “ViZn’s advantage in this market results from both the advantages of its technology and the ecosystem of partnerships it has developed. The operational flexibility of the company’s technology, combined with the ability to reduce prices using low cost materials, will be key as the market matures.”
