Gravity-based energy storage technology company Energy Vault has formed a strategic partnership with non-ferrous metals smelting and refinery company Korea Zinc, including a US$50 million investment commitment. 

Vanadium flow batteries are considered a leading light of the push towards technologies that can meet the need for long-duration energy storage. Not least of all by the companies that mine the metal from the ground. Andy Colthorpe learns how two primary vanadium producers increasingly view flow batteries as an exciting opportunity in the energy transition space.

Chinese companies CATL and KSTAR have begun supplying ‘all-in-one’ single phase residential energy storage solutions in Europe, kicking off with the market for home storage in the Netherlands.

When most people think of the metals that power today’s energy storage systems, vanadium and lithium are at front of mind. Ron MacDonald, president and CEO of Zinc8, argues the case for another metal playing an important role.

First developed by NASA, flow batteries are a potential answer to storing solar – and wind – for eight to 10 hours, far beyond what is commonly achieved today with lithium-ion. In the second of a two-part special report, Andy Colthorpe dives deeper into questions of bankability, market segmentation and manufacturing strategies with four very different providers of flow energy storage technology.
