Primary vanadium producer Largo Resources has closed a deal to supply its first grid-scale vanadium redox flow battery (VRFB) system.

A cross-border platform is being created in Europe for the provision of secondary reserve to maintain the grid’s operating frequency, which will be open to energy storage in the coming years. Tanguy Poirot, analyst, and Corentin Baschet, head of market analysis at energy storage specialist consultancy Clean Horizon take a deep dive.

Large-scale liquid air energy storage (LAES) systems which can store and discharge energy for up to six hours are being planned in Spain by technology provider Highview Power.

There exists a strong potential for energy storage to provide ancillary services in the Iberian Peninsula’s booming renewables market, but regulatory stability should be provided to encourage the sector’s growth, a panel has suggested.

The results of Spain’s auction last week for 3GW of renewables capacity have been widely welcomed by the country’s solar sector, but calls have been made to tweak future auctions to support smaller-scale projects as well as encourage the participation of bids with energy storage.

Solar PV bidders secured two-thirds of allocated capacity in the first of Spain’s new renewable energy auctions, while energy storage was not included in any of the winning bids.

The first of Spain’s new renewable energy auctions is set to take place next week, as the country offers the possibility for bidders to include energy storage in their offers.

Two UK-based firms, energy supplier OVO Energy and integrated home battery storage provider Social Energy, have expanded into international markets in Spain and in Australia respectively.
