An agreement to support the manufacture and sale of vanadium flow batteries has been struck between Australian Vanadium and Enerox, which makes and markets systems under its CellCube brand.

Agreements to deploy 1GWh of novel aqueous zinc battery energy storage in Texas and 500MWh in California have been struck by technology provider Eos Energy Storage, marking a massive scale-up in expected installations for the systems.

News in brief from around the world in energy storage.

The US national Energy Storage Association (ESA) has adopted a goal for the deployment of 100GW of new energy storage using a range of technologies by 2030, updating a previously set 35GW by 2025 target.

“Solar-charged batteries” can help solve California’s energy shortage, with energy storage already playing a small but active role in mitigating the struggle to meet peak energy demand, according to the leadership of two trade associations based in the US state.

A selection of video replays from the Energy Storage Digital Series, hosted earlier this year by Energy-Storage.news’ publisher Solar Media are available on YouTube and have been compiled into a handy playlist.

There’s a race to develop new technologies – and adapt existing ones – that can either be complementary to lithium batteries, or even compete with them. Representatives from three technology providers offer up some case studies, data, insights and opinions on where they think the market could go.

Germany company Voltstorage, claiming to be the only developer and maker of home solar energy storage systems using vanadium flow batteries, raised €6 million (US$7.1 million) in July.

Long duration energy storage is “essential” to help accelerate renewable deployment, according to the US Department of Energy’s Dr Imre Gyuk, who moderates this panel discussion with Matt Harper from flow battery provider Invinity Energy Systems and Russ Weed from gravity energy storage company ARES.

Zinc-based battery energy storage manufacturer Eos Energy Storage has signed an agreement with an EPC partner to deploy systems based on its devices at rural microgrids, beginning with projects in Nigeria.
