RE: Long read: Flow batteries scale up to GW production28 Sep 2019 13:47
Thank you @Serenus, indeed a very positive/interesting article, also outlining some of the possible reasons why VRFB take-up has been slower than the technology perhaps merits. Link repeated here:

In terms of the measured longevity of VRFB batteries, it was good to read the following, from Alex Au, CTO of Nextracker: βWe have run a vanadium flow battery through 24,000 hours of very aggressive cycles and still cannot measure any degradation on the batteryβs performance.β
The final section is hugely upbeat, quote:
This is good news for the 70,000-square meter factory taking shape in Saudi Arabia. Its opening in 2020 will deliver over 1 GWh of redox flow storage capacity to the market each year, bringing unprecedented economies of scale to an industry that has so far had to make do with tailor-made solutions as it contends with mass-produced competition.
The Saudi plant will churn out vanadium flow batteries developed by Schmid, a German PV equipment supplier with 150 years of experience in industrial engineering. The family business branched out into redox flow batteries in 2011, commercialized its first vanadium flow battery in 2014, and set out in search of partners to scale up production.
Schmid struck a deal this year with RIWAQ, a Saudi construction firm, and Nusaned Investment, a subsidiary of Saudi petrochemicals giant Sabic, which finances technologies supporting policies set out by Saudi authorities. In 2016, the Kingdom announced its Vision 2030 plan to reduce national dependence on oil revenues, notably through massive investment in renewables. The venture brings together some of the most venerable veterans in the flow battery industry with exceptionally deep pocketed investors. βThe new Schmid deal in Saudi Arabia is very exciting,β said Maria Skyllas-Kazacos, who invented redox flow technology in the 1980s. She adds that the plant βwill definitely help to provide the production scale needed to further reduce costs.β
