tried to buy some flow batteries a few years ago for a 1mwh battery system. i couldn't find any company that could provide a reference for an actual real customer. lots of vaporware and "we actually installed this only once and no you can't have a reference" companies out there.

If you want to buy today - ESS and Redflow selling today, plus some others

i spent a lot of time with both those vendors as recently as 2021. ESS couldn't give me a real customer reference and redflow's business is collapsing. they did $2.2 million in sales for 2021 and they dropped to $1.6 in sales in 2022.
