Interesting article. They clearly make the point that the main problem for flow batteries is the lack of confidence in the market in the technology, which flow technology is going to be the winner and therefor in the prospect of this company going to be around in 10 years time.

What RFX need is substantial capital so they can lease small grid scale storage for solar for small towns and facilities in remote locations.
Think electricity for villages in the South Pacific. Take the technology risk out of the purchase by leasing the battery farm to them. With a bit of initiative, they could structure a capital raising so that the people who fund the capital, get a priority return from the rental paid for the battery farm.

With a few dozen facilities in play, the company has substance, a guaranteed income and the ability to prove the performance of the batteries. Once proven, sell of the farms and income stream to repay the investors and fund the next serious round of expansion after they have the attention of the market.

There were many payment gateway startups - but when PayPal got going the market backed them and the other startup disappeared. Some people in RFX need to think outside the square else this will be another promising technology/niche play that gets left behind when smarter operators make it happen and corner their market.
