Hi, I am Tobi from south Germany. I have found out about the community by searching Google for information about redox flow batteries.
I need a big capacity energy storage for my current project, an electric self sustaining yacht.
The safety of Flow batteries makes them a very attractive choice to me although I do not know yet if energy density and output might fit my needs. But all of my questions for sure will be answered here 
If you are keen to see the project, you are welcome to visit me at x.com/dreamhydrogen
