I beg to differ. Based on IPs from Columbia Uni, NYC, we are a startup working on technology to produce green hydrogen from sea water and renewable energy. We received a NYSERDA validation grant and are on our way to pilot in the Port of Rotterdam in 2020. We are currently looking into the possibility to crowdfund some of our work.
The way I see it, you're somewhat in a different ballgame since you're not buying explosive/toxic gases from anyone else. You're producing an explosive gas from seawater. Still, I imagine you need some pretty big safety zones if you're operating at scale, no?
