Steve - It's not the technology. We know that hydrogen works.
It's the economics. A key metric in FID is ROI. In today's world it is pretty difficult to produce a major capital project for Hydrogen that has a positive ROI or a payback in less than 10 years.
Smart companies like Exxon, Woodside, APD and Linde have all run their financial models and the economics look pretty discouraging. What concerns me is that PLUG doesn't seem to worry about RAROCE or ROI.
