Keith - Note that I did not say "clean" in my writeup. And R&D Magazine only stated that the new system will help the Navy "...transition away from large-battery and fossil fuel technologies..." However, I agree with you that these days most H2 is not produced from renewable energy sources, but from reforming natural gas. This basically includes all the fuel cell refueling stations being demonstrated by Air Liquide, Air Products, Linde, Shell, etc.


I question the claims about clean fuel/energy. What is the source of LOx and H2? Likely electricity, generated by fossil fuel or nuclear. They should tout the energy density and leave the "green" argument out.
