"90 percent hydrogen with an improved efficiency of over 26 percent." Lets see a diesel Cummins Ram would get 25/31 mpg (vs 20/25). Fuel costs $16/gallon hydrogen,$6/gallon diesel so $14.40 + $0.60 = $15 gallon.

hydro-diesel: $0.48-$0.60/mile. diesel: $0.24-0.30/mile

I don't see this being viable without a significant cost reduction in hydrogen, also the storage of the hydrogen is also a problem. If this was a supplemental fuel like a NOS canister, I could see that doing something.
