How advanced is the hydrogen production prototype?
Looking at the Wikipedia page https://en.wikipedia.org/wiki/Steam_reforming this looks like a difficult process, even when using methane that is a very small molecule and is easy to purify. Big molecules in grass are more eager to produce soot that would block the machine, and grass also has other elements like Nitrogen and Phosphorus that may react with the catalyzer, and there is the ash problem.
Is using a grass more efficient that burning the grass and use the energy to produce Hydrogen with the standard method?
What about producing ethanol from the grass and then using the ethanol to make the Hydrogen? (Both parts are somewhat proven technology.) And ethanol is easy to move and purify than grass.
