I feel the same way. Hydrogen takes a lot of effort to store compared to a compound like diesel or even gasoline which can be stored in a (mostly) unpressurized tank.
TFA has me wondering a number of points:
1: What is the energy density of this fuel compared to diesel or gasoline. Is it as dense as diesel, or is it about half to 3/4 as much, like ethanol?
2: How easy is it to have a fuel cell use it, as opposed to direct combustion?
3: How toxic is it? Ethanol is arguably the least toxic, but one atom away is methanol which will cause blindness.
4: How flammable is it? Diesel is flammable, but gasoline not just has liquid, but gasoline vapors give a risk of explosion.
5: Is the process to make it encumbered in patents, or will there be some help to provide the initial impetus to make a working infrastructure to get vehicles to take this fuel?
6: Is it bad for the environment if spilled? Propane if spilled will eventually disperse in the air (or go boom). Gasoline and diesel spills make Superfund sites.
7: What catalysts are needed?
8: How much retrofitting does an existing engine take? Here in the US, newer diesel engines only go up to B5 because any more biodiesel hoses the DPF.
Of course, assuming the best, this fuel would be useful assuming an energy density of existing diesel, but there are just a lot of questions to be asked first.
