"H2 pellets" could be the name of a street drug that makes people believe absurd things. But, unless you live on Neptune, it is certainly not an effective form of energy distribution.
Hydrogen solidifies at an insanely low 14 Kelvin. Using an ideal Linde liquefaction cycle will waste you 30% of the energy contained in the fuel simply to perform this deep freeze. You get a relatively low density fuel, about 5 times less energy dense than gasoline, that you will need to protect with massive thermal insulation (think Space Shuttle external tank) otherwise it will outgas like crazy and be an imminent explosion risk. When you add the electrolysis and fuel cell loses, you get a bulky but inefficient vehicle.
Sorry, this will never happen, regardless of what some hard SF author converted to futurologist may have led you to believe.

- yholio 5y agoThere is nothing in your link about "pellets". I clearly assumed you were talking about frozen H2 since this is the standard term in the energy industry, see for example fusion research where solid fuel pellets are used. High absorbency materials have been around for a while, but they failed commercially, they are typically more trouble then the equivalent high pressure COPV tank. Maybe a hype laden Wordpress template website will change it, but I wouldn't hold my breath.
- specialist 5y agoOk, good. Upgraded from impossible to impractical. Progress! In two more days, you'll think it was your idea. What else am I wrong about?
