I sure would like the promise to be true but the article reassembles the parts of the technology that skips the realities.
Number 1 is what will be the source for the reduced Hydrogen. (reduce referring to the redox chemical characteristics). You will have to have a separate energy source to secure the Reduced Hydrogen even in a Hydride state. Water is not the energy source for reduced Hydrogen though it is a ready source for the material Hydrogen but in the highly oxidized state. The energy to reduce, split apart water into Oxygen and Hydrogen gas, has to come from something else. Solar, Hydrocarbon, Nuclear?
Number 2 the present Hydride they are compounding as beads that can be "poured" into a car does not meet the Thermodynamics or the rate of Hydrogen delivery to power an internal combustion engine. I think it is more suited to a storage process that can then be used to power fuel cells in production of electricity for electric cars except
Number 3 it isn't presently reversable so that it is a consumable product and therefore will have disposal problems
