From one of the comments on one of the lazar videos:

     Pretty cool stuff. Using a lithium hydride for storage
     is a huge improvement over pressurized/liquified hydrogen
     for storage and transport.

     The drawback is efficiency; it takes a lot more energy to
     separate the hydrogen from oxygen in water than you get back
     by burning the hydrogen. If you take the electricity used to
     separate the hydrogen, and store it in a lithium ion battery
     (for example) you can use an electric motor to run the car
     directly with 80-90% efficiency, and you don't need a particle
     accelerator to generate the hydride (particle accelerators use
     a lot of electricity). The hydrogen powered vehicle only captures
     about 30% of the electrical energy used to capture the hydrogen
     and manufacture the hydride as fuel energy for the vehicle. The
     same electricity used to generate 400 miles of hydrogen range
     would give you 900 miles of battery range if you used it to simply
     charge up a Tesla. The hydrogen-powered car does give you more
     energy-dense fuel storage: the hydride tanks for 400 miles of fuel
     weigh much less than a 400-mile range lithium-ion battery (a Model
     S with a 100 kWH battery pack has a 403 mile range, for example). The
     hydride vehicle is cool, and green, but all-electric battery-operated
     vehicles are more than twice as efficient, which means they cost half
     as much to run in kiloWatts per mile. Who killed the hydrogen car?
     Economics, in the form of cheap lithium ion batteries and efficient
     electric motors."

Boeing and Airbus, realizing that their business models are at risk, given
worldwide goals on reduction of CO2 emissions (a bit more than 2% of CO2
emissions are for air passenger and freight traffic) have been investigating
several possible alternatives, including SAF (Sustainable Aviation Fuel, such
as that made from recycled fats or from agricultural waste feedstocks),
Hydrogen (Liquified or Pressurized H2 Gas either combustion or fuel cell),
Electric (Battery in the 1000 to 2000km range basket) or a recent suggestion
from WPI, a Magnesium Hydride slurry added to JET-A, the Mg binds to CO2
in the atmosphere and precipitates out as MgCO3 or MG(CO3)2; harmless
(and actually edible) capture of the Carbon from the atmosphere making
the flight carbon-negative.  It does still rely on a non-renewable
resource, and the energy costs of creating the MH2 slurry may be prohibitive.
