Honestly, this is not as crazy an idea as it seems at first blush.
This essentially solves the distribution and storage pitfalls of hydrogen but only partially solves the economics of hydrogen production.
Great idea. We could land at night when it isn’t so hot and bright.
How is she in any way qualified to be the energy secretary? Just her ideology, I guess.
Don’t tell me what you are going to do in 10 years. Tell me what you will be doing in fours years at the most. As far as I am concerned, any promises made by a politician that will happen after they are out of office is worthless.
Equip every vehicle, especially first responder vehicles, with a broom so they can detect a hydrogen fire.

A Harvard lawyer, aren’t they qualified for everything ?
There is a light responsive thin-film hydride material which in current market form, stores a half kilogram H2 in twenty pounds of storage device at zero pressure.
A kilogram of H2 is close to triple the energy content of equal weight of gasoline, and run through a fuel cell to drive electric propulsion, would give three times the range of an internal combustion drivetrain.
I'll take "octane" for $2,000, Alex.
Amorphous sputter-deposited alumina works better.
Artificial. Lowering the cost means pumping in taxpayer funds.
Like using channel locks to open the petals on a rose.
To make hydrogen “affordable”, you manipulate the supply of other forms of energy to make them excessively expensive so that hydrogen “seems” affordable.
Yes but it does not allow for movement, or connections like you would use in a vehicle.
This is what happens when your only engineering credential says woke on it
Wow, that’s the ticket. Get the price down less than bottled water, and water falls from the sky...
Toyota has a hydrogen powered car which stores it’s hydrogen in a 70MPa/10,000PSI tank. They have a functional system in place for refueling the vehicles.
A new technology under initial development with DOE since 2009 binds hydrogen to a nano-patterned magnesium alloy (hydride) film. There is no gas pressure inherent in the medium in storage mode. A ribbon of this storage medium passes through a laser scanning system to liberate the hydrogen as gas for immediate use upon a demand basis.

At 10000 psi, you wouldn’t even need to burn the hydrogen;)
So how much energy does it take to compress hydrogen to 10,000psi equivalent to 20 gals of gasoline?
Your physics teacher failed you and for that they should be ashamed.

H2 has one of the highest LHV per kg of mass than virtually any other fuel. LHV is in a standard atmosphere of N2 and O2 btw.
H2 is 119.96MJ/Kg
Conventional petrol is 43.44MJ/Kg

The biggest problem with H2 is leaks!
The molecule is so small, leaks are common, hard to find and maintain.
Probably not something you want in an car with all the vibration.”
Don’t tell this to Exxon or Valero they use pure hydrogen gas by the millions of kilograms per year at every oil refinery they run. Some how that figured out how to contain this devil of a gas while using it at thousands of psi and 800 plus degree temps. Aluminum , Teflon, austenitic stainless I could go on and on needless to say the issue has been solved decades ago but luddites gonna ludd I guess.
