Interesting new development, with hydrogen fuel cells and the supposedly safer storage of the H2 gas.
'Bath sponge' breakthrough could boost cleaner cars @ BBC, 4/18/20.
After reading this, I seem to recall that the Hindenberg (Zeppelin) was full of hydrogen and had an aluminum- and iron oxide-based paint on the skin that turned out to be highly reactive. Certain rocket fuels also apparently have powdered aluminum in the fuel mix (when mixed with an oxidizer it can be highly reactive). And, wasn't it Apollo 1 where high pressures and the aluminum present in the capsule raised the risk of fire breaking out?
Nice advance in the tech, assuming they've worked through all the little problems of incorrectly bringing aluminum and hydrogen together.
Imagine ... more-cheaply and safely storing H2 onboard moving vehicles. Now, if they can just crack the problem of producing enough of the stuff to matter.

A new material developed, by scientists could give a significant boost to a new generation of hydrogen-powered cars.
Like a bath sponge, the product is able to hold and release large quantities of the gas at lower pressure and cost.
Made up of billions of tiny pores, a single gram of the new aluminium-based material has a surface area the size of a football pitch.
The authors say it can store the large volume of gas needed for practical travel without needing expensive tanks.
