better way since the 1980s

New iron catalyst could - finally! - make hydrogen fuel cells
affordable
For decades, scientists have been searching for a catalyst that
dramatically reduces the cost of fabricating hydrogen fuel cells.
...
...
In a study published Thursday (July 7) in Nature Energy, scientists
describe how iron can be combined with nitrogen and carbon to produce
a catalyst that is efficient, durable and inexpensive - the three main objectives the U.S. Department of Energy (DOE) has identified for fuel
cell research.

Hydrogen ICEs do work, but I'm not aware of them being sold.
Japan may have a hydrogen "economy" in the future.
====================
Hydrogen is developing fast in Japan, edging nearer to wider use in
society
Apr 10, 2024
Japan is a global leader in hydrogen technology development, largely
due to its strategic emphasis on hydrogen as a next-generation energy
source.
Japanese companies are pioneering the application of hydrogen
technology across various sectors, including steelmaking.
Despite the optimistic outlook and advancements, Japan, like the rest
of the world, faces challenges in making hydrogen energy economically
viable.

How do you store it safely at scale?

The "could" word has been used for some 40 years....I'm waiting for
the "will" word.
If a catalyst can be found to do hydrolysis cheaply, I would expect a world-wide hydrogen based usage for vehicles/etc.

Long term storage of hydrogen is difficult.

Presently available storage options typically require large-volume
systems that store hydrogen in gaseous form. This is less of an issue
for stationary applications, where the footprint of compressed gas
tanks may be less critical.

Problematic for moving it around though, and having it
move around.

Now compare that with electric.
electric is "the truth"
