The grid can handle overnight charging just fine, there's more than enough transmission and distribution capacity.
Natural gas pipelines can not be used with hydrogen without some as of yet undiscovered coating. Plus these pipelines are single use; are you going to stop all gas usage in all houses before we let people fill up at stations or homes?
We can use exactly zero of the current gas distribution system for hydrogen. Hydrogen molecules are literally the smallest in the universe, we haven't invented a container where they won't escape. You can't just pour hydrogen into a gas station tank or transport it in a natural gas pipe.
Transporting hydrogen will always result in huge losses. Less huge if you transport it as a liquid, but then you need to transport it at -252 Celsius - which brings a whole new set of problems.
My chevy bolt will charge at 8a (conservative) or 12a (“fast”) at my preference. It takes maybe 3-4 hours over night to charge from my average driving day with a decent commute.
My car consumes, while charging for a few hours overnight, about the same amps as a good clothing iron or a beefy vacuum. If i wanted, i could delay charge so three EV charged overnight, never draeing power at the same time.
My next car will buffer power so solar cells can overcharge and supply back to the house. And it will be a backup power supply for storms and grid outages so I no longer need a standby generator.
Tell me again about how the grid isnt ready for my BEVs and why we should be pumping some liquid or gas into tanks?
It is the same reason why we have miles of natural gas pipelines sending NG to local NG turbines instead of a few big NG power plants with wires sending electricity everywhere.
Hydrogen we need to make using a resource intensive process, and it leaks from every single container ever made, because it's literally the smallest molecule in the universe. Hydrogen transport incurs so big losses that it's not feasible at a large scale [0].
To move an equal amount of energy, you need 4x many ships as LNG, because you lose 23% more during transport than LNG AND you need to transport it at -253C which is a whole another issue.
Hydrogen is a good energy storage medium, but it's not practical for transportation. It's a lot easier and cheaper to move the same amount of energy using the power grid.
The future of hydrogen is renewable energy storage, on location. Not transport.

You do not need 4x as many ships. You just need bigger tanks. Hydrogen is much lighter than LNG. Bigger tanks are not an issue. You're hearing straw-engineer arguments from those with a vested interest to BS about these issues.
Why would the World Hydrogen Congress have a "vested interest to BS"?
The speaker is comparing a LNG ship to a prototype Kawasaki LH2 ship, with actual values for both.
What he's suggesting is that we transport ammonia instead of LH2, ammonia is a lot more stable to transport and can be converted to hydrogen at the destination.
Ammonia is an option too. But this does not preclude other ideas.
We have an electrical power grid, dude. And it works just fine for home BEV charging.
What makes you believe the current gas network can be used for Hydrogen? I don't believe this is the case, but would be interested in seeing evidence to the contrary.
