Amazon plans to make its own hydrogen to power vehicles (www.theverge.com)

Amazon thinks hydrogen can be a more sustainable fuel for vehicles at its warehouses, but it’ll have to clean up hydrogen production first.

It's not even is the same ballpark as dc batteries. Charging a battery is 93-97% efficient as is the use of that power so overall efficiency stays above 90%. Hydrogen average 40-60% overall efficiency. It ONLY makes sense when using 100% renewable.

Especially in situations where it's otherwise wasted. California has been curtailing massive amounts of solar each year, dumping the extra into hydrogen would be amazing

That's where nuclear can shine as well, make hydrogen during off-peak hours
