We already transport electricity and then it is just wasted because we don't need that much of it during peak green energy generation.

There are 2 types of waste, one where prices are negative. These are is best captured by efficient storage, like EV and pumped hydro NOT inefficient hydrogen. Long term, if there is a huge excess of electricity for long periods of time, then investment in hydrogen equipment may be economical.

The second type is from grid congestion. Here hydrogen production has a role because it can be co-located

You would use this otherwise wasted energy and store it in hydrogen.

Better to invest in batteries than electrolyzers.

We're already transporting and storing hydrogen in liquid form without any issues.

There is the issue of needing, for equivalent energy, 30 tube trailers of hydrogen to replace one tanker of diesel. Extending the electricity grid is a better option than building hydrogen pipelines.

You have to realize just how idiotic the idea of a battery trailer is.

Hydrogen energy per volume is equivalent to an EV battery, and volume is what is most important in transportation.

It doesn't matter how inefficient hydrogen is to produce because we'd be using energy that is currently just wasted.

First you need to invest in hydrogen electrolysis, large scale storage, transport and a fleet of hydrogen vehicles and stations.

Or avoid all that expense and just use batteries.
