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
Better to invest in batteries than electrolyzers.
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.

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