One of the nuke plants I work at put in a hydrogen electrolyzer two years ago for this reason, and they are doubling it's size next year because it worked so well. Their "problem" is different than solar. Nukes constantly put it the same amount of power, so they feed the excess into the electrolyzer when demand is low, but it's basically the same idea. Electrolysis id inefficient, but if you're producing more energy than you can feed into the grid you may as well do something useful with it.

Same reason I think carbon capture is worth looking into. It should not be a primary solution. I know some fossil fuel groups are behind it today. But in the not too distant future we are going to have excess green energy. Capturing carbon is worth seeing if we can scale to the point of being one of our tools. People are quick to scoff at the idea. Much like I've seen with hydrogen. But I'd rather try many options to reverse change that might not be perfect. Instead of hoping we transition power sources and that alone was enough.

The 2 go well together. Hydrocarbons are an excellent carbon store. Carbon also stabilises the hydrogen, so it doesn't leak through the walls of your containers. Lastly, it can actually to replace oil in things like plastic production.

In a pinch, you can also burn the result, to get energy back.

I agree. Carbon capture is not the solution, no one thing is, but it should be one of the many things we use to work toward a solution.
