I'd like to believe that something like this is possible, but I just don't get how this gets around the fact that every Joule that is used for bitcoin mining is a Joule that wasn't used somewhere else. Even if many Joules of renewable power get wasted during periods of overproduction (mid-day in the summer in California), other more worthwhile loads could be shifted to use that power, because today it's negative-priced during such periods. If bitcoin soaks up that power, it won't be negative-priced, and other loads won't be moved to use it, and they'll use power from non-renewable sources during some other time of day.
There's all sorts of demand shifting that can be done. Most articles talk about washers and dryers, and certainly that's one smaller load, but also EV charging, pre-cooling of buildings during the summer (run the AC in houses full blast during the middle of the day so there's no need to run it in the early evening), etc.
