Reply to comment by [deleted] in The US's largest ever combined wind+solar/battery electricity plant has opened in Oregon with a generating/storage capacity of 350MW/120MWh by lughnasadh

So why bother with batteries at all? hydrogen storage, conversion between states, and gas delivery systems are all made exponentially trickier by the small size of the molecules. That's not to say it can't be done but it isn't done currently at scale.

Yeah I think that operations on the grid aren't microsecond time sensitive. There is absolutely no way to predict usage with that granularity. Even then if that is what you are looking for it would make more sense for the batteries to back stop the hydrogen plant rather than the windmills.

This might explain why. It's a good little article and explains well the nuances of hydrogen. Hydrogen It's a short read, but highly informative.

I wonder why the hydrogen economy doesn't exist? Hydrogen wasn't just invented.

Because much of the infrastructure isn't there or it hasn't been modified to support hydrogen. There will definitely be a hydrogen economy in the future, but that's still in the future.

Renewables need to be funded and built, investments need to be redirected into emerging technologies necessary for the production, transportation and use of hydrogen, e.g., electrolyzers, hydrogen turbines, fuel cells, hydrogen storage, subsidies and policies need to be created to make hydrogen appealing to hard-to-decarbonise industries.

I think everyone understands that a hydrogen economy will have to emerge very soon, but this is a thing with a lot of moving parts, so it's going to take a lot of effort (& money) to make it happen. There are also uses, for which hydrogen will simply not be feasible anytime soon, so other approaches will have to be pursued (e.g. heating and light vehicles).

Oh well if everyone understands it I feel like a real dunce. Keep dreaming you dreams little buddy.
