Whatever happened to hydrolysis ?

Twice as expensive?

Yes, if you don't count the externality.

I've been wondering for 20 years or more what is so difficult about a
real carbon tax. (Ok, there already is one on road fuel). It even seems
like something that you might be able to get international agreement on,
instead of all this pussyfooting around about targets.

Double or triple the cost of coal, oil, and gas and all of a sudden
nuclear and renewables start to make real sense. And you get a strong
incentive for electric commercial as well as private vehicles.
