> anything involving electrolyzers is likely wasteful
I've seen this stated a few times in this thread, but read elsewhere that electrolysis of water currently has nearly identical efficiency to steam reforming of natural gas, in the 70-80% range, with a theoretical max that is significantly higher than for the steam reforming process. Factor in the huge CO2 expense of extracting hydrogen from fossil fuels and the ever-increasing abundance of cheap green electricity, and electrolysis looks like the right place to focus to me.
