I've dreamed of using existing natural gas pipeline infrastructure to pipe H from renewable resources around for building heating for a decade. Hope the US does it and would be equally glad, maybe gladder considering the US headstart, if someone else gets there first.

Storing and transporting hydrogen is inefficient and nontrivial. This article glosses over this.

It makes more sense to convert the hydrogen to methane after it's produced for storage and transport.

There are as many impurities as things happened on June 4th 1989 on Tiananmen Square 😉

They could reach this level of purity by sending all impurities to re-education camps. /s

This is fake news. Stop spreading lies.
