1. That is, of course, the dumbest statement ever produced by antinukes, but not surprising really...

...since they lack the literacy to tell primary energy from derived energy produced by exergy destruction.

It also makes sense because many fossil fuel sales people wish to greenwash coal by claiming it's "hydrogen."

It makes the same sense as it does in China, since Australia is a coal hell as well and they may as well jump on the coal greewashing.

Subsidizing Grid-Based Electrolytic Hydrogen Will Increase Greenhouse Gas Emissions in Coal Dominated Power Systems Liqun Peng, Yang Guo, Shangwei Liu, Gang He, and Denise L. Mauzerall Environmental Science & Technology 2024 58 (12), 5187-5195

The text is clear enough.

From the introductory text:

... Currently, nearly all hydrogen in China is either produced directly from fossil fuels (55% from coal gasification and 14% from steam methane reforming (SMR)) or as a byproduct of petroleum refining (28%), with only 1% coming from water electrolysis. (2) Producing 1 kg of coal- or SMR-based hydrogen emits roughly 19 and 10 kg of CO2, respectively. (3) In 2020, hydrogen production from fossil fuels in China emitted ∼322Tg of CO2, equivalent to 25% of total CO2 emissions from industrial processes, a number expected to rise with increasing hydrogen demand. (4) Industrial processes include production of nonmetallic mineral products, chemical, and metal products, as well as production and consumption of halocarbons and sulfur hexafluoride. (4)

The bold, italics and underlining is mine.
