...by stupidly adding hydrogen crap to it, since in China, hydrogen is made overwhelmingly by reforming dangerous fossil fuels.
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 approximately 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)

EST: Chinese Hydrogen Production Is Making Climate Change Worse.
The fossil fuel industry loves to advertise hydrogen in order to greenwash itself. We see their ads here all the time. Nevertheless, there is probably no one here who has ever seen a hydrogen bicycle, a hydrogen motor cycle, a hydrogen car, or a hydrogen bus, a hydrogen helicopter and all the other bullshit in these ads.
I haven't, despite being an old man who's listened to hydrogen bullshit for the last 50 years. My own experience with hydrogen is limited using it in organic synthesis. I'd fill the tank every six months. The hydrogen in the tank was clearly made from the reformation of the dangerous fossil fuel natural gas.
