“That’s not true at all, electrolysis isn’t usually used for industrial scale production of hydrogen”
Well, not to be argumentative, or as we say in Texas start a p!$$ing contest, as this topic is not in my wheelhouse for sure. But, I’ve been reading articles about hydrogen powered cars for several years and those who mention by products or expellants mention water.
While burning hydrogen produces water, that doesn’t restrict the source of the hydrogen to being produced from water. A number of processes can separate hydrogen from hydrocarbons.
“I’ve been reading articles about hydrogen powered cars for several years and those who mention by products or expellants mention water.”
I guess you shouldn’t be too surprised at low quality journalism and outright lying by environmentalists.
The most common and cheapest method of hydrogen production (steam reforming with fossil fuels) has byproducts including CO, CO2 and other greenhouse gases.
One ton of hydrogen produced will also produce 9 to 12 tons of CO2.
