Only 1% from water electrolysis, the rest is from steam-methane-reformation (SMR) (i.e. fossil fuels)
“There will not be a single solitary drivetrain technology: Executives project a similar split by 2040 for BEVs (26%), FCEVs (25%), ICEs (25%) and hybrids (24%)” - KPMG Global Automotive Executive Survey
For more than 80 years hydrogen has been produced and used for commercial and industrial purposes and over the last 60 years for space flight.
Today over 10 million metric tons are produced in North America annually. In its liquid form, around 70 million gallons are transported on our highways every year.
Hydrogen, like the fuels we use today, can pose a hazard however, due to how light hydrogen gas is and how quickly it disperses in air it is difficult to ignite.
When compared to other fuels that we use and are comfortable with today such as gasoline, diesel, propane or natural gas, it is as safe if not safer.
Hydrogen is the most abundant element in the universe, but it does not occur naturally. In order to generate hydrogen it must be removed from other molecules. The most common method is steam-methane-reformation (SMR) whereby the hydrogen is stripped off of natural gas and the remaing carbon dioxide is released to the atmosphere.
