Toyota builds experimental hydrogen-powered pizza oven and grill.

This is a most excellent place for technology news and articles.
If these are serious concerns for you, I'm sure you will always be able to find plug in electric grills on the market.
I don’t think you really grasp how much pressure 10,000 psi is.
A typical car tire is like 35 psi
A propane tank for a grill is like 200 psi.
Have you ever seen a car tire burst? Or a propane tank? Big booms, they can easily hurt or kill people already.
A hydrogen tank would be 50 times more pressure than a regular tank of fuel, and 300 times more pressure than a tire. If those burst, people will die, and have their bits spread around the neighborhood.
Unfired pressure vessels are already pretty common common in industrial, commercial, healthcare, transport, and recreational settings. I am comfortable with continuing to trust the engineers as the portion of these vessels that contain hydrogen increases.
