Ever see an explosion resulting from a hydrogen leak?
I have, and it was only “minor”. Lofted a 400 lb. retort cover 40 feet up until it hit the roof supports, and bent them about 6 inches. It missed the furnace operator when it came back down, thankfully.
If a neighbor started parking a hydrogen car in his garage, I’d sell up and move ASAP.
Almost all Walmat and Amazon massive warehouses use 100% hydrogen powered lift trucks. No downtime compared to batteries, and cleaner than propane. Amazon has been using hydrogen lift trucks for almost a decade, no explosions.
Hydrogen has and will expand its niche. But I doubt we will see it on a domestic vehicle scale
