  1. “Hydrogen is not a source of energy, but a storage system” Just like a battery 🔋

  2. “Pressurized hydrogen / Gasoline - 1/6 energy per litre” It is still lighter than battery 🔋 cars

  3.  @OneDayWillFlyAway  - “ammonia? … it is not free” but is cheaper to transport than liquid H2 and can be used in combustion applications without conversion, and can also be used as a feed stock for other industrial applications like fertilizer

  4.  @CritternNation  - “ammonia is extremely poisonous” So is salt, a tablespoon of salt ingested can kill a small child, yet we keep it on our kitchen tables. God forbid you drink too much purified bottled water in one sitting, that will kill you. “one leak and kiss a few 1000 souls goodbye” That’s why we clean our homes with it. NH3 is safely used as a fertilizer & cleaning agents, is the second most transported chemical in the world, naturally occurring NH3 is about equal to manufactured NH3. Combustion results in atmospheric nitrogen & water - it is well understood & handled today.

  5. “Water” Don’t need fresh water for irrigation for producing hydrogen, can use off shore salt water

  6. “Platinum” Catalytic converters currently use it, transitioning to H2 cars will allow the existing platinum production for fuel cells in H2 cars
