HYDROGEN - the clean fuel

Hydrogen is one of the most abundant substances in the universe. It is also an incredibly powerful, energy dense fuel. A gallon of hydrogen contains three times the energy content as a gallon of gasoline. That’s why it’s been used as rocket fuel since the earliest days of the Space Age.

Hydrogen is a clean fuel, too. Water is the only by-product of the hydrogen combustion process.

At a glance, hydrogen seems like the perfect fuel for a modern, transportation-dependent society threatened by climate change.

But there are significant problems with hydrogen, as well.

It’s a very expensive, and energy-intensive fuel to produce in large quantities. It’s also unsafe. The fuel is so volatile that it can ignite, without a spark, at much lower air temperatures than fossil fuels. It’s also odorless and colorless. When ignited, it burns with an intense blue flame that cannot be seen in daylight.

Obviously, those realities also make hydrogen a difficult fuel to store, transport and carry on vehicles.

But those hurdles notwithstanding, there is widespread hope that hydrogen will prove to be the Holy Grail for modern transportation systems. Work is being carried out all over the world now to find ways to make hydrogen safe and reliable to use in everything from container ships, aircraft, passenger cars and – yes – trucks.

Back in the 50's AC had their fuel cell tractor which produced around 25 HP and around 1999 the place I worked was making fuel cell plates for a GM design they acquired from AC which amounted to a small suitcase sized unit making 180 HP .
 The part was rather than using it to power reciprocating engine it produced electric to run motors . It seems in above article it shows diesel type engine running Hydrogen fuel and Honda using a fuel cell  - 2 different uses and same outcome - POWER . Both without the weight of batteries which we are told is the ULTIMATE Solution to ban the engines that have powered transportation over last 100 years 

Hyundai / Kia have been working on a hydrogen engine.

As each NEW idea is presented , the nay-sayers have many ideas of how it's bad .
Can one imaging FIRE when individuals cam in contact the first time , heat , light , and BURN .
Steam , from simple seeing it rise above water over fire , to a container building pressure , to heat transfer , steam piston producing rotary motion or mechanical energy , to blowing up a building , boat or closed vessel containing it .
  Then electric where Edison electrocuted a elephant to show DC was safe and AC dangerous . 
  But guess we can blame the Chinese for developing a material that expanded into a gas - fireworks and later gun powder for all the problems it's caused in history since invented . 

Seeing as Hyundai can't seem to keep a/c refrigerant contained, should we expect a more successful effort with high pressure hydrogen?

There are a lot of Youtube video's of people who can't figure out how to put gas in their Tesla, image them trying to refuel it with hydrogen.

Why this one sticks in my mind  I don't know.  Farm Show magazine had retired guy in the early 1980's in Ok that was making hydrogen from a windmill on his farm pond. Getting enough to putt around his property, maybe drive to town in his old ranch pickup.
