With Hydrogen Into The Future
Sponsored By MTU Aero Engines March 31, 2021

Hydrogen has the potential to enable completely emissions-free flight for most aircraft in the future. MTU Aero Engines has high hopes for it. “Hydrogen is a highly attractive future option for us as an aero engine producer,” says MTU Chief Operating Officer Lars Wagner. “It should be used as a fuel right away,” he adds.

Germany’s leading engine manufacturer sees three possible uses for hydrogen: Converted to sustainable aviation fuels (SAFs), hydrogen could be dropped into existing aircraft and engines right away. “Direct combustion of liquid hydrogen in gas turbines is possible in technical terms, too,” says Dr Stefan Weber, Senior Vice President Engineering and Technology at MTU in Munich, highlighting the second possible use. That would require some adjustments in the engine, especially the combustion chamber, which Weber thinks could be done in just a few years. By contrast, much larger challenges await for infrastructure and aircraft manufacturers, since they will have to find ways to provide and transport the liquid hydrogen and then carry it along inside appropriate tanks inside the aircraft.

Emissions free?  lol

Yep, it's an emissions shell game, moving the emissions from the tailpipe to the hydrogen refinery and power plants providing power to the refinery.

Some technologies, IMO, are not very compatible with a battlefield environment. Lithium batteries don't like violent shocks, and I suspect that hydrogen fuel tanks wouldn't either.

If, as anti-Covid-vaxxers claim, https://www.poynter.org/fact-checking/2021/robert-f-kennedy-jr-said-the-covid-19-vaccine-is-the-deadliest-vaccine-ever-made-thats-not-true/ , https://gospelnewsnetwork.org/2021/11/23/covid-shots-are-the-deadliest-vaccines-in-medical-history/ , The Vaccine is deadly, where in the US have Pfizer and Moderna hidden the millions of bodies of those who died of "vaccine injury"? Is reality a Big Pharma Shill?

Millions now living should have died. Anti-Covid-Vaxxer ghouls hardest hit.

.  .  .  I suspect that hydrogen fuel tanks wouldn't either.

This brings up another problem.  Hydrogen can't be stored long term.  Due to it's small molecular size, it will leak through the walls of any container at a rate of around 1.5% per day.  If you put 10 gallons of gasoline in your car's gas tank and then don't drive it, there will still be 10 gal in that tank 15 days later.  But with hydrogen, that 10 gal would have dwindled down to 8 gal, with the other 2 gal escaping into your garage.  Think of what 2 gal of vaporized gasoline could do to a house.

Well the obvious solution is get rid of garages for cars... All that wasted structural space isn't planet friendly anyway...

We are regressing with our "new" mandated technology...
