Reply to comment by broyoyoyoyo in Toyota to Convert Older Cars to Eco-Friendly Models to Curb Emissions by renome

The correct ICE fuel would be biofuels... With genetically engineered plants increase yield. We already have plants designed that would roughly replace 25% of existing US fuel consumption and make ICE engine emissions almost entirely a moot point. I get my 25% number from working back from the 50million acres currently used for corn and soy that are grown strickefly for biofuel (both are terribly inefficient compared to the possibilities)

See lipidcane and lipidshorgum. Which currently yield about 10x the oil of soy and double the ethanol per acres relative to corn from one crop.

Pretty much all gasoline vehicles can be converted to ethanol...and biodiesel is in many ways superior to petroleum diesel.

Hydrogen is one of the worst ICE fuels in everything except emissions.

Also opposed piston diesels can do 50% better than next generation ultra stringent emissions standards...so again why no traction on real solutions?

Ethanol and biodiesel do not solve the global warming problem. They were never a solution, only a temporary relief measure.

That's a bald faced lie. Also people produce emissions... If you hardline everything to that point...

Emissions on modern gas and diesel engines are ultra low except for CO2..... And this can be completely recovered via carbon cycle so long term will nullify thier carbon footprint (within a growing season, 1 years worth of automotive CO2 is insignificant as a load to the ecosystem.... constantly adding more is not).

They produce emissions and there's no way for them to ever not produce emissions. I've worked in the car business, your bullshit isn't working on me.

Hydrogen is absolutely incredible for efficiency, reliability, emissions...it's great at nearly everything except energy density, which it's absolutely God awful at. Unfortunately energy density is by far the most important aspect of a practical vehicle, because nobody wants to drive around in a tanker full of literal rocket fuel just to have a range beyond a hundred miles. There's a reason the space industry has all but abandoned LH2. I can see it being an incredible alternative to battery storage at a utility scale, but not at a vehicle scale.

Though you are correct in the energy density being bad, it's also horribly inefficient to MAKE it. The work and power requirements outweighs the benefit is a other draw back

Hydrogen makes steel brittle...can permeate it directly, and has incredibly bad energy density...
