Toyota hydrogen testing

Yup but honestly, price really isn't the concern here. It's independence. We all know that costs a buck o five.

Gas is almost $2.50 a gal here (Texas) right now and it's still worth it to be independent.

 

Wait no, that's just freedom. My bad.

 

It’s available in lots of denser areas of California since that is where the Mirai has been piloted. It has its issues regarding cost and infrastructure, but they’re still cool in my book:

 

This is exactly why the technology has been around for decades, but it is not at all practical...
Remember those Hydrogen BlimPs ???

 

Do I ever! Those things are hilarious!

 

Cool, but didn’t really answer my question. I understand that oxygenates are undesirable in gasoline, but wondered why they’re undesirable in Normal C4.

While this was informative, it only answered my question partially. Ethanol isn’t a worry in crude oil refining, that I’ve ever heard of. Just trying to understand other aspects of my refinery. I understand that C4 is a major blending component of gasoline. My question relates to a specific NC4 client, and why this would not be optimal.

EDIT: I may be splitting hairs, but just curious why someone would need NC4 with oxygenates below 2%.

 

Cut em down!!! Lol

 

might be asking questions with no answers. Not sure. My mind is always racing though

 

I don't know if this is accurate but I think of RBOB as regular gasoline that's going to get dosed with 10% ethanol to make what the public calls regular gas. Ethanol is 100 octane so RBOB actually leaves the refinery at about 85 octane because ethanol gets added at the terminal.

Back in the days before ethanol, the 87 octane stuff leaving the refinery was regular unleaded (RUL).

 

The goal would be to increase solar efficiency until we have almost “free”/unlimited day time energy and then use excess electricity to split water molecules via electrolysis to make Hydrogen for vehicles and night time/non-sunny day usage. I think this is more likely to happen (and better for the environment) than switching everyone to battery power (lithium mining is nasty stuff, and chemical cell batteries won’t get much better than they are now, we are hitting the ceiling on the physics already - electric vehicles will never be as convenient as gasoline but Hydrogen could be).

This is more of a 20-30 year plan. Solar efficiency definitely won’t be scaled to what we need for this to be viable within the next 10-15 years, but based on the materials chemists I’ve spoken with (I’m an process chemist myself) it’s definitely doable but will take time as the research into solar cell materials is still very much in its infancy.

 

That's relative tbh. For many, it's more convenient. Even factoring in road trips.

The biggest issue is access to charging and multi EV charging on site. Which there are solutions for. It will scale naturally over time. It won't happen over night at all but with enough time it's possible. Just look how much ev production and the charging network has grown in last 5-10 years.

 

LMFAO, catch 22

 

Lol yup. That's a bummer.

 

If you have actually dealt with hydrogen, you would know that it will never be as convenient as gasoline. It's not fun to try to contain. It leaks out of everything and needs some crazy tanks to hold it, especially in a car.

 

^this

 

If I remember correctly leno was an old kerosene powered steam car from the turn of the century. I hardly think that's a fair comparison. Lol

 

I have done extensive research on fuel cell cars, including actually building one. Everything I am saying is based on that research and stuff my good friend who designs the damn things has told me. Believe me the only reason companies are pushing hydrogen is because it's currently cheaper/easier to make than a full battery vehicle. I am open to hearing something to refute that claim, but I have yet to see anything other than sales evangelists trying to push their products with no actual backing to their claims.

As for seeing efficient hydrogen in 2 years... Well for the last 20 years we have been perpetually 5 years away... At this point I'm going with I will believe it when it actually exists.

 

TOYOTA has been wrestling with hydrogen in earthy vehicles for many years. The problem as far as I know is that while it can even power space ships, it takes more energy to produce than what you get back.
It also has less power per unit than gas, requiring more storage. It solves the air pollution out the tail pipe, but the earth pollution produced to make it, not so much.

IMHO TOYOTA is (was?) on the right and only viable track (for the moment) with the full hybrid solution.

But the politics and hatred towards fossil fuels might force them off the right track.

 

This... This is the only currently viable solution... When doen right It has the power and efficiency advantage of electric, and the range and ease of refueling from gas

 

All joking aside…. another science fact that is often ignored is that through photosynthesis trees consume C02 and emit O2.
