Yes, Hydrogen (H2) is great.

 

It cost five times more per kilometer than a battery electric car.
 

You take your electricity and instead of putting it straight in your battery car, you electrolyze water to make hydrogen and oxygen, you then use electricity to compress that so you can put it into tankers. Then you drive the tankers to your local fuel station using hydrogen in the process. Then you use more electricity to transfer into the fuel station tanks. Then you use more electricity to pump it into your car. then your car probably uses a fuel cell which is about 50% efficient as it wastes a lot in heat reducing the whole thing to 20% of the efficiency of having a battery electric car in the first place.

 

So consumers will love the hydrogen car because it cost five times more to run.

 

Where do I order one?

OTOH owners will not be faced with either having to spend half the price of the EV to replace the battery or having to scrap a perfectly good vehicle because they cannot afford to buy a new battery.

 

When you talk about putting electricity straight into your EV battery you carefully omitted to mention how much electricity is used to actually build the battery in the first place, nor how much electricity will be used to scrap and salvage the battery at the end of its working life.

I don't think Toyota shareholders will care 2 hoots if you disagree with Akio Toyoda's statements

The main difference I see is you want to force a product on people regardless if it meets their requirements or not where Toyota have a range of products and leaves the final choice to their customers

At the moment people prefer  hybrid over EV

However, that doesn't mean Toyota is abandoning EV investment entirely. It unveiled two EVs concepts at the Japan Mobility Show this week, including a spiritual successor to the MR2, and it recently debuted concepts for an electric Land Cruiser and compact electric pickup. So Toyota is still very much invested in electric cars; it just also believes EVs are part of the answer for a carbon-neutral future. For now, the market appears to be bearing that out.

https://www.thedrive.com/news/akio-toyoda-says-slowing-ev-demand-proves-he-was-right-all-along

I expect EV sales to grow in Thailand this year but I don't think we will see total sales of 152,628 which would be a 100% increase of the 76,314 EV sold in 2023 as its a more cautious customer base that EV manufacturers have to sell to

According to this article BYD look like their 1st pickup will be a gas hybrid

As for the power option that BYD chooses to launch first in 2024, it will be a gasoline engine. It works with a plug-in hybrid electric motor (PHEV), while a pure electric version (BEV) will be ready for sale in 2025.

https://www.headlightmag.com/2024-01-10-spyshots-byd-truck/


And I don’t care two hoots if Toyota’s shareholders disagree with my opinions either. I stand by my analysis.

 

I don’t have a horse in this race and I’m not pushing my opinion on any consumers.  Toyota’s horse is having an increasing number of legs cut off it over the next 11 years and the replacement foal is not out of the womb yet.

 

I don’t think we will see 100% growth in EV’s this year either but I do think 50% is probable.

 

I read about BYD’s pickup too, it’s going to be very interesting to see what happens when BEV pickups are available.

When I said "some other HydroCarbon" I was referring to something other that what is used now, i.e. fossil fuel HydroCarbons, Ammonia is of course NH3 and contains no carbon.

 

 

 

 

.

 

Yes I agree pickup sales are huge here and we don't have a BEV pickup here yet, I think BYD are bringing one here at the end of the year.  I can't see any reason why they should be any less successful with pickups than with their cars.

When you say " some other hydrocarbon" it's a bit like a report that a body was discovered in the forest by a tramp in a state of advanced decomposition. One has to feel sorry for the tramp. A syntax error.

 

You are probably correct about pickups, although Tesla's Cybertruck is a dismal failure.

Tesla’s Cybertruck can’t be anything other than a failure.

 

They can’t be sold in the EU or UK because they don’t meet type approval because the steel is too thick and rigid.  Equally, they are too difficult to make and Tesla can’t ramp up production.

 

The other issue is how do you repair them. Suppose you have a shunt and you have a dent, you’re screwed, or worse, the chassis is damaged.

 

I see them as rich men’s toys, they don’t even handle well on rough ground.

 

The Rivian on the other hand is a good product, but likely to be decimated by BYD.

I agree with you that a 50% growth on EV sales in Thailand is achievable on Pickups it will be interesting times if you divide pickup's into 2 categories 1) poser pickup and 2) workhorse pickups as they have different battery requirements with the workhorse pickups requiring a larger battery to cope with daily loads.

 

I have seen reports of batteries being unstable or unreliable once the battery drops below 20%

some EV owners reporting range drops from 12km to 0km in less than 30 seconds

The costs for electricity during manufacture is of course already priced in. And nobody is going to pay for scraping the battery, they will get money because they sell it. What you really want to look at is the emissions created over the lifetime of a EV compared to an ICE vehicle and here the EV wins hands down: https://www.epa.gov/greenvehicles/electric-vehicle-myths#Myth2

Those with disposable income are going to love high performance BEV pickups. Expect all kinds of tacky accessories, maybe flame decals and furry dice will return together with sunshade strips at the front saying "SOMCHAI" on the drivers side and a Velcro’d area for his wife, gig, meeanoi or whoever else is in it that day.

 

I think we can subdivide the workhorse pickups into two sub-categories, those that are used around town and don’t cover more than 2-300km per day and those working the fields or doing large mileages. The former are likely to go BEV because they are so much cheaper than the ICE equivalent per km.  The latter maybe not so much, time will tell.

 

Then we have the really poor pickup drivers whose trucks are already over 25 years.  They won’t be going BEV anytime soon, unless they win the lottery.

 

There are a few BEV’s where the last 20% of the battery can be reported less than accurately.  I think it’s a mixture of poor software and BMS not functioning correctly, often caused by users not following the manufacturer’s instructions on charging. BYD ask you to discharge below 10% once every 6 months, and fully charged once a week.  It’s mostly for the BMS to be kept accurate (I think).

Nuclear. Almost all Gen IV reactors and especially SMR's have have provisioning for hydrogen generators to be attached, as well as desalination units.

 

The hydrogen problem is more about safe storage and distribution. And yes, I will agree that hydrogen technology is still lagging behind other energy and propulsion tech, but I think that once the distribution on a larger scale can be implemented, it will be solved. All it needs is a $$ injection and some research tech. C'mon Nissan, Toyota and Mitsu.... you can do it

After all, what can be better when you're burning fuel with only water vapor as a byproduct.

 

McKinsey & Co. see Hydrogen being involved in transport for long haul operations accelerating in 2040, in their recent Hydrogen Outlook report they talk about how it will be produced.  Pink Hydrogen (Nuclear) doesn't figure in their forecasts at all, it is almost exclusively expected to be green hydrogen produced through electrolysis of water.

 

You begin with electricity and after 80% losses it's turning the motor in your car, lots of investment will never bring this below 50% losses and it is for that reason that BEV's will be the premium product, they will cost between 20%-50% per mile to fuel.

 

Pink Hydrogen is prohibitively expensive.

Electrolysis is a very inefficient way to produce hydrogen. Nuclear hydrogen generators use thermochemical technologies, which only requires heat, or hybrid technologies such as the high temperature steam electrolysis (HTSE) and hybrid thermochemical cycles, which require both heat and electricity.. And the nuclear reactors, especially Gen IV, generate that in abundance.

And yet Pink Hydrogen is not in the analysts forecasts.

 

I agree with you though.

Not in the McKinsey report you're linking. But many other sources talk of using nuclear exclusively in the future hydrogen production. 

 

In fact, the stigma of using nuclear power is slowly fading and we see more acceptance for nuclear from the general public.

The biggest obstacle to a larger deployment of nuclear is, IMO, current legislation, which centers on dinosaur size NPPs with capacities of several TWe, building cycles of 20-30 years, billions of $ in cost, and high maintenance in it's relatively short lifespan. Not to mention costs associated with waste storage.

The Hydrogen Highway  -  a road to nowhere 

 

Keep seeing comments in discussions about EVs like this:  “of course the future is Hydrogen” but never anything to back it up.

 

About the only place in the world that still has Hydrogen cars is California or more accurately just the Bay Area and Los Angeles. So what is like owning a H2 car in California?

 

This video was published 12 hours ago and shows the current situation.

Where do I order one?

Hydrogen can be produced from different sources in different ways to use as a fuel. The two most common methods currently are steam- methane and, as you say,  electrolysis. However, researchers are working on developing other, alternative methods. It remains to be seen how this work progresses, but reports indicate significant progress. It is quite possible that  hydrogen as a commercially practical fuel will be widely available within the next 5-10 years.

"... a commercially practical fuel will be widely available within the next 5-10 years."

 

this was already said about 20 years ago ... :cheesy: :cheesy:

 

 

copy from www: Hydrogen has the potential to play a significant role in the future of transportation,

especially for heavy-duty vehicles (like trucks and buses) and in regions with strong government support.

However, its widespread adoption for passenger cars will likely depend on advancements in technology,

infrastructure development, and how it competes with battery electric vehicles ...

I agree. All I would add is that it would be unwise to entirely exclude hydrogen at this point.

Well you want to see some facts about H2 fuel cell technology? 

https://en.wikipedia.org/wiki/Fuel_cell

It shows how long it is there, starting from 1838 !

Interesting to see, at least I thought, Didnt even knew it is that old !

Hydrogen will get overhand in time. There are many processes which need heat and H2 is doing fine and produces only H2O, water.

There are "some" windmills here and sometimes see them standing idle,

Amazing , waste of wind energy, as his brother besides him runs, not creating H2. Grid issues.

Too much power on the grid !

I see we have  a working H2 plant on 132000 solar panels ! OK that amazes me again, no windmills.

250 kg/day, transported in  500 kg containers a 300 bar. It is an experiment plant. 

 

But ok now they are "working " on real H2 plants and fast I just red. They need too, as in climate agreement.

Of course money will flow in they, expect. Maybe also as increasing H2 cell fuel cars.

But first for chemical processes, like making steel. 7 H2 projects subsidized !

And if you see it is in many ways used, it is only really a matter of time, it replaces BEV's.

It is a race, as they are also developing batteries. Sodium would be the next one?

We have a lot of sodium.

Your BEV has a guaranty about 8 years, so after that ?

Red someone had to replace batteries of his Tesla, costing a whopping 16000 $.

It was due to leakage water into battery compartment. that would be production fault.

BUT however 16000 $ ! Would you buy a second hand electric car close to 8 years?

SO the cars are throw away items after about 8 years?! And the price new, jeepers.

 

Another thing is making fuel again from CO2, yes with green H2, they can do and then we have recycle system. DOnt know if they do already, but red about subsiding some major oil companies to capture CO2 of proces and pump it in underground empty gas wells. Major investment 5 billion euro's.

Of course creating fuel from CO2, cost some energy and lots of H2.

Also they have project about CO2 . from air, capture devices to install in whole country, all because of climate and agreements to reduce. 

 

The main issue is... money, all other things are secondary, even climate.

The climate is dictating, we should do otherwise, but it has to bring in money.

Global economy is based on more and more, a Ponzi scheme and it could as any other fail at one time.

I still think there are too many people and growing on this planet.

The cost and inconvenience of Hydrogen means it will never replace BEV's.

 

People keep saying the cost will drop and processes will improve, however even with perfect efficiencies in each process, it will still be 3 to 4 times more expensive per kilometer.

 

If governments started subsidising Hydrogen, that would make a difference, but no government can afford that.

 

The McKinsey report on Hydrogen says it will be used in trucks and PSV's, not cars, and for the reasons I've outlined.

 

We've tried Hydrogen cars, the experiment in every country it's been tried ended in failure.

Hydrogen is definitely the fuel of the future, like fusion energy, but common usage is probably 25 - 50 years off.

 

In an ideal world, clean hydrogen could be produced from electolysis of water using electricity from nuclear power plants, The same plants, if strategically located, can  produce fresh water from desalination of salt water, as well as steam and heat for industry.

 

Science fiction tells us of unlimited hydrogen being scooped from the sun and gas giants if space industries ever become profitable.
