Finally! Hydrogen Fuel Cell Vehicles

This is what I've been waiting for. A few years ago, at the Santa Monica Airport AltExpo, I was told that 2015 will be the year for Hydrogen Fuel Cell vehicles. If California can get an H2 station within striking distance of Thousand Oaks, I know what I'll be turning my Prius in for. This will make at least two auto manufacturers that will have FC based vehicles for the masses, Honda Clarity and Toyota's new vehicle. Now! For my home hydrogen generator...

This is really exciting news, but unfortunately it seems that those of us not in California will need to wait awhile beyond 2015 to see a fueling station emerge near us.

Fuel station is crucial to the adoption of different fuel technology to drive a vehicle. No doubt. When Tesla installed charging stations along HWY from Bay Area of LA and to NY, Tesla has got enough attention from the public. Stock priced soared. Given Tesla's success of demonstrations and stock price, I thought Honda would mimic the strategy to draw public attention to Clarity. Government supported to fuel cell technology given Honda Clarity a boost until the supported was pulled out. Honda was struggling to look for partners to continue fuel cell technology.


In 2014 CES, Toyota joins the fuel cell race. How is the Toyota's technology different from Honda's? Will Toyota's venture draw enough momentum to finally bring the public one more  alternative fuel vehicle? What will the future of Tesla be? Will EV co-exist with fuel cell vehicle? Among all, I do hope the fueling pump for Toyota fuel cell vehicle be the same as that for Honda Clarity.

Atmosphere of earth - O2 20.946%

If there are 10s of millions of FCV utilising Oxygen from atmosphere, will O2 % will reduce from 20.946% to much less value?

What will it generate - lot of water?

Internal combustion (gasoline) engines also utilize oxygen from the atmosphere.

The best way to produce hydrogen is solar-powered electrolysis of water.  In this case, you store the hydrogen and release the oxygen into the air.  When you recombine that hydrogen later in a fuel cell, you're taking the same amount of oxygen out of the air and the fuel cell gives you back the water.  So there's no net loss of oxygen.  The hydrogen is simply a great way to store solar energy.

If you produce hydrogen from fossil fuels, you do convert oxygen to CO2 at some point (bad) unless you're converting biowaste natural gas (good).

Home hydrogen generation is the obvious next step, but there are a couple of issues. Generating hydrogen is a trivial high-school science experiment, but pressurizing it is a little more complex. This is particularly true given the second issue, which is that it needs to be done safely. I would just as soon not read about any Hindenburg re-enactments...

Yes, finally indeed. Things are looking up for EVs, IMHO.

If I'm remembering this correctly, many years ago, perhaps it was 11 years ago, Toyota was experimenting not JUST on the fuel cell in the car, but also an on-board hydrogen reformer. As has been repeated on here several times, for the time being, on-board hydrogen reformer research has stalled? Well, I think it needs to un-stall, because without it, my bet is the FEV is going to be about as popular as the BEV.

That's not meant to be a compliment.

The O2 side intakes

Are we going to start seeing fancy new O2 intakes, on the sides of the hood, in all cars now? Sort of as a fashion statement?

Surely, internal combustion requires O2 intake too, no? Hint: what is the air cleaner for in cars?

LarryM99 - Ah! But, the compressing of the gas is no different than CNG tanks and the Home Setup for CNG. In addition, what is explosive energy in CNG as compared to CH2? We also need to remember that the Hindinberg did not explode, it burned.
