Hydrogen cell cars ARE EV's, they just use a different battery tech. You can not charge them at home, so there's that, and they seem to be pretty far behind lithium-ion in so far as cost and efficiency.
As far as pure Hydrogen-powered cars, they will replace diesel for long Haul Transport and Heavy Machinery and will require a special fueling station, but the average Joe will not have access to this, and for good reason.
Siemens Energy, Duke Energy and Clemson University have teamed up to study the use of hydrogen for energy storage and as a low- or no-carbon fuel source to produce energy at Duke Energy’s combined heat and power plant located at Clemson University in South Carolina. The US Department of Energy...
Hydrogen as a fuel for automobiles is an environmental chimera (and not the female monster of Greek mythology ... this isn't a SCOTUS nominee thread).
H2 gas is made from methane (from natural gas). By-products of methane to hydrogen are hydrogen (duh, even I know that) and CO2.
Since there is an entire separate process (read: inefficient use of energy) to convert methane into H2 gas, and then the H2 is used in energy-inefficient car engines, I'm guessing (and admitting that I haven't attempted to do any research on the overall energy balance) that H2 fuel is no more effective environmentally than gasoline or diesel.
There are catalytic processes with methane that produce hydrogen and carbon, not carbon dioxide. Very high temperatures required, so thoughts are that fission heat will be required for scaled up production. I understand the holdup to be development of a cladding material that isn’t Chernobly graphite.
Thus why it takes very high temperatures and a catalyst. Plenty of papers on the subject. I haven’t worked in this area, but I heard “nuclear heat source if we can develop a high-T clad other than graphite” 15 or so years ago. Direct heating. People afraid of graphite after one accident.
I remember all the biching and moaning about that one. OMG, I can not believe the government is making me use a more efficient lightbulb that was not designed in 1880. This is obviously a power grab where GE will make more money than GE.
With the rate that the electric power industry is using natural gas (as a cleaner burning fuel than either coal or bunker oil), and with the USA's short-term political power play to export natural gas to the EU and other markets, the price for natural gas will rise gradually at first, and then at an accelerating rate, as the fracking-extracted gas gets depleted and supplies become harder to find.
With the rising price of natural gas (which will rise in price faster than oil &/or coal), the cost of hydrogen gas will also rise to unattractive levels.
H2 powered vehicles will be left holding the bag.
Let's see what Mr. A.Pounders has to say (and if he thinks keeping this thread alive is worth his time!)
Nothing you said is wrong, but you certainly overlap some short term issues with some long term issues.
Also keep in mind the price of hydrogen will continually come down over the next 10 years as the world generates hydrogen without using natural gas. If you’re wondering how that’s gonna happen ……. google is your friend.
