I like your plan.
For the past 30 years or more these over-unity cons show up like clockwork, i.e Hydrolysis using some secret resonant frequency or similar.
What internet sez>>>
80%
ยท Very roughly, a new electrolysis plant today delivers energy efficiency of around 80%. That is, the energy value of the hydrogen produced is about 80% of the electricity used to split the water molecule. Steam reforming is around 65% efficient.
It’s an 8-track!
Rebooting the 70s, bruh!
Looks like a hydrogen 8-track tape cartridge.
That's true and it will always be more economical to use natural gas. But there will be more and more renewable power used electrolysis or other forms of energy storage. Renewables simply won't work without storage.
True, there will eventually be giant solar farms for that infrastructure. Chances are they will be solar hydrocarbon rather than solar hydrogen, easier to move and store. I think they will end up being built in the third world and look like crap, but they will work.
They could put their supply runs off until winter.
LP is highly flammable yet millions of homes have a tank sitting close to a house.
With LP being pushed into the house under pressure.
Exactly, but charging a battery is also a net energy loss. The question is whether this technology can be made “more efficient” (cheaper? more energy-dense?) than a battery.
I always believed that there would be an alternative medium to Lithium-6 and that the government would NEVER commercialize L6.
No NOx if you burn it in a fuel cell, only if you burn it in an ICE or similar.
And where does the Hydrogen come from?
Electrolysis...you need energy to do it.
Cracking natural gas...you need energy to do it.
Also since H2 molecules are so small, leaks are very common and hard to fix.
All the easy stuff has already been invented.
“What if we run out of hydrogen?”
Don’t mention this to Al Gore. We’ll have a brand new movement on our hands. They’ll be chaining themselves to the ocean. Hmmm.
8-track players make a comeback!
It is not the motor or the drive train of EVs that is the problem. Both of those are relatively simple and better than the IC. It is the energy source that is the barrier to true success.
IC in the conversion of fuel to power is between 17 and less than 25% efficient. More energy is required to produce, refine and transport petroleum fuel.
EVs are somewhere around 75% efficient. Steam plants to make the electricity from coal are about 40% efficient and power lines take another bite out of the primary fuel to deliver the electricity to where it is used.
Each time you convert fuel to energy or power you destroy some part of it as waste heat.
I have been wondering what the full-cycle efficiency of any fuel is from resource to tractive effort? I bet it would shock us how bad it is even for solar or wind. There is always transmission loss. Energy to make the stuff and the power lines and install them has to come from somewhere. On and on the expense of energy goes with lots of contributory waste elements through each process.
Batteries have been against the wall in progressing the necessary qualifications for success of EVs for quite some time now. What is available is heavy, requires unacceptable charge times, degrades with time, can be unreliable, is expensive, uses what appear to be finite resources, has limited storage capacity generally providing enough 300 mile range under ideal conditions to get to somewhere short of your destination. It is the Achilles heel of the idea. I doubt hydrogen is the key as the net energy production process for it is negative. Breaking the hydorgen-oxygen bond requires a lot of energy as any successful entry level thermochemistry student should know.
If it were not for the batteries EVs would probably be a good idea but the range limitations and charging duration are unacceptable to me for all but local travel within 100 miles. Driving your battery powered car out to a mainline express thoroughfare and latching onto an electrified rail might be one way to cope with the range problem of batteries and charge them while underway. It would be one heck of an electrified rail and the construction and management of such a system would be phenomenally difficult.
Precisely.
See my musing post below wondering what the full conversion efficiency is for various sources of tractive force.
I wish him well and fully support the market creating new sources of energy.
Yet I still don’t see how producing, processing, and storing hydrogen will ever produce more energy than it took to get it in a useable state.
I assume it is reacted already to keep it in a “solid state” and the laser releases the bonds.
