new Honda Hydrogen Fuel Cell cars..water vapor is one of the biggest greenhouse gasses?
Question by superchic180: new Honda Hydrogen Fuel Cell cars..water vapor is one of the biggest greenhouse gasses?
These cars claim to emit no greenhouse gasses, however water vapor is one of the biggest, albiet natural, greenhouse gasses that we have. I suppose a ‘natural’ greenhouse gas is better than CO2, among others, however is it going to really contribute to lowering GHG emissions and global temperatures over the years?

the honda fuel cell uses natural gas, so it also emits CO2. To get the H2 it needs, Honda installs a natural gas reformer that takes in water, natural gas and emits CO2 and H2. So what have you gained with the H2 fuel cell? Why not just put natural gas into a regular car that cost 0,000 less?

Water vapor is a feedback, not a forcing. This means while it can amplify global warming, it cannot cause global warming.
The amount of water vapor in the atmosphere depends on the temperature of the atmosphere. As long as nothing else is causing the planet’s temperature to change, you can emit as much water vapor as you want and it will just fall back to the earth as precipitation. If something is causing the planet to warm (like CO2 accumulating in the atmosphere), then the amount of water vapor in the atmosphere can increase and cause the planet to warm further. For further details, see Myth #9 at the link below.

However, since 96% of our hydrogen currently comes from fossil fuels, fuel cell cars do still contribute to CO2 emissions and thus global warming.

You are close. But the hydrogen stripped of methane gives more energy as electricity than it would if used directly as methane in an internal combustion engine.
The carbon is sacrificed to get the energy to split it from the hydrogen, by emitting CO2. We get less CO2 this way than we would by burning the methane in internal combustion engine.
So we reduce GHG emissions, including water vapor, because we reduce water vapor emissions as a result of improved energy efficiency.
But water vapor, while an important GHG is non-persistent in the atmosphere. It precipitates. We only increase water vapor by raising global temperatures. OK, there is a very slight very temporary effect when we release water vapor. But we get so much of our water vapor from the seas. the few tons we emit will be of no effect.

let me start off by saying Hydrogen is a great option for the concept of free energy. I built my first hydrogen cell about 5 years ago. Have converted over 50 vehicles in the last 10 years (gydrogen and EV) and now currently run 2 trucks (and another EV), my home hot water heater, home stove and home generator on hydrogen for free with caught rain water and the help of a $10 solar panel. I offer a step by step DIY guide to walk anyone interested threw the process. You can find it at www agua-luna com or you can email me.
There are basically 3 safe ways to make and use it… chemically, electrically and molecularly, the first 2 being easier so I’ll only discuss them here. The fallowing steps were taking directly out of a DIY guide I offer to those who would like to run their vehicles or home on hydrogen safely. The entire guide is available at www agua-luna com
On demand h2 generators are a bit different from the Hollywood versions like seen Chain Reaction with Keanu Reeves, that tend to explode violently every time a film is being made. However when used in an on-demand system there is no storage of hydrogen and oxygen in its gas form, only liquid (water) and is only transformed into gas “on-demand” in small cylinder size amounts. It’s actually safer then gasoline as it doesn’t evaporate, creating explosive fumes in the tank like gas. the following were actually taken out of my $5 guide available at www agua-luna com
Chemically
1. You’ll need a 6inch x 1ft schedule 40 pvc pipe. With pvc cement glue a cap on the bottom and use a screw on cap for the top. Drill a small hole (1/4inch or so) in the side close to the top, screwing in a small copper shut off valve. Place a few feet of stranded (food grade is good) flex hose to the valve and into the air intake of your engine (carburetor or fuel injections).
2. Now crunch up a couple aluminum cans (beer cans, soda cans etc) and drop them into the pvc pipe, along with a couple cups of lye (Red Devil drain opener has lye in it, some Clorox and Drano’s do to).
3. Then simply add water, screw on the top and wait a few minutes.
What happens in simplicity is that aluminum and lye don’t really get along so they battle, and as always the innocent civilians (water H2O) that the most casualties, by giving up its hydrogen and oxygen. This then builds up in the void of the pipe and is ready to be vented into your engine, by opening the valve. You may need to start your engine on gas then switch it off after the hydrogen starts burning.
Electrical is a bit easier then Chemically.
1. Simply take a small solar panel 1.5 amps is what I use ($9 at harborfreight.com), connect the 2 wires from the panel +- to 2 conductors (carbon cores of batteries work well, just be careful removing it from the jacket), but any conductive material will work ie. Copper, aluminum, steel, etc.
2. Drop the wires into a water tank (I use 55gal drums), make sure they don’t touch each other.
3. Drill a small hole (1/4inch or so) in the side close to the top, screwing in a small copper shut off valve. Place a few feet of stranded (food grade is good) flex hose to the valve and into the air intake of your engine (carburetor or fuel injections).
4. Then simply add water, screw on the top cap and wait.
After a few hours tiny bubbles will form and rise off one conductor (that’s hydrogen) and even smaller bubbles that just looks like foam will rise off the other (oxygen). I don’t remember which likes the positive and which likes the neg hydrogen or the oxygen.
The third method is more complicated and is what I use for my vehicles. It’s just a modified Joe’s Cell, there’s a step by step DIY guide available to walk you threw the process here www agua-luna com
It also covers the other 2 methods described in more detail.

Hope this helped, feel free to contact me personally if you have any questions if you’d like assistance in making your first self sufficient steps, I’m willing to walk you step by step threw the process. I’ve written several how-to DIY guides available at www agua-luna com on the subject. I also offer online and on-site workshops, seminars and internships to help others help the environment.
