Will electrolysis of sea water help create more oxygen and by releasing this oxygen in the air, dilute CO2?

Question

Global warming is caused by excessive amounts of CO2 in the atmosphere. If we release oxygen in the atmosphere, will the oxygen dilute the CO2?

Could we then use the Hydrogen (by product) as an energy source to power the electrolysis.

I think I just found the solution to stop Global warming? What do you think?

Answer 1

It is not the percentage concentration of CO2 that counts. It is the total amount that counts. A fixed number of atoms of CO2 will always block the same amount of IR light, no matter how much or little oxygen is mixed in with it.

Answer 2

Hardly. In order to disassociate the ions in water molecules, one must run electricity through the water. How are you going to produce the electricity? By burning fossil fuels, which create CO2. Additionally, you need to get the O2 from its liquid state to is gaseous state, so that would require you to vaporize it, using more energy. While you may be releasing O2, you are creating CO2 to do it, so you are not really solving the problem.

Answer 3

Using hydrogen to power the hydrogen production is like a perpetual motion machine.  It would not work because it is way less than 100% efficient.  

Hydrogen *can* be produced as a free by-product of nuclear power.  

The CO2 is very dilute now.  The energy would be better spent capturing and sequestering the effluent from coal power plants.

Answer 4

i think that is extremal difficult to do this. fist of all it is too expensive to do it anyone or any country. secondly it is a cycle you will use energy to make O ans that will Java as ares ult to prod use CO2.
