2022 Teens Dream - Methane and Carbon emissions, from a danger to a benefit.

My dream/ idea is simply composed of steps, at first, we can get Carbon emissions from the atmosphere by Direct Air Capture DAC, or any other methods, then we can react it with hydrogen under some conditions, CO2+ 4H2 under about 3 mpa and 156 celecius and passes it on a catalyst such as nickel to produce methane and water, then we use methane in lots of ways by combustion, and this produce carbon dioxide and water, we collect water from the formation and combustion of methane to electrolyze it To have hydrogen and oxygen, and collect CO2 from the atmosphere and the methane combustion, to make another reaction and repeat the cycle.

This idea can be flexible and be applied in lots of forms, and has a great efficiency in producing energy with decreasing the amount of carbon dioxide out from methane usage, which increase the turnout on using methane, by this we can decrease the amount of CO2 and free methane and taking an action for our climate, and saving marine life, and we get a semi-clean energy source.
