One of the ways for sequestration of CO2 from the atmosphere is, after somehow separating it from the air, to react it with H2 - to get CH4 that can be used as an energy source. The H2 is obtained mainly by water electrolysis, using for that -electricity.
OBTAINING THAT ELECTRICITY - creates, in principle - CO2 that goes to the atmosphere
So the true amount of CO2 sequestration has to take that CO2 creation into the calculation. (Usually, it is said that "green", not from a polluting source will be used, but, since in principle, green H2 could be used directly as an energy source - reducing the amount of energy from polluting sources - it is not really an answer)
So I will be very grateful if you can give that number - How many moles of CO2 are created in a "dirty" electrical plant Coal/gas/ hydrocarbons for producing the electricity amount needed to produce a mol of H2 - say by electrolysis
thanks all for the attention

That depends, how do generate the electricity needed for electrolysis? Coal, gas, PV, wind? Anf even if you use coal/gas the details could make a lot of difference
