Tar_alcaran, 2 months ago In reverse order: 1 - it needs to be tranported 2 - it needs to compressed and cooled, in order to transport it. You need to cool it down around 1700 degrees, because: 3 - methane pyrolysis is done at around 1500 degrees C, getting something that hot isn’t free. 4 - methane isn’t the only component in natural gas, so you need to seperate out all the impurities. 5 - methane is a very strong contributor to global warming, so any natural gas leak from the drill to the factory adds co2equivalent. 6 - you need to extract natural gas from the ground and transport it, which takes energy.
