OK, I'm all for cleaning up our fuels before we use them, but I think this is kind of a "blind them with fact"s deal.... Natural gas does have a few contaminants in it such as CO2 and sulfer compounds that need to be removed. But focusing on this as some sort of breakthrough is misleading. Natural Gas is mostly methane, CH4. That is one carbon molecule and 4 hydrogen molecules. Here comes the chemistry part, when this is burned, that is combined with oxygen. The carbon gets cozy with an oxygen, O2 and produces a CO2 and the 4 hydrogens make 2 H2O's and a bunch of heat is produced. The heat is used to do the work of heating your home, cooking your food, or distilling crude oil to make gasoline. So you see there is truly no way to get the CO2 out of the natural gas. It is a combustion product. The amount of CO2 that is scrubbed from the raw gas is a small fraction, compared to the amount of CO2 that is produced by it's use. To truly scrub the CO2 from the methane would require removing the carbon altogether, but wait, that leaves you just hydrogen. Oh right, that again.  I won't go into all the hydrogen drawbacks on this rant. But let's just assume you could get the carbon out, without using any energy, just using magic. This is only for the sake of argument. since we know there is no such thing right?

We magically remove the carbon for the CO2. Also known as carbon black a valuable commodity, and we are left with.... 2 H2's. As we know from what we have been told, Hydrogen is a clean fuel, with only water vapor as the exhaust. Who wouldn't want that. Except for one thing. Without the carbon molecule we have lost 64 percent of the energy, almost two thirds! That means we will need at least 3 times more natural gas to do the same work.  plus whatever energy we need to remove the carbon. Since magic only works in front of an audience or on you tube...
