Like garbage before recycling, CO2 has been viewed as a waste. Now, it is a commodity too valuable to be thrown away and buried underground. And like recycling, the challenge is to match the CO2 from where it is created with where it can be used. Enhanced oil and gas recovery are two well-established commercial uses. Converting captured CO2 to construction materials like concrete is another.
This fascinating Wall Street Journal op-ed describes a fourth use that is currently available at small scale - combining captured CO2 with natural gas to make methanol - a transportation fuel that could replace gasoline.
There are seldom magic bullets in any area of life, and this one is no exception. Economics will rule. Still, could getting this newest CO2 recycling technology to scale - fed by cost-lowering CCS networks - be an opportunity to advance CCS, lower CO2 emissions from transport, take the fullest domestic advantage of huge supplies of shale gas, and achieve true energy independence?
