As he returns from COP22 climate talks in Morocco, Minister Frydenberg is boasting other countries impressed by projects making progress with CCS, “one of the biggest in the world being Gorgon LNG”.  If you look, you find “it’s a whole 3.4 to 4 Million tonnes of CO₂ planned to be stored each year”. It’s compulsory to separate CO2   from methane, out of gas wells, to match fuel compliance standard, before it can be sold. CO2 concentration can be 15% or more, filtered out using membrane technology.  Unfortunately total annual emissions for Australia are now rising towards 600Million tonne/year. Most emissions are from combustion in power stations, vehicles etc, measured in ppm(parts per million), so carbon capture and then storage is not so easy and there’s no indication that Frydenberg has any intention of making CCS compulsory. How can this scale of problem be ignored by Australian government, not even pretending they need to mitigate against risk of collapse. They may not care about environment but do they really not care about the precious economy?
