The Carbon Capture Con
Quote
Carbon-capture-and-underground-storage “(CCUS)” tops the list of silly schemes “to reduce man-made global warming.” The idea is to capture exhaust gases from power stations or cement plants, separate the CO2 from the other gases, compress it, pump it to the chosen burial site and force it underground into permeable rock formations. Then hope it never escapes.
Lopulta näin:
Quote
Increased CO2 in the atmosphere encourages all plants to grow better and use more CO2. Unfortunately natural processes are continually sequestering huge tonnages of CO2 into extensive deposits of shale, coal, limestone, dolomite and magnesite – this process has driven atmospheric CO2 to dangerously low concentrations. Burning hydrocarbons and making cement returns a tiny bit of this plant food from the lithosphere to the biosphere.
Regulating atmospheric carbon dioxide is best left to the oceans and plants – they have been doing it successfully for millennia.
The only certain outcome from CCUS is more expensive electricity and a waste of energy resources to do all the separation, compressing and pumping. Unscrupulous coal industry leaders love the idea of selling more coal to produce the same amount of electricity, and electricity generators would welcome an increased demand for power. And green zealots in USA plan to force all coal and gas plants to bury all CO2 plant food that they generate. Consumers and taxpayers are the suckers.
Naturally the Greens love the idea of making coal and gas-fired electricity more expensive. They conveniently ignore the fact that CCUS is anti-life – it steals plant food from the biosphere.
Aina on kuitenkin se mahdollisuus, että noissakin pyrkimyksissä voi käydä näin. Eli onnistuminen, joka ei näy missään.
