It is debatable that coal + CCS is more economical than CSP+storage, geothermal power, or several other renewable technologies. Let's keep CCS R&D going, and see what it really will cost before making any commitments on deployment. Claims by the coal industry of CCS are certainly not yet credible. It is certainly debatable whether CCS is environmentally safe. Sequestration sinks are unknown. It seems inconceivable that oceans are a good dumping ground, given acidification concerns. It seems inconceivable that deep ground injection will not lead to leaks back out in some hundreds of years time frame, making that approach deeply questionable. Indeed, continue the reserach, but CCS is FAR from obvious as an answer. A nice CCS propoganda piece.

Indeed, it is estimated that oil, coal and natural gas will provide 80% of the world’s power demand in 2030, with gas and coal providing 50% of this. So in 2049, magically, ten bazillion new turbines will appear to get the job done. Investment has to start now to transition in 2050. Dependence on fossil fuels will persist until 2050.
