CCS is certainly attractive, but I didn’t include it due to the primitive nature of the technology. However, there are now some examples of successful CCS schemes; one power plant in my region has recently become (or is at least claiming to be) carbon negative as a result of carbon capture. I am relatively certain this will be the way forward in the future, and it will come soon too — perhaps we will see widespread implementation within 5 or 10 years.
The reason why I can make that prediction is because, as you say, it isn’t detrimental to fossil fuel companies, but rather beneficial. However, there is a potential roadblock. If fossil fuel companies feel that allowing any environmentalist advancement will lead to their demise, they may well turn away from CCS and other technologies out of fear.
