The article puts it up as a question about whether this practice is worthwhile since the only logical solution to climate change is to de-carbonize. Personally I think that question isn't very nuanced, certainly de-carbonizing 100'a of tons from the atmosphere from just this one plant is a small net positive. Can't let it be an excuse to keep rolling coal in your F750'a but I'm still in favor of sucking as much carbon out of the air as we can.
Carbon capture has had trillions and decades and still can't reach reasonable efficiency rates. Certainly real world performance is nowhere near what it would need to be to make a contribution to the environment.
The companies investing in CCS are the companies mining fossil fuels and natural gas. They are using CCS to divert funding away from renewables and to greenwash their current mining operations. In most cases the material captured is used in further mining operations. Like a 2xdmg to the environment bonus.
