Power plants already have a more effective and much cheaper option than carbon capture: use a zero-carbon power source. Even nuclear is cheaper. Many countries have committed to zero-carbon electricity production by 2035, and all countries should.
OTOH, carbon capture is still in the technology demonstration phase, and there is no way that it can capture 100% of power plant emissions by 2035.
Carbon capture at source is still a good idea for industrial emitters that don't have good zero-carbon options. For example, cement production might be one of those.
