CCS has two existential threats. One is the successful development of energy storage for intermittent renewables (wind, solar, waves). There is a lot of talk of pumped storage and batteries, but the real winner for large-scale, night-week-month storage will be hydrogen created by water electrolysis and stored in underground salt caverns. But the other threat to CCS is higher prices for natural gas and coal, and their eventual supply insecurity. They are non-renewable! Global peak coal was probably last year. Yes, more tonnes of coal are being mined, but they are poorer and poorer quality, having less net energy or requiring more energy to remove sulfur, mercury, particles, etc. CCS has a time window of about 4 years to show technical success and commercial competitiveness, after that, renewables and quantum improved energy efficiency in all we do will be unbeatable. Stay tuned.
