CO2 capture will unfortunately never be practical. Assuming we can get the cost down to $100/ton (which is very optimistic!), the cost of capturing all CO2 emitted by fossil fuels per year would roughly equal 20% of the total US GDP. Limiting emissions will always be orders of magnitudes more efficient.
