New pressure method captures 99% of CO2 for just $26 per ton

"In each stage, more of the carbon dioxide bubbles out and can then be compressed for permanent storage in underground formations."

That sounds like a drawback to me.  Underground storage is likely to be expensive, and it may not be truly permanent, since CO₂ could potentially leak out.

I strongly believe it's a shame to waste carbon dioxide.  It's a valuable resource because it acts as plant food, boosts crop yields, and contributes to the greening of deserts.  It also warms the planet slightly.  Before that warming becomes a serious problem, we reportedly will likely run out of fossil fuels — in roughly 125 years.  Most fossil fuels may be depleted by around 2100, and we have only about 50 years of oil reserves left.
