Heirloom Carbon raises $150M to remove CO2 from the air using rocks
The startup is betting that by building bigger and capturing more carbon, it can bring down the cost to remove each metric ton of CO2.
Further warming increases the risk of catastrophic consequences, including more frequent extreme droughts, floods, and fires; stronger hurricanes; faster-spreading infectious diseases; and declining wildlife and fish populations. That’s still far more than the $100 per metric ton that experts say is the sweet spot to make carbon capture a viable industry, although Corielle added that the company is “on a trajectory” to hit that price over the long term. Japan Airlines’ participation in the round is notable for the fact that some experts argue it will be easier and cheaper to continue flying using fossil-based jet fuel and remove the resulting carbon pollution through direct air capture.
