Carbon sucker

Here is some additional info:

While this technology could play a part in the fight to reduce climate change,   its exorbitant costs pose a serious challenge. According to a 2011 paper, the cost of removing one single ton of atmospheric CO2 is anywhere from $600-$1,000.

Experts estimated that total CO2 emissions in 2017 were around 37 billion tons, which means the world would need about 370,000 of Carbon Engineering’s plants to absorb all emissions.

The discrepancy between cost and effectiveness is tempering scientists’ enthusiasm for DAC as a long-term solution to human carbon-emissions. However, Carbon Engineering has developed a potential solution to this problem by creating a highly-valuable byproduct from their carbon removal process: clean fuel.

Carbon Engineering predicts that fully-operational commercial plants would be able to remove carbon from the atmosphere at a cost of only $100-$150 per ton.

And even Bill Gates is investing in this.

Good that they have Gates on board, because to bring the technology to that cost effective level they're going to need some serious venture capital, or government subsidies; probably both.
