Iceland opens world’s first negative emissions’ power plant

It is expected remove an estimated 50 metric tons of CO2 from the air each year where it will be turned into limestone and stored in the ground.

The project is still in the pilot phase, but researchers believe negative emissions plants could be set up around the world. One major obstacle in place is the price. Climeworks estimates it runs around $600 to extract one ton of carbon dioxide from the air. However if economies of scale can be utilized and more plants open up, that price would drop significantly.
