Amelse, Jeffrey; K. Behrens, Paul (2021): Sequestering Biomass for Natural, Efficient, and Low-Cost Direct Air Capture of Carbon Dioxide. In SSRN Journal.

"The only way to permanently remove CO2 already in the atmosphere is to break the Carbon Cycle by growing biomass from atmospheric CO2 and permanently sequestering that biomass carbon."

"While large-scale deployment of DAC discussions continues, a closer look to the capital and operational costs, different capture technologies, the choice of energy source, land and water requirements, and other environmental impacts of DAC are reviewed and examined. Cost per ton of CO₂ captured discussions of leading industrial DAC developers with their carbon capture technologies are presented, and their detailed cost comparisons are evaluated based on the choice of energy operation together with process energy requirements."
