The captured CO2 can then be stored underground or used to produce synthetic fuels or other products. DAC technology is still relatively expensive, but costs are decreasing as the technology matures. Companies like Climeworks are pioneering DAC technology.
• Afforestation and Reforestation: Planting trees and restoring forests can absorb significant amounts of CO2 from the atmosphere. Sustainable forestry practices are essential to ensure the long-term effectiveness of afforestation and reforestation efforts. Numerous global initiatives are focused on reforestation and afforestation, particularly in tropical regions.
• Bioenergy with Carbon Capture and Storage (BECCS): BECCS involves using biomass as a fuel source and capturing the CO2 emissions from the combustion process. The captured CO2 is then stored underground. BECCS has the potential to provide both energy and carbon removal, but it requires careful management to avoid negative impacts on land use and biodiversity.
• Ocean Fertilization: This involves adding nutrients, such as iron, to the ocean to stimulate phytoplankton growth. Phytoplankton absorb CO2 from the atmosphere through photosynthesis. However, ocean fertilization has potential ecological risks and its effectiveness as a CDR technique is still uncertain.
