Carbon removal methods.

Direct Air Capture uses large fan-like machines to pull CO₂ directly out of the atmosphere. Captured CO₂ can either be stored permanently in rock formations underneath the earth’s surface or reused for other materials.

Blue carbon is the carbon stored in coastal ecosystems, such as mangroves, seagrass meadows, tidal marshes, and shellfish reefs. Carbon is stored in plant biomass and the associated soils and sediments of these ecosystems.

Biomass sinking is a method that taps into the carbon sequestration potential of ocean biomass. CO₂ is permanently removed from the atmosphere by transporting seaweed to the middle of the ocean and sinking the carbon-rich biomass to its depths.

By heating up biomass to extremely high temperatures without oxygen, carbon is locked up in bio-oil. This carbon-rich material can then either be stored away permanently underground or be refined and used as a green energy source.

Trees are the earth’s natural carbon removal machines. Trees sequester CO₂ using photosynthesis and store it in every part of the tree. A single tree can capture up to a ton of CO₂ in its lifetime.

Soils are great at capturing carbon, but the overuse of soils over the past decades has reduced their ability to do so. Diverse techniques can optimize and help regain the carbon-capturing properties of soils.

Heating waste biomass to high temperatures without oxygen turns it into carbon-rich biochar. Applied to soils, biochar is great for storing carbon for a long time while simultaneously increasing agricultural productivity.

BECCS involves the combustion of biomass to create carbon-neutral bioenergy and the subsequent capture of the CO₂ produced. The CO₂ is then permanently stored in underground formations, resulting in a net carbon-negative impact.
