Direct air capture (DAC) technologies extract CO2 directly from the atmosphere at any location, unlike carbon capture which is generally carried out at the point of emissions, such as a steel plant. The CO2 can be permanently stored in deep geological formations or used for a …

May 11, 2023 · Carbon dioxide removal (CDR) includes technology-based solutions such as direct air capture with storage (DACS) and bioenergy with carbon capture and storage (BECCS); nature-based options such as afforestation and reforestation; and speeding up naturally occurring processes, such as enhanced weathering.

In the IEA Net Zero Emissions by 2050 Scenario, DAC technologies capture more than 85 Mt of CO 2 in 2030 and around 980 MtCO 2 in 2050, requiring a large and accelerated scale-up from almost 0.01 MtCO 2 today. DAC is a key part of the carbon removal portfolio.

When it begins operations in 2024, DAC 1 is set to become the world’s largest direct air capture (DAC) facility. This landmark project is an important development that can help demonstrate the valuable and unique role of DAC for meeting net zero goals.

Direct air capture plays an important and growing role in net zero pathways. Capturing CO 2 directly from the air and permanently storing it removes the CO 2 from the atmosphere, providing a way to balance emissions that are difficult to avoid, including from long-distance transport and heavy industry, as well as offering a solution for legacy emissions.

Specific energy consumption for CO2 capture using current DAC technologies - Chart and data by the International Energy Agency.

DAC. DAC technologies extract CO 2 directly from the atmosphere for permanent storage (carbon removal), or for use, for example, in food processing or to produce synthetic hydrocarbon fuels (where the CO 2 is ultimately re-released).

S-DAC = solid direct air capture. Related charts Role of low-emissions fuels in global gaseous final energy consumption in the Net Zero Scenario, 2015-2030

Apr 25, 2024 · Includes large-scale projects with a capture capacity of more than 100 000 t per year (or 1 000 t per year for DAC). Capture projects for CO2 use are included as long as CO2 is used in fuels, chemicals, polymers, building materials, or for yield boosting.

DAC CO2 capture costs range from USD 135/tCO2 to USD 345USD/tCO2, while biogenic CO2 feedstock costs range from USD 15/tCO2 to USD 30/tCO2. Biofuels covers hydrotreated vegetable oils (HVO) and biomass-to-liquids (BTL) fuels reflecting biomass feedstock costs from USD 5/GJ to USD 15/GJ.
