Direct Air Capture (DAC)
Direct Air Capture (DAC)
The process of removing carbon dioxide from the atmosphere and storing it elsewhere.
How Mammoth DAC plant works
How Mammoth DAC plant works
A technology that uses fans to pull air through specialized filters, trapping carbon molecules. These molecules are then mixed with water and pumped deep underground, where they react with volcanic rocks and eventually turn into stone.
Carbon Capture and Storage (CCS)
Carbon Capture and Storage (CCS)
The process of removing carbon dioxide from the atmosphere and storing it elsewhere, with the goal of reducing the concentration of this greenhouse gas.

Study Notes
Direct Air Capture (DAC) Technology
- Fossil fuel combustion releases CO2, contributing to global warming.
- Renewable energy sources (solar, wind) can reduce emissions but transitioning away from fossil fuels takes time.
- Climeworks is developing DAC technology to remove atmospheric CO2.
Mammoth DAC Plant
- Mammoth, the world's largest DAC plant, opened in Iceland on May 8, 2024.
- Emulates an in-home air purifier, using fans to capture carbon molecules.
- Carbon molecules are then mixed with water and pumped underground.
- Volcanic rocks react with the captured carbon, converting it into stone.
- Powered by geothermal energy, resulting in zero carbon emissions.
- Mammoth has a capacity to absorb 39,000 tons of CO2 annually (equivalent to removing over 7,000 cars from the road).
- Nine times larger than Climeworks' Orca plant (2021).
Criticisms and Perspectives on DAC
- Critics argue that DAC plants are expensive and divert resources from reducing fossil fuel use.
- Environmentalists, however, view DAC as a necessary complement to fossil fuel reduction.
- Klaus Lackner highlights DAC's substantial contribution to addressing climate change, emphasizing its potential to make a significant difference.
Future of DAC Technology
- Climeworks plans an even larger DAC plant in Louisiana (expected to capture 1 million tons of CO2 annually by 2030).
- Other companies like Occidental are also developing commercial-scale DAC plants (e.g., one in Texas expected to remove 500,000 tons annually by 2025).
- DAC technology is growing rapidly, potentially becoming more widespread and critical in the future, comparable to the evolution of a ubiquitous technology like smartphones.
- Advocates propose complementary actions like increased tree and plant planting for further carbon reduction.
