Study Notes
- Carbon dioxide, released from burning fossil fuels, significantly contributes to global warming
- Renewable energy can help reduce emissions, but phasing out fossil fuels entirely will take time
- Climeworks is developing solutions to reduce atmospheric CO2 levels
Mammoth Plant
- Mammoth, the world's largest direct air capture (DAC) plant, was activated on May 8, 2024
- It is located in Iceland
- The plant uses fans to pull air through specialized filters, trapping carbon molecules
- The trapped molecules are mixed with water and pumped underground, where they react with volcanic rocks and turn into stone
- Mammoth is powered by geothermal energy and produces no carbon emissions
- Mammoth can absorb up to 39,000 tons of carbon annually, equivalent to removing over 7,000 cars from the road
- Mammoth is nine times bigger than Climeworks’ Orca plant, which opened in 2021
Criticism and Support
- Critics argue DAC plants are too expensive and distract from minimizing fossil fuel use
- Environmentalists believe that efforts beyond reducing reliance on fossil fuels are needed
- Klaus Lackner states that it is a bigger drop than any to date
Future Plants
- Climeworks is planning an even bigger DAC plant in Louisiana, USA, expected to capture a million tons of CO2 annually by 2030
- US-based Occidental is building a DAC plant in Texas, expected to remove 500,000 tons of carbon annually when ready in 2025
