In this episode, we speak with Dr. Christoph Gebald, co-founder and co-CEO of Climeworks, one of the world’s leading direct air capture (DAC) companies. Gebald shares insights into Climeworks’ journey and vision for the future, and the crucial role of carbon removal in achieving sustainable aviation.

He discusses:

How their direct air capture technology (DAC) removes CO2 from the atmosphere and stores it permanently underground through mineralisation.
Climeworks has achieved a significant technological breakthrough with their Generation 3 technology, which doubles CO2 capture capacity per module while halving energy consumption, making it increasingly cost-competitive.
Climeworks’ notable partnerships with major airlines including SWISS, Lufthansa, and British Airways.
Climeworks’ second commercial direct air capture and storage plant Mammoth, which opened in 2024 in Iceland. The facility is designed to capture up to 36,000 tons of CO2 annually once fully operational and is the world’s largest DAC facility.
Climeworks Solutions, which offers a portfolio approach to carbon removal that combines their DAC with other methods like biochar and afforestation, meeting clients’ needs for diversified climate action strategies.

Throughout the conversation, Gebald emphasises the complementary nature of different climate solutions, the importance of both technological and natural approaches, and his optimism about consumer demand driving sustainable aviation.
