La capture directe de l'air peut-elle vraiment éliminer le dioxyde de carbone ? | Anthony Taylor | TEDxKings College School

La capture directe de l'air est une technologie envisagée pour extraire le dioxyde de carbone de l'atmosphère après son rejet. L'intervention évalue son réalisme en examinant les coûts énergétiques imposés par la chimie du procédé, ainsi que la question de son financement à grande échelle. L'orateur, élève de sixième forme à King's College School à Wimbledon, adopte une conclusion mesurée, ni sceptique ni optimiste. La vidéo est issue de TEDx Talks.

• Extraction du CO2 de l'air après son rejet
• Coûts énergétiques de la chimie du procédé
• Qui paierait pour une mise en œuvre à grande échelle

Direct Air Capture proposes to remove carbon dioxide from the atmosphere after it has been released. Anthony assesses how realistic this is, working through the energy costs the chemistry imposes and the question of who would pay for the technology at scale. His conclusion is measured rather than either dismissive or optimistic. Anthony is a sixth form pupil at King's College School, Wimbledon. He is studying the International Baccalaureate, taking Mathematics, Physics, and Chemistry at higher level. He hopes to study Engineering at university and was recently awarded an Arkwright Engineering Scholarship, sponsored by the Royal Air Force. He is also a keen sportsman, with a passion for rugby and rock climbing, and enjoys volunteering with his local Scout group. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at https://www.ted.com/tedx
