Scrubbing the Sky

Finalist for the Wilfrid Eggleston Award for Nonfiction Alberta Literary Awards An in-depth look at the people and the science behind our attempts to pull carbon dioxide out of the atmosphere with direct air capture. Drawing on interviews with stakeholders at the intersection of climate science, energy technology, and public policy, Paul McKendrick's investigation traces more than 20 years of technological development with direct air capture, from Biosphere 2; to multi-million dollar promises from Richard Branson, Bill Gates, and Elon Musk; to the opening of Orca, the world's largest commercial direct air capture facility, in Iceland in 2021. The question of what will be necessary for direct air capture to reach a meaningful scale, and how much it will cost, has fueled intense scientific and political debate, and spurred a value chain that spans finance, industry, technology, policy, and academia. McKendrick's clear and riveting prose presents the full story of this fascinating pursuit for the first time, inviting readers to learn more about this critical climate intervention option.
