Scientists, investors and other visionaries have been working on one approach, direct air capture, for over two decades.
The technology is now being deployed to help form a vital new industry tasked with removing carbon dioxide from the atmosphere.
Scrubbing the Sky explores the journeys of key individuals who have persevered in the face of many obstacles to provide us with this potentially invaluable climate intervention option — and the intractable challenges that remain.
“Humanity can't afford to have increasing amounts of excess carbon floating around in the environment, so we have to get it back out.”
Direct air capture (DAC) is one option for removing carbon dioxide from the atmosphere. By moving air through filters or chemical solutions, carbon dioxide can be extracted from air and then stored underground or in products.
“DAC is primed for public and private investments that are orders of magnitude greater than what we see today. Not only is the current generation of DAC technologies ready for deployment at the million-ton scale around the world, but there is an emerging set of DAC solutions at the demonstration stage with breakthrough potential.”
SCRUBBING THE SKY is 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, McKendrick’s investigation traces more than 20 years of the technology’s development, from Biosphere 2; to multimillion 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.
Figuring prominently in this narrative is the genius of Klaus Lackner who, along with others, 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 a critical climate intervention option.
The book will be available in bookstores on March 7, 2023 (February 7, 2023 in Canada). Digital copies of the book will be available on February 7, 2023.
McKendrick's meticulous reporting captures the birthing pains of direct air capture technology—pulling carbon dioxide out of the air—which, as the climate crisis worsens, could ultimately become one of the world's most important industries.
McKendrick's carefully researched dive into the hidden science of direct air capture reads like a fast-paced adventure story—one with enormous implications for all of us.
In Scrubbing the Sky McKendrick tells a compelling story of the people and companies searching for the breakthrough that solves our biggest climate challenge. By connecting the dots from historical insights, McKendrick allows for failures and missteps, but leaves us with a sense of optimism that this seemingly impossible task may be within our reach.
Join Ed Whittingham as he takes listeners on an eight-part audio tour of the evolution of direct air capture’s use to scrub the sky of carbon dioxide.
With help from author Paul McKendrick, Ed explores the birth of this important new industry, drawing on interviews to tell the stories of the researchers, developers, CEOs, funders, and politicians behind it.
The Scrubbing the Sky podcast will launch in 2024, check back here for more details.
