You may be familiar with direct air capture, or DAC, in which carbon dioxide is removed from the atmosphere in an effort to slow the effects of climate change. Now a scientist at Lawrence Berkeley National Laboratory has proposed a scheme for direct ocean capture. Removing CO2 from the oceans will enable them to continue to do their job of absorbing excess CO2 from the atmosphere.
The need for negative emissions technologies to address our climate crisis has become increasingly clear. At the rate that our planet is emitting carbon dioxide – adding about 50 gigatons every year – we will have to remove carbon dioxide at the gigaton scale by 2050 in order to achieve “net zero” emissions.
Scientists at Berkeley Lab are working on new approaches to achieve direct air capture of carbon dioxide. Andrew Haddad, a researcher in Berkeley Lab’s Energy Technologies Area with a Ph.D. in inorganic chemistry, talks about how a Nobel Prize-winning chemistry concept from more than a century ago inspired his idea for efficiently capturing CO2.

Increasingly, scientists are recognizing that negative emissions technologies (NETs) to remove and sequester carbon dioxide from the atmosphere will be an essential component in the strategy to mitigate climate change. Lawrence Berkeley National Laboratory (Berkeley Lab), a multidisciplinary Department of Energy research lab, is pursuing a portfolio of negative emissions technologies and related research.
Reaching zero net emissions of carbon dioxide from energy and industry by 2050 can be accomplished by rebuilding U.S. energy infrastructure to run primarily on renewable energy, at a net cost of about $1 per person per day, according to new research published by Lawrence Berkeley National Laboratory, the University of San Francisco (USF), and the consulting firm Evolved Energy Research.
