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.
Physicists and soil scientists at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have teamed up to develop a new method for finding carbon stored in the soil by plants and microbes. This new method for measuring carbon pulled out of the air promises to be an important tool for fighting climate change and developing more ecologically friendly forms of agriculture.
