Mechanical engineer Jennifer Wade is leading two federally funded projects that are addressing the critical question of how to remove greenhouse gases from the atmosphere, thus slowing the devastating effects of global climate change. It’s part of a national effort called the Carbon Negative Earthshot: Being able to remove carbon at $100 a ton at a scale of a million tons per year. That’s a difficult task, Wade says, but it’s not an insurmountable one.
Physicists at Georgia Tech have proven — numerically and experimentally — that turbulence in fluid flows can be understood and quantified with the help of a small set of special solutions that can be precomputed for a particular geometry, once and for all.
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.
