Currently, a startup business based in Knoxville named Holocene has been granted a license to further develop this technology, specifically a sustainable chemical intended for absorbing carbon from the air.According to Dr. Susan Hubbard, deputy for science and technology at ORNL, “ORNL is combating climate change by developing numerous technologies that reduce or eliminate emissions.” “But with billions of tons of carbon dioxide already in the air.
