The life of celebrated ORNL biologist Liane Russell was remarkable in many respects — from her childhood flight from Austria ahead of the Nazi invasion to her 60-year career as a trailblazing woman in the field of genetics to her decades of advocacy for environmental causes.

The combination of bioenergy with carbon capture and storage could cost-effectively sequester hundreds of millions of metric tons per year of carbon dioxide in the United States, making it a competitive solution for carbon management, according to a new analysis by ORNL scientists.

Prometheus Fuels has licensed an ethanol-to-jet-fuel conversion process developed by researchers at Oak Ridge National Laboratory. The ORNL technology will enable cost-competitive production of jet fuel and co-production of butadiene for use in renewable polymer synthesis.
