The Bioenergy Technologies Office has awarded an additional $350,000 in funding to scientists at the National Renewable Energy Laboratory (NREL) to develop a pilot scale system for turning biomass into sustainable aviation fuel.
The NREL team has published new research about its fully integrated process to produce a fuel precursor, in this case, butyric acid, from lignocellulosic sugars, or sugars derived from dried plant material. Butyric acid is a promising precursor for diesel and jet fuel and is typically developed from a colorless, petroleum-derived gas called propylene. Through their research, the NREL scientists estimate that their biomass-derived butyric acid could result in a 50% reduction in greenhouse gas emissions compared to traditional biological production routes and can be sold at 55% of the current selling price of petroleum-derived butyric acid.
