Oxygen content in biomass is 41-50%, whereas it is only 0.05-1.5% in crude oil, said Joyce Yang from the DOE’s Energy Efficiency & Renewable Energy (EERE) office.
“But when you pursue hydrocarbon fuels, there’s almost no oxygen so the strategic consequence is [that] there is potentially a significant loss of yield, up to 50%,” Yang added.
As a result, hydrogen would needed to supplement the lack of oxygen content in the biomass product, she said.
“So that means a lot to us in terms of our coming strategy [to displace oil] and how we deal with this program and process to still make it economically viable without subsidies,” she said.
The World Congress on Industrial Biotechnology conference runs through 19 June.
