Title: Sustainable fuel for the transportation sector

Abstract

A hybrid hydrogen-carbon (H{sub 2}CAR) process for the production of liquid hydrocarbon fuels is proposed wherein biomass is the carbon source and hydrogen is supplied from carbon-free energy. To implement this concept, a process has been designed to co-feed a biomass gasifier with H{sub 2} and CO{sub 2} recycled from the H{sub 2}-CO to liquid conversion reactor. Modeling of this biomass to liquids process has identified several major advantages of the H{sub 2}CAR process. The land area needed to grow the biomass is <40% of that needed by other routes that solely use biomass to support the entire transportation sector. Whereras the literature estimates known processes to be able to produce {approx}30% of the United States transportation fuel from the annual biomass of 1.366 billion tons, the H{sub 2}CAR process shows the potential to supply the entire United States transportation sector from that quantity of biomass. The synthesized liquid provides H{sub 2} storage in an open loop system. Reduction to practice of the H{sub 2}CAR route has the potential to provide the transportation sector for the foreseeable future, using the existing infrastructure. The rationale of using H{sub 2} in the H{sub 2}CAR process is explained by the significantly higher annualizedmore » average solar energy conversion efficiency for hydrogen generation versus that for biomass growth. For coal to liquids, the advantage of H{sub 2}CAR is that there is no additional CO{sub 2} release to the atmosphere due to the replacement of petroleum with coal, thus eliminating the need to sequester CO{sub 2}.« less
