The MYTP outlines the research plans for overcoming these barriers. “Barrier vs. cost curves” are
proving useful in describing the barriers and targets for each program area, and are derived from
the experimental and target cases.
Each area of the program is at a slightly different place in their development of these curves:
Biomass Supply: The feedstock interface analysis team is leading the effort to analyze
current and future supply-cost data for a variety of feedstocks.
Biomass Infrastructure: The feedstock interface analysis team has developed a first-cut
state of technology case for corn stover and wheat straw collection and from that supply
system barriers and targets.
Sugar Platform: The Biofuels program developed an experimental data case for ethanol
in FY00 and it has been updated regularly.
Thermochemical Platform: Experimental data cases will be developed for
thermochemical processes in FY04, which will enable a more robust quantification of the
barrier targets in the thermochemical platform.
Products: The current plan is to quantify the barriers and targets for technologies that
could enable the “Top Ten” study products, resulting in a single unit operation barrier vs.
cost curve rather than a whole process curve. These unit operation barriers can then be
integrated into a process curve. The “fermentation strains/catalysts” bar on Figure 6 is an
example.
