ICM Inc. has successfully completed two 1,000-hour performance runs of its patent-pending Generation 2.0 Co-Located Cellulose Ethanol process at the company’s pilot plant in St. Joseph, Missouri.
The runs were designed to prove performance of the co-located technology design for the conversion of cellulosic biomass feedstocks, including energy crops such as switchgrass and energy sorghum, agricultural crop residues, and forestry residues, to cellulosic ethanol and co-products.
The first performance run, which ran from March to late April, focused on switchgrass while the second run from early June to late July, focused on energy sorghum. Both runs were similar in nature, but with a few minor operational modifications included to allow for smoother operation between the two runs. The 1,000+ hours of continuous production in each run are a significant achievement, as it qualifies these data sets for federal loan guarantee programs.
“This achievement is important because it provides operational confidence at a commercially relevant scale. We used all commercial-type equipment for these performance runs that processed 10 dry tons of feedstock per day. At that scale, we were able to achieve continuous operations throughout both performance runs to generate key data required to move forward to commercialization as the market provides demand for Gen. 2.0 Cellulosic Ethanol and co-products.” said Dr. Doug Rivers, ICM’s Director of Research and Development.
ICM believes that the success with each of these three 1,000-hour runs comes from the dedicated individuals and extensive testing of various feedstocks at the pilot scale for next generation conversion technology to produce renewable fuels that meet low carbon fuel standards.
