by Jacob Holley  (Grand Forks Herald) D3MAX creates cellulosic ethanol using “bolt-on” technology – more or less meaning it is a one-size-fits-most process which, according to the company, can be implemented at approximately 190 corn dry mill ethanol plants in the United States.

…

The aviation industry could be headed for an increase in ethanol aviation fuel production as part of President Biden’s Sept. 9 announcement that his administration is partnering with the airline industry to reach the goal of replacing all jet fuel with sustainable alternatives by 2050, with the hopes of producing three billion gallons of sustainable fuel by 2030 as part of what is being called the ‘Sustainable Aviation Fuels (SAF) Grand Challenge.’ Aviation currently makes up as much as 4% of the total greenhouse gas emissions by the United States — the most of any means of transportation.

…

Sustainable aviation fuel can be made from plants, waste and other organic materials, which in turn reduces the industry’s carbon footprint. D3MAX helps make ethanol from corn stover by converting corn fiber and residual starch left in distillers grains to cellulosic ethanol.

However, the advantage D3MAX and other companies championing corn stover-based ethanol have over soybean oil and vegetable oil is simple — there’s more corn stover. READ MORE

AdvanceBio selected for SAF pilot project development and design (Ethanol Producer Magazine)

Excerpt from Ethanol Producer Magazine: The project, called SAFFiRE (Sustainable Aviation Fuel from Renewable Ethanol), will demonstrate reliable, low-greenhouse gas (GHG) production of SAF from corn stover in a fully integrated, 10 metric ton per day pilot-scale facility. The novel process utilizes NREL’s low-temperature deacetylation and mechanical refining (DMR) pretreatment, enzymatic hydrolysis using Novozymes commercial hydrolytic enzymes, C5/C6 sugar fermentation to an intermediate ethanol product using commercial yeast from Lallemand and LanzaJet’s alcohol-to-jet (ATJ) process to convert the ethanol to SAF. In addition to the low cost, high titer, highly fermentable sugars produced in this reliable low-cost pretreatment, the valuable, non-condensed lignin produced will be recovered, dried and pelletized for sale as fuel pellets or sold directly for upgrading, all contributing to the lifecycle analysis (LCA).

“We identified a new process pathway that permits attainment of a negative GHG emission target. This approach is so transformative that our LCA concepts will be adopted by many entering the field from now on,” said Mike Himmel, NREL Senior Fellow.
