KIOR is far more than a cellulosic ethanol company.
KIOR is one of a group of drop-in fuel companies that never had any intention of being a cellulose ethanol company. Some are still going full steam ahead with their development. Drop-in fuels are fuels that could replace petroleum fuels with, at most, minor modification to engines.
In the past, BFRE claimed it could make a minor modification to its factories to produce butanol rather than ethanol with all its problems. Butanol must have been overhyped as a fully adequate gasoline substitute with a slightly lower energy density since now one of the biggies is promoting a 50% blend with gasoline. BP was one of the most mentioned pushers of biobutanol.
IMHO the misfortunes of KIOR have nothing at all to do with those of BFRE.
