Failure to Launch: Why Advanced Biorefineries Are So Slow to Ramp Up Production

A common refrain is that advanced biofuels are just a few years away from commercialization—a claim that has been made for much longer than just the past few years. The U.S. EPA’s Renewable Fuel...Despite claims that advanced biofuels are just a few years away from commercialization, existing projects struggle to reach their nominal capacity.

Kinks in the pipeline: A survey of downstream alternative jet fuels challenges

We often hear about how biofuels and other alternative fuels will be needed to decarbonize the aviation sector in the long-run. How easy or difficult will this be to achieve? There are already some...Although touted by some as necessary to decarbonize the aviation sector, logistics are still an issue for alternative jet fuels.

Is the Renewable Fuel Standard enough to spur progress in advanced biofuels? Probably not.

Production of cellulosic biofuel is expected to fall nearly 7 billion gallons short of meeting the statutory Renewable Fuel Standard (RFS) volume for this type of advanced biofuel in 2018, which has...Government grant and loan guarantees, not the Renewable Fuel Standard, have been essential in spurring progress in the cellulosic biofuel industry.
