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.

Can alternative jet fuels crowd out demand from the road sector?

In the aviation industry’s vision of the future, neatly laid out by the International Civil Aviation Organization, airlines can meet all of their obligations under the Paris Agreement through simple...Proponents of alternative jet fuels often ignore the reality that many other sectors have laid claims to limited bio-resources as part of their own decarbonization strategies

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.

Bioenergy can solve some of our climate problems, but not all of them at once

Bioenergy has become a popular decarbonization strategy—so popular that policy makers and researchers in several sectors are claiming biofuels, bio-electricity, and bio-heat can deliver a large...Bioenergy has become a popular decarbonization strategy to reduce greenhouse gas (GHG) emissions. However, even if bioenergy production is maximized, competition across industry sectors is high.

The hardest part of cellulosic biofuels in India might be collecting the rice straw

India recently announced its National Policy on Biofuels, which includes ambitious targets for ethanol and biodiesel produced primarily from non-food and non-feed sources. The policy aspires to...A new policy in India aims promote cellulosic biofuel production from sustainable feedstocks, something no other country has managed to do. Can the country succeed?
