  • Decarbonizing aviation through low-carbon fuels will be beyond difficult

    It's unlikely that the aviation industry can meet its steep carbon targets almost entirely through the use of low-carbon fuels.

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

    Despite claims that advanced biofuels are just a few years away from commercialization, existing projects struggle to reach their nominal capacity.

  • Short-term barriers to energy cropping

    An essential step to reliably scaling advanced biofuel across the transportation sector and beyond is ensuring the availability of feedstocks.
