Aviation could consume almost all available biofuel for decarbonization – maritime shipping needs to broaden its own strategy
A wholesale shift to low carbon intensity energy carriers poses huge quantitative and qualitative challenges for aviation and maritime.

Allow hydrogen storage to receive credits under 48E regardless of ultimate end use
The Issue Limiting 48E eligibility to hydrogen storage used for power applications is not required by the statute and is difficult to administer. Hydrogen storage should qualify for the section 48E investment tax credit (ITC) irrespective of the ultimate end use of the stored hydrogen. Treasury’s proposed guidance limits the…

Synthetic SAF can, and should, qualify for 45Z
Synthetic SAF will be an essential component of aviation decarbonization Synthetic sustainable aviation fuel (SAF) will be essential to decarbonizing aviation, especially as the sector’s demand for low-carbon energy carriers continues to grow. CATF analysis has shown that biofuel supply will not be able to keep pace with this demand…

Carbon intensity of vegetable-based oils must full account for cross-market substitution effects
Carbon intensity calculations for vegetable oil-based fuels must fully account for the effects of cross-market substitutions, in line with Congress’ restrictions on palm fatty acid distillates Diverting certain vegetable oils toward the energy sector can create supply gaps that may be filled by carbon intensive palm oil Congress sought to…
