Ethanol and biodiesel were the first main beneficiaries. In recent years more novel fuel types like renewable diesel, renewable natural gas and sustainable aviation fuel have begun to become more mainstream. The most talked-about new transportation fuel, renewable electricity, has been unable to generate RINs—not because doing so is prohibited by the RFS, but because EPA has simply failed to act on applications by renewable electricity providers to generate RINs. EPA has both the authority and information necessary to act on this issue, but a legal challenge against the Agency is ripe and may be necessary to prompt quicker action and ahead of the slew of other agency priorities. Success in such a lawsuit would yield valuable benefits to those in the renewable electricity value chain.
