CARB seeking public comment on RTE’s proposed CCS-related pathways

In California, the Air Resources Board together with the state’s Environmental Protection Agency have opened up a public comment period for Red Trail Energy’s application seeking approval for two designed-based starch ethanol pathways to take into account CO2 sequestration. The company already has two approved pathways for corn starch ethanol but if CO2 is sequestered into the Broom Creek Formation as proposed, the carbon intensity of its pathways would drop to 43gCO2e/MJ and 37gCO2e/MJ respectively.
