Camelina-based renewable diesel has lowest CI & generates highest credits
In one aspect, all biofuels are carbon-neutral: the CO2 from their combustion is offset by the CO2 the plants take in during growth. But all the steps in making the fuel--agriculture, transportation and production--use energy or chemicals that can create additional GHG emissions.
The true carbon-intensity (CI) of any fuel must be measured using a total life cycle assessment, which also takes into account the source of the feedstock and whether it displaces food crops or has other environmental impacts. The steps leading to the approval of a biofuel are called its "pathway."
Global Clean Energy Holdings' renewable diesel (RD) has the
only non-food pathway certified by the California Air Resources Board (CARB), which gives it a very low CI in comparison to other biofuels, including RD from other producers.
For comparison, renewable diesel from soy has a CI rating of around 50 grams of CO2 emissions per megajoule of energy (50 gCO2e/MJ). GCEH's renewable diesel production using camelina feedstock has a CI of only 7 gCO2e/MJ.
Sustainable fuels produced at GCEH's refinery will also include renewable butane, renewable naphtha and renewable propane, all of which will be used for transport.
Unlike other animal feed produced by food crops, camelina meal reduces the impact on food markets
High-protein, non-GMO, camelina-based livestock feed is a premium product, FDA-approved for use as feed for cattle, chicken and swine.
Its production uses less agricultural resources than corn, soy or canola, all of which are widely used as livestock feed.
