Clean Fuels Alliance America applauded the approval of the latest revision to ASTM D396, the standard specification for fuel oils. It now includes new grades for biodiesel blends containing 21 percent to 50 percent biodiesel by volume. The updated heating oil specification marks a major milestone for the clean fuels industry and supports the expanded use of higher biodiesel blends in heating applications. The revision provides users and consumers of Bioheat fuel with clear guidance on fuel properties and procedures needed to deliver the same or improved performance as fuels currently in use. “In the Northeast and Mid-Atlantic states where Bioheat fuel adoption continues to grow, the updated standards provide greater confidence in the performance, reliability, and emissions benefits of blends up to B50,” said Scott Fenwick, the technical director at Clean Fuels. The National Oilheat Research Alliance called this another step forward in providing consumers with a high-quality renewable energy source.
