NORA has initiated a large-scale field study to test 100% renewable liquid heating fuels in over 130 homes across Massachusetts, Pennsylvania, and New Hampshire.
As a valued member of Eurofuel, NORA's leadership and findings are strategically important for all stakeholders within the industry.
The study assesses two fuel blends: RD80/BD20, which consists of 80% renewable diesel and 20% biodiesel, and RD50/BD50, a 50/50 mixture. These fuels are employed in existing heating systems without requiring any modifications. The performance and impact on equipment are monitored throughout the entire heating season and into the off-season. This practical approach aims to demonstrate the viability of renewable fuels without the need for expensive infrastructure changes.
Chevron provides renewable fuels, partnering with Broco Energy in Massachusetts and Rhoads Energy in Pennsylvania for distribution and blending. NORA has classified the test homes into two levels: Level One sites undergo regular combustion analysis and inspections, while Level Two homes are assessed based on service records and user feedback. Early results are promising, with no significant fuel-related service issues reported, which reinforces confidence in the reliability of these blends.
This initiative leverages the extensive laboratory experience of NORA's Research Director, Dr. Tom Butcher, who emphasises the strong performance of renewable fuels in laboratory settings. As Michael Devine, NORA President, notes: ‘the liquid heating industry now has an option to provide not only traditional heating oil, but also a domestically produced renewable energy.’
This study is highly relevant for Eurofuel and its members, as it shows how renewable liquid fuels can be quickly integrated into existing heating systems, a crucial step for many European countries focused on decarbonisation.
Europe can learn from the U.S. model, which includes fuel blending at the terminal level, distribution via existing channels, and engaging customers through trust and environmental awareness. The use of ASTM-conforming blends like RD80/BD20 could guide potential EU standardization, facilitating policy harmonisation and cross-border implementation.
The study aims to deliver tangible results by spring 2026, serving as an important advocacy tool for clean heat standards and carbon reduction policies in both the United States and Europe.
