Biodiesel Demonstration:Theodore Roosevelt National Historic Site Biodiesel Demonstration(ST7949-1)

Brookhaven National Lab


New York State is a major user of fuel oil for heating. Nearly three million households (about forty percent of the population) and numerous businesses in New York State use almost 2 billion gallons of fuel oil per year for heating. New York State fuel oil customers also represent 25% of the oil heat market in the United States. Improved oil-fired technologies and cleaner fuels offer the potential for significant energy, environmental and economic savings.

Project Description

Field testing will be performed of B20 and B100 biodiesel fuels to identify and work with fuel oil dealers, service technicians, and equipment manufacturers to resolve equipment and cold weather problems such as difficult ignition, gasket and seal deterioration, and cold weather clouding and waxing. The testing will also seek to evaluate the expected benefits of biodiesel, including reductions in nozzle varnishing, heat exchanger fouling, and pollutant emissions. Technical assistance will be provided by Brookhaven National Laboratory to on-site staff at the Theodore Roosevelt National Historic Site in regard to fuel delivery and storage, equipment operation, and service and maintenance procedures.


(1)Reduced price vulnerability from consumption of imported crude oil and refined products (2)Reduced pollutant emissions into the environment (3)Reduced equipment cleaning and maintenance costs for oil heat customers. (4)Increased economic competition with the natural gas industry due to enhanced stature of fuel oil in the market place (5)Potential economic development benefits in New York State related to production and distribution of biodiesel fuels and feedstock.

Project Results

B20 and B100 biodiesel blends were demonstrated. An emissions evaluation was conducted and compared to that of standard heating oil, with which the B20 and B100 blends resulted in lowered emissions. Blending the biodiesel with low sulfur heating oil further reduced the SOx emissions. Seal issues were investigated, and all nitrile seals were replaced due to their incompatibility with biodiesel. Standard flame sensors have issues sensing biodiesel flames as biodiesel burns cleaner. A pamphlet has been developed outlining the use of biodiesel at Sagamore Hill.
