Renewable diesel, right, is made from fats and oils such as vegetable oil and used cooking oil and dyed red to distinguish it from other fuels. It’s processed to be chemically the same as petroleum diesel and meets the ASTM D975 specification for petroleum in the United States. Renewable diesel can be used as a replacement fuel or blended with any amount of petroleum diesel.
EPRI and the Tennessee Valley Authority (TVA) announced the successful demonstration of renewable diesel as a combustion turbine fuel for power generation. The demonstration was performed on a dual-fuel natural gas/diesel unit at TVA’s Johnsonville site in Tennessee that produced 76-megawatts, the full capacity given the day’s weather conditions.
The success of this test is expected to help open the door to greater adoption of a cleaner fuel that reduces overall carbon emissions by up to 75% compared to conventional petroleum-based diesel. Kevin Collins, TVA’s senior program manager for innovation and research, said the Johnsonville test set a record: With 76 megawatts of electrical output, it was the largest renewable diesel test anywhere in the world.
