The following table lists commonly used diesel fuels and blends for data center generators.

Fuel/Blend Description GWP Value Energy content
Diesel Fuel Grade #2 (DF2) The standard choice for most data center diesel generators, offering high energy density, wide availability, and consistent performance. 1430 10.7 kWh/L
Diesel Fuel Grade #1 (DF1) A lighter, more refined diesel fuel made from kerosene, providing superior cold-weather performance compared to DF2. 1430 9.9kWh/L
Winterized Diesel A blend of DF1 and DF2 with special additives for cold weather operation. Prevents fuel gelling and maintains liquid state in extreme cold conditions. ~1430 ~10.7 kWh/L
Biodiesel (B100) B2 to B20 Biodiesel is a renewable fuel produced through a process called transesterification, which converts organic materials like animal fats, vegetable oils, and recycled grease into long-chain fatty acid esters. It's commonly blended with conventional petroleum diesel in ratios ranging from 2% to 20% biodiesel (designated as B2 to B20 blends). ~25-50 ~9.8kWh/L
