ORNL and Caterpillar developed a dual-fuel combustion system that enables diesel marine engines to run primarily on methanol by using a small amount of diesel as a pilot fuel for ignition.
Researchers at ORNL developed a new method to detect underground tunnels by sending acoustic signals upward from below the ground rather than downward from the surface.
ORNL researcher Vivek Sujan was named Inventor of the Year for his contributions to advanced mobility and energy technologies. His work has helped improve vehicle efficiency, power systems and transportation innovation.
The 2026 Fuel Economy Guide from the U.S. Department of Energy and Environmental Protection Agency shows that fuel costs depend on more than a vehicle’s make and model, including driving habits and maintenance.
Researchers at the Department of Energy’s Oak Ridge National Laboratory are studying ammonia as a low-cost fuel for marine applications, building on work that began more than 50 years ago with a student-designed vehicle and a bold engineering question:
Researchers at ORNL will share their discoveries and innovations at DOE’s Advanced Research Projects Agency-Energy Energy Innovation Summit in San Diego, California.
