Caterpillar inks deal to research MeOH-fuelled marine engines

Under the terms of the CRADA, ORNL researchers will work with Caterpillar over the next few years to identify, develop and test hardware configurations and operating strategies required to maximise the use of methanol in engines retrofitted for methanol.

Research will be conducted on Caterpillar’s in-line 6-cylinder marine engine that has been modified for methanol use and installed at DOE’s National Transportation Research Center at ORNL.

New engine designs will also be considered, and several engine combustion strategies will be explored including dual-fuel, dimethyl ether reforming and spark-ignited prechambers. Caterpillar will support ORNL by providing additional materials and research expertise to enable engine performance, efficiency and durability while reducing GHG and other emissions.

The project supports DOE’s Vehicle Technologies Office’s focus on reducing GHG emissions from off-road vehicles including marine vessels. In addition to DOE’s Vehicle Technologies Office, the collaboration is funded by the U.S. Department of Transportation Maritime Administration.

“Caterpillar is proud to be working with ORNL as we develop the technology for a lower carbon future. Our marine customers across the U.S. have been clear that methanol will play a key role in their journey to net-zero emissions. The maritime industry has unique challenges that can’t necessarily be met by technologies being developed for other transportation sectors, so it is important to have this collaboration with ORNL to accelerate the technology and set the path for the future,” said Brad Johnson, vice president of Caterpillar Marine.
