Innovating Low-Carbon Fuels
Hydrogen-based fuels have great promise, but considerable challenges related to related to, distribution, storage and utilization. Researchers at KAUST have developed technological solutions to use ammonia as a carrier for hydrogen. Our process combines the catalytic decomposition of ammonia and the separation of hydrogen with unprecedented energy efficiency and significant cost reduction. It also relies on existing infrastructure for ammonia transport, making it globally scalable. KAUST is also investigating blends of ammonia with other additives including hydrogen, methane, propene, dimethyl and diethyl ether, and dimethoxy methane. The resulting hybrid fuels can be used to power next-generation internal combustion engines.
KAUST’s chemical kinetic model of ammonia-DME fuel-blend combustion could help optimize fuel-engine interactions for high-efficiency internal combustion engines.
