Highly efficient and stable Ru-free catalyst for hydrogen generation from ammonia

Green Car Congress

Although the thermocatalytic ammonia decomposition reaction (ADR) is an effective way to obtain clean hydrogen, it relies on the use of expensive and rare ruthenium (Ru)-based catalysts, making it not sustainable or economically feasible. A complete ammonia conversion to hydrogen was achieved at an economically feasible 450 ?C

Load-control strategies for ammonia-hydrogen dual-fuel engine for hybrid power systems

Green Car Congress

A team at Beijing University of Technology has evaluated four load control strategies—throttle, ammonia-hydrogen ratio, air–fuel ratio, and variable valve timing—for an ammonia-hydrogen dual fuel Miller cycle spark ignition engine in a hybrid system. A paper on their work appears in the journal Fuel. 2023.128396

Researchers use chemical looping process to produce hydrogen from hydrogen sulfide gas

Green Car Congress

Researchers at The Ohio State University have used a chemical looping process to produce hydrogen from hydrogen sulfide gas—commonly called “sewer gas”. Hydrogen sulfide is emitted from manure piles and sewer pipes and is a key byproduct of industrial activities including refining oil and gas, producing paper and mining.
