Japan team reports pathway to green ammonia: photocatalytic conversion of nitrogen with water

Researchers in Japan report that a commercially available TiO2 with a large number of surface oxygen vacancies, when photo-irradiated by UV light in pure water with nitrogen—successfully produces ammonia (NH3). The solar-to-chemical energy conversion efficiency is 0.02%, which is the highest efficiency among the early reported photocatalytic systems. This is,... Read more →

CSIRO team working to commercialize membrane separating H2 from NH3; opening up an export market for Australia renewable H2

Researchers at Australia’s Commonwealth Scientific and Industrial Research Organisation (CSIRO) have years of experience researching the best ways to separate pure hydrogen from mixed gas streams. Now, the researchers have developed a thin metal membrane that can separate high-purity hydrogen from ammonia used as a hydrogen carrier. Ammonia (NH3) has... Read more →

Researchers at Oita University in Japan have developed an innovative process for the production of hydrogen from ammonia without the need for an external heat source to initiate or maintain the reaction. An open access paper on their work is published in the journal Science Advances. Liquid ammonia (NH3) has... Read more →

Study finds vehicles more important source of urban atmospheric ammonia than farms

Vehicle tailpipes are a more important source of ammonia’s contribution to urban air pollution than is agriculture, according to a study by researchers from the US and China. The paper is published in the ACS journal Environmental Science & Technology. Atmospheric ammonia (NH3) reacts with nitric and sulfuric acids to... Read more →

ARPA-E awards $35M to 16 REFUEL projects for energy-dense carbon-neutral liquid fuels; leveraging ammonia
