Invention: Ammonia storage to reduce NOx

A team of Danish researchers developed a method for storing ammonia in solid form by binding it with a compacted metallic salt. Their innovation opens up possibilities for the energy-rich chemical to be used as a safe hydrogen source for fuel cells and hydrogen-powered cars. More importantly, it can be employed as part of systems that remove as much as 99% of the mono-nitrogen oxides from diesel engine exhaust.
