Four Danish researchers have been awarded the prestigious European Inventor Award for developing a method that can significantly help fight air pollution in cities.
Tue Johannessen, Ulrich Quaade, Claus Hviid Christensen and Jens Kehlet Nørskov won the prize in the ‘small and medium-sized enterprises’ category for manufacturing a technology that can remove up to 99 percent of mono-nitrogen oxide emissions from diesel engine exhausts.

The researchers found a way how to store ammonia, a compound of nitrogen and hydrogen, in solid form by binding it with metal salts.
Their solid-form ammonia product ‘AdAmmine’ has already attracted a lot of interest, and the team recently landed a contract to instal their exhaust scrubber system onto 300 buses in Copenhagen.
The European Inventor Award is annually granted by the European Patent Office (EPO) to outstanding scientists, researchers and engineers who have made an extraordinary contribution to social development, technological progress and economic growth.
