Technologies are being developed to enable a feed of biomass to be gasified, producing a fuel that has a high CO and H2 content; which may then be used in stationary gas engines to supply energy in the form of electricity and heat. This creates an opportunity to develop more effective, economic solutions for the clean-up of emissions from such engines, in line with the European Waste Incineration Directive (WID).

Ammonia selective catalytic reduction (NH3-SCR) is the current industrial practice for NOx control from stationary sources. NOx Storage and Reduction (NSR) processes, where NOx species are ‘trapped’ before they are subsequently reduced through alternate lean and rich-burn cycles, also use ammonia as the reductant of choice.

Hydrogen may also be used as a reductant in these processes, and as it is already be present in the system it negates the need for additional chemicals and their associated costs. The development of a catalyst material which can facilitate the reduction of NOx using hydrogen is the primary aim of this research. It may also be possible to combine SCR and NSR, using hydrogen as the reductant, to create a hybrid design, further improving the efficiency of the NOx treatment process.

Recent work has focused on commission of the experimental set-up, catalyst preparation and calibration of analysis equipment.
