Richard Lydon of Clear Edge Filtration Group presented the case for using a ceramic media with an embedded catalyst. The result is high dust removal and high NO_x reduction. DSI ahead of the filter allows acid gas removal as well. There are many thousands of these filter elements already in operation on various industrial operations. Recent installations in the U.S. show high efficiencies.

Could this be the technology which allows small power plants to remain in operation?

It is actually possible to inject sorbents ahead of the catalytic filter. The new highly-reactive hydrated lime from Lhoist (HCl capture shown below) or the sorbent recovery technology from Neuman (NeuStream process shown below) could be coupled with the catalytic filter to provide cost-effective high-efficiency capture of all the major pollutants.
