WG2

Chemistry for control of by-products in Smart Energy Carrier conversion

Challenge: Pollutants monitoring and control

Objectives:

  • Compile inventories of pollutants emitted from the combustion of SECs in practical systems.
  • Increase understanding of the kinetics of combustion by-product for a sustainable use of SECs.
  • Assess control strategies for the mitigation of pollutant formation and emission.
  • Develop tools to detect and quantify chemical, physical and morphological properties of combustion-generated pollutants, particularly of particulate matter.
