Hot topics at Clean Sky’s Low NOx and Advanced Combustion Technologies Workshop: preparing the roadmap!

24 February 2020

While CO2 emissions and decarbonisation are receiving unprecedented levels of attention - and rightly so - considering the greenhouse gas issue, Nitrogen Oxides (NOx), Particulate Matters (PM), Carbon monoxide (CO), and unburnt hydrocarbons (UHC) remain a “burning” issue in terms of global warming. All of these pollutants are fundamentally linked to the combustion process and how to burn the fuel most efficiently.

More than 50 combustion experts from industry, academia, research centres came together at a workshop organised by Clean Sky on 19 February to discuss the State-of-the-Art and the way forward in low NOx and advanced combustion research.

The agenda of the day covered 14 presentations in 6 different sessions addressing burner concepts, experimental methods, particulate matters, additive manufacturing, hydrogen combustion and certification aspects. The majority of the contributions were from Clean Sky projects, among which 3 thematic projects launched 1 year ago (LEAFINNOX, CHAIRLIFT, and DENOX) on ultra-advanced NOx reduction technologies, as well as the recently-launched thematic project on PM modelling (RAPTOR).

The contribution from EASA in terms of outlook on future regulations, and all contributions from industry (Rolls Royce, Safran, Avio Aero, GE Aviation) and from academia and research centres, were outstanding and of excellent technical level. 

The objective of this meeting was also to discuss inputs for a strategic research and technology roadmap covering the mid-term (2035) and long-term (2050) horizons. Presentations of results from the former EU project FORUM-AE and input from the EVI-GTI Lab Gap Matrix complemented the numerous inputs received from the participants and were discussed during the concluding session of the workshop, with the aim to establish a strategic roadmap for non-CO2 emissions.
