Editorial: Experimental and modelling approaches for clean combustion technologies

Despite the rapid growth in alternative energy source utilization, combustion technologies will still play a major role in the years to come. Indeed, the energy mix of the next decades will see a coexistence of wind and solar sources and of combustion of e-fuels or synthetic fuels derived from renewable energies or produced from electricity excess, biofuels produced from non-edible biomass conversion (Dryer 2015; Elishav et al., 2020; Kohse-Höinghaus 2022), or unconventional sour fuels (Gupta et al., 2016). Combustion processes are almost ubiquitous in modern societies through power generation systems, transportation engines, and industrial and domestic heating applications. Nevertheless, combustion also represents the major source of atmospheric pollution, and thus new or improved low-emission/low-carbon technologies are continuously sought by scientists and ndustry players. To achieve this goal, considerable multidisciplinary experimental, theoretical, and modelling efforts are necessary to improve the understanding of the physics and chemistry of flame propagation, fuel gnition, and pollutant formation paving the way for carbon-neutral technologies and greenhouse gas and pollutant emission reduction. The aim of this research topic was to present new results, findings, and developments in various disciplines associated with combustion science and pollutant formation and destruction.
