Decarbonized Combustion: Research Needs for Zero Pollution

Climate change is the biggest challenge that our society faces. In order to deliver the required reduction of carbon emission s, a smooth transition is needed from the existing infrastructure to a new approach that is yet to be agreed at an international level. As a consequence, combustion technologies are expected to remain important during the development of new infrastructure over the n ext 30 years. However, combustion technologies must be in a position to deliver zero pollution, which include carbon, NOx and particulates and other substances, specific to different industrial processes. The talk will identify and review different combustion tech nologies that can deliver net zero carbon emissions and overall zero pollution within short and medium timescales , which include: 1. Hydrogen and its vectors (e.g. Ammonia) 2. Supercritical CO2 3. Solar or e-fuels 4. Metal nanoparticle fuel The relevance of these approaches to aviation, land and marine transport and power generation will be considered. The scientific challenges that future research must address in order to deliver these combustion technologies will be presented.
