The main focus is on innovative combustion concepts for future fuels (hydrogen, ammonia, methanol and other e-fuels) and their impact on fuel consumption, emissions and noise, as well as on advanced simulation, digitization and measurement technologies. The symposium focuses also on the overall system as key aspect for achieving the stringent GHG targets. Along with climate-neutral power generation, greening of the maritime sector will be a core element of the large engines area. To this end, the 4th LEC Sustainable Shipping Technologies Forum (LSSTF), is integrated into the symposium program. Overall, a comprehensive 2-days program awaits you with around 300 pioneers and visionaries of the global ecosystem in the areas of mobility, transport and power generation.
