Decreasing the NOx and particle pollution generated by transport over the last 20 years has primarily been achieved by fitting catalysts to petrol fuelled vehicles. Recent statistics shows a limited impact of this approach. We propose a new route using additives to liquid fuel decreasing the emission of combustion-related pollution. This new solution is compatible with the existing technologies ensuring synergy between complementary approaches. Our previous experience with additives to solid fuel has shown a strong impact for industrial sintering, yielding a reduction in NOx by factor of 3. The principle and efficiency of this process will be extended to other sectors, in particular to road and maritime transport.
