Sustainable Combustion Systems and Their Impact

As the world enters the third decade of the 21st century a shift in global energy demand and use is anticipated. The transportation industry is one of the largest energy users with major environmental consequences. Additionally with the most ambitious electric vehicle predictions the bulk of cars sold in 2040 will still have internal combustion engines. As a result we must continue to explore all options for reducing IC engine emissions as well as pathways to reduce potential vehicle CO2 emissions. Hydrogen on the other hand which can be used in both internal combustion engines and fuel cells is seen as one of the futures most important energy vectors. In terms of production storage and application this technology still faces several challenges. This Special Issue features original research papers as well as important review articles on current issues relating to laboratory research and in-vehicle test results on different renewable combustion strategies that seek to reduce environmental impact.
