Hydrogen energy for internal combustion engine, Issues and perspectives

Abstract

Current internal combustion engines operate mainly on hydrocarbon-based fuel in the automotive transportation field. Their CO₂ emissions are inevitable because they are a combustion product and greenhouse gases responsible for global warming and climate disturbance. Hydrogen seems to be an alternative solution because its combustion does not generate greenhouse gases and it will help a longer preservation of conventional fuel reserves. This paper discusses the integration of hydrogen as alternative fuel in automotive transportation field. Issues and perspectives are considered.
