Alternative Fuel Systems

Alternative fuels like compressed natural gas (CNG) and liquefied petroleum gas (LPG) are becoming more popular as they are producing lower vehicle exhaust emissions and have more environmentally friendly production processes. For these reasons, governments around the world are beginning to support alternative fuel development. As a result, zero emission fuel cell vehicles using hydrogen are now an industrial reality. With new fuels comes the need for new fuel containment technology. All of these fuels induce specific containment needs, especially in term of permeability and mechanical performance. As a major innovator within the fluid transfer industry and leader in providing sustainable material solutions, Arkema continues to develop new solutions in this market.
