Natural gas and biomethane for use in transport and biomethane for injection in the natural gas network - Part 2: Automotive fuels specification

This standard establishes comprehensive technical specifications for natural gas and biomethane intended for use as fuel in road vehicles, as well as criteria for the injection of biomethane into the natural gas grid. It serves as a critical reference for ensuring the quality, safety, and compatibility of gaseous fuels within the transportation sector across relevant jurisdictions. The document details the physical and chemical properties required for the fuel, covering parameters such as calorific value, composition limits, and purity thresholds necessary for efficient engine performance and emission control. It aligns with broader regional regulations governing the energy market and the transition towards sustainable transport fuels. By defining clear benchmarks, this specification facilitates the integration of alternative gaseous fuels into existing infrastructure while maintaining operational reliability for automotive applications. The guidelines address the specific requirements for vehicles powered by compressed natural gas or compressed biomethane, ensuring consistency in fuel delivery and consumption. Adherence to these provisions supports regulatory compliance and promotes the widespread adoption of cleaner energy solutions in the mobility industry without compromising vehicle safety or performance standards.
