Presently, there are no guidelines to assist commercial vehicle fleets considering hydrogen as an alternative fuel. Thus, this project will provide general guidelines on the proper operation, maintenance, and inspection of hydrogen fuel systems in commercial vehicles. It will also evaluate the impact that hydrogen fuel systems may have on Federal Motor Carrier Safety Regulations (FMCSRs) and recommend any changes needed in commercial inspection/enforcement procedures.

The guidelines are intended to assist fleet managers who supervise commercial drivers on the road, as well as operations and maintenance personnel. The guidelines are not intended as in-depth specifications for use by Original Equipment Manufacturers (OEM). Responsibility for safety design standards, including those of alternative fuel systems for commercial vehicles, belongs to the NHTSA.

An additional project deliverable is a model template system safety plan for commercial vehicle fleets using hydrogen as an alternative fuel.
