D. Regulatory and Enforcement Mechanisms

1. Vehicles

a) Safety

i. FMVSS (light-duty vehicles)

ii. GTRs - Global Technical Regulations (light-duty vehicles)

iii. FRA (rail)

iv. FMCSA (heavy-duty vehicles)

v. FAA (aircraft)

b) Efficiency

i. NHTSA - Corporate Average Fuel Economy (CAFE) standards

ii. EPA - official fuel economy test procedures

iii. Develop hydrogen fuel consumption mass measurement procedures.

iv. Develop a means of accounting for, and correcting for, the effects of vehicle hybridization (i.e., energy storage) on fuel economy via high-speed current monitoring.

c) Emissions
Description: The EPA has regulatory authority over criteria pollutants (oxides of nitrogen, carbon monoxide, non- methane hydrocarbons, and particulate matter) and other toxic air emissions. This would apply to FCVs using on- board fuel reformation.

i. Develop measurement techniques.

ii. Develop official test procedures.

2. Hydrogen Transport

a) HAZMAT Regulations

b) Pipeline Regulations

c) Incident Investigation
Goal: Support rulemaking updates.

3. Weights and Measures
Goal: Assist the legal metrology community (primarily at the State level) to develop uniform device performance requirements, fair and equitable methods of measurement, and practical test procedures for commercial equipment metering of hydrogen at points of sale.
Description: Stakeholders include State Weights and Measures offices; industry manufacturers and trade associations (e.g., API, ASME, NCWM); device owners, users, and customers; and Federal (NIST) technical advisors.

a) Issues

i. Specifications, tolerences, and other technical requirements for H2 measuring systems

ii. Code development

iii. Method-of-sale requirements

iv. Inspection and test procedures, standards, and tolerences

a. Field inspections (State regulators)

b. Type evaluations (equipment)

v. Technical training

a. Training standards

b. Examinations and certifications

b) Contexts
Description: Each requires separate activity for gaseous and liquid (cryogenic) product form

i. Hydrogen producers

ii. Pipelines and transport

iii. Storage facilities

iv. Fueling stations
