The California Air Resources Board held a public scoping workshop to discuss the hydrogen station verification process. Specifically, the workshop focused on the process needed to verify the fueling performance at hydrogen stations to help enable successful deployment of fuel cell electric vehicles, allowing the customer to experience safe, fast and complete fills at all stations. The discussion included the fueling protocol, back-to-back filling, station capacity and other station parameters. In addition, the workshop included a discussion about who will perform the testing, the qualifications for the testing agencies, testing device specifications, and under what circumstances the testing or degree of testing that should occur. This information was aimed at helping CARB determine whether to develop requirements through a regulation to verify station-fueling performance.
