Hydrogen Fueling Infrastructure Development
The availability of stations providing reasonably priced hydrogen in places where vehicles will be deployed remains a key challenge to the adoption of this technology. To address the challenges, the U.S. Department of Energy (DOE) launched H2USA—a public-private partnership with fuel cell electric vehicle (FCEV) original equipment manufacturers. H2USA is focused on advancing hydrogen infrastructure to support more transportation energy options for U.S. consumers.
There will be more than 50 retail stations online by 2019. These are replacing the early hydrogen fueling stations built to support demonstration projects that helped address transition barriers, as well as provide valuable data as the FCEVs began to penetrate the market. As the market expands, fueling infrastructure and vehicle rollout will need to grow together. Most of the retail hydrogen facilities being built are in the form of an added hydrogen dispenser at an existing gasoline station.
Safety, Codes, and Standards
Many of the hydrogen safety, codes, and standards today are based on practices from the chemical and aerospace industries. DOE is coordinating the efforts of codes and standards organizations to develop more robust codes and standards that ensure the safe use of hydrogen for transportation and stationary applications. One of the outputs of this effort is NFPA 2, a harmonized national standard for hydrogen vehicle infrastructure.

Construction and Setbacks
Among many considerations for code officials, the layout of a hydrogen fueling station must meet specific requirements for construction setbacks. This figure provides an example of a hydrogen fueling station layout, along with some of the required codes and standards.

In addition to the technical challenges being addressed through research and development, there are obstacles to successful implementation of hydrogen fueling infrastructure that can be addressed only by integrating the components into complete systems. DOE is developing and testing complete system solutions that validate integrated hydrogen and fuel cell technologies for transportation, infrastructure, and electric generation in a systems context under real-world operating conditions.
