Abstract
The purpose of this paper is to give a strategic overview of the existing standards governing the construction and operation of hydrogen refueling stations. A succinct and comprehensive study of hydrogen refueling station standards globally, in Europe, and in Italy is conducted and discussed in light of the new European Hydrogen Strategy and Roadmap. Among the numerous topics examined, a particular emphasis is placed on the standards in force for on-site hydrogen production via water electrolysis, hydrogen storage, both liquid and gaseous, and refueling protocols for light-duty and heavy-duty vehicles, on an international level through the provision of ISO, IEC, and SAE standards; on a European level through the examination of the CEN/CENELEC database; and on an Italian national level through the analysis of the UNI database.
Highlights
Hydrogen as an energy carrier has tremendous potential to address a variety of important energy issues in a variety of industries [1]
Because transportation accounts for about one-third of worldwide carbon dioxide emissions, hydrogen adoption in the mobility sector, coupled with fuel cell technology, such as in Fuel Cell Electric Vehicles (FCEVs), is
This article presents an extended overview of Hydrogen refueling stations (HRSs) standards: - at an international level, by presenting ISO, International Electrotechnical Commission (IEC), and SAE standards; - at European level, by analyzing the CEN/CENELEC database; - and at Italian National Level
Summary
Hydrogen refueling stations (HRSs) must undoubtedly be implemented in this scenario They are at the core of the infrastructure that enables hydrogen-based green mobility, serving as the hub for the distribution required to support the delivery of hydrogen to FCEVs. the success of this novel technology is constrained by some impediments to future growth and development. The analysis was based on 2014 data, with documents gathered through a bibliographic review and information gathered via a questionnaire distributed to authorities and IA HySafe [5] members Another European Project, HyLaw [6], addressed a similar issue, extended to commercial adoption of hydrogen and fuel cell technologies by providing market developers with a comprehensive understanding of relevant laws and drawing policymakers' attention to legal obstacles that need to be eliminated. The standards in force for onsite hydrogen production via water electrolysis, hydrogen storage, both liquid and gaseous, and refueling protocols are among the numerous topics examined, on an international, European, and Italian level
