Comparative study of regulations,codes and standards and practices on hydrogen fuelling stations

This work deals with a comparative study of regulations, codes and standards for hydrogen fuelling station dedicated for light duty land vehicles in the following countries: United States (California), United Kingdom, Italy, Germany, Canada, Sweden, Norway, Denmark and Spain.The following technical components of a hydrogen fuelling station are included in the scope of the study: the hydrogen storage systems (cryogenic or compressed gases) and buffer storage, the compressor stations, the high pressure buffer storage, the cooling systems for hydrogen, the dispensing equipments and the dispensing area. The hydride storage, the pipelines, on site production and the hydrogen vehicle have been excluded.The analysis, performed in September 2014 in a report from INERIS DRA-14-141532-06227C BENCHMARK STATIONS-SERVICE HYDROGENE, is based on documents collected by bibliographic review and information obtained through a questionnaire sent to authorities and IA HySafe [1] members in the above mentioned countries.This paper gives a synthesis of the regulations and on permitting process in the different studied countries (including the new European Directive on the deployment of alternative fuels infrastructure in Europe [2]), it develops the required safety barriers in the different parts of a fuelling station and specially for the dispensing area, gives an overview of the different approaches for safety distances and processes to obtain licences to operate.     

Quality practices in design organizations

Design organizations play a major role in the construction industry: they are the media that transfer the requirements of the client to the contractor and ensure that they are met. Thus they need to provide a high quality of service to ensure that their client's project achieves the best possible standards of cost, time and quality. Seventy quality practices (QP) were identified as having a bearing on the quality of service provided by the local design organizations. These quality practices were grouped into fifteen sections termed quality sections (QS). The prevalence of these practices among the local design organizations was surveyed and determined. The results indicate a significant need for improvement in the quality sections ‘working relationship’, ‘employee training and education’, and ‘performance quality audit’. The study reveals the need for the establishment of a design code, and evaluation standards for local design organizations.
