On-board storage and handling of hydrogen continues to be a major challenge on the road to the widespread commercialization of hydrogen fuel cell vehicles. QUANTUM Fuel Systems Technologies WorldWide, Inc. (QUANTUM) is developing a number of advanced technologies in response to the demand by its customers for compact, lightweight, safe, robust, and cost-effective hydrogen fuel systems. QUANTUM approaches hydrogen storage and handling as an engineered system integrated into the design of the vehicle. These engineered systems comprise advanced storage, regulation, metering, and electronic controls developed by QUANTUM. In 2001, QUANTUM validated, commercialized, and began production of lightweight compressed hydrogen storage systems. The first commercial products include storage technologies that achieved 7.5 to 8.5 percent hydrogen storage by weight at 350 bar (5,000 psi). QUANTUM has also received German TUV regulatory approval for its 700 bar (10,000-psi) TriShield10™ hydrogen storage cylinder, based on hydrogen standards developed by the European Integrated Hydrogen Project (EIHP). QUANTUM has patented an In-Tank Regulator for use with hydrogen and CNG, which have applications in both fuel cell and alternative fuel vehicle markets. To supplement the inherent safety features designed into the new 700 bar storage tank, QUANTUM’s patented 700 bar In-Tank Regulator provides additional safety by confining the high pressure in the tank and allowing only a maximum delivery pressure of 10 bar (150-psi) outside the storage system. This paper describes initial applications for these hydrogen fuel systems, which have included fuel cell automobiles, buses, and hydrogen refueling stations.

Technical Regulations

Hydrogen fuel cell vehicles are expected to play an important role in the future and thus have improved significantly over the past years. Hydrogen fuel cell motorcycles with a small container for compressed hydrogen gas have been developed in Japan along with related regulations. As a result, national regulations have been established in Japan after discussions with Japanese motorcycle companies, stakeholders, and experts. The concept of Japanese regulations was proposed internationally, and a new international regulation on hydrogen-fueled motorcycles incorporating compressed hydrogen storage systems based on this concept are also established as United Nations Regulation No. 146. In this paper, several technical regulations on hydrogen safety specific to fuel cell motorcycles incorporating compressed hydrogen storage systems are summarized. The unique characteristics of these motorcycles, e.g., small body, light weight, and tendency to overturn easily, are considered in these regulations.

This paper shows the results of an in-depth techno-economic analysis of the public transport sector in a small to midsize city and its surrounding area. Public battery-electric and hydrogen fuel cell buses are comparatively evaluated by means of a total cost of ownership (TCO) model building on historical data and a projection of market prices. Additionally, a structural analysis of the public transport system of a specific city is performed, assessing best fitting bus lines for the use of electric or hydrogen busses, which is supported by a brief acceptance evaluation of the local citizens. The TCO results for electric buses show a strong cost decrease until the year 2030, reaching 23.5% lower TCOs compared to the conventional diesel bus. The optimal electric bus charging system will be the opportunity (pantograph) charging infrastructure. However, the opportunity charging method is applicable under the assumption that several buses share the same station and there is a “hotspot” where as many as possible bus lines converge. In the case of electric buses for the year 2020, the parameter which influenced the most on the TCO was the battery cost, opposite to the year 2030 in where the bus body cost and fuel cost parameters are the ones that dominate the TCO, due to the learning rate of the batteries. For H2 buses, finding a hotspot is not crucial because they have a similar range to the diesel ones as well as a similar refueling time. H2 buses until 2030 still have 15.4% higher TCO than the diesel bus system. Considering the benefits of a hypothetical scaling-up effect of hydrogen infrastructures in the region, the hydrogen cost could drop to 5 €/kg. In this case, the overall TCO of the hydrogen solution would drop to a slightly lower TCO than the diesel solution in 2030. Therefore, hydrogen buses can be competitive in small to midsize cities, even with limited routes. For hydrogen buses, the bus body and fuel cost make up a large part of the TCO. Reducing the fuel cost will be an important aspect to reduce the total TCO of the hydrogen bus.
