“…Thus, sustainable alternatives with hydrogen as the energy carrier, obtained from renewable energy [13], are being considered for urban mobility in electric unipersonal vehicles [14][15][16][17][18]. Hydrogen-powered unipersonal electric vehicles offer advantages such as fast charging, long range and low on-board pressure.…”

The percentage of the population in urban areas has increased by ten points from 2000 (46%) to 2020 (56%); it is expected to reach up to 70% by 2050. This undoubtedly will encourage society to use alternative transports. On the other hand, the widespread fear of pandemics seems to be here to stay, and it is causing most people to leave public transport to use private cars, and a few have chosen unipersonal electric vehicles. As a consequence, the decision of using private cars negatively affects the air quality, and consequently urban population health. This paper aims to demonstrate a sustainable solution for urban mobility based on a hydrogen powered unipersonal electric vehicle, which, as shown, provides great advantages over the conventional battery powered unipersonal electric vehicle. To show this, the authors have developed both vehicles in comparable versions, using the same platform, and ensuring that the total weight of the unipersonal electric vehicle was the same in both cases. They have been subjected to experimental tests that support the features of the hydrogen-based configuration versus the battery-based one, including higher specific energy, more autonomy, and shorter recharge time.

“…In this case, Japanese hydrogen fueling regulation JPEC-S 0003(2012) was applied to refuel the motorcycle after the fueling safety has been confirmed [8]. Furthermore, a new hydrogen fueling method for fuel cell motorcycles incorporating compressed hydrogen storage systems is under development [11]. To make fuel cell motorcycles commercially available all over the world, it is important to establish appropriate technical regulations for these vehicles.…”

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.

“…Honda has conducted original research on hydrogen refueling technology (4)- (7) , and the MC Formula refueling method, which enables real-time flexible control of the pressure ramp rate even when the precooled hydrogen temperature fluctuates, was adopted in the 2016 edition of SAE J2601 (1) . This enabled shortening the refueling time by up to approximately 30%.…”

A new real-time pressure loss compensation method was developed for hydrogen refueling stations to increase fuel cell vehicle driving ranges. Pressure loss coefficient measurement every refueling enabled to distinguish the conditions of each vehicle and the station. A time-lag pressure loss measuring method was utilized to accurately get the pressure loss without the vehicle's data. The vehicle tank pressure was accurately estimated only from the station's measurement data. As a result, the vehicle's SOC was enhanced by an average of 4.6%
