2 The duration of missions that can be accomplished by unmanned aerial vehicles (UAVs) is limited by the battery or fuel capacity of its constituent UAVs. However, a system of UAVs that is supported by automated refueling bases may support long term or even indefinite duration missions in a near autonomous mode. The UAVs can return to a base, replenish their resources and resume their duties. W...

With the introduction of alternative fuel vehicles into the transportation system, the refueling station location research has been touted in the literature. The flow refueling location problem (FRLP) locates p stations in order to maximize the flow volume that can be accommodated in a road network respecting the range limitations of the vehicles. This paper introduces the hybrid charging stati...

The article investigates the possibility of carrying out verification volumetric liquid meters at place operation and presents procedure for such verification. issues metrological support measuring instruments (MI) aircraft refueling service are considered. data on in EU member states presented.

Among the alternative fuels enabling energy transition, hydrogen-based transportation is a sustainable and efficient choice. It finds application both in light-duty heavy-duty mobility. However, hydrogen gas has unique qualities that must be taken into account when employed such vehicles: high-pressure levels up to 900 bar, storage composite tanks with temperature limit of 85 °C, negative Joule...

As the number of hydrogen refueling stations has increased rapidly in recent times, evaluating their incident training programs for first responders, gained importance. In this study, Delphi method was used investigating programs, and importance consensus analyzed using analytical hierarchy process (AHP). Location operating methods emergency shutdown devices, safety distance, response procedure...
