Embodiments herein relate to a mobile fuel distribution station including a plurality of fuel tanks, one or more fuel pumps arranged to distribute fuel from said fuel tanks to users, a central fuel refill arrangement for refilling of one or more of said plurality of fuel tanks, and a fuel leakage prevention system, a central fuel refill arrangement and a fuel leakage prevention system arranged to prevent leakage from the central fuel refill arrangement, and from any of the plurality of fuel tanks. Other embodiments herein relate to a method and a system for predicting points of time for refilling fuel in one or more such mobile fuel distribution stations.

To provide a transportation system that can transport renewable energy from a power generation facility to an energy consumption location. The system consists of a power generator that generates and stores electricity from a renewable energy, a hydrogen generator that generates hydrogen by electrolysis of water using electricity obtained from the power generator, a methane synthesizer that generates methane by the Sabatier reaction using the hydrogen and a recycled CO.sub.2 as raw materials, and a methane transportation system that transports the methane without emitting CO.sub.2 to the atmosphere, a methane transportation system that transports the methane without emitting CO.sub.2 into the atmosphere, a power generation and carbon capture unit that generates electricity by reacting the transported methane with oxygen and captures CO.sub.2 discharged during the power generation as recycled CO.sub.2, a CO.sub.2 transportation system that transports the recycled CO.sub.2 to the methane synthesis site without emitting CO.sub.2 to the atmosphere.

A system for supplying fuel to an engine of a ship. The system includes a high pressure pump pressurizing a liquefied natural gas (LNG) and supplying the pressurized LNG to the engine, a hydraulic motor driving the high pressure pump and a chamber carrying the high pressure pump and the hydraulic motor. The chamber is substantially free of electric sparks.
