A fuel tank comprises a circular column-shaped fuel tank body, a handle, and a first connector. The circular column-shaped fuel tank body is provided so as to be detachably attachable to a fuel-powered device. The handle is formed on one end side in a length direction of the fuel tank body. The first connector is formed on another end side in the length direction of the fuel tank body and configured such that, by installing the fuel tank body to the fuel-powered device, the first connector is connected to a second connector provided at the fuel-powered device so as to enable fuel to be supplied to the fuel-powered device.

A hybrid plug-in battery and hydrogen fuel engine vehicle with swappable modular hydrogen tanks and integrated with solar power generation system synergistically combines the advantages of electric vehicle, the solar powered electric vehicle, and the hydrogen fuel engine vehicle. This combination of battery electric vehicle and hydrogen fuel engine vehicle mitigates the issues of prolong charging time of battery electric vehicle and prohibitive high cost of fuel cell electric vehicle. This hybrid configuration of vehicle is able to take advantages of the electric vehicle charging station infrastructure and the hydrogen charging station infrastructure simultaneously. The introduction of the water electrolysis system into the new structure of the hybrid vehicle enables onboard hydrogen generation; has the advantage of conventional hybrid vehicle, but without using fossil fuel. The swappable hydrogen tanks comprise sensors and wireless communication electronic terminals to be shared by all vehicles.

A work machine, more particularly a wheeled loader, having a cab for the operator of the work machine, wherein the work machine has a drive which can be operated with hydrogen and that one or more tanks for receiving hydrogen are provided, wherein components for receiving the tanks are provided, wherein the tank or tanks are arranged below the cab and, when the work machine is viewed from above, next to the cab of the work machine, wherein the components for receiving the tanks do not have a direct mechanical connection to the cab, and that an armor is provided which partially or completely surrounds the tank.

A swivel working machine includes a swivel base, a prime mover installed in the swivel base, a working device provided at the swivel base, and a support mechanism that supports a fuel cylinder in a rotatable manner around a pivot shaft. The fuel cylinder contains fuel for the prime mover. The support mechanism includes a support rotating body that supports the fuel cylinder and that rotates around the pivot shaft, a rotational-position defining mechanism including a pin that defines a rotational position of the support rotating body around the pivot shaft, and an adjustment mechanism that adjusts a position of the pivot shaft relative to the pin.

A fuel tank comprises a circular column-shaped fuel tank body, a handle, and a lock mechanism. The circular column-shaped fuel tank body is provided so as to be capable of being detachably attached to a fuel-powered device. The handle is formed on one end side in a length direction of the fuel tank body. The lock mechanism is capable of switching between a locked state in which the fuel tank body cannot be removed from the fuel-powered device, and a lock-released state in which the locked state has been released, due to the fuel tank body being rotated in a circumferential direction in a state of being installed to the fuel-powered device.

A portable fuel tank assembly includes a portable fuel tank for holding fuel and a support to be connected to a supporting surface for holding the fuel tank stationary with respect to the supporting surface. The fuel tank has a first quick connector for fluid communication with the fuel in the fuel tank. The support has a second quick connector for mating and providing fluid communication with the first quick connector. The fuel tank and support are configured such that securing the fuel tank in the support simultaneously mates the second quick connector to the first quick connector to provide for fluid communication between the second quick connector and the fuel in the fuel tank. A support for holding a portable fuel tank is also provided.

The present invention relates to a machine, in particular wheel loader, with a cabin for the operator of the machine and with an engine compartment arranged behind the cabin, wherein the machine has a drive, which is operable using hydrogen or using energy obtained from hydrogen and wherein one or more tanks are present for receiving hydrogen, wherein the tank or tanks is/are arranged between the cabin and the rear of the machine in a hydrogen fuel system.

A fuel tank for a generator or the like, wherein the fuel tank includes a rigid outer fuel tank structure and an inner bladder. The outer fuel tank structure includes a longitudinal channel for receiving the inner bladder. End caps are disposed on either end of the outer fuel tank structure, so that the internal bladder may be pulled therein with cables or the like. When the internal bladder needs to be replaced due to damage or corrosion, the end caps are removed and cables may be attached to one end of the damaged internal bladder for pulling it from the outer fuel tank structure. Additionally, a replacement bladder may be attached via cables to the other end of the damaged bladder, so that the replacement bladder is pulled into one end of the outer fuel tank structure while the damaged bladder is being pulled out the other end thereof.

A fuel tank comprises a circular column-shaped fuel tank body, a handle, and a lock mechanism. The circular column-shaped fuel tank body is provided so as to be capable of being detachably attached to a fuel-powered device. The handle is formed on one end side in a length direction of the fuel tank body. The lock mechanism is capable of switching between a locked state in which the fuel tank body cannot be removed from the fuel-powered device, and a lock-released state in which the locked state has been released, due to the fuel tank body being rotated in a circumferential direction in a state of being installed to the fuel-powered device.

A hybrid plug-in battery and hydrogen fuel internal combustion engine vehicle with swappable modular hydrogen tanks and integrated with solar power generation system comprises: a plug-in chargeable battery bank; a hydrogen fuel internal combustion engine; a water electrolysis system; a solar electric power generation system; and multiple modular swappable hydrogen tanks. The hybrid electric vehicle can be electrically charged by using electric charging infrastructure and mechanically charged by swapping hydrogen tanks. The introduction of the water electrolysis system into the new structure of the hybrid vehicle enables onboard hydrogen generation. The swappable hydrogen tanks comprise sensors and wireless communication electronic terminals to be shared by all vehicles.
