Embodiments of systems and methods for transporting fuel and carbon dioxide (CO.sub.2) in a dual-fluid vessel thereby minimizing transportation between locations are disclosed. In an embodiment, the dual-fluid vessel has an outer shell with two or more inner compartments, positioned within the outer shell, including a first inner compartment for storing CO.sub.2 and a second inner compartment for storing fuel. The dual-fluid vessel may connect or attach to a transportation vehicle to thereby allow transportation of the fuel and CO.sub.2. Insulation may provide temperature regulation for the fuel and CO.sub.2 when positioned in the respective first and second inner compartments. One or more ports having an opening in and through the outer shell and a fluid pathway to one or more of the first inner compartment or the second inner compartment may provide fluid communication through the opening and fluid pathway for loading/offloading the fuel and/or CO.sub.2.

A vehicle mounted monitoring system for removable propane tanks includes a propane tank holding system, at least one tank measuring sensor, a hard-wired vehicular power connection, a main control module, and a vehicular display module. The propane tank holding system includes at least one resting bracket so that a propane tank can be placed and secured. The tank measuring sensor is operatively coupled to the resting bracket to measure the remaining amount of liquid in the propane tank. The hard-wired vehicular power connection is electrically connected to the tank measuring sensor for continuous operation. The tank measuring sensor is electronically connected to the vehicular display module through the main control module so that the user can be informed.

A hydrogen storage apparatus of a vehicle driven by a fuel cell comprising hydrogen storage tank holding apparatuses 8, 9 having pluralities of hydrogen storage tank insert parts 10. When the replaceable hydrogen storage tank 20 is inserted into the hydrogen storage tank insert part 10, the hydrogen outflow part 28 of the hydrogen storage tank 20 is coupled with the hydrogen inflow part 23 connected to the fuel cell 40. The grippable handle 24 is formed at the end portion of the hydrogen storage tank 20. A work of inserting the hydrogen storage tank 20 into the hydrogen storage tank insert part 10 and a work of coupling the hydrogen inflow part 23 and the hydrogen outflow part 28 is performed by gripping the handle 24.
