A transport refrigeration system (TRS) for an enclosed space of a transport unit that includes a ventilation pathway to direct air to flow from the enclosed space. The TRS includes a refrigerant circuit with an evaporator configured to cool the air, and a CO.sub.2 scrubber. The CO.sub.2 scrubber includes a metal organic framework (MOF) configured to adsorb CO.sub.2 from the air in an adsorption mode and is regenerated with ambient air in a regeneration mode. A transport unit includes an enclosed space for storing produce, a ventilation pathway, and a TRS. A method of conditioning an enclosed space of a transport unit includes operating a TRS in a first mode that cools air from the enclosed space and adsorbs, with a MOF in a CO.sub.2 scrubber, CO.sub.2 from the air, and operating the TRS in a second mode that regenerates the MOF with ambient air.

A method for heating a cargo on a watergoing vessel using an energy source (such as a heat source) on another watergoing vessel. The vessels may be underway. The energy may be transferred to the cargo via energy umbilicals configured to carry energy in a transfer fluid. The transfer fluid may be circulated in a cargo heat exchanger configured to move energy into the hot cargo. The energy source on the another watergoing vessel may be a propulsion motor, exhaust heat, or non-propulsion heat source. The method may include heating the hot cargo. The method may also include switching between heat sources when both vessels are configured to heat the hot cargo.
