Disclosed is a marine fuel cell-based integrated heat, electricity, and cooling supply system comprising a power supply system and a waste heat recovery system; the power supply system comprises wind turbine generator sets, solar generator sets, and a fuel cell power module; the waste heat recovery system encompasses a turbine power generation module and a lithium bromide refrigeration module; the fuel cell power module is connected to both the turbine power generation module and the lithium bromide refrigeration module; the turbine power generation module is used to generate electricity using waste heat. This approach fully exploits the waste heat from the exhaust gas generated by the fuel cell power module, resulting in a high overall energy utilization rate. The self-consumption electricity and pure hydrogen fuel for the integrated energy supply system can be obtained from solar and wind energy, ensuring low carbon emissions for the entire system.

A containerized battery system can include a container, a framework, battery cells, and an electrical coupling. The container can be installed within and removed from a container space on a vessel. The framework can be situated within the container and can define multiple framework compartments therein. The battery cells can be arranged into battery modules that provide power to the vessel. Each battery module can be removably disposed as a combined unit within a framework compartment. Each battery cell within a battery module can be coupled together in parallel and the multiple battery modules can be coupled together in series. The electrical coupling can be configured to facilitate the recharging of the battery cells while the battery cells are within the container. The containerized battery system can also include a fire prevention system, an environmental control system, and a power management system.

A marine A/C system adapted for rooftop installation on a marine T-top on a marine vessel includes a package water-source heat pump having a DC powered refrigerant compressor, a corrosion resistant evaporator coil, and a water-cooled condenser. The package unit is housed within a fully enclosed protective structural weatherproof enclosure or dome, which may be formed in a disc shape resembling a high-end radar dome. Condenser water supply and return lines are concealed within structural tubing forming the T-top support frame thereby rendering the installation non-obvious. Condensate generated by evaporator coil collects in a drain pan and is removed by a suction fitting installed in the drain which is connected to a venturi fitting disposed in the condenser water line such that condensate is drawn from the dain pan and injected into the condenser water line. By injecting the condensate into the condenser water line the number of lines running to and/or from the T-top mounted package unit and in need of concealment is reduced.

A method for removing internal moisture which tends to collect in the hulls, deck, stringers, transoms, bulkheads, spars, and other boat structures. Air injection bores are formed in the core or other boat structure in the vicinity of unwanted moisture. Pressurized injection air is injected into the bores through a plurality of air injection lines running from a source of pressurized injection air. The temperature of the air being injected into bores is varied as a function of the temperature and/or relative humidity of ambient air at or near the bores.
