This ship includes a ship body, a fuel tank chamber, a stern-side engine room, a bow-side engine room, a main fuel line and a sub-fuel line, and a pump mechanism. The main fuel line connects a fuel tank, a stern-side power generation unit, and a bow-side power generation unit through the bow-side engine room. The sub-fuel line connects at least the fuel tank and the stern-side power generation unit, and is disposed through a section different from the bow-side engine room through which the main fuel line passes. The pump mechanism selectively feeds fuel into the main fuel line or the sub-fuel line from the fuel tank.

A marine vessel and method for carbon capture and sequestration are described. The marine vessel includes a buoyant hull, a cryogenic storage tank within the hull, and a gaseous carbon dioxide loading manifold. The marine vessel also includes a carbon dioxide liquefaction system in fluid communication with the cryogenic storage tank downstream of the carbon dioxide liquefaction system and with the gaseous carbon dioxide loading manifold upstream of the carbon dioxide liquefaction system. Finally, the marine vessel includes a carbon dioxide supercritical system in fluid communication with the cryogenic storage tank. In operation, the marine vessel moves between multiple locations, where gaseous carbon dioxide is onboarded, liquified and stored. Thereafter, the marine vessel transports the liquified carbon dioxide to a location adjacent an offshore geological reservoir. The liquefied carbon dioxide is then pressurized to produce supercritical carbon dioxide, which is then injected directly into the reservoir from the marine vessel.

A power system for an engine that can be used in an aircraft, a marine vessel or a land vehicle has a storage tank containing ammonia. An engine supported on the vehicle is configured to operate using hydrogen gas as fuel. A cracking device in or adjacent the engine receives heat from operation of the engine, e.g., from a compressor or a combustion chamber, and also receives ammonia from the storage tank, and it uses the heat from the engine to dissociate the ammonia to produce hydrogen gas. The cracking device supplies the hydrogen gas to the engine, which has a combustor in which combustion of the hydrogen gas takes place. The energy from the combustion drives the engine so as to provide mechanical energy.

The invention concerns land-based gas turbine plants with a multi-spool gas turbine arrangement for generating electrical power to supply a load (200). The invention comprises at least three spools (10a-10c). Each of the at least three spools (10a-10c) comprises a shaft (11a-11c), a compressor (C1-C3) and a turbine (T1-T3). Each one of the shafts (11a-11c) of the at least three spools (10a-10c) are independently rotatable with respect to each other. The invention further comprises electrical generators (G1-G3) mounted on each of the shafts (11a-11c) of the at least three spools (10a-10c), the output power of the generators being independently controllable and at least 60 percent of a total output power supplied to said load (200) in a form of electrical and rotational power is generated by the at least three generators (G1-G3) in the form of electrical energy.

A watercraft comprising a compressed air propulsion system is shown and described. The watercraft includes at least one propeller operatively connected to an air motor. Storage tanks supply compressed air having a pressure of at least 2000 psi to a pressure regulator that reduces the pressure and supplies air to an air control valve. User controls adjust the air control valve to adjust the flow rate of air to the air motor which in turn adjusts the direction and/or speed of rotation of the propeller. An on-board air compressor energized by a plurality of lithium iron phosphate batteries provides air to the air storage tanks when the pressure falls below a specified value. In certain examples, the electric and air propulsion system is used to replace a fossil fuel engine in an existing watercraft and can remain at sea longer than the existing watercraft.

An engine enclosure for containing a gas turbine engine is provided. An exemplary engine enclosure includes features that improve noise and thermal attenuation, reduce the weight of the enclosure, and provide for more accessible access points to the interior volume of the engine enclosure.
