System for Offshore Production of Fuel

A system for offshore production of fuel comprising:

• an offshore marine platform;
• a first pump to transfer by pumping the produced liquified ammonia from marine platform to floating storage unit;
• a water purification unit on the marine platform, the water purification unit having a purified water outlet and a seawater inlet, the seawater inlet in fluid communication with one or more seawater intakes to draw in seawater for purification;
• a hydrogen production unit on the marine platform, the hydrogen production unit having a hydrogen gas outlet and a purified water inlet, the purified water inlet in fluid communication with the purified water outlet of the water purification unit;
• a nitrogen production system on the marine platform, the nitrogen production system having a nitrogen gas outlet;
• an ammonia production system on the marine platform, the ammonia production system having a hydrogen gas inlet in fluid communication with the hydrogen gas outlet of the hydrogen production unit, a nitrogen gas inlet in fluid communication with the nitrogen gas outlet of the nitrogen production unit, and an ammonia gas outlet;
• a liquefaction system in fluid communication with the ammonia gas outlet of the ammonia production unit, the liquefaction system having a liquified ammonia outlet;
• a plurality of offshore wind turbines disposed to provide electricity to at least one of the hydrogen production unit, the nitrogen production system or the ammonia production system;
• a liquified ammonia floating storage unit moored adjacent the marine platform and in fluid communication with the liquified ammonia outlet of the liquefaction system.

A method for offshore production of fuel comprising:

• pumping seawater to a water purification system mounted on an offshore marine platform affixed to the seabed;
• utilizing the water purification system to at least partially purifying the pumped seawater to yield purified water;
• pumping air to a nitrogen production system mounted on an offshore marine platform;
• utilizing the nitrogen production system to produce gaseous nitrogen from the pumped air;
• utilizing a hydrogen production system mounted on the offshore marine platform to generate gaseous hydrogen from the purified water;
• and
• utilizing an ammonia production system mounted on the offshore marine platform to produce gaseous ammonia from the gaseous nitrogen and gaseous hydrogen.
