Scalable greenhouse gas capture systems and methods

A multi-function nozzle for refueling and exhaust capture, the nozzle comprising:

• a fuel nozzle having a fuel nozzle outer surface, an inner annular fuel inlet passage, an inner annular fuel inlet passage surface, and a moveable inner annulus positioned substantially within a space within the inner annular fuel inlet passage surface;
• an exhaust nozzle having an outer annular exhaust outlet passage circumscribed around the fuel nozzle;
• an exhaust hose coupled to the exhaust nozzle and configured to allow exhaust to flow therethrough to exhaust storage;
• and
• a fuel hose coupled to the fuel nozzle, positioned at least partially within the exhaust hose, and configured to allow fuel to flow therethrough.

A system to supply fuel to and off-load captured exhaust from marine vessels, the system comprising:

• a fuel supply source;
• an exhaust logistics and removal assembly;
• one or more marine vessel bays each positioned to receive one or more marine vessels therein, each marine vessel bay of the one or more marine vessel bays comprising at least one fuel dispenser including:
• a user interface configured to enable a user to:
• (a) select to initiate fueling of a marine vessel,
• (b) select to initiate off-loading of captured exhaust from the marine vessel,
• (c) if fueling of the marine vessel is selected, display one or more of an amount of fuel supplied to the marine vessel, a cost of fuel supplied, an amount of captured exhaust off-loaded, a cost or credit resulting from the amount of captured exhaust off-loaded, user incentives, or user rewards, and
• (d) transact payment for one or more of (1) the fueling of the marine vessel, or (2) off-loading captured exhaust from the marine vessel;
• a multi-function nozzle assembly including:
• an exhaust nozzle having an exhaust passage and an inlet end adapted to engage with a marine vessel exhaust port so as to create a sufficiently airtight seal between the exhaust nozzle and the marine vessel exhaust port and substantially prevent exhaust from leaking during off-loading of the captured exhaust,
• a fuel nozzle located at least partially within and movable along the exhaust passage of the exhaust nozzle, the fuel nozzle adapted to engage a fuel inlet port of the marine vessel for fueling of the marine vessel, and
• a fuel and exhaust conduit comprising:
• a fuel hose connected to the rear end of the fuel nozzle and in fluid communication with the fuel supply source, thereby to supply the fuel to the marine vessel through the fuel nozzle, and
• an exhaust hose having one end portion connected to the exhaust nozzle and another end portion connected to the exhaust removal and logistics assembly, the exhaust hose configured to transport captured exhaust from the exhaust nozzle to the exhaust removal and logistics system;
• and
• a meter configured to measure an amount of fuel transported from the fuel supply source to the marine vessel.

A method for selectively supplying fuel to and off-loading captured exhaust from marine vessels, the method comprising:

• receiving a user selection with respect to a marine vessel, thereby to initiate one or more of a marine vessel fueling operation to the marine vessel or a captured exhaust off-loading operation from the marine vessel, the user selection being received from a user interface associated with one or more marine vessel bays of a marine vessel refueling and exhaust capture station;
• transmitting, via the user interface, a prompt, thereby to engage a fuel nozzle and an exhaust nozzle of a multi-function nozzle assembly of a combined fuel and exhaust dispenser/receiver into a corresponding fuel inlet port and a corresponding exhaust outlet port of the marine vessel;
• prior to initiating one or more of a selected marine vessel fueling operation or captured exhaust off-loading operation:
• determining if the fuel nozzle is in substantially sealed engagement with the corresponding fuel inlet port of the marine vessel, and
• determining if the exhaust nozzle is sealingly engaged with the corresponding exhaust outlet port of the marine vessel;
• and
• if the fuel nozzle and the exhaust nozzle of the multi-function nozzle assembly are sealingly engaged with the corresponding fuel inlet and the corresponding exhaust outlet ports of the marine vessel:
• in response to a user selection to initiate fueling of the marine vessel, pumping a flow of fuel of a selected fuel type from a fuel supply system in fluid communication with the fuel nozzle to a fuel tank of the marine vessel, determining an amount of the fuel pumped into the marine vessel,
• in response to a user selection to off-load captured exhaust, extracting captured exhaust from an exhaust capture device of the marine vessel via the exhaust nozzle, and directing the captured exhaust from the marine vessel to a downstream exhaust holding tank,
• determining an amount of captured exhaust from the marine vessel,
• displaying the amount of the fuel pumped into the marine vessel and the amount of captured exhaust from the marine vessel via the user interface, and
• offering a receipt via the user interface after one or more of (a) fuel has been pumped, or (b) after exhaust has been off-loaded from the marine vessel.
