[0033] Various embodiments of the present disclosure provide a system and a method for optimizing the supply chain of the hydrogen distribution network. The present disclosure enables transporting, distributing, and storing hydrogen to meet requirements at consumption sites, such as but not limited to retailers, refueling stations for fueling vehicles being run on hydrogen as a clean fuel, and other consumers, who may be using hydrogen a source of energy. The present disclosure helps in transporting the hydrogen from the production facility to depots based on a Liquid Organic Hydrogen Carrier molecule (LOHC) technology and from the depots to consumption sites as Compressed Gas Hydrogen (CGH.sub.2). The LOHC technology may enable to transport of 4-5 times more H.sub.2 than Compressed Gas Hydrogen (CGH.sub.2) in a given truck. Further, being liquid at ambient conditions, LOHC is easy to handle, transport, and store using the same infrastructure as liquid fuels. Since one of the chemicals used for storing H.sub.2, i.e., Di-benzyl Toluene DBT, is non-flammable and non-explosive, it has a lower risk than the other, i.e., Toluene, for transportation and storage. The present disclosure helps in finding optimal routes from the depots to the consumption sites, such as refueling stations for vehicles, with the objective of distance minimization and vehicle capacity satisfaction, that cover the daily requirement of all consumption sites, and further include optimizing, dispatch of H.sub.2 on each route and for each consumption sites.
[0034] Referring to
[0035] Considering the above factors, the system and methods of the present disclosure propose to distribute hydrogen from the storage (104) of the production facility (102) to the depots using LOHC supply chain technology and from the depots (106) to the consumption sites (108) using compressed hydrogen supply chain technology, as shown in
[0036] To optimize the supply chain from the depots (106) to consumption sites (108) considering that storage at the consumption sites (108) is to be minimized by daily supply, and the daily requirement of many of the consumption sites (108) shall be less than one full vehicle load. The objective of the optimization shall be to find the optimal quantity of cylinder dispatch each day and for each consumption site (108) for the given time horizon, minimizing the several vehicles in the time horizon specified, and minimizing the capital cost of storage used at the depot and the consumption sites (108). The optimization has to also take into account that the vehicles have a fixed capacity, such as a capacity to carry, for example, 4 cylinders, and a vehicle can travel a limited distance in a day, such as max 450 kilometers in a day. For example, if the distance is under 450 Km, it is considered as a whole day travel.

[0105] At block (806), the method (800) may include transmitting, by the processor (202), instructions for transporting the hydrogenated LOHC molecule in one or more tanker trucks, from the production facility (102) to one or more depots (106).
[0106] At block (808), the method (800) may include dehydrogenating, by the processor (202), at the one or more depots (106), the hydrogenated LOHC molecule to release the hydrogen at low pressure, upon receiving the one or more tanker trucks at the one or more depots (106).
[0107] At block (810), the method (800) may include compressing, by the processor (202), at the one or more depots (106), the released hydrogen and fill the compressed hydrogen in one or more high-pressure tube trailers or flat-bed cylinder cascades.
[0108] At block (812), the method (800) may include determining, by the processor (202), one or more optimal routes for one or more transportation vehicles for distribution of the one or more high-pressure tube trailers or flat-bed cylinder cascades from the one or more depots (106) to one or more retailers or consumption sites (108).
[0109] At block (814), the method (800) may include receiving, by the processor (202), information from the one or more retailers or the consumption sites (108), upon arrival of the one or more transportation vehicles to the one or more retailers or consumption sites (108).
[0110] At block (816), the method (800) may include storing, by the processor (202), at the one or more retailers or the consumption sites (108), the compressed hydrogen in one or more low-pressure tanks or one or more high-pressure buffer cylinders.
[0111] At block (818), the method (800) may include outputting, by the processor (202), information corresponding to an inventory of the one or more low-pressure tanks or one or more high-pressure buffer cylinders at the one or more retailers or the consumption sites (108).

[0113] As shown in
[0114] Bus (920) communicatively couples' processor(s) (970) with the other memory, storage, and communication blocks. Bus (920) can be, e.g., a Peripheral Component Interconnect (PCI)/PCI Extended (PCI-X) bus, Small Computer System Interface (SCSI), USB or the like, for connecting expansion cards, drives, and other subsystems as well as other buses, such a front side bus (FSB), which connects processor (970) to a software system.
[0115] Optionally, operator and administrative interfaces, e.g., a display, keyboard, and a cursor control device, may also be coupled to the bus (920) to support direct operator interaction with a computer system. Other operator and administrative interfaces can be provided through network connections connected through a communication port (960). The external storage device (910) can be any kind of external hard-drives, floppy drives, IOMEGA® Zip Drives, Compact Disc-Read-Only Memory (CD-ROM), Compact Disc-Re-Writable (CD-RW), Digital Video Disk-Read Only Memory (DVD-ROM). The components described above are meant only to exemplify various possibilities. In no way should the aforementioned exemplary computer system limit the scope of the present disclosure.
[0116] Various embodiments of the present disclosure provide a system and a method for optimizing the supply chain of the hydrogen distribution network. The present disclosure enables transporting, distributing, and storing hydrogen to meet requirements at consumption sites, such as but not limited to retailers, refueling stations for fueling vehicles being run on hydrogen as a clean fuel, and other consumers, who may be using hydrogen a source of energy. The present disclosure helps in transporting the hydrogen from the production facility to depots based on a Liquid Organic Hydrogen Carrier molecule (LOHC) technology and from the depots to consumption sites as Compressed Gas Hydrogen (CGH.sub.2). The LOHC technology may enable to transport of 4-5 times more H.sub.2 than Compressed Gas Hydrogen (CGH.sub.2) in a given truck. Further, being liquid at ambient conditions, LOHC is easy to handle, transport, and store using the same infrastructure as liquid fuels. Since one of the chemicals used for storing H.sub.2, i.e., Di-benzyl Toluene DBT, is non-flammable and non-explosive, it has a lower risk than the other, i.e., Toluene, for transportation and storage. The present disclosure helps in finding optimal routes from the depots to the consumption sites, such as refueling stations for vehicles, with the objective of distance minimization and vehicle capacity satisfaction, that cover the daily requirement of all consumption sites, and further include optimizing, dispatch of H.sub.2 on each route and for each consumption sites.
[0117] While considerable emphasis has been placed herein on the preferred embodiments, it will be appreciated that many embodiments can be made and that many changes can be made in the preferred embodiments without departing from the principles of the invention. These and other changes in the preferred embodiments of the invention will be apparent to those skilled in the art from the disclosure herein, whereby it is to be distinctly understood that the foregoing descriptive matter to be implemented merely as illustrative of the invention and not as a limitation.
