Attorney Docket No: FEG-003WO ENERGY GENERATING DEVICES, SYSTEMS, AND METHODS OF USE THEREOF CROSS REFERENCE TO RELATED APPLICATIONS [0001] This application claims the benefit of, and priority to, United States Provisional Application Serial No.63/422,704, filed on November 4, 2022, the contents of which are incorporated by reference herein in their entirety. BACKGROUND [0002] Climate change presents a major threat to the environment and to human society. Fossil fuels are used as the main energy source throughout the world, and while these fuels are highly energy-dense, cheap, and easy to handle, their combustion results in high CO₂ emissions, which is one of the primary drivers of climate change. [0003] Renewable energy sources such as solar energy, wind energy, hydropower, and geothermal energy have the potential to provide the needed energy to reduce or replace fossil fuel dependence. Renewable energy technologies have developed rapidly in recent years and have become economically competitive with fossil fuels. As a result of technological development, improved economics, and multiple large-scale renewable energy projects around the globe, today almost 10 percent of humanity’s energy needs are met by renewable sources. [0004] While renewable energy provides a suitable solution for the production of electricity and can directly feed power grids or power consumers, there are still many other energy consumers that cannot connect directly to power grids or are geographically prohibitively far from renewable resources. For these applications, there needs to be a sufficiently energy-dense, cheap, stable, and safe method for storing and transporting renewable energy from the point of generation (e.g., a solar photovoltaic plant or wind turbine in a remote location) to the point of use. The geographical locations where renewable energy sources are most efficiently and easily captured (e.g., wide-open fields) are often not near metropolitan centers - some entire countries with an interest in utilizing renewable energy sources have few viable options. The maritime shipping industry, for example, is a large energy consumer, and because ships require power as they travel across large bodies of water, a stationary power source is not possible. Renewable energy can also not be harvested in situ for these ships due to low area footprint and the intermittent nature of solar and wind, causing operational challenges. 1 IPTS/125341820.1 Attorney Docket No: FEG-003WO SUMMARY [0005] Provided herein are methods, systems, and devices appropriate in the use of alternative carbon-neutral fuel that is energy dense, safe, and easily transportable. Currently, energy transportation is mostly conducted by transporting fossil fuels from the source well or gas field to the destination in the form of raw materials (coal, oil, etc.) or as product fuels after being refined. Electrochemical batteries (e.g., Li-ion) simply do not have the energy density or price point to fulfill a similar role for the renewable energy transition. Several alternatives exist presently, the most promising being various forms of storing and transporting hydrogen (H ₂ ), which can be produced by splitting of water using renewable electricity (e.g. via electrolyzers); however, the most common methods for storing hydrogen - gaseous or liquid hydrogen or as liquid ammonia or methanol - have numerous operational challenges, including high cost and low volumetric energy density compared to liquid hydrocarbons; and high explosivity or flammability, making them unsafe. In fact, across the United States, vehicles carrying hydrogen are not permitted in certain high-traffic areas. There is thus a critical need for making renewable energy more accessible to end-users that are currently reliant on fossil fuels. The ability to transport renewable energy from the point of generation to the point of use is required to solve that need. [0006] Fortunately, renewable energy is already being shipped around the world in a high- energy density, stable, and cost-effective form-factor as aluminum metal. Aluminum has a volumetric energy density that is double that of liquid hydrocarbons, ten times that of liquid hydrogen, and five times that of other liquid hydrogen carriers like ammonia and methanol. Moreover, the production of aluminum via the standard Hall-Heroult process consumes electricity to reduce aluminum oxide to pure aluminum, making it an effective store of that electrical energy input. If renewable energy sources are used to supply that energy, the resultant aluminum is storing renewable energy that can later be released by oxidation. One method for releasing said energy is the reaction of aluminum with water, enabling the release of heat and hydrogen gas by either/both of the following chemical reactions: Al + 2 H ₂ O → 1.5 H ₂ + AlO(OH) + Q _reaction (Reaction 1) Al + 3 H ₂ O → 1.5 H ₂ + Al(OH) ₃ + Q _reaction (Reaction 2) [0007] By shipping aluminum instead of hydrogen via the aforementioned alternative methods, users can save 5-10 times on volume and up to 50% on weight. Aluminum metal is also 2 IPTS/125341820.1 Attorney Docket No: FEG-003WO significantly more stable and safe compared to these alternative methods due to the naturally occurring oxide layer that forms on the aluminum surface upon exposure to oxygen. This allows for hydrogen and heat to be produced on demand, far from the source of production. Technologies that enable this process, which are discussed herein, are critical to enabling the transportation of renewable energy, thereby making the renewable energy transition more practical and effective.

[00202] Regardless of the specific applications of the devices, systems, and methods provided and described herein, once the aluminum-reaction is complete, the AlOOH may be collected at a central processing facility and purified to a suitable degree for resale back into the global supply chain of AlOOH, Al(OH) ₃ , or even Al ₂ O ₃ , which is an easily produced derivative of AlOOH via calcination. This resale is depicted as the last step in FIG.4. As shown in FIG.5, AlOOH may also be fed directly into the primary aluminum smelting process directly by first being calcined to Al ₂ O ₃ and then electrochemically reduced via the standard Hall-Heroult process or similar. In a global supply chain sense, this step essentially “recharges” the material, storing the substantial 63 IPTS/125341820.1 Attorney Docket No: FEG-003WO amount of energy per unit mass that can later be extracted for the variety of applications described here previously. FIG.4 shows one such application where aluminum scrap is collected, converted into a modular, containerized fuel pack, which is then distributed to some end-use application where that energy can be extracted and utilized. In this illustrated application, the fuel packs are loaded onto a vessel, which then uses the contained energy for powering propulsion, auxiliary power, heat, and the remainder of its onboard energy needs. As shown in FIG.5, this same scenario and similar applications can instead be powered by primary aluminum smelted using renewable energy. While these Figures show maritime shipping as an application of this aluminum energy storage concept, numerous other applications exist as well, which would benefit from the delivery of aluminum as an energy carrier.

The system can produce 970 kg of hydrogen and a total of 75 MWh thermal energy with a power output of 0.4 - 5 MW. After the energy is spent/the aluminum is consumed, the system is unloaded from the shipping vessel and transported back for the recycling process 64 IPTS/125341820.1 Attorney Docket No: FEG-003WO that includes recapturing the catalyst, extracting the AlOOH and/or Al(OH) ₃ by-product, and reloading with new aluminum.

As soon as the system is delivered to the ammonia synthesis facility and secured in position, an operator connects a water hose that is fed by a water pump. The operator also connects hydrogen and steam hoses to the system’s outlets that are connected to the production facility. Then a valve that controls the water inlet is opened and closed periodically allowing water to flow into the reactor to start and control the aluminum- water reaction. The system can produce 970 kg of hydrogen and a total of 75 MWh thermal energy with a power output of 0.4 - 5 MW. After the activated aluminum is spent, the system is transported back for the recycling process that includes recapturing the catalyst, extracting AlOOH and/or Al(OH) ₃ by-product, and reloading with new aluminum. [00208] Example 3. Providing hydrogen and steam to an aluminum smelting facility [00209] This example describes a system for producing energy in the form of hydrogen and heat, on demand for the smelting or recycling of aluminum. The system is configured with an internal 30 m ³ reactor that includes 20 tons of aluminum, pretreated with liquid-metal based catalyst and other supporting subsystems. The system is in the general shape of a shipping container 20 ft length, 8 ft width and a height or 8 ft and 6 in and has the ability to be mounted and transported by any type of container supporting mode of transpiration. As soon as the system is delivered to the aluminum production facility and secured in position, an operator connects a water hose that is fed by a water pump. The operator also connects hydrogen and steam hoses to the system’s outlets that are connected to the aluminum production facility. Then a valve that controls the water inlet is opened allowing water to flow into the reactor to start the aluminum-water reaction. The system can produce 1940 kg of hydrogen and a total of 150 MWh thermal energy with a power output of 0.4 - 10 MW. As soon as the energy is spent, the system 65 IPTS/125341820.1 Attorney Docket No: FEG-003WO is transported back for the recycling process that includes recapturing the catalyst, extracting AlOOH and/or (Al(OH) ₃ ), and reloading with new aluminum. [00210] Example 4. Providing hydrogen and steam to an electricity production device [00211] This example describes a system for producing energy in the form of hydrogen and heat, on demand for electricity generation. The system is configured with an internal 30 m ³ reactor that includes 20 tons of aluminum, pretreated with liquid-metal based catalyst and other supporting subsystems. The system is in the general shape of a shipping container 20 ft length, 8 ft width and a height of 8 ft 6 in and has the ability to be mounted and transported by any type of container-supporting mode of transportation. As soon as the system is delivered to the electricity production unit and secured in position, an operator connects a water hose that is fed by a water pump. The operator also connects hydrogen and steam hoses to the system’s outlets that are connected to the electricity production unit. Then a valve that controls the water inlet is opened allowing water to flow into the reactor to start the aluminum-water reaction. The system can produce 1940 kg of hydrogen and a total of 150 MWh thermal energy with a power output of 0.4 - 10 MW. After the energy is spent/the aluminum is consumed, the system is transported back for the recycling process that includes recapturing the catalyst, extracting AlOOH and/or Al(OH) ₃ by-product, and reloading with new aluminum. [00212] Example 5. Providing hydrogen and steam for backup power generation applications [00213] This example describes a system for providing backup energy for electricity generation, by producing energy in the form of on-demand hydrogen and heat. The system is configured with an internal 30 m ³ reactor that includes 20 tons of aluminum, pretreated with liquid-metal based catalyst and other supporting subsystems. The system is in the general shape of a shipping container 20 ft length, 8 ft width and a height of 8 ft 6 in and has the ability to be mounted and transported by any type of container-supporting mode of transportation. When the system is delivered to the electricity production unit it may be stored onsite, unconnected in stasis indefinitely, until the stored energy is needed, or it may be connected immediately, but left in stasis until the energy is needed. To connect the system, either immediately upon arrival or at a later time when the energy is needed, the system is moved into position and an operator connects a water hose that is fed by a water pump. The operator also connects hydrogen and steam hoses to the system’s outlets that are connected to the electricity production unit. When energy is needed from the system, a valve that controls the water inlet is opened allowing water to flow 66 IPTS/125341820.1 Attorney Docket No: FEG-003WO into the reactor to initiate, or continue, the aluminum-water reaction. The system can produce 1940 kg of hydrogen and a total of 150 MWh thermal energy with a power output of 0.4 - 10 MW. After the energy is spent, the system is transported back for the recycling process that includes recapturing the catalyst, extracting AlOOH and/or Al(OH) ₃ by-product, and reloading with new aluminum. [00214] Example 6. Providing process gas to an electricity production unit [00215] This example describes a system for producing energy in the form of hydrogen and heat on demand for electricity generation. The system is configured with an internal 30 m ³ reactor that includes 20 tons of aluminum, pretreated with liquid-metal based catalyst and other supporting subsystems. The system is in the general shape of a shipping container 20 ft length, 8 ft width and a height of 8 ft 6 in and has the ability to be mounted and transported by any type of container-supporting mode of transportation. As soon as the system is delivered to the electricity production unit and secured in position, an operator connects a water hose that is fed by a water pump. The operator also connects a process gas hose to the system’s process gas outlet that is connected to a process gas inlet of the electricity production unit. Then a valve that controls the water inlet is opened allowing water to flow into the reactor to start the aluminum-water reaction. The resulting process gas, comprising a mixture of steam and hydrogen, is directly fed into the electricity production unit without first separating the two gasses in the system. The system can produce 1940 kg of hydrogen and a total of 150 MWh thermal energy with a power output of 0.4 - 10 MW. After the energy is spent, the system is transported back for the recycling process that includes recapturing the catalyst, extracting AlOOH and/or Al(OH) ₃ by-product, and loading of new aluminum. [00216] Example 7. Providing process gas to an alumina refinery with downstream separation of hydrogen gas and steam [00217] This example describes a system for producing energy in the form of hydrogen and heat, on demand for the refining of alumina. The system is configured with an internal 30 m ³ reactor that includes 20 tons of aluminum, pretreated with a liquid metal-based catalyst, and other supporting subsystems. The aluminum may optionally be derived from locally collected aluminum scraps. The system is in the general shape of a shipping container 20 ft length, 8 ft width and a height or 8 ft and 6 in and has the ability to be mounted and transported by any type of container-supporting mode of transportation. As soon as the system is delivered to the 67 IPTS/125341820.1 Attorney Docket No: FEG-003WO alumina refining facility and secured in position, an operator connects a water hose that is fed by a water pump. The operator also connects a process gas hose to the system’s process gas outlet that is connected to a process gas inlet of the alumina refining facility. Then a valve that controls the water inlet is opened allowing water to flow into the reactor to start the aluminum-water reaction. The resulting process gas, comprising a mixture of steam and hydrogen, is directly integrated into the facility’s heating systems without first separating the two gasses. The heat from the steam is extracted externally from the system, using a heat exchanger in the facility, and applied to one or more processes, such as bauxite digestion. The resulting steam condensate is appropriately routed and merged with the water supply inlet. The remaining process gas is significantly enriched in hydrogen, which is then fed to another process downstream requiring hydrogen. The system can produce 1940 kg of hydrogen and a total of 150 MWh thermal energy with a power output of 0.4 - 10 MW. After the energy is spent, the system is transported back for recycling, including recapturing of the catalyst, extraction of AlOOH and/or Al(OH) ₃ by- product, and loading of new pre-treated aluminum. AlOOH and/or Al(OH) ₃ by-product may also be repurposed as feedstock for alumina production as an alternative to bauxite digestion. [00218] Example 8. Extracting energy from waste stream [00219] This example describes a system for extracting energy from used post-consumer consumables and segregated aluminum waste within the general waste stream. The system comprises a 0.2-1 MW reactor that includes aluminum pretreated with a liquid metal-based catalyst located near a waste landfill. The aluminum is derived from locally sourced aluminum scraps. Steam and hydrogen produced by the reactor upon addition of water to the pre-treated aluminum is used to generate electricity. After the energy extraction is complete, the system is transported back for recycling, including recapturing of the catalyst and extraction of AlOOH and/or Al(OH) ₃ by-product. [00220] Example 9. Extracting energy from aluminum scraps [00221] This example describes a system for extracting energy from waste aluminum scraps generated by an aluminum smelter. Steam and hydrogen produced by the reactor upon addition of water to the pre-treated aluminum is used for various industrial applications within the facility requiring steam and/or hydrogen. As soon as the energy extraction is complete, the system is transported back for recycling, including recapturing of the catalyst and extraction of AlOOH and/or Al(OH) ₃ by-product. 68 IPTS/125341820.1 Attorney Docket No: FEG-003WO EQUIVALENTS AND SCOPE [00222] In the claims articles such as "a," "an," and "the" may mean one or more than one unless indicated to the contrary or otherwise evident from the context.
