The invention is a power generation system which involves a water-splitting reaction employing metal feedstock to generate heat, hydrogen and metal hydroxide. The heat produced by the power generation system supplies a Heating-Ventilation-Air Conditioning (HVAC) system for heating and cooling building structures, such as homes, kiosks, commercial buildings and greenhouses. The hydrogen gas component produced by the invention is sufficient to fuel a fuel cell vehicle (FCV) and a fuel cell, which provides electricity to an associated building structure. The invention can be located on-site with a building structure and provides a readily available FCV fueling station associated with the building structure where an FCV is located.

A system for producing hydrogen gas, heat and an oxide component using a water splitting process is disclosed. The system involves a dry first chamber containing a passivating-oxide preventing reagent that receives a solid material feedstock and dissolves the solid material feedstock in the passivating-oxide preventing reagent. The passivating-oxide preventing reagent becomes saturated with the solid material in the first chamber and is then transferred to a second chamber without contact with water. In the second chamber, the solid material saturated in the passivating-oxide preventing reagent reacts with the water so as to generate hydrogen gas, an oxide component and heat. Following the reaction, the solid material depleted passivating-oxide preventing reagent and water is recycled to be re-used in the water splitting process.

Methods, systems, and compositions related to the recycling and/or recovery of activating materials from activated aluminum are disclosed. In one embodiment, an aqueous solution's composition may be controlled to maintain aluminum ions dissolved in solution during reaction of an activated aluminum. In another embodiment, aluminum hydroxide containing the activating materials may be dissolved into an aqueous solution to isolate the activating materials.

A process and a device are described for producing high purity and high temperature steam from non-pure water which may be used in a variety of industrial processes that involve high temperature heat applications. The process and device may be used with technologies that generate steam using a variety of heat sources, such as, for example industrial furnaces, petrochemical plants, and emissions from incinerators. Of particular interest is the application in a thermochemical hydrogen production cycle such as the Cu—Cl Cycle. Non-pure water is used as the feed-stock in the thermochemical hydrogen production cycle, with no need to adopt additional and conventional water pre-treatment and purification processes. The non-pure water may be selected from brackish water, saline water, seawater, used water, effluent treated water, tailings water, and other forms of water that is generally believed to be unusable as a direct feed-stock of industrial processes. The direct usage of this water can significantly reduce water supply costs.
