A Novel System for Combined Hydrogen Production and Power Generation

• A novel concept of combined hydrogen production andpower generation system based on the combustion ofaluminum in water is explored. The energy conversionsystem proposed is potentially able to provide fourdifferent energy sources, such us pressurized hydrogen,high temperature steam, heat, and work at thecrankshaft on demand, as well as to fully comply withthe environment sustainability requirements.Once aluminum oxide layer is removed, the purealuminum can react with water producing alumina andhydrogen while releasing a significant amount of energy.Thus, the hydrogen can be stored for further use and thesteam can be employed for energy generation or workproduction in a supplementary power system. Theprocess is proved to be self-sustained and to provide aremarkable amount of energy available as work orhydrogen. Furthermore, since the aluminum oxidation iscompletely GHG free and the alumina produced by thereaction can be recycled back to aluminum, the processhas a sustainable environmental management.A preliminary design of the combined hydrogenproduction and power generation unit based on thealuminum combustion in water is proposed and theefficiency of the process is discussed in terms of bothhydrogen production and power generation
