Disclosed are systems and methods having inherent carbon capture and conversion capabilities offering maximum flexibility, efficiency, and economics while simultaneously enabling environmentally and sustainably sound practices. A hybrid thermochemical cycle couples staged reforming with hydrogen production and residue chlorination. The residues of the upgrading are chlorinated, metals of interest are removed and bulk material is re-mineralized. Through the residue chlorination process, various metals including rare earths are concentrated and extracted. Energy is retained through chemical synthesis such as hydrocarbon and metal and non-metal chloride production. Produced chemicals are later exploited by redox reactions in the operation of an integrated gasification flow battery.
