Technological processes in which hydrogen is obtained as a by-product of plasma erosion and electrochemical coagulation purification of surface water for the needs of the energy industry and urban water supply, as well as the production of pure highly dispersed aluminium hydroxide for the chemical industry, are considered. It is proposed to expand the accepted classification of hydrogen types by technology, raw material, and type of energy used to produce it by introducing a new conditional "color" category - Silver Hydrogen. The technological map of a typical water treatment cycle of thermal units of a CHP is described and the shortcomings of the reagent chemical coagulation operation in its composition are analyzed. Alternative operations of electrochemical and plasma erosion coagulation purification of surface natural waters are described and a comparative analysis of their energy indicators is provided. The energy released during the combustion of hydrogen, which is released as a by-product in these processes, was calculated and a possible increase in their energy efficiency was analyzed under the conditions of using various coagulant-forming metals. The energy potential of using hydrogen emissions in the process of producing aluminium hydroxide at a chemical industry production plant has been determined. References 45, figures 2, tables 2.
