    Opis:
    The article presents idea of installation to energy storage in the form of hydrogen - Power to Gas (P2G). The results of laboratory tests carried out at the Silesian University of Technology in the Institute of Power Engineering and Turbomachinery (IMiUE), covering selected aspects of hydrogen generators most frequently used in these types of installations are presented. The influence of water conductivity and temperature during continuous operation of the electrolyzer at constant current value and in operation at variable current on the efficiency of the tested devices are shown. A hydrogen generator equipped with two AEM electrolyzers with a performance of 0.5 Nm3H2/h and a generator containing four PEM electrolyzers connected in series, with a maximum performance of 1.58 Ndm3/min were tested. The efficiency characteristics of the electrolysis process, efficiency of the electrolyzers and changes in the resistance values for both types of electrolyzers were presented. Calculations to estimate effect of temperature change on the efficiency characteristic of AEM electrolyzers were also made.

    Opis:
    Energy efficiency improvement and ecological safety of heat power plants are urgent problems, which require scientifically grounded approaches and solutions. These problems can be solved partly within the presented heat-and-power cycles by including contact energy exchange equipment in the circuits of existing installations. A significant positive effectis obtained in the contact energy exchange installations, such as gas-steam installation ‘Aquarius’ and the contact hydrogen heat generator that also can use hydrogen as a fuel. In these plants, the efficiency increases approximately by 10–12% in comparison with traditional installations, and the concentration of toxic substances, such as nitrogen oxides and carbon monoxide in flue gas can be reduced to 30 mg/m3 and to 5 mg/m3, respectively. Moreover, the plants additionally ‘generate’ the clean water, which can be used for technical purposes.

    Opis:
    In the dumps of metallurgical enterprises of Kazakhstan about 700 million tons of waste products are generated annually, and are polluting the atmosphere and the soil. The concentration of valuable components in waste products are no lower than in natural resources. The reserves of coal in the Ekibastuz basin are estimated to be more than a billion tons, and almost half of this is made up of ash. Every year, up to 30 million tons of ash-cinder waste is generated, which presents a serious threat to nature. Gallium and germanium concentrations in dumps are approximately 200 grams per ton, which is comparable to the content in coal before processing. The current research aims at creating a unit to obtain hydrogen-enriched water gas from Ekibastuz coal, with the production of zinc, gallium and germanium sublimates, copper-containing cast iron, slag wool and cast stone, through the joint processing of zinc-rich slag and ash-cinder wastes from thermal power plants. To achieve this, we used previous methods of extreme energy saving and a new method, the smelt layer with inversion phase. Experimental results from the “reactor inversion phase – rotary kiln” (RIPh) unit, which processed zinc-germanium contained slag, showed the potential to extract germanium from zinc sublimates, to reduce iron to the form of cupreous cast iron, and to obtain combustible gases and smelt suitable for slag-wool production. Calculations performed on the joint processing of Ekibastuz coal and zinc-rich slag using the proposed unit“ reactor of inversion phase–rotary kiln–gas generator” showed it can obtain hydrogen-enriched watergas, along with the extraction of valuable components of primary raw material.
