ENERGY AND ENVIRONMENTAL ANALYSIS OF THERMO-CHEMICAL HYDROGEN PRODUCTION USING SOLAR ENERGY IN THE TERRITORY OF THE REPUBLIC OF UZBEKISTAN UDC: 66.011: 502.174.3: 620.97(075.8)
Abstract
Hydrogen is of great interest as a carrier of clean energy in the global transition to renewable energy sources. Uzbekistan is distinguished by its high solar radiation; therefore, it offers a wide opportunity in the production of hydrogen from solar energy. In this study, an energetic and ecological analysis of hydrogen production from solar energy in Uzbekistan by thermochemical method was carried out in the regions.
In this scientific work, all regions were selected and their solar energy potential was studied. Methods of hydrogen production by solar energy were analyzed and the most suitable two-stage method based on metal oxide was selected. Energy consumed in thermochemical production of hydrogen was determined and the amount of hydrogen produced compared to solar energy was determined.
The following amounts of hydrogen production were determined for different regions of Uzbekistan. For example, the maximum production potential of 10,766 tons in Termiz and the lowest of 10,119 tons in Tashkent was determined. The rest of the regions you have taken in general are between these values. Based on this, a total of 135334 tons of hydrogen produced can replace 2706.68 GW of electricity and 216.54 Mm3 of natural gas.
