Hydrogen is an attractive energy carrier due to its potentially high energy efficiency and low generation of pollutants, which can be used for stationary power generation in Uzbekistan. However, hydrogen is not readily available in sufficient quantities and the production cost is still high. Solar energy plays an important role in the reduction of the hydrogen production cost, meeting energy demand with rational using the fossil fuels for human beings and in relieving global warming. This work evaluates a possible alternative to producing hydrogen and power based on different reforming and gasification technologies with various primary energy sources namely natural gas, coal and biomass. In the integration of solar energy into the developed systems, the concentrated solar heat is utilized to drive the high-endothermic reforming and gasification with carbon looping. In so doing, the process increases the utilization of CO2 and reduces the carbon emissions as well as saves the extra fuel consumption for combustion, leading to high efficiency of energy utilization. To manifest the feasibility of such a design, the thermodynamics, environment, and economy are assessed in this study. Compared with traditional standalone systems hydrogen and power generation, the designed systems can save energy input, while reducing CO2 emissions.
