Base Load

Selected solar-hybrid power plants for operation in base-load as well as midload were analyzed regarding supply security (dispatchable power due to hybridization with fossil fuel) and low CO2 emissions (due to integration of thermal energy storage). The power plants were modeled with different sizes of solar fields and different storage capacities and analyzed on an annual basis. The results were compared to each other and to a conventional fossil-fired combined cycle in terms of technical, economical, and ecological figures. The results of this study show that in comparison to a conventional fossil-fired combined cycle, the potential to reduce the CO2 emissions is high for solar-thermal power plants operated in base-load, especially with large solar fields and high storage capacities. However, for dispatchable power generation and supply security it is obvious that in any case a certain amount of additional fossil fuel is required. No analyzed solar-hybrid power plant shows at the same time advantages in terms of low CO2 emissions and low levelized electricity cost (LEC). While power plants with solar-hybrid combined cycle (SHCC®, Particle-Tower) show interesting LEC, the power plants with steam turbine (Salt-Tower, Parabolic Trough, CO2-Tower) have low CO2 emissions.

Electrical Demand

One method of reducing atmospheric CO2 emissions in the transportation sector is the replacement of conventional fossil fuel-based vehicles with Electric Vehicles (EVs). However, fossil fuels are still the primary source of electricity production in many regions and the utilization of EVs in such regions increases the electricity demand because of battery charging. This results in increased burning of fossil fuels by thermal power plants and therefore can offset savings in CO2 emissions resulting from the adoption of EVs. In this paper, we consider a scenario where all fossil fuel-based conventional vehicles are replaced by EVs and then estimate the net CO2 emission savings resulting from the adoption of EVs in a region where electricity is primarily supplied by thermal plants. Only emissions generated during the operational phase of vehicle use are considered; emissions during the production phase are not considered. The region under consideration is Madeira, Portugal where thermal plants account for 80% of the total electricity produced. Our findings suggest that although EVs have huge potential to save CO2 emissions, a substantial amount of the savings can be offset due to the increased burning of fossil fuels by thermal plants to meet the electrical demand of charging batteries.

The existing issues during the combustion of Kazakh coal from the Ekibastuz basin in the Omsk energy system are noted. The environmental problems of coal generation in Omsk are outlined. The possibility of transferring the Omsk coal-fired thermal power plants to the combustion of domestic coals is considered. The options for increasing the efficiency of using solid fossil fuel in the production of electric and thermal energy are given. The existing problem of storing ash and slag wastes obtained by burning high-ash Ekibastuz coals is noted. The transfer of the Omsk CHPPs to the combustion of brown coal from the Kansk-Achinsky deposit, provided that highly effective environmentally friendly technologies are used It is noted that the technology of combustion of fuels in a circulating fluidized bed (CFB) has been industrially developed and implemented in power boilers. The results of operation of the first in Russia CFB boiler of unit No. 9 with a capacity of 330 MW at the Novocherkasskaya SDPP are presented
