“…The total power output from the cycle was calculated from the following equation: W = W turbine − W compressor (28) where W turbine is the power generated by the gas turbine's generator, and W compressor is the power consumed by the air compression unit. In turn, the power consumed by the air compressor, W compressor , was found from the following equation: W = Heat flow outlet − Heat flow inlet (29) In the case of the power generated by the gas turbine generator, W turbine , it was found from the following equation: W = Heat flow inlet − Heat flow outlet (30) The isentropic (ideal) efficiency of the compressor (η c ) was determined from the following equation:…”

“…On the other hand, the power sector emitted 14.6 gigatons of CO 2 in 2022, the highest value compared to other economic sectors [28]. One method of reducing CO 2 emissions in the power sector is to replace fossil fuels with hydrogen, biofuels, ammonia, and other alternative fuels [29][30][31][32]. Simultaneously, incorporating hydrogen into a gas turbine will contribute to bolstering electrical grid stability amidst the growing integration of renewable energy and the shift towards sustainable, carbon-neutral power generation [33][34][35].…”

Decarbonizing the current steel and power sectors through the development of the hydrogen direct-reduction iron ore–electric arc furnace route and the 100% hydrogen-fired gas turbine cycle is crucial. The current study focuses on three clusters of research works. The first cluster covers the investigation of the mass and energy balance of the route and the subsequent application of these values in experiments to optimize the reduction yield of iron ore. In the second cluster, the existing gas turbine unit was selected for the complete replacement of natural gas with hydrogen and for finding the most optimal mass and energy balance in the cycle through an Aspen HYSYS model. In addition, the chemical kinetics in the hydrogen combustion process were simulated using Ansys Chemkin Pro to research the emissions. In the last cluster, a comparative economic analysis was conducted to identify the levelized cost of production of the route and the levelized cost of electricity of the cycle. The findings in the economic analysis provided good insight into the details of the capital and operational expenditures of each industrial sector in understanding the impact of each kg of hydrogen consumed in the plants. These findings provide a good basis for future research on reducing the cost of hydrogen-based steel and power sectors. Moreover, the outcomes of this study can also assist ongoing, large-scale hydrogen and ammonia projects in Uzbekistan in terms of designing novel hydrogen-based industries with cost-effective solutions.

“…According to the International Energy Agency (IEA), about 22% of global CO 2 emissions were derived from natural gas combustion in 2021 [2], and the same levels were maintained in 2022 [11]. A widely studied way to offer the same ancillary services of conventional gas turbines while avoiding CO 2 emissions is represented by substituting natural gas with hydrogen [12]. A successful example of a gas turbine running on blends of up to 100% hydrogen with low Nox was presented by Banihabib et al [10], and the International Energy Agency reports that gas turbines able to run on hydrogen-rich gases or even pure hydrogen are already commercially available [13].…”

The integration of an increasing share of Renewable Energy Sources (RES) requires the availability of suitable energy storage systems to improve the grid flexibility and Compressed Air Energy Storage (CAES) systems could be a promising option. In this study, a CO2-free Diabatic CAES system is proposed and analyzed. The plant configuration is derived from a down-scaled version of the McIntosh Diabatic CAES plant, where the natural gas is replaced with green hydrogen, produced on site by a Proton Exchange Membrane electrolyzer powered by a photovoltaic power plant. In this study, the components of the hydrogen production system are sized to maximize the self-consumption share of PV energy generation and the effect of the design parameters on the H2-CAES plant performance are analyzed on a yearly basis. Moreover, a comparison between the use of natural gas and hydrogen in terms of energy consumption and CO2 emissions is discussed. The results show that the proposed hydrogen fueled CAES can effectively match the generation profile and the yearly production of the natural gas fueled plant by using all the PV energy production, while producing zero CO2 emissions.

“…Relevant research results have indicated that the addition of hydrogen to natural gas can serve to enhance the combustion rate while also extending the stable lean flammability limit of natural gas [8]. However, the achievement of high blending ratios of hydrogen in the fuel mixture presents several technical challenges, such as flashback, combustion pressure fluctuations, and nitrogen oxide emissions.…”

In order to reduce carbon emissions, enhance the operational flexibility of gas turbine power plants, and fill the gap in practical engineering transformation of natural gas-hydrogen blended combustion in heavy-duty gas turbines, a hydrogen blending retrofit was conducted on an F-class heavy-duty gas turbine combined heat and power unit. This served to examine the problems of combustion chamber tempering, combustion pulsation, and NOx emission increase caused by direct hydrogen-doped combustion in the combustion chamber. In this paper, the gas turbine body and hydrogen mixing system were reformed respectively. Retrofit schemes were proposed that were suitable for two operating conditions: 5-15% and 15-30% hydrogen blending. Experimental tests were conducted as a means of evaluating the performance of the retrofitted gas turbine and its compatibility with the boiler and steam turbine. The results of the retrofit showed there to be stable combustion, and there was no significant increase in average burner temperatures or occurrence of flashback. The gas turbine power output mostly remained unchanged and NOx emissions met the regulatory standards. The waste heat boiler flue gas temperature was controlled within the range of 84.9-88.2 ℃, meaning that the safe operation of the steam turbine was not affected. The hydrogen blending rate was 0.2 Vol%/s, which indicates a smooth and precise control of the hydrogen blending process. It was estimated that the annual reduction in CO2 emissions would be 11,000 tons and 28,400 tons following respective hydrogen blending at 15% and 30%. A reliable retrofit scheme for hydrogen blending in gas turbines based on practical engineering transformation is presented in this study, which has significant reference value.
