“…Incorporation of hydrogen in methane fuel blends reduces the methane volume and increases the quantity of carbon-dioxide along with reduction in HC mass in fuel blends. The enhancement of chemical kinetic reaction is mainly due to high reaction rate of hydrogen as compared to methane (Rajpara et al , 2018). The chemical reaction occurs due to addition of hydrogen is represented as follows …”

“…The higher proportion of hydrogen addition increases the formation of hydroxide radicals and further converts carbon monoxide in to carbon dioxide through reaction process represented in equation ( 1). The carbon fraction can be decreased by adding hydrogen for CH 4 for the same content of volumetric fuel resulting in decreased emissions of carbon monoxide and carbon dioxide (Rajpara et al, 2018). In general, nitrous oxide emission mainly occurs due to reaction between oxygen and nitrogen at an higher temperature.…”

Purpose The rise in demand and high utilization of fuel causes severe environmental threat for the nations on the globe. Rapid burning potential of hydrogen produces enormous amount of thrust, and it is mainly owing to wide flame range and less onset of ignition. Design/methodology/approach The significant contribution of hydrogen as fuel has been explored by several researchers around the globe recently to use in aviation sector owing to its eco-friendly nature. Hydrogen is a safe and clean fuel, and it can be generated from several sources. The effects of addition on hydrogen on gas turbine on combustion characteristics and emission concentration level on atmosphere have been reviewed in this paper. Findings Incorporation of hydrogen is effective reducing nitrous oxide emission, high calorific value and flame less combustion. Addition of hydrogen to higher proportions enhances the combustion performance, minimizing the setbacks of conventional fuel and meets the specified standards on emission. Originality/value From the literature review, the comparative study on hydrogen with other fuel is explained. This paper concludes that addition of hydrogen in fuel enhances the performance of combustion on gas turbine engine along with significant reduction in emission levels.

“…Small percentages of hydrogen improve global efficiency in some combustion processes, while large amounts may change the flame typology, decreasing the combustion quality [25,26]. This also implies an increase in pollutant emissions despite the numerous studies that stated that GHG emissions are reduced when hydrogen-methane mixtures are used [27]. Usually, the studied percentages of hydrogen content are between 0 and 50% [28].…”

Experimental Study of Biogas–Hydrogen Mixtures Combustion in Conventional Natural Gas Systems

et al. 2021

Biogas is a renewable gas with low heat energy, which makes it extremely difficult to use as fuel in conventional natural gas equipment. Nonetheless, the use of hydrogen as a biogas additive has proven to have a beneficial effect on flame stability and combustion behavior. This study evaluates the biogas–hydrogen combustion in a conventional natural gas burner able to work up to 100 kW. Tests were performed for three different compositions of biogas: BG70 (30% CO2), BG60 (40% CO2), and BG50 (50% CO2). To achieve better flame stability, each biogas was enriched with hydrogen from 5% to 25%. The difficulty of burning biogas in conventional systems was proven, as the burner does not ignite when the biogas composition contains more than 40% of CO2. The best improvements were obtained at 5% hydrogen composition since the exhaust gas temperature and, thus, the enthalpy, rises by 80% for BG70 and 65% for BG60. The stability map reveals that pure biogas combustion is unstable in BG70 and BG60; when the CO2 content is 50%, ignition is inhibited. The properties change slightly when the hydrogen concentrations are more than 20% in the fuel gas and do not necessarily improve.

“…It is currently a good idea to promote improved combustion methods for hydrocarbon fuels mixed with hydrogen gas in gas turbine applications [11]. Rajpara et al [12] investigated the emission properties of a CH4 / H2 mixture in a combustion chamber and observed that the addition of hydrogen increases the flame temperature, reduces the flame dimensions and thus CO. Other studies [13] focused on the thermoeconomic evaluation of a new integrated CHP system integrating solar energy-based technologies, a biogas-steam reformer with methanol, and hydrogen generation. Ouchikh et al [14] investigated of the influence of hydrogen enrichment in natural gas on the combustion parameters of a dual-fuel diesel engine.…”

This study deals with implementing an analytical model to simulate the energy performance associated with a Micro Gas Turbine when H2NG (Hydrogen Enriched Natural Gas) blends are used as fuel. The experimental campaign validated the simulation results at the actual operating conditions of the Micro Gas Turbine. The experimental campaign for model validation has been carried out over the spring and summer periods. Additionally, the MGT performance has been detected when fuelled H2NG with hydrogen fraction ranges between 0% vol. to 10% vol., with a 2% vol. Step., according to the main findings, the fuel consumption is reduced significantly. Also, heat recovery and electrical reliability improve slightly even though environmental factors influence the system. A numerical model was developed with MATLAB-Simulink to model the operation of the MGT. Thus, the relative standard errors affecting the main output parameters have been determined.
