Emissions reduction benefits from hydrogen addition to midsize gas turbine feedstocks

Fuel flexibility, stability and emissions in premixed hydrogen-rich gas turbine combustion: Technology, fundamentals, and numerical simulations

“…This can be seen as a method for reducing NO x emissions and compete with other technique, namely dry low NO x and SCR (selective catalytic reduction). TerMaatha et al [130] conducted an economic analysis comparing these methods. On average the presence of 15% hydrogen addition produced 3 ppm of NO x emissions [130].…”

“…TerMaatha et al [130] conducted an economic analysis comparing these methods. On average the presence of 15% hydrogen addition produced 3 ppm of NO x emissions [130]. Operating mid-size gas turbines with this level of hydrogen in the fuel was shown to be cost competitive with the other methods of NO x reduction.…”

Lean Hydrogen Combustion

“…Purely economic considerations also favor limiting the amount of hydrogen to something less than 20-40% in NG for power generation. At these addition levels, the costs are comparable to other NO x control strategies for achieving emission levels of 3 ppm or less (TerMaath et al, 2006). The use of "designer fuels", formed by blending hydrogen with a hydrocarbon feedstock to optimize combustor operation, is well suited to power generating gas turbine systems (Boschek et al, 2005;Strakey et al, 2006).…”

Improvement in Hydrogen Production with Plasma Reformer System

“…Spark ignition (SI) and diesel engines, widely used to power various types of vehicles, have been shown to be a major source of air pollution in cities [3]. The addition of hydrogen for combustion helps reduce pollutant emissions [4], and the use of fossil fuels. However, pure hydrogen feeding is relatively difficult for practical applications and can result in safety issues and storage problems.…”
