“…It can be mixed with other fuels such as natural gas and biogas to enrich its application in various power generation systems. For a gas turbine using mixture fuel of hydrogen and natural gas, its operation CO2 emissions will be reduced [5,6]. Using hydrogen and natural gas mix fuel in integrated energy systems is an important trend towards achieving carbon neutrality.…”

Study on Hydrogen Production From Solar Biomass Based on Fe-Ce Catalyst

“…At present, the utilization of biomass includes the following aspects: crop straw and firewood are directly used as fuel, methane is produced by anaerobic fermentation of biomass, methanol fuel and ethanol fuel can be produced by biomass, biochar, fuel gas and bio oil can be produced by pyrolysis, and energy plants can be cultivated by advanced biotechnology. However, there are few studies on the combination of solar energy and biomass energy to produce hydrogen [1].…”

Performance and emission analysis of hydrogen and natural gas cofiring in combined cycle gas turbine power generation

“…A novel GT architecture composed of biofuel, solar cells, an electrolyzer, and a post-firing hydrogen chamber was studied by Cen et al Its performance was compared to that of a biomass-based combined cycle without hydrogen post-firing. In addition to improving capacity, the adoption of a post-firing hydrogen system reduces carbon dioxide emissions by 22.7% under ideal circumstances [19]. Several characteristics, such as plant load, ambient air temperature, ambient air pressure, ambient relative humidity, cooling water temperature, frequency, power factor and generator voltage, process energy extraction, fuel type and quality [20] and fuel pressure [19], typically influence off-design performance of gas turbines.…”
