Power generation from ammonia combustion: Challenges toward carbon neutral society
Akihiro Hayakawa
Associate Professor
Institute of Fluid Science, Tohoku University, Japan
Abstract:
Ammonia is a potential candidate of fuel towards carbon neutral society. Infrastructures for ammonia production, distribution and storage are available. However, there are challenges to use ammonia as fuel from the standpoint of combustion science for power generation by a gas turbine, since the characteristics of ammonia flame is remarkably different from those of conventional hydrocarbons, such as methane.
In this talk, a background of ammonia utilization will be introduced. Fundamental flame characteristics of ammonia, such as laminar burning velocity and product gas characteristics, are explained. Then, a new combustion concept is shown to achieve simultaneous reductions of NO and unburnt ammonia from ammonia flame.
Bio:
Since receiving his Ph.D. from Kyushu University in 2013, Dr. Akihiro Hayakawa has been engaged in research of application of NH3 as a near zero emission fuel system. Currently, he serves as an associate professor at the Institute of Fluid Science, Tohoku University. His research interests are ammonia combustion, high pressure combustion, turbulent combustion, and laser diagnostics. Dr. Hayakawa was a visiting researcher at the University of Cambridge in 2015. He was selected to 2022 Energy and Fuels Rising Stars from ACS (American Chemical Society) Publications. |
