Hydrogen/Ammonia Combustion Power Generation Realizing Carbon Neutrality and Expectations for Thermal Spray Technology

Abstract

In order to realize a carbon neutral society, substitutional fossil fuels such as hydrogen and ammonia are considered for next-generation gas turbines for power generation. This review describes a brief summary of research-related activities regarding a carbon neutrality and the current status of hydrogen combustion gas turbines especially with a pure oxygen-hydrogen combustion type and ammonia combustion gas turbines. Based on the combustion environment with such alternative fuels, the needs for materials and coating development are discussed.
