Hydrogen-fueled gas turbines in future energy system.

Recently, hydrogen application has been a new and promising technology in gas turbines, paving the way towards a cleaner and more sustainable energy future. However, challenges and considerations accompany this technology due to hydrogen's combustion characteristics compared to traditional fossil fuels. This review presents a comprehensive analysis of recent advancements in hydrogen-fueled gas turbines, focusing on their impacts on gas turbines, economic evaluation, and the development of commercial hydrogen gas turbines. Our analysis demonstrated that the unique combustion characteristics of hydrogen will influence combustion stability, flame dynamics, and the overall combustion process in gas turbines. The challenges associated with commercial hydrogen gas turbines encompass the high cost of hydrogen production, effective and efficient hydrogen combustion, material compatibility, and the imperative need for supportive regulatory measures. • Hydrogen influences combustion stability and the overall performance in gas turbines. • Economic viability of a hydrogen gas turbine depends on various factors. • Test results demonstrate the feasibility of commercial hydrogen gas turbines. • Cost of hydrogen gas turbines is expected to decrease for economies of scale.
