The Korea Institute of Machinery and Materials (KIMM) has created a hydrogen co-firing combustor for gas turbines used in power generation.
The application of KIMM in power plants will be shown by the company. The KIMM team has been trying to create a 30% hydrogen co-fired, ecologically friendly combustor for residential gas turbines in collaboration with 13 business, academic, and research partners. A field trial project involving Doosan Energy and Korea East-West Power Company will start in 2023.
KIMM created a fuel injection method that involved separating the gasoline, staging it, and adjusting the fuel holes. These were used in conjunction with the large duty gas turbine from Doosan Energy. As a result, it was possible to burn fuel that included 30% hydrogen while lowering NOx emissions and combustion instability to levels comparable to those of the original LNG gas turbine.
The KIMM-developed combustor was sent to the German Aerospace Center (DLR) during the development phase, where it successfully completed high-pressure combustion tests.
When gas turbines employ fuel mixed with 30% hydrogen, CO2 emissions can be lowered by 10.4% in comparison to 100% LNG power generation. By increasing the proportion of hydrogen in fuel beyond 50% by 2024, KIMM hopes to reduce CO2 by 21.4%. In addition, the team is focusing its research efforts on developing a carbon-free hydrogen combustion technology by 2030.
