Developing advanced turbine technologies in pursuit of power generation with higher efficiency, lower costs and lower emissions

The NETL Advanced Turbines Program manages a research, development, and demonstration (RD&D) portfolio designed to enable a carbon-free electricity sector and promote environmental justice by developing revolutionary, near-zero-emission advanced turbines technologies. In response to the nation’s increasing power supply challenges, NETL is researching next-generation turbine technology with the goal of producing reliable, affordable, diverse and environmentally friendly energy supplies. NETL is also committed to enabling the use of hydrogen in gas turbines to facilitate a future carbon-free electric power industry. Program and project emphasis is on understanding the underlying factors affecting combustion, aerodynamics/heat transfer, and materials for advanced turbines and turbine-based power cycles.
