Technology Description:

General Electric (GE) Gas Power will study high-velocity lifted-flame reheat combustion within the turbine section as a high-risk, high-payoff technology to achieve high-efficiency gas turbine operation with nearly pure hydrogen (H2) fuels. GE is proposing a novel approach to H2 jet injection into the main flow path in the hot gas path section to evaluate the commercial attractiveness of this approach in land-based gas turbines. This concept has never been tried with very high-H2 content fuels (greater than 80% H2 blended with natural gas) at high-velocity forward turbine stage flow conditions. GE’s new technology could break the current, materials-limited upper bound efficiency barrier for gas turbines, create a new GTCC growth trajectory, and enable net GTCC plant efficiencies of 67% or greater on a wide range of fuel compositions while meeting strict emissions standards.

Potential Impact:

The proposed technology is anticipated to provide a step-change improvement in GTCC net plant efficiency and reduce carbon emissions.

Security:

The new technology can strengthen the role for reliable, decarbonized dispatchable power via highly efficient GTCC electric power generation.

Environment:

The proposed technology can potentially move the power generation industry from its reliance on natural gas fossil fuels and onto renewables-based H2 fuel sources while reducing the energy losses due to inefficiencies.

Economy:

This technology aims to position decarbonized power cycles to be economically viable so that modern standards for cost of electricity, grid reliability, and emissions (in addition to CO2, such as NOX) can be first maintained and eventually improved.
