DECARBONIZING POWER GENERATION
Hydrogen fueled gas turbines
While the effort to reduce carbon emissions from traditional power generation assets is driving an increase in renewable power production from renewables, hydrogen-ready gas turbines could also play a role. See how we’re leading the charge.
Can GE’s gas turbines run on hydrogen fuel?
YesOur turbines have nearly 30 years of experience operating on a variety of fuels that contain hydrogen, totaling over 4 million operating hours as hydrogen-fueled turbines using concentrations ranging from 5% to 95% (by volume). This includes synthesis gas (syngas), a variety of steel mill gases (i.e. coke oven gas and blast furnace gas), and refinery off-gases. This experience has helped GE become one of the world leaders in the application of fuels containing hydrogen in gas turbines.
The use of hydrogen as a gas turbine fuel has been demonstrated commercially, but there are differences between natural gas and hydrogen that must be taken into account to properly and safely use hydrogen in a gas turbine. In addition to differences in the combustion properties of these fuels, the impact to all gas turbine systems as well as the overall balance of plant, must be considered. In a power plant with one or more hydrogen-fueled turbines, changes may be needed to the fuel accessories, bottoming cycle components, and plant safety systems. GE’s broad field experience enables our engineers to understand the impact of using hydrogen as a gas turbine fuel.
As gas turbines are inherently fuel-flexible, they can be configured to operate on green hydrogen or similar fuels as a new unit, or be upgraded even after extended service on traditional fuels, i.e. natural gas. The scope of the required modifications to configure a gas turbine to operate on hydrogen depends on the initial configuration of the gas turbine and the overall balance of plant, as well as the desired hydrogen concentration in the fuel.
