LM2500XPRESS is a trademark of General Electric Company LM6000 Flexible and modular package design <90 days I&C schedule (38% schedule improvement / 4000+ manpower hours reduction) Substantial savings for EPCs (when GTG is critical path) Aero grid stability characteristics Spinning reserve with >20MW/min ramp rate to full load Faster frequency response Ability to ride through frequency and voltage variations Low voltage ride through capability High system inertia Synchronous condensing capability for system support GRID FIRMING (also known as capacity firming) is the addition of other energy resources to balance the intermittency of renewable ones in order to provide a secure and stable power within the desired dispatchable duration. Synchronous condensing complements the influx of renewables Provides reactive power for both high and low grid voltage Absorbs VARS in small increments, correcting lagging/leading power factors Provides power factor/voltage support in urban centers and industrial areas, provides stability and ensures increased power transmission Generates additional revenue in deregulated markets Can provide qualification for spinning reserve requirements or credits Aero experience Several units already running in synchronous condensing mode LM6000 package PC & PF turbines: Clutch skid placed between turbine and generator skids PF+ turbine: Clutch integrated into gearbox skid LM2500 / TM2500 Free spinning power turbine allows any unit to operate as clutchless synchronous condenser Back Decarbonization LOOKING TOWARDS THE FUTURE GE’s experience with H2 leads the gas turbine industry GE has continued development of combustion technology, leading to the DLN 2.6e combustion system GE is ready for a world with low carbon fuels GE gas turbine hydrogen capability GE’s experience with hydrogen and other low btu fuels includes more than 100 turbines in operation and over 8 million hours on these fuels. GE has combustion technologies that are capable of operating on a wide range of hydrogen concentrations up to ~100 (by volume). GE H2 experience list HYDROGEN EXPERIENCE GE’s experience with hydrogen includes more than 100 turbines and over 8 million operating hours Decades of aero experience with hydrogen and similar fuels >25 units…over 2.2 million operating hours GE has 40 years of operating experience with aeros on hydrogen fuels New hydrogen projects with GE gas turbines New York Power Authority (NYPA) - Brentwood Power Station (NY, USA) A NYPA-led, first-of-its-kind demonstration project to test the potential of substituting renewable hydrogen for a portion of the natural gas used to generate power at NYPA's Brentwood Power Station, which consists of a GE LM6000 combustion turbine currently fueled by natural gas. Long Ridge Energy Terminal Hannibal, Ohio Long Ridge summary: Long Ridge Energy Terminal and GE announced a successful first step to transition Long Ridge’s power toward carbon-free hydrogen. Following the start of commercial operation achieved in October 2021, the plant conducted a successful demonstration using a hydrogen-blended fuel in GE’s 7HA.02 HA gas turbine, making Long Ridge the first purpose-built hydrogen-burning power plant in the United States and the first worldwide to blend hydrogen in a GE H-class gas turbine.
