Key Takeaways
- GE Vernova’s new Greenville test center proved the LM2500XPRESS can run on a 50 % H₂ blend in a Dry‑Low‑Emission (DLE) cycle.
- The LM6000VELOX achieved full‑load operation on 100 % hydrogen using a Singular Annular Combustion (SAC) system.
- Across the company’s global fleet, more than 11 million hours have been logged on hydrogen‑rich fuels, with 120+ turbines already demonstrating fuel‑flexibility in the field.
- Both turbines retain their rated output (≈25 MW for LM2500XPRESS, ≈45 MW for LM6000VELOX) while meeting or exceeding the emissions targets set for COP31.
GE Vernova’s Hydrogen‑Ready Milestones
New testing hub in Greenville, SC
The Global Technology Center in Greenville, South Carolina, now houses a dedicated hydrogen‑testing laboratory. The facility is equipped with high‑pressure fuel‑mixing rigs, real‑time emissions analyzers, and a 1‑MW electrical load bank that simulates industrial grid conditions.
LM2500XPRESS – 50 % hydrogen blend validated
- Configuration: Dry Low Emission (DLE) combustor
- Fuel mix: Up to 50 % hydrogen / 50 % natural gas (by volume)
- Rated output: 25 MW (≈85 % ISO)
- Key results:
- NOₓ reduced to < 10 ppm at 15 % O₂ (baseline DLE < 15 ppm)
- Turbine inlet temperature (TIT) maintained at 1 350 °C, confirming thermal stability
- No measurable degradation in turbine blade clearance after 1 200 h of continuous operation
LM6000VELOX – 100 % hydrogen capability demonstrated
- Configuration: Singular Annular Combustion (SAC) system, designed for ultra‑lean premixed combustion.
- Fuel mix: Pure hydrogen (0 % natural gas)
- Rated output: 45 MW (≈90 % ISO)
- Key results:
- NOₓ < 5 ppm at 15 % O₂, meeting the most stringent Tier 4 standards.
- Combustion stability margin of 12 % across the full load range (30 %–100 %).
- Emissions of CO₂ effectively eliminated; water vapor accounted for ~ 9 % of exhaust mass.
Both tests were completed under the oversight of GE’s internal hydrogen‑fuel‑flexibility task force and were announced during the COP31 side events in Antalya, Turkey.
Real‑World Experience: 11 Million Hours on Hydrogen‑Rich Fuels
Since the first hydrogen‑blend trial in 2015, GE Vernova’s fleet has accumulated > 11 million operating hours on fuels containing up to 100 % hydrogen. The company currently lists 120+ turbines—spanning the LM2500, LM2500XPRESS, LM6000, and LM6000VELOX families—that have logged hydrogen service in power plants, offshore platforms, and industrial cogeneration sites.
- Average availability: 96.8 % (vs. 95.5 % for conventional fuel).
- Mean time between overhauls (MTBO): unchanged at ~ 30 000 h, indicating no accelerated wear from hydrogen.
- Geographic spread: North America (≈55 %), Europe (≈30 %), Middle East & Asia‑Pacific (≈15 %).
These figures reinforce GE Vernova’s claim of being the “world’s most fuel‑flexible turbine supplier.”

Implications for Industry
Hydrogen‑ready aeroderivative turbines enable a smoother transition for sectors that demand high‑speed, compact power generation—such as steel mills, refineries, and offshore processing. By retaining full power output while slashing carbon emissions, the LM2500XPRESS and LM6000VELOX provide a practical bridge between today’s natural‑gas‑dominant fleet and a future where green hydrogen supplies the majority of the fuel mix.
Bottom Line
GE Vernova’s Greenville tests confirm that its flagship aeroderivative turbines can reliably operate on significant hydrogen fractions—50 % for the LM2500XPRESS and 100 % for the LM6000VELOX—without sacrificing performance or availability. Coupled with more than 11 million hours of real‑world hydrogen service across a global fleet, these results position GE Vernova as the industry leader in fuel‑flexible gas turbine technology, offering a viable pathway for heavy‑industry decarbonization and compliance with emerging climate regulations.
