Dongfang Electric Group Releases First 15-Megawatt Pure Hydrogen Gas Turbine

On September 18, Dongfang Turbine, a subsidiary of Dongfang Electric Corporation, officially launched its first self-developed 15-megawatt pure hydrogen gas turbine (G15H). The successful development of this product fills the technological gap in China's large-power pure hydrogen gas turbine sector, marking China's entry into the global first tier in the field of zero-carbon power equipment.

Technological Breakthrough and R&D Journey:

Technological Leap: G15H is not a simple fuel replacement but represents a "reconstructive innovation" of the combustion system. The R&D team employed micro-premixed combustion technology based on cross-flow jets, successfully overcoming three global technical challenges in pure hydrogen combustion: high-temperature nitrogen control, flashback prevention, and oscillation suppression.

Empirical Validation: The product underwent multiple rounds of extreme testing. During the "full-temperature, full-pressure real-condition test" in 2024, it achieved no flashback or thermoacoustic oscillations throughout the process, from ignition to full-load operation, with stability comparable to mature natural gas units, proving a critical leap from "technologically feasible" to "industrially usable."

Application Scenarios and System Value:

Diverse Applications:  With a power of 15 megawatts, it can be flexibly applied in distributed energy stations and industrial park combined heat and power systems, providing zero-carbon power and heat sources.

System Hub: In the long term, G15H can integrate with hydrogen storage systems to establish a "power-hydrogen-power" clean energy cycle, converting surplus renewable electricity into hydrogen for storage and generating stable grid power when needed, serving as a core balancer to address the volatility of new energy and support the stability of new-type power systems.

Strategic Industry Significance:
The debut of G15H demonstrates that hydrogen energy can transition from the laboratory to becoming a "green heart" driving industrial operations. It not only provides a reliable zero-carbon power solution for the industrial sector but also highlights China's mastery of core technologies in high-end hydrogen energy equipment, contributing an exemplary "China solution" to global zero-carbon transformation.
