Jereh Oilfield Services (002353 CH) Hold: We are not as positive on repurposed jet engines

F6-80C2 engines) has successfully

produced aero-derivative turbines for power generation using retired jet engines as the core

turbine (EEPower, Nov 2025). All other aero-derivative turbines in the market are new units,

including those from GE, Mitsubishi and Boom Supersonic; they are described as aero-derivative

because they use flight-engine technology and design, not because they are refurbished retired

flight engines. For example, Mitsubishi acquired Pratt & Whitney Power Systems (now Mitsubishi

Power Aero) in 2013, which uses proven, high-performance jet engine technology (such as the

FT8 and FT4000) to produce new, industrial-grade gas turbines for power generation. Key

issues with repurposing retired flight engines include:

◆ Unlike a factory‑new OEM unit with a clear delivery pedigree, repurposed cores require

additional operator diligence around prior life, overhaul quality, record

completeness, and residual risk; these issues can become a security-of-supply concern

when uptime depends on a multi-unit fleet and a narrow spares ecosystem.

◆ CFM56 engines are optimised for flight cycles (frequent starts and stops with defined

operating profiles). Data centres, by contrast, often require near-continuous operation,

sometimes exceeding 8,000 hours per year (source: Time Energy, 10 Jan 2026).

◆ Environmental Concerns: Noise and emissions can create local permitting challenges.

Retrofitting emissions control systems is possible, but adds cost, complexity and time, and

can become a critical-path risk for project delivery. Aircraft engines were not designed to

meet modern stationary emissions standards. When deployed at data centres, CFM56-
