Thailand currently relies on natural gas for approximately 50-60% of its electricity generation, providing baseload power to maintain system stability. Replacing natural gas entirely with renewable energy remains challenging because of limitations in supply reliability and the readiness of the electricity grid.
Key facts
- In 2023, MHI achieved what the source describes as the world’s first demonstration of co-firing a 30% hydrogen blend with natural gas, using five JAC (J-Series Air-Cooled) gas turbines at T-Point 2
- During 2024-2025, MHI subsequently tested combustion using 100% hydrogen in its medium-sized H-25 gas turbine, with a capacity of 40 megawatts, in preparation for commercial deployment
- The company aims to enable its large gas turbines to operate on 100% hydrogen after 2030.
- The demonstration reduced CO₂ emissions by 10%.
- Meanwhile, the Electricity Generating Authority of Thailand (EGAT) has been studying the feasibility of blending 5% hydrogen with natural gas for electricity generation at six of its power plants: North Bangkok, South Bangkok, Wang Noi,
- It is expected to play a role in the country’s electricity system after 2040, reflecting continuing limitations in cost and commercial readiness.
Summary
PR news
Blending hydrogen with natural gas for electricity generation, known as hydrogen co-firing, is therefore emerging as a promising option. The approach involves gradually increasing the hydrogen content and reducing natural gas consumption as technology and costs allow.
