H-25 Series gas turbine
MHI: 100% direct use of ammonia: To develop 40,000 kW class gas turbine
March 1, 2021
Mitsubishi Heavy Industries:
◆ Contributing to the construction of a fuel ammonia supply chain by establishing 100% ammonia direct combustion technology
◆ It is possible to propose small and medium-sized power plants and decarbonized menus in industrial fields and remote islands.
Mitsubishi Power:
Momentum for decarbonization is increasing.
We have started “development of a 40,000 kW class gas turbine system that directly uses 100% of ammonia (NH3) as fuel for gas turbine power generation”.
Ammonia-fired 40,000 kW class gas turbine:
The ammonia-only combustion method does not generate CO2 when using fuel.
Achieve carbon-free power generation:
In the future, we aim to put it into practical use after 2025 through combustion tests.
“Practical application of ammonia direct combustion gas turbine at this output scale” is unprecedented in the world.
Dealing with NOx is an issue:
In the direct combustion of ammonia, the nitrogen in the fuel is oxidized by the combustion.
Dealing with the generated nitrogen oxides (NOx) is the most important issue.
Utilization of H-25 type gas turbine (40,000 kW class) technology
Our H-25 type gas turbine (40,000 kW class) has abundant operation results in the world.
“Development of NOx emission reduction and combustor utilizing this technology”
“Gas turbine system combined with denitration equipment”
We aim to put it to practical use.

Mitsubishi Power, Ltd. | Mitsubishi Power Commences Development of World's First Ammonia-fired 40MW Class Gas Turbine System
— Targets to Expand Lineup of Carbon-free Power Generation Options, with Commercialization around 2025 —
2021-03-01
･ Utilizing technology that enables 100% direct combustion of ammonia will contribute to formation of ammonia fuel supply chain
･ Commercialization will also support decarbonization systems for small to medium-scale power plants in industrial applications, on remote islands, etc.
YOKOHAMA, JAPAN (March 1, 2021) – Mitsubishi Power, a subsidiary of Mitsubishi Heavy Industries (MHI) Group,
has commenced development of a 40-megawatt (MW) class gas turbine that is fueled by 100% ammonia (NH3).
The project was started in response to the increasing global focus on decarbonization.
As firing of ammonia produces no carbon dioxide (CO2), carbon-free power generation is achieved.
Going forward, after combustion and other testing, Mitsubishi Power is targeting commercialization in or around 2025.
When achieved, it will mark the world’s first commercialized gas turbine to make exclusive use of ammonia as fuel in a system of this scale,
and will aid in the promotion of decarbonization of small to medium-scale power stations for industrial applications, on remote islands, etc.
Developing a method for directly combusting ammonia will further expand Mitsubishi Power’s lineup of carbon-free power generation systems.
A challenge needing to be addressed with direct combustion of ammonia
is the production of nitrogen oxide (NOx) caused by oxidation resulting from the combustion of the nitrogen component of the fuel.
H-25 Series gas turbines (40MW class)
Mitsubishi Power is aiming to resolve this issue through commercialization of a gas turbine system that combines selective catalytic reduction (SCR) with a newly developed combustor that reduces NOx emissions,
for installation in the Company’s H-25 Series gas turbines (output: 40MW class), which has a rich operational track record spanning the globe.
