Mitsubishi Power- a subsidiary of Mitsubishi Heavy Industries (MHI) Group- has initiated the development of a 40-megawatt (MW) class gas turbine to achieve carbon-free power generation.
The equipment is fueled by 100 percent ammonia (NH3) and firing of ammonia produces zero carbon dioxide (CO2).The project was started in response to the increasing global focus on decarbonisation, said a press release.
Mitsubishi Power is looking forward to commercialising the equipment in or around 2025 after combustion and other testing.
The gas turbine aims to make exclusive use of ammonia as fuel in a system of this scale, and it will aid in the promotion of decarbonization of small to medium-scale power stations for industrial applications, on remote islands, and others.
In addition, Mitsubishi Power is working to reduce environmental impact through the development of high-efficiency power generation technologies.
To date, the company has pursued technological developments enabling a transition from natural gas fuel used in gas turbine combined cycle (GTCC) systems, which currently emit the lowest amount of CO2 among thermal power generation systems, to hydrogen, which emits no CO2.
In tandem with pursuing active use of ammonia, the company has also been developing a system in which the waste heat from a gas turbine reconverts ammonia into hydrogen and nitrogen for use in hydrogen gas turbines.The development of a method for directly combusting ammonia will further expand Mitsubishi Power’s lineup of carbon-free power generation systems.
Mitsubishi Power will work to advance the energy transition as a member of MHI Group.
Through prioritising its resources into expanding its gas turbine power generation and other efficient, environmentally friendly generation technologies, the company will contribute to the stable supply of power, indispensable to global economic development, and the protection of the environment through the promotion decarbonization.
