Mitsubishi to start technical studies at Indonesian power plants

Mitsubishi Heavy Industries (MHI), and Pt. PLN Nusantara Power, a subsidiary of Indonesia’s state electricity provider PT. PLN (Persero), have signed a Memorandum of Understanding (MOU) to initiate three technical studies related to co-utilization of less carbon-intensive fuels in power plants owned and operated by Nusantara Power.

The three studies will be carried out jointly by Nusantara Power and MHI with the support of Mitsubishi Power, MHI’s brand of energy solutions.

This MOU follows a similar agreement concluded with Indonesia Power in November 2022, and will further contribute to advancing solutions to accelerate the decarbonization of energy systems in Indonesia.

A pair of studies to be carried out at the Muara Karang power station, located in Java about 10 kilometers from the capital Jakarta, will examine the potential of introducing hydrogen co-firing for an M701F series turbine currently in operation, and the co-combustion of ammonia in a gas boiler.

MHI has supplied much of the plant’s major equipment, including various gas turbines, boilers and steam turbines.

Mitsubishi aims to electrify all its vehicles by 2035

A study at the Paiton coal-fired power plant, also located in Java and owned by Nusantara Power, will assess the technical aspects of the feasibility of biomass co-firing.

The signing of this MOU was announced at the Asia Zero Emissions Community (AZEC) Public-Private Investment Forum, held in Tokyo by the Japanese Ministry of Economy, Trade and Industry (METI). During this event, several initiatives for decarbonization were proposed in markets throughout Asia, supported by the technology and experience of Japanese companies.

This MOU builds on the strong existing cooperation between MHI and PLN in Indonesia. Since 1971, MHI’s power solutions brand, Mitsubishi Power, has been supporting PLN and its organizations with solutions for power plants across the country, including Muara Karang, Gresik, Tanjung Priok, Suralaya and Grati power plants.

In March 2022, MHI and PLN together with Institut Teknologi Bandung prepared a joint proposal on the adoption of biomass co-firing in Indonesian thermal power plants and presented their conclusions to the national government.

Through this MOU and other ongoing initiatives, MHI, with the support of Mitsubishi Power, will work to help Indonesia achieve its goal of net zero emissions by 2060.
