MHI and Indonesia Power to investigate H2 Co-firing

8 November 2022

Mitsubishi Heavy Industries and PLN Indonesia Power, a sub-holding of Indonesia's state-owned electricity provider PLN, have concluded a Memorandum of Understanding to commence three feasibility studies on co-firing less carbon intensive fuels at power plants owned and operated by Indonesia Power. The three studies will be conducted jointly by Indonesia Power and MHI with support from its power solutions brand, Mitsubishi Power, and are intended to aid in the advancement of solutions to accelerate the decarbonisation of energy systems in Indonesia.

The first study will examine the technical and economic feasibility of co-firing up to 100% biomass at the Suralaya coal-fired power plant (CFPP). The study will consider various aspects of the biomass supply chain, including handling, storage, transport and boiler modification. The second study, which will also use Suralaya CFPP as the reference plant, will investigate co-firing of ammonia produced by existing ammonia plants in Indonesia. A particular area of focus will be the potential to establish a blue ammonia supply chain with production and transportation from the ammonia plant and ammonia co-firing technology to apply in existing boiler.

The third study will evaluate the technical and economic feasibility of hydrogen co-firing in an M701F gas turbine at the Tanjung Priok gas turbine combined cycle (GTCC) facility. MHI completed construction of the plant's Unit 2 GTCC system in 2019 as part of PLN's plans to build an 880 MW plant under the Jawa-2 Project.

This new MoU builds on strong existing co-operation between MHI and PLN in Indonesia. Since 1971, MHI's power solutions brand Mitsubishi Power has been providing PLN and Indonesia Power with solutions for power plants across the country, including the Tanjung Priok, Suralaya and Grati power plants. More recently, in March this year, MHI and PLN, together with Institut Teknologi Bandung, prepared a joint proposal on biomass co-firing adoption at Indonesia's thermal power plants and presented their findings to the national government.
