MHI, Indonesia Power to decarbonise power plants in Indonesia

Mitsubishi Heavy Industries (MHI) and Indonesia Power have concluded a memorandum of understanding (MoU) to start three feasibility studies on co-firing less carbon-intensive fuels at the latter’s power plants in Indonesia, MHI said on November 2.

The three studies will be conducted jointly by Indonesia Power, a unit of state-owned utility PLN, and MHI with support from Mitsubishi Power.

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 the existing boiler, MHI said.

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