Pupuk plans $500m Batam ammonia hub

The proposed hub would combine ammonia production, storage, distribution and trading for domestic and international markets. It would also supply ammonia as a potential marine fuel, positioning Batam to compete with neighbouring Singapore.

Pupuk Indonesia president director Rahmad Pribadi and his team met BP Batam head Amsakar Achmad and other officials on 2 November. In a release issued on 4 November, the company said BP Batam would support licensing and land allocation once an agreement was reached. A joint team would be established when the project reached the ready-to-invest stage.

“This is not about resource nationalism—it is about resource industrialization,” Rahmad said. “We remain open to collaboration. What matters is that added value is created and retained in Indonesia.”

Potential gas supply routes

Potential feedstock sources include the Grissik gas processing and transmission hub in South Sumatra and offshore producing areas in the Natuna Sea. These are separate supply areas served by different pipeline systems.

Grissik is part of MedcoEnergi’s Corridor operations and is connected to the Grissik–Batam–Singapore transmission system, operated by PT Transportasi Gas Indonesia. Indonesia’s Directorate General of Oil and Gas identifies a 468 km pipeline transporting gas, including supplies from Medco Grissik, to Singapore through the Batam area.

Natuna’s offshore producers supply the West Natuna Transportation System. Medco’s May 2025 gas swap announcement identifies South Natuna Sea Block B, Natuna Sea Block A and Kakap as members of the West Natuna supply group. Pupuk Indonesia has not identified which Natuna fields or blocks could supply the ammonia project.

The company’s release links the proposal to an Indonesia–Singapore gas supply contract that it says expires in 2028. It does not identify the contract, its counterparties or the volumes that could become available. No project-specific feedstock supply agreement or delivery arrangement has been announced.

Land and gas remain prerequisites

Pupuk Indonesia and BP Batam are evaluating several locations. Site selection would need to take account of the authority’s long-term development plans, according to Indonesian news outlet Beritasatu.

“What we need is certainty over the land, and then the feedstock, namely natural gas,” Rahmad told journalists after the meeting, in comments translated from Indonesian. He said construction could proceed once those requirements were resolved and estimated a construction period of approximately three years. No fixed construction start or commissioning date has been announced.

Investment could cover several plants

The distributed release puts the proposed investment at up to $500 million. Indonesian reporting provides a more specific description: Bisnis.com quoted Rahmad putting the cost of one ammonia plant at approximately $500 million, while Beritasatu reported that several plants could eventually be developed, depending on requirements. No total investment figure has been announced for a multi-plant development.

Bisnis.com also reported that Pupuk Indonesia intended to finance the plant from internal cash resources. Rahmad said construction could employ up to 8,000 workers. These funding and employment details were reported separately and were not included in the distributed release.

Pupuk Indonesia cited existing group ammonia production capacity of approximately 7.1 Mt. That figure does not represent the proposed capacity of the Batam development.

Capacity and technology undisclosed

The announcements reviewed do not specify the Batam plant’s annual production capacity, potential technology provider, engineering contractor or offtake arrangements. A selected site, agreed gas price and final investment decision have also not been announced.

Although the proposal includes ammonia’s potential use as a marine fuel, the company has not specified whether production would be conventional, blue or green ammonia. The announcement does not identify a carbon capture system or a renewable hydrogen supply for the proposed facility.
