PT Pupuk Kujang, a subsidiay of State-owned fertilizer producer holding company PT Pupuk Indonesia, is conducting a trial production of green ammonia projected to replace coal in the power generation industry.
Robert Sarjaka, Director of Operations and Production of Pupuk Kujang, said that the production of green ammonia is part of the company’s efforts to contribute to realizing the energy transition in Indonesia, namely making Pupuk Kujang the first company to produce green ammonia in the country.
“So this is a milestone in the energy sector,” Sarjaka said on Tuesday, February 4, 2025.
Pupuk Kujang, an old player in the ammonia industry, currently has complete facilities in producing ammonia, which is also used to produce green ammonia.
“Green ammonia is the cleanest ammonia, it does not produce carbon directly when burned. The raw material is green hydrogen, without fossil fuels,” Sarjaka cited.
In the process of producing green ammonia. Pupuk Kujang collaborates with PLN Indonesia Power (PLN IP), a subholding of State power utility PT PLN, which supplies green hydrogen, as one of the raw materials in the process of making green ammonia.
In the first trial phase, Pupuk Kujang will process 1 ton of green hydrogen into 5 tons of green ammonia.
“We will fulfill the needs of PLN IP which requires 50 tons of green ammonia to power the turbine at the Labuan Coal-fired power plant (PLTU),” he said.
Iswahyudi Mertosono, Vice President for Development at PT Pupuk Kujang, said that the injection of green hydrogen in the existing ammonia plant to produce hybrid ammonia is the first process in the world.
“Designing this process requires piping modifications and risk and technical evaluations that are not simple,” Iswahyudi said.
