Indonesian Perusahaan Listrik Negara’s (PLN) units have agreed to conduct a joint study on the use of green ammonia at two coal-based thermal power plants (TPPs) in Java island, to reduce carbon emissions.
Under the agreement, PLN subsidiaries – PT PLN Enjiniring and PT Indo Raya Tenaga – will study the feasibility of co-firing 60 per cent of green ammonia at Jawa 9 and Jawa 10 coal-fired TPPs with a total capacity of 2,000 MW (2×1,000). The plants are expected to start operations in 2025 and 2026 respectively. The ammonia co-firing will be complemented with selective catalytic reduction (SCR) systems to neutralise carbon. Notably, PLN’s decarbonisation plan includes efforts to accelerate the shutdown of coal based TPPs, targeting early retirement of roughly 3.7 GW coal power capacity before 2030.
