Paiton Energy, an Indonesian power producer, is in talks with Mitsubishi Power to build a 2.6 GW combined-cycle gas turbine (CCGT) plant that can run on hydrogen blends. The company currently operates 2.04 GW of coal capacity in East Java and wants to cut its fleet's carbon intensity by about 34% from the current 913 gCO2/kWh. The project is part of a 2025-2060 roadmap that treats gas as a bridge fuel, with plans for hydrogen and ammonia co-firing by 2030 and a 1 GW carbon capture pilot. Mitsubishi's JAC-series turbines can already handle up to 30% hydrogen, and the company claims high efficiency and reliability. However, questions remain about the source of hydrogen and whether it will be low-carbon from the start. The plan also includes solar and battery storage to complement the gas units, but timelines for scaling up to 100% hydrogen or ammonia are still distant.

Interesting move. 2.6 GW of gas capacity is a big bet on hydrogen availability. The 34% carbon intensity reduction claim needs scrutiny though. Where will the hydrogen come from? If it's grey hydrogen, net gains are smaller.

The 913 gCO2/kWh current average is high. Adding gas will help, but the real question is ramp rate and capacity factor. Also, hydrogen blends up to 30% on existing turbines? That's optimistic. Many sites need upgrades.

Net zero by 2060 is the national target. This fits. But they should clarify if the CCS pilot is actually funded. Also, gas as a bridge only works if methane leakage is controlled. Missing details on fuel sourcing.

They mention solar and battery storage complementing gas. That's good. But the timeline for 100% hydrogen or ammonia is far off. Would like to see intermediate milestones and how they'll source ammonia.
