PLN Indonesia Power Advances Clean Energy with Hydrogen Cofiring Test

Successful Trial at Bali Power Plant

PLN Indonesia Power has successfully completed an advanced hydrogen cofiring trial at PLTDG UBP Bali Pesanggaran from November 18 to 20, 2025. The comprehensive test covered three load levels - 75%, 85%, and 100% machine capacity - achieving hydrogen cofiring ratios of 23%, 22%, and 17% respectively.

Technical Breakthroughs and Emissions Reduction

The testing demonstrated several key technical advancements:

1. Improved combustion efficiency: Total energy consumption (natural gas + hydrogen) was lower compared to pure natural gas combustion
2. Enhanced emission control: Lower carbon monoxide (CO) emissions were recorded during cofiring
3. Advanced hydrogen supply system: Implementation of Pressure Regulator System (PRS) based on PLC and HMI for more accurate and safe hydrogen injection

Strategic Implications for Energy Transition

This successful trial represents a crucial step in Indonesia's energy transition roadmap towards achieving Net Zero Emission by 2060. The technology demonstrates significant potential for reducing emissions in power generation while maintaining operational efficiency.

Future Prospects and Challenges

While the technical feasibility has been established, future implementation will depend on achieving economic viability. The ability to supply hydrogen continuously at competitive costs will be crucial for widespread adoption. PLN Indonesia Power's commitment to continuing innovation in this space positions the company at the forefront of clean energy technology in the region.
