Abstract

Meningkatnya permintaan energi global, khususnya pada sektor energi listrik mengakibatkan emisi Gas Rumah Kaca (GRK) meningkat, terutama energi listrik yang dihasilkan dari pembangkit listrik yang berbasis bahan bakar fosil. Salah satu upaya dekarbonisasi adalah penerapan potensi gas hidrogen sebagai bahan bakar alternatif yang menjanjikan karena karakteristiknya yang bersih dan potensinya yang dapat mengurangi emisi karbon dengan melakukan hydrogen assisted combustion atau co-firing hydrogen pada sistem Pembangkit Listrik Tenaga Gas (PLTG). Penelitian ini bertujuan untuk menganalisis pengaruh penambahan hidrogen terhadap kinerja dan emisi pada turbin gas Blok 3-4 Muara Tawar tipe SGT5-S2000E v94.2 dengan pendekatan analisis termodinamika menggunakan perangkat lunak DWSIM. Variasi fraksi mol hidrogen yang digunakan adalah 10%, 20%, dan 30% terhadap bahan bakar natural gas. Hasil simulasi menunjukkan bahwa seiring meningkatnya fraksi mol hidrogen yang digunakan, hal tersebut dapat meningkatkan daya keluaran turbin sebesar 2,2%, 5%, dan 8%. Selain itu, emisi CO2 berkurang secara signifikan sebesar 1,3%, 3%, dan 5% tanpa perlu memodifikasi infrastruktur yang ada. Hal ini menunjukkan bahwa teknologi hydrogen assisted combustion dapat meningkatkan kinerja pembangkit listrik sebesar 1%, 2%, dan 4% sekaligus dapat mengurangi emisi. Penelitian ini diharapkan dapat mendukung transisi energi bersih yang rendah karbon dan mitigasi perubahan iklim di Indonesia dan menjadi acuan dalam implementasi teknologi hydrogen assisted combustion pada PLTG.

The increasing global demand for energy, particularly in the electricity sector, has contributed to a rise in greenhouse gas (GHG) emissions, especially from fossil fuel-based power generation. One potential decarbonization strategy is the utilization of hydrogen as a promising alternative fuel due to its clean characteristics and its potential to reduce carbon emissions through hydrogen-assisted combustion or hydrogen co-firing in gas turbine power plants. This study aims to analyze the effects of hydrogen addition on the performance and emissions of the SGT5-2000E V94.2 gas turbine installed at Blocks 3–4 of the Muara Tawar Power Plant using a thermodynamic analysis approach with DWSIM software. Hydrogen mole fractions of 10%, 20%, and 30% were blended with natural gas. The simulation results indicate that increasing the hydrogen mole fraction increased the turbine power output by 2.2%, 5%, and 8%, respectively. In addition, CO₂ emissions were significantly reduced by 1.3%, 3%, and 5%, respectively, without requiring major modifications to the existing infrastructure. The implementation of hydrogen-assisted combustion also improved overall power plant performance by approximately 1%, 2%, and 4% for the corresponding hydrogen fractions while simultaneously reducing carbon emissions. These findings demonstrate that hydrogen-assisted combustion has considerable potential to support Indonesia’s transition toward a cleaner and low-carbon energy system, contribute to climate change mitigation, and serve as a reference for the future implementation of hydrogen co-firing technology in gas turbine power plants.
