Techno-Economic Optimization of Excess Green Hydrogen Production at Tanjung Jati B Coal Fired Power Plant
Keywords:
Green Hydrogen, Excess Hydrogen, Coal Fired Power PlantAbstract
With the increasing global demand for energy, the level of emissions and the impact of energy growth on ecosystems and climate change have become major global issues. In this context, green hydrogen offers a promising clean and sustainable energy solution.
This study analyses the feasibility of the hydrogen production system at the existing Hydrogen Plant of the Tanjung Jati B coal-fired power plant (TJB CFPP) to produce excess hydrogen gas categorized as green hydrogen. Integration of current electrolysis systems with solar energy sources will play a pivotal role in this study. This study employs a quantitative approach by collecting data from previous studies and operational reports from the TJB CFPP.
This study investigates six optimization scenarios for excess green hydrogen production, each combining electricity sources with electrolysis technologies. The integration of available electrolysis systems with an existing solar power plant has demonstrated the potential to produce excess green hydrogen at a competitive Levelized Cost of Hydrogen (LCOH). Notably, one scenario achieves an LCOH close to 4 USD/kg, significantly lower than the current average green hydrogen LCOH in Indonesia, which stands around 10 USD/kg.
