Electricity Supply for Hydrogen Plant through Power Swap Based Reliability and Risk Case Study Pertamina Power's Electrolyzer in Sumatra

Abstract : This research investigates the integration of renewable energy sources into hydrogen production in Sumatra, with a focus on the utilization of power swap mechanisms to ensure energy reliability and effectively manage risks. This study is in line with the ongoing collaboration between PT. Pertamina, Chevron New Energies International Pte Ltd, and Keppel Infrastructure, which aims to develop hydrogen production facilities using renewable energy through electrolysis. The main objective is to assess the reliability and risk management in renewable energy-powered hydrogen production, with a focus on the operational reliability of geothermal and solar power plants and the effectiveness of the power swap system. The methodology combines theoretical and empirical approaches Reliability Evaluation using metrics such as power balance, load flow analysis and Monte Carlo Simulation to analyze the variability and risks in the power generation and swapping system, improving the understanding of system behavior under various scenarios, and Data Analysis through statistical analysis of data collected from ETAP simulations to see patterns. This study hypothesizes that high reliability of renewable energy sources and an effectively managed power swap system can significantly improve the stability and sustainability of hydrogen production. It is expected that the implementation of strategic power exchange can reduce the risks associated with renewable energy variability, thereby strengthening the overall stability of energy supply for hydrogen production. This study aims to provide insights and actionable recommendations to improve system efficiency and reliability, providing valuable perspectives for the discourse on renewable energy utilization and hydrogen production in Indonesia.
