Pertamina Geothermal Energy Launches Green Hydrogen Pilot Project in Ulubelu

PT Pertamina Geothermal Energy Tbk has initiated a green hydrogen pilot project in Ulubelu, aiming to produce approximately 100 kilograms of green hydrogen daily. This initiative is expected to set a precedent for future green hydrogen developments across the company's geothermal sites. Additionally, it will support Pertamina's downstream projects in green ammonia and green methanol, facilitating a transition to sustainable energy solutions. The company is simultaneously expanding its geothermal operations in Sumatra, with new power plants and feasibility studies underway.

PT Pertamina Geothermal Energy Tbk (PGE) has embarked on an innovative journey by launching a green hydrogen pilot project in Ulubelu, which aims to generate around 100 kilograms of green hydrogen each day. This initiative marks a significant step forward, as PGE's President Director, Julfi Hadi, envisions it not merely as a production facility but as a model for future green hydrogen projects across the company's various geothermal working areas.

The project's implications extend beyond hydrogen production; it lays a crucial foundation for PGE's ambitious downstream initiatives, which include the development of green ammonia and green methanol. These efforts, as articulated by Hadi, form an integral part of PGE's roadmap toward sustainable energy solutions.

Aloysius Mantiri, President Director of PT Pertamina Persero, emphasized the project's dual role as both a center for technological learning and a critical building block for a comprehensive national clean energy ecosystem. This aligns with Pertamina Group's overarching commitment to renewable energy development.

In parallel, PGE is actively expanding its geothermal capabilities in Sumatra. The inauguration of a 55-megawatt greenfield geothermal power plant at Mount Tiga is a testament to this growth, alongside the operational Lumut Balai Unit 2, which has already begun supplying electricity to the national grid. PGE is not resting on its laurels; plans are underway for Lumut Balai Unit 3, and exploration efforts for Unit 4 are in progress.

Looking ahead, the Hululais geothermal power plant project is set to be operational by late 2027 or early 2028, promising to further bolster Indonesia's clean energy landscape. As PGE forges ahead, its initiatives reflect a commitment to pioneering sustainable energy solutions, positioning the company as a leader in the transition towards a greener future.
