Wedoany.com Report-Sept. 18, PT Pertamina Geothermal Energy Tbk (PGE) has officially launched the Ulubelu Green Hydrogen Pilot Project, marking a significant step in the company’s push toward a low-carbon energy transition.

“This project is a crucial part of PGE's efforts to build an end-to-end green hydrogen ecosystem, from production and distribution to utilisation, to support the transition to a low-carbon industry,” the company said.

The Ulubelu project combines geothermal energy, a renewable resource, with modern, energy-efficient electrolysis technology to produce green hydrogen. The facility is designed to generate up to 100 kilograms of green hydrogen per day, with an efficiency rate of 82% to 88%.

PGE President Director Julfi Hadi highlighted the broader potential of the project: “This project could be a model that can be replicated in other geothermal working areas, whilst also opening up opportunities to accelerate off-grid solutions for transportation and low-carbon industries.” He added that the technology will be implemented in other PGE Geothermal Working Areas (WKP) in the future.

Beyond production, the facility serves as a centre for technological learning, commercial feasibility testing, and market research to assess potential demand in the next phase of development.

PGE is simultaneously advancing geothermal development across Sumatra through strategic initiatives. In the Ulubelu Geothermal Working Area, the company inaugurated the 55-megawatt (MW) Gunung Tiga Geothermal Power Plant, a greenfield exploration project. Additionally, PGE completed the key operational phase of the Lumut Balai Unit 2 Geothermal Power Plant, which now supplies electricity to the national grid.

The company is also conducting feasibility studies for further expansion, including the 55 MW Lumut Balai Unit 3 and an exploration feasibility study for a potential 55 MW Unit 4.

Through these initiatives, PGE aims to integrate geothermal energy with emerging low-carbon technologies such as green hydrogen, positioning itself as a leader in sustainable energy solutions. The company emphasises that the Ulubelu project not only advances renewable energy production but also provides a foundation for innovation, research, and the scaling of clean technologies across Indonesia.

With this project, PGE reinforces its commitment to creating an end-to-end green hydrogen ecosystem while supporting broader national goals of clean energy adoption and sustainable industrial development. By combining geothermal resources with advanced electrolysis, the company is developing a replicable model that could accelerate the use of off-grid renewable solutions for transportation and industry, enhancing both energy security and environmental sustainability.
