PT Pertamina launches geothermal-based green hydrogen project

September 18, 2025 |

In Indonesia, Asian Power reported that PT Pertamina Geothermal Energy (PGE) has launched the Ulubelu Green Hydrogen pilot project.

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

The Ulubelu green hydrogen project is a clean energy development initiative that utilizes a combination of geothermal energy as a renewable energy source and modern, more energy-efficient electrolysis technology. This facility is designed to produce up to 100 kilograms of green hydrogen per day with a high efficiency rate of 82% to 88%.

PGE President Director Julfi Hadi said the 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.”

Julfi said this technology will be adopted in various other PGE Geothermal Working Areas (WKP) in the future, according to the report.
