Pertamina Hulu Energi Offshore North West Java (PHE ONWJ) has established cooperation with three South Korean companies − Posco International, Korea National Oil Corporation (KNOC) and Korea Maritime and Ocean University Consortium (KMOUC) − for the development of carbon capture and storage (CCS) technology and reuse of offshore platforms to support energy supply chain.

POSCO International Corporation is South Korea's largest trading company, primarily engaged in the trade of iron ore, both domestically produced and imported.

KNOC is South Korea's national oil company responsible for managing the country's oil reserves and developing energy resources in South Korea. KNOC plays a key role in ensuring national energy security through oil and gas exploration and production, both domestically and internationally.

Meanwhile, KMOUC is a leading educational and research institution in South Korea that focuses on marine and maritime sciences. KMOUC plays a role in the development of marine-related technology and research, including the exploration and utilization of marine resources.

This initial step of the collaboration was marked by the signing of a Confidentiality Agreement in early February 2025.

Muzwir Wiratama, General Manager of PHE ONWJ, said that this collaboration is important in supporting the energy transition and sustainable development.

"This initiative is expected to have a long-term positive impact in reducing the carbon footprint, changing the way we view energy production, and reusing infrastructure to support national energy security," Wira said on Sunday, March 2, 2025.

He said the development of CCS technology aims to capture carbon dioxide (CO2) emissions, then store them in a safe location so they are not released into the atmosphere. This is one solution to reduce greenhouse gas emissions and help mitigate climate change.

Meanwhile, the focus of the scope of cooperation with Posco International is the CCS feasibility study in Indonesia, especially in the PHE ONWJ offshore oil and gas operations area.

This study will evaluate the CO2 storage potential in saline aquifers and depleted reservoirs, utilizing subsurface and surface data from PHE ONWJ.

"This study is expected to provide added value for Indonesia and South Korea in their energy transition efforts," he said.

In addition, in collaboration with KNOC, PHE ONWJ will explore the use of offshore platforms for subsurface CO2 storage.

On the other hand, in collaboration with KMOUC, PHE ONWJ will explore alternative methods for offshore platform decommissioning, including conversion to Liquified Natural Gas (LNG) facilities and CO2 storage. Through this study, it aims to extend the life cycle of existing infrastructure, as well as provide economic and environmental benefits.

This two-year collaboration agreement is the beginning of a series of energy transition initiatives that are expected to realize the achievement of sustainable development goals, especially in the energy sector.
