Highlights

• PTTEP announces Thailand’s first CCS project at Arthit gas field; operations to begin in 2028.
• The aim is to capture and store up to 1 million tonnes of carbon dioxide per year.
• Recognised under Thailand’s NDC Action Plan, this initiative has government backing and also aims to support Net Zero targets.

PTT Exploration and Production (PTTEP) has approved its first Carbon Capture and Storage (CCS) project at the Arthit gas field, which marks Thailand’s entry into CCS technology.

This step is tied to the country’s Net Zero goal, which aims to cut greenhouse gas emissions pursuant to international climate commitments.

According to PTTEP, the Arthit CCS Project is designed to capture and store up to 1 million tonnes of carbon dioxide annually.

Operations are scheduled to begin in 2028, with a five-year investment of about THB 10 billion (USD 320 million). The captured carbon dioxide will be injected into deep underground reservoirs, located between 1,000 and 2,000 metres below the surface.

More importantly, the company confirmed that the development will not affect natural gas production at the field.

The Thai government has recognised the project under the Nationally Determined Contribution (NDC) Action Plan 2021–2030. This endorsement allows PTTEP to coordinate with government agencies on measures such as tax incentives and investment support.

The project will also act as a pilot model for future initiatives, including the proposed Eastern CCS Hub in the Gulf of Thailand, which could cut emissions on a larger scale.

In preparation, PTTEP has conducted detailed studies covering site selection, engineering design, and monitoring programmes. By using existing infrastructure at Arthit, alongside new facilities, the company aims to gradually increase the storage capacity to the planned level of 1 million tonnes of CO₂ each year.

The CCS process works as a reverse of petroleum production: while gas is extracted for energy, excess carbon dioxide is returned underground for safe storage.

Apart from CCS, PTTEP is also venturing into other emission reduction efforts, which include reusing excess gas, improving production efficiency, expanding renewable energy use, and focusing on low-carbon projects.

Besides, the company has carried out reforestation and mangrove planting to create green spaces that naturally absorb carbon dioxide. Together, these measures indicate a wider strategy to balance energy security with climate goals.
