Feasibility studies for carbon dioxide absorption by the ocean and coastal ecosystems, also known as “blue carbon” (i.e., seagrass, seaweed, seashell) aim to support achieving the goal of net zero greenhouse gas emissions by 2050 or “EP Net Zero 2050” for PTTEP. The Company foresees an opportunity in capturing carbon dioxide from the blue carbon to use as the offset for greenhouse gas emissions to achieve the “Net Zero” target. PTTEP believes that the biodiversity abundance and ecosystems improvement lead to availability of robust carbon sinks.
The project is a joint study with Kasetsart University regarding techniques for expanding seagrass areas and potential areas to grow seagrass in the Gulf of Thailand. Three techniques are used for seagrass plantation: seeding, isolation, and tissue culture. The project seeks to study the survival rate of seagrass grown in real environments around Koh Taen and Koh Samui, Surat Thani Province and to establish baseline data on carbon dioxide storage in the seagrass planting areas. PTTEP also plans to expand cooperation with the Department of Marine and Coastal Resources on additional seagrass planting in Koh Samui, Surat Thani Province.
In addition, PTTEP collaborates with Chulalongkorn University to study the carbon dioxide absorption from suitable native species of seaweeds and seashells in the Gulf of Thailand and cultivating them in the laboratory prior to actual hatchery in the Gulf of Thailand.
