Feasibility studies for carbon dioxide absorption by blue carbon (seagrass, seaweed and seashell)
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 PTTEP’s Net Zero Greenhouse Gas Emissions by 2050 under “EP Net Zero 2050” concept. The Company foresees an opportunity in capturing carbon dioxide from the ocean to use as the offset to achieve the Net Zero target.
The project focuses on the study of the potential area of the seagrass plantation in the Gulf of Thailand and seagrass plantation techniques with collaboration of Kasetsart University through the pilot seagrass plantation with 3 techniques, including seed propagation, isolation, and tissue culture. This project aspires to study the survival rate of the pilot seagrass plantation around Koh Taen and Koh Samui, Surat Thani Province as well as establishing a baseline of carbon dioxide sequestration in such a plantation. Furthermore, PTTEP is extending the project through the collaboration with the Department of Marine and Coastal Resources (DMCR) to pilot seagrass plantation in Koh Samui, Surat Thani Province.
In addition, PTTEP collaborated with Chulalongkorn University to seek new carbon capture from potential native marine species such as seaweeds and seashells in the Gulf of Thailand by determining which species can absorb and store the most carbon amount and grow well in the Gulf of Thailand before cultivating them in a laboratory in preparation for a future pilot-scale hatchery in the targeted area.
