U.S. oil major Exxon Mobil (XOM.N) is wanting to put up to $15 billion in a petrochemical task and carbon capture and storage (CCS) offices in Indonesia, President Joko Widodo said in an official castle proclamation on Thursday.

The arranged CCS offices would be the greatest in Southeast Asia. Jokowi, as the Indonesian president is usually known, met with Exxon Director Darren Woods during an outing to San Francisco for an Asia Pacific Financial Collaboration (APEC) highest point.

Recently, Indonesia marked an underlying arrangement with an Exxon unit to investigate interest in a petrochemical project in Indonesia to deliver polymers.

Exxon and Indonesian state energy organization Pertamina likewise consented to assess $2 billion in interests in CCS offices involving two underground bowls in the Java Ocean.

“These large-scale opportunities could substantially boost industrial growth and decarbonisation in Indonesia, as well as the Asia Pacific region,” said Carole Nerve, leader of Exxon Mobil Indonesia.

The CCS center point would can possibly store something like 3 gigatons of carbon dioxide transmitted by businesses in Indonesia and the remainder of the district, Pertamina said.

Indonesia needs to involve its drained oil and gas supplies for carbon capacity and is concluding a guideline that would open up stockpiling plans for carbon from abroad to be put away in the country.

The arrangements were endorsed during Jokowi’s visit to Washington to meet with U.S. President Joe Biden, in front of the APEC highest point in San Francisco this week.
