The Singapore-based units of the two companies, ExxonMobil Asia Pacific Pte. Ltd. and Shell Singapore Pte. Ltd., have formed the S-Hub consortium to work with the Singapore government as lead developers for the CCS project to reduce the country's carbon dioxide (CO2) emissions.

"S-Hub and the Singapore Economic Development Board (EDB) signed a memorandum of understanding in December 2023 to coordinate the planning and development of a CCS project, capable of capturing and permanently storing at least 2.5 million tons of CO2 a year, by 2030," they said in a joint statement.

The project will store CO2 emissions from Singapore deep underground or under the seabed. The storage sites will be selected after undergoing analysis to ensure suitability, it added.
