Post-combustion carbon capture refers to the installation of an on-site carbon dioxide (CO2) capture unit to capture CO2 from waste gas produced during the combustion of natural gas in CCGTs.
Meanwhile, pre-combustion carbon capture involves installing an on-site CO2 capture unit to capture CO2 generated during the production of hydrogen from natural gas. The hydrogen would then be combusted in CCGTs to generate power.
“Both pathways involve capturing the carbon dioxide produced and storing them in underground CO2 storage sites,” says EMA in an Oct 21 announcement.
Deputy Prime Minister Gan Kim Yong announced the grant call in his opening lecture at the Singapore International Energy Week (SIEW) 2024 on Oct 21. “These studies would allow us to better understand the cost and infrastructure requirements for capturing the emissions from our combined-cycle gas turbines,” says Gan.

To be eligible for the grant call, participants should be operating or bidding to operate a H-class CCGT on Jurong Island or Tuas by 2035. In addition, they must have completed a pre-feasibility study for either the post-combustion carbon capture or pre-combustion carbon capture pathway.
According to EMA, participants’ proposals will be evaluated based on three main criteria: the amount of additional land required, the quality of the proposal and the funding requested from EMA.
Interested parties should submit their proposals by Jan 31, 2025.

EMA says the call is part of its efforts to explore power sector CCS pathways to help achieve Singapore’s net zero emissions target by 2050, while meeting the country’s growing energy demand.
The Singapore government is also developing a carbon capture and storage project to aggregate CO2 emissions on Jurong Island for overseas storage, with the first phase “likely to start around 2030”, says EMA. “If proven feasible, these power sector CCS pathways could potentially leverage future phases of the Jurong Island cross-border CCS project.”
