Carbon capture, storage, and utilisation: decarbonisation pathways for Singapore’s industry
Synopsis: Guidehouse (formerly Navigant) evaluated the potential for Carbon Capture Storage and Utilisation (CCSU) technologies to abate greenhouse gas emissions from the energy and chemicals sectors in Singapore. Geological storage potential in neighbouring countries indicate regional storage potential is an estimated 85 giga tonnes. For CO2 utilization, 49 identified CCU technologies were assessed to select the ten technologies that are most promising for Singapore to explore further. By 2050, all ten shortlisted CCU technologies may reach maturity. Their net abatement potentials range between 0.3 – 2,000 kilo tonnes of CO2, based on one reference plant per technology. All technologies with substantial abatement potential require significant amounts of hydrogen or ammonia. For CCU technologies to be effective climate mitigation measures, this feedstock needs to be low-carbon. It is important to explore the future availability and costs of these low-carbon commodities.
