Gearing Toward CCUS for CO2 Reduction in Malaysia

Abstract PETRONAS has embarked on Research & Development (R&D) of Carbon Capture, Utilization and Storage (CCUS) related technologies since 2011. The main purpose in pursuing R&D in this area is to monetize high CO2 gas fields through technology development. At initial stage, area that has been focusing were on capture, transportation and storage only. Later, utilization became an area of focus since there is a need to convert CO2 to valuable product in order to make high CO2 gas fields development more viable. R&D in the area of CO2 capture namely advanced membrane separation, advanced cryogenic distillation as well as supersonic technologies were conducted. For ultra high CO2 gas field (> 50 mol% CO2), a hybridization of separation technology are key to ensure economic viability of the fields development. In term of CO2 storage, several critical areas has been studied especially wells drilling technology, CO2 injectivity, storage technology involving geomechanic & geochemistry fields model and measurement as well as monitoring and verification technologies for the stored CO2. CO2 mineralisation technology is also explored to convert CO2 into valuable product. Furthermore, K5 Strategic Technology Project is undertaken in order to showcase and prove all the newly develop technologies.
