Carbon Capture and Storage at Malaysia Power Plants: Evaluation of its Feasibility and Requisite Enablers

Rapidly growing GHG emissions are significantly altering the world climate, necessitating a global decarbonization efforts to avert irreversible catastrophic failure of the world ecosystem. Malaysia is pledging to achieve carbon neutrality by 2050 and has subsequently identified Carbon Capture and Storage (CCS) as one of the solutions for carbon removal from its energy sector by 2050. However, the implementation of CCS presents formidable challenges, encompassing both technical and commercial complexities, especially for a nation like Malaysia, which has limited experience in large-scale CCS deployment. This study evaluates the feasibility of CCS implementation in Malaysia's fossil fuel power plants by conducting a comprehensive techno-economic assessment, taking into considerations the prevailing energy landscape of the country. This assessment is very crucial to demonstrate the feasibility of this plan within the timeframe, considering the limited research have been done to assess a national-scale implementation, as well as to provide the important insights for future policy implication to promote CCS adoption. The CCS scenarios are assessed through an analytical approach, and comparative analyses are conducted between alternative paths. The result shows that a large-scale implementation of CCS at Malaysia’s fossil fuel power plant to achieve net-zero emission by 2050 are feasible given a strong enforcement on emission policy and establishment of CCS legal framework. CCS can potentially reduce 60% of Malaysia’s energy sector total emissions, and a solar-supported CCS helps to reduce it further. Levelized Cost of Electricity analysis reveals that the implementation of CCS leads to only a minimal increase between pre- and post-CCS LCOE when carbon price is considered. A SWOT-PESTLE analysis was also conducted to identify gaps in regulatory framework, financial and social aspects. It can be concluded that CCS is a techno-economically viable solution, however Malaysia’s readiness for CCS implementation is still at a very novice stage, and aggressive actions are needed to enable a successful full-scale implementation.
