Carbon Capture and Storage (CCS): Technologies and Applications

Carbon Capture and Storage (CCS) technologies represent a critical solution for decarbonizing industrial processes that are difficult to electrify. These systems capture CO2 emissions at their source—such as power plants or cement factories—before they enter the atmosphere, then transport and permanently store them underground. Current CCS approaches include:

• Post-combustion capture: Using chemical solvents to separate CO2 from flue gases
• Pre-combustion capture
• Oxy-fuel combustion: Burning fuel in pure oxygen to create concentrated CO2 streams

Notable projects demonstrate CCS scalability. The Gorgon CCS facility in Australia aims to store 4 million tons of CO2 annually, while China's Sinopec Qilu refinery captures 1 million tons yearly. In Hong Kong, CLP Power's feasibility study for CCS implementation at their Black Point Power Station represents local industry engagement. The International Energy Agency projects that CCS could contribute to 15% of global emissions reductions by 2070. However, challenges persist in reducing energy penalties (typically 15-25% of plant output) and costs (US$50-100 per ton of CO2). Professionals considering what is career trajectory in CCS might begin as chemical engineers before advancing to project management roles overseeing multi-billion dollar installations.

Renewable Energy: Wind, Solar, Hydro, and Geothermal

The transition to renewable energy constitutes the foundation of decarbonization efforts worldwide. Different technologies offer complementary advantages:
