2. Tackling Climate Change: Carbon Capture, Utilization, and Storage (CCUS)

Climate change, driven by the accumulation of greenhouse gases in the atmosphere, poses an existential threat to the planet. The burning of fossil fuels for energy production is the primary source of these emissions, with carbon dioxide (CO2) being the most significant contributor.[3] While transitioning to renewable energy sources is crucial, it is also essential to develop technologies that can capture CO2 from industrial sources and the atmosphere and prevent it from further contributing to global warming. This is where Carbon Capture, Utilization, and Storage (CCUS) comes into play.[4]

2.1. Carbon Capture Technologies:

Carbon capture technologies aim to separate CO2 from other gases in industrial flue streams or directly from the air (Direct Air Capture, DAC). Several different approaches are being pursued, each with its own advantages and disadvantages:

• Absorption: This is the most mature and widely used carbon capture technology. It involves using a liquid solvent, typically an amine solution, to absorb CO2 from the gas stream. The CO2-rich solvent is then heated to release the CO2, which can be compressed and stored or utilized.[5]
  • Advantages: Relatively well-established technology, commercially available.
  • Disadvantages: High energy consumption for solvent regeneration, potential for solvent degradation.
• Adsorption: This method uses solid materials, such as zeolites, activated carbon, or metal-organic frameworks (MOFs), to selectively adsorb CO2 onto their surface. The CO2 is then released by changing the pressure or temperature.[6]
  • Advantages: Lower energy consumption than absorption, potentially more environmentally friendly.
  • Disadvantages: Adsorbent capacity can be limited, sensitivity to moisture and other contaminants.
• Membrane Separation: This technology uses selectively permeable membranes to separate CO2 from other gases. The driving force for separation is a pressure or concentration gradient across the membrane.[7]
  • Advantages: Relatively low energy consumption, compact design.
  • Disadvantages: Membrane performance can be affected by temperature and pressure, limited CO2 selectivity.
• Direct Air Capture (DAC): DAC technologies aim to capture CO2 directly from the atmosphere. This is particularly important for addressing historical emissions and for capturing CO2 from dispersed sources.[8]
  • Advantages: Can be deployed anywhere, can address historical emissions.
  • Disadvantages: Very energy intensive, high cost.

2.2. Carbon Utilization:

Once CO2 is captured, it can be utilized as a feedstock for the production of various valuable products, effectively turning a waste product into a resource. This approach not only reduces CO2 emissions but also creates new economic opportunities.[9]

• Chemical Conversion: CO2 can be chemically converted into fuels, chemicals, and materials using various catalytic processes. For example, CO2 can be converted into methane, methanol, or other hydrocarbons using hydrogen.[10] It can also be used to produce polymers, building materials, and other valuable products.
  • Challenges: Requires efficient and selective catalysts, often requires high energy input.
• Enhanced Oil Recovery (EOR): CO2 can be injected into oil reservoirs to enhance oil recovery. This process can increase oil production and also store CO2 underground.[11]
  • Challenges: Can be expensive, potential for leakage from reservoirs.
• Mineral Carbonation: CO2 can be reacted with minerals, such as magnesium oxide or calcium oxide, to form stable carbonates. These carbonates can be used as building materials or disposed of safely.[12]
  • Challenges: Requires large amounts of minerals, slow reaction rates.

2.3. Carbon Storage:

When CO2 cannot be utilized, it can be stored underground in geological formations. This involves injecting CO2 into deep saline aquifers, depleted oil and gas reservoirs, or unminable coal seams.[13] The CO2 is then trapped underground by impermeable layers of rock.

• Challenges: Potential for leakage from storage sites, requires careful site selection and monitoring.

The successful implementation of CCUS requires a multi-faceted approach, including continued research and development of more efficient and cost-effective technologies, supportive government policies, and public acceptance.
