Carbon capture and storage (CCS) is vital for reducing CO₂ emissions and achieving climate change targets. Despite proven technical viability, the high cost of current CO₂ capture methods hinders widespread applications of CCS. Hydrate-based carbon capture (HBCC) is a promising route for energy-efficient CO₂ capture. With an estimated cost of 20 – 40 US$/tonnes of CO₂ avoided and an energy penalty of 15%, HBCC is potentially competitive compared to the current capture via conventional absorption (40 – 100 US$/tonnes of CO₂ avoided and energy penalty of 30%). HBCC has a competitive edge at industrial scales owing to several intrinsic advantages: (i) a water-based process, (ii) tolerance to impurities in the feed gas, and (iii) potential energy savings via integrating hydrate formation/dissociation enthalpies. However, slow kinetics and limited industrial experience are current challenges to deployment …
