Summary

This summary is machine-generated.

Onboard Carbon Capture and Storage (OCCS) offers solutions for ship emissions. Cryogenic and membrane separation are promising OCCS technologies, despite energy and cost trade-offs.

Area Of Science

  • Marine Engineering
  • Environmental Science
  • Chemical Engineering

Background

  • Maritime sector faces increasing pressure to reduce greenhouse gas (GHG) emissions.
  • Onboard Carbon Capture and Storage (OCCS) presents a viable strategy for mitigating CO2 emissions from ships.

Purpose Of The Study

  • To provide a comprehensive review of OCCS technologies for maritime applications.
  • To analyze recent developments, challenges, and future prospects of OCCS.

Main Methods

  • Critical analysis of various Carbon Capture (CC) methods: post-combustion, pre-combustion, and oxy-fuel combustion.
  • Evaluation of CO2 storage options: gaseous, supercritical, solid, and liquid states.
  • Comparative assessment of OCCS technologies for shipboard implementation.

Main Results

  • Post-combustion capture (chemical absorption) requires significant space compared to cryogenic and membrane separation.
  • Cryogenic and membrane separation are identified as viable OCCS options, each with specific energy consumption and cost considerations.
  • Solid and liquid CO2 storage methods show promise, with solid storage nearing commercial maturity.

Conclusions

  • OCCS technologies are crucial for decarbonizing the maritime sector.
  • Cryogenic and membrane separation represent the most promising OCCS approaches currently.
  • Further research is needed to optimize OCCS technologies for space, energy, safety, and economic viability in maritime settings.

Bioremediation is the use of prokaryotes, fungi, or plants to remove pollutants from the environment. This process has been used to remove harmful toxins in groundwater as a byproduct of agricultural run-off and also to clean up oil spills.

Agricultural Bioremediation

Bioremediation is a useful process in which microbes and bacteria are used to remove toxins and pollutants from the environment. In agricultural practices, the use of fertilizers and pesticides can result in leaching of...

The Carbon Cycle 01:14

36.9K

Carbon is the basis of all organic matter on Earth, and is recycled through the ecosystem in two primary processes: one in which carbon is exchanged among living organisms, and one in which carbon is cycled over long periods of time through fossilized organic remains, weathering of rocks, and volcanic activity. Human activities, including increased agricultural practices and the burning of fossil fuels, has greatly affected the balance of the natural carbon cycle.
