CO2 Sequestration through Mineral Carbonation
Anthropogenic greenhouse gas emissions have become a subject of increasing concern because of their association with global climate change. Carbon dioxide (CO2) is the most prevalent anthropogenic greenhouse gas, and hence reduction of CO2 concentration in the atmosphere has become an important …

Mechanisms and management for soil carbon sequestration
… can all come into play when determining the sequestration potential of a specific ecosystem. Additionally, not all soil C is equal in its turnover time or in its ability to resist disturbance. Therefore it is crucial that we better understand how functionally different soil C pools form and …

CO2 sequestration using brine impacted fly fish
It was hypothesized that South African FA and brine could sequester CO2 through mineral carbonation. A statistical approach was undertaken to optimize the % CaCO3 formed from FA/brine/CO2 interaction with input parameters of temperature, pressure, particle size and solid/liquid ratio (S/L) being …

Ion sequestration particles for naval anticorrosion coatings
… describes in detail the synthesis of Ion Sequestration Particles (ISP) that when added to the standard MIL-DTL-24441 or potentially another coating system act to enhance the anticorrosion properties of the coating. A solid ion sequestration core material (SISCM) is first produced. The core …

Green Chimney - Localized Carbon Sequestration in closed Environment
… GHG level in the atmosphere, Carbon Capture and Sequestration (CCS) has been widely considered as an effective way to reduce carbon dioxide (CO2) from fossil fuel emission. One of the CCS options is the use of biological means through forest carbon sink that is only able to absorb CO2 at …

Statistical approaches to leak detection for geological sequestration
Geological sequestration has been proposed as a way to remove CO₂ from the atmosphere by injecting it into deep saline aquifers. Detecting leaks to the atmosphere will be important for ensuring safety and effectiveness of storage. However, a standard set of tools for monitoring does not yet exist. …

Marine transportation for Carbon Capture and Sequestration (CCS)
The objective of this report is to determine whether opportunities to use liquefied carbon dioxide carriers as part of a carbon capture and storage system will exist over the next twenty years. Factors that encourage or discourage the use of vessels are discussed. This study concludes that …

Reactivity of Iron-Bearing Minerals Under Carbon Sequestration Conditions
… A promising strategy is the geological sequestration of carbon dioxide, in which carbon dioxide emitted from large point sources is injected underground for storage. Under storage, carbon dioxide trapped as a carbonate mineral may be stable for geological time periods. Experiments were …

Mineral sequestration of CO2 by reaction with alkaline residues
… a novel approach to achieve a long-term mineral sequestration of CO2 was studied, using alkaline residue materials. This study examined for the first time a process that allows for rapid removal of CO2 from flue gas through reaction with lignite fly ashes in aqueous solution. In this process the …

Sequestration of metal and metalloid ions by thermophilic bacteria
This Ph. D. thesis presents results and conclusions from studies 1) investigating the interaction between metal and metalloid ions and thermophilic bacteria, and 2) characterizing microbial populations in a geothermally active habitat with relatively high concentrations of metalloid ions and …

Carbon Sequestration in Tidal Salt Marshes and Mangrove Ecosystems
… sediments. In recent years, the wetland carbon sequestration capacity has been researched worldwide due to the increase of the concentrations of greenhouse gasses implicated in global warming and climate change. Although coastal wetlands release the greenhouse gasses carbon dioxide, methane and …

Carbon capture and sequestration : an option to buy time?
… of technology option of Carbon Capture and Sequestration (CCS) to climate change mitigation. CCS means that CO2 is captured at large industrial facilities and sequestered in goelogical structures. The technology uses the endogenous growth model MIND. Herein the various climate change …

Geomechanical Stability Analysis for Co2 Sequestration in Carbonate Formation
… pillars to build up the confidence of geological sequestration of CO2. Large scale CO2 sequestration in deep carbonate formation is a complicated geological process, which will non-reversibly transform the presumed equivalent and stable status of a sedimentary basin that formed over millions of …
