Mechanisms and management for soil carbon sequestration
Soil organic matter (SOM) holds more carbon (C) than the atmosphere and terrestrial aboveground biomass combined. SOM also provides many other co-benefits in the form of ecosystem services. The rate at which we lose or sequester more C in soils is of great importance for mitigating the rising …

Green Chimney - Localized Carbon Sequestration in closed Environment
… ways to minimize 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 …

Reactivity of Iron-Bearing Minerals Under Carbon Sequestration Conditions
The rise in anthropogenic carbon dioxide in the atmosphere has caused the pursuit of adequate methods to alleviate the resulting strain on the world's ecosystem. A promising strategy is the geological sequestration of carbon dioxide, in which carbon dioxide emitted from large point sources is …

Carbon Sequestration in Tidal Salt Marshes and Mangrove Ecosystems
… and services. Wetlands take part in the global carbon cycle by holding organic carbon in biomass, soils and 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 …

Spatial provenance: A case study on geological carbon sequestration
… Using a case study based on geological carbon sequestration research, this thesis examines source data revisions and updates to a spatial analysis over time. Experiments in tracking the spatial propagation of potential errors and comparing temporal attributes of alternative workflows of …

Forest carbon sequestration programs : reviewing and assembling Mexican efforts
This thesis examines current efforts to sequester carbon dioxide in the forests in Mexico. A brief review of the most relevant examples worldwide is also included in order to explain the international context and introduce some key concepts. The decision regarding the desirability of pursuing …

Effects of Biosolids on Carbon Sequestration and Nitrogen Cycling
… in soils, but the effects of biosolids on C sequestration and N cycling in the Mid-Atlantic region is not well understood. The objectives were: 1) to investigate soil C sequestration at sites with a long-term history of biosolids either in repeated application or single large application; 2) …

Modeling carbon sequestration in transition zone to optimize storage potential
<p>"Shallow aquifers are potential candidates for carbon sequestration because of their wide distribution and low injection cost. Injected CO₂ in a shallow region segregates into two zones according to CO₂ phases within the initial reservoir pressure and the maximum bottom hole pressure: gas zone …

Implications of geological carbon sequestration on shallow freshwater aquifers geochemistry
… of scale and storage potential, is geological carbon capture, utilization and storage (CCUS). However, while acting to solve one environmental problem, CCUS operations are accompanied by other environmental concerns associated with CO2 and brine leakage from injection formations. In this work, …

Multi-scale Investigations of Geological Carbon Sequestration in Deep Saline Aquifers
Geological carbon dioxide (CO2) sequestration (GCS) in deep saline aquifers is viewed as a viable solution to dealing with the impact of anthropogenic CO2 emissions on global warming. The trapping mechanisms that control GCS include capillary trapping, structural trapping, dissolution trapping, and …

Carbon Sequestration Through the Production of Precipitated Calcium Carbonate From Waste Concrete
… activities, rising concentrations of atmospheric carbon dioxide (CO2) are causing climate change. One method to sequester CO2 involves the production of synthetic limestone (CaCO3) from calcium silicate minerals and CO2 via mineral carbonation. Certain grades of CaCO3, including Precipitated …

Carbon sequestration in short-rotation forestry plantations and in Belgian forest ecosystems
In deze studie werd nagegaan in hoeverre plantages met een korte omloopstijd en Belgische bossen kunnen bijdragen tot het bereiken van de broeikasgasemissiereductiedoelstelling die de Belgische overheid aangegaan is onder het Kyoto Protocol.

Caprock characteristics and uncertainties in geological carbon sequestration in the Illinois basin
Geological carbon sequestration in deep saline aquifers has emerged as a promising mitigation strategy for reducing greenhouse gas emissions to the atmosphere. Success of commercial-scale GCS requires containment of injected CO2 and the sealing ability of the overlying caprock has been identified …

Tillage Effects on Soil Organic Carbon Sequestration: Carbon Inputs and Physical Protection
… and physical protection by aggregates on C sequestration. Simulated results were compared against actual C contents; both showed that after a decade of NT practice adoption, C input patterns and soil aggregation could explain SOC contents that were increased at the surface and decreased in …

Studies of Lagrangian modeling techniques with applications to deep ocean carbon sequestration
… the efficacy and marine impact of ocean CO2 sequestration by direct injection. The first study compares RWPT to two other simple Lagrangian techniques (forward and backward Gaussian puff tracking) to simulate mixing beyond the near field of a pollutant discharge. RWPT is found to be more …

Geophone Array Optimization for Monitoring Geologic Carbon Sequestration using Double-Difference Tomography
… tomographic monitoring system for a geologic carbon sequestration injection site. Artificial velocity models were created that accounted for the expected velocity decrease due to the existence of a CO₂ plume after underground injection into a depleted petroleum reservoir. Seismic events were …
