As part of DOE/NETL’s Carbon Sequestration Program, we are developing an integrated, multi-pollutant modeling framework to evaluate the costs and performance of alternative carbon capture and sequestration technologies for fossil-fueled power plants. The model calculates emissions, costs, and efficiency on a systematic basis at the level of an individual plant or facility. Both new and existing...

Cost effective carbon sequestration schemes have been identified as a key need for dealing with carbon dioxide's (CO 2) impact on global climate change. Two main approaches are being pursued for sequestration: the enhancement of biological carbon sinks, and the capture and storage of CO 2. Since the bulk of the cost in a capture and storage sequestration scheme stems from CO 2 separation and co...

What is carbon (C) sequestration? Carbon sequestration can be defi ned as the capture and secure storage of carbon that would otherwise be emitted to or remain in the atmosphere. The idea is to (1) prevent carbon emissions produced by human activities from reaching the atmosphere by capturing and diverting them to secure storage, or (2) remove carbon from the atmosphere by various means and sto...

carbon sequestration in soil, leaf and litter of three tree species, viz. eucalyptuscamaldulensis, prosopisjuliflora and ziziphus spina-christi, plantation was investigated in the dehloran city, iran. results showed that the amount of sequestered c in leaf, litter and soil was significantly different among these species. the highest amount of sequestrated c was in leaf and the lowest amount in ...

Terrestrial and oceanic ecosystems contribute almost equally to the sequestration of ca 50 per cent of anthropogenic CO(2) emissions, and already play a role in minimizing our impact on Earth's climate. On land, the majority of the sequestered carbon enters soil carbon stores. Almost one-third of that soil carbon can be found in peatlands, an area covering just 2-3% of the Earth's landmass. Pea...

soil is known as a suitable reservoir for carbon sequestration. the objective of this study was to investigate the capability of haloxylon on sequestration of carbon in sand dunes of yahya abad, sabzevar, in northeastern iran. eighty soil samples were taken from two depths of 0-5 and 5-10 cm under and between haloxylon trees. eight soil profiles under and between haloxylon trees were described ...

carbon sequestration potential of three species including agropyron elengatum, stipa barbata and artemisia aucheri was evaluated in parts of a semi-arid rangeland in this study. after determination and selecting key areas as study sites, sampling from vegetation and soil, based on randomized systematic method, was done and 90 plant and 45 soil samples were taken, respectively. shooting and root...
