Even as the acceptance of the fossil fuel greenhouse effect theory continues to grow amongst academics, statesmen and plebeians alike, the early adopters have already engaged in pre-emptive research activities aimed at mitigating the effects of such greenhouse gases. The focus of one such effort is on the capture and storage of CO2 (carbon dioxide) from anthropogenic fixed source emissions. Thi...

This framework is constructed based on in depth understanding of the physics in the parameter space of interest for geologic sequestration of CO2, accurate and computationally efficient numerical algorithms for modeling of highly detailed descriptions of large-scale porous formations, and a flexible extensible computational framework for the optimization of real CO2 projects during both the inj...

Problem: Most research on planning to mitigate climate change has focused on reducing CO2 emissions from coal-fıred power plants or the transportation sector. The contribution of forests to lowering net CO2 emissions has largely been overlooked. U.S. forests already offset about one eighth of the nation's annual CO2 emissions and have the potential to offset more, all at a relatively low cost. ...

Proper characterizations of background soil CO2 respiration rates are critical for interpreting CO2 leakage monitoring results at geologic sequestration sites. In this paper a method is developed for determining temperature-dependent critical values of soil CO2 flux for preliminary leak detection inference. The method is illustrated using surface CO2 flux measurements obtained from the AmeriFlu...

This paper has been presented at an expert meeting on CO2 capture technology learning at the IEA headquarters, January 24th 2003. The electricity sector is a key source of CO2 emissions and a strong increase of emissions is forecast in a business-as-usual scenario. A range of strategies have been proposed to reduce these emissions. This paper focuses on one of the promising strategies, CO2 capt...

The multiphase nature of the flow in porous media is characterized by hysteretic effects on the macroscopic level. These effects have a significant influence on the behavior of the whole system and therefore have to be taken into account. The aim of this subproject is to develop and implement models describing the hysteresis in the context of the CO2 sequestration process.The hysteresis relatio...

An international collaboration to investigate the sequestration of COz in the deep ocean was initiated in December 1997. The program is being funded by agencies of the governments of Japan, the U.S., Norway, Canada, and Australia; and Asea Brown Boveri (ABB) of Switzerland. The investigation comprises both experimental and modeling components. During the first phase of the program which runs th...

growing process of industrialization in different societies, excessive expansion of industries and factories and increase transport industries, push human toward unstable development. among these problem, massive volume of pollutions is also added to the atmosphere. air pollution in industrial societies and cities is more intensive. global warming is one of the major problems of 21 century. co2...

Wetlands present an important opportunity for carbon sequestration and greenhouse gas offsets by virtue of their potential for restoration using known and innovative land management methods, because inherently they are highly productive and accumulate large below-ground stocks of organic carbon. Wetlands are major carbon sinks. While vegetation traps atmospheric CO2 in wetlands and other ecosys...
