Update on the International Experiment on Co2 Ocean Sequestration
نویسندگان
چکیده
The specific objective of our project on CO2 ocean sequestration is to investigate its technical feasibility and to improve the understanding of any associated environmental impacts. Our ultimate goal is to minimize any impacts associated with the eventual use of ocean carbon sequestration to reduce greenhouse gas concentrations in the atmosphere. The project will continue through March 31, 2002, with a field experiment to take place in the summer of 2001 off the Kona Coast of Hawaii. At GHGT-4 in Interlaken, we presented a paper detailing our plans. The purpose of this paper is to present an update on our progress to date and our plans to complete the project. The co-authors of this paper are members of the project’s Technical Committee, which has been formed to supervise the technical aspects and execution of this project.

Evaluation of Tracers for Use in the International Field Experiment on CO2 Ocean Sequestration
An international field experiment is scheduled to take place off of the west coast of the big island of Hawaii during the second half of 2001 (Adams, et al., 1999; Herzog, et al., 2000). Scientists representing some dozen institutions in five countries on four continents are expected to participate. The experiment will involve several sub-experiments in which CO2 will be released at a depth of ...
متن کاملLimestone-particle-stabilized macroemulsion of liquid and supercritical carbon dioxide in water for ocean sequestration.
When liquid or supercritical CO2 is mixed with an aqueous slurry of finely pulverized (1-20 microm) limestone (CaCO3) in a high-pressure reactor, a macroemulsion is formed consisting of droplets of CO2 coated with a sheath of CaCO3 particles dispersed in water. The coated droplets are called globules. Depending on the globule diameter and the CaCO3 sheath thickness, the globules sink to the bot...
متن کاملExperiments to Investigate Co2 Ocean Sequestration
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...
متن کاملDecarbonization and Sequestration for Mitigating Global Warming
Mitigating the global warming greenhouse effect while maintaining a fossil fuel economy, requires improving efficiency of utilization of fossil fuels, use of high hydrogen content fossil fuels, decarbonization of fossil fuels, and sequestering of carbon and CO2 applied to all the sectors of the economy, electric power generation, transportation, and industrial, and domestic power and heat gener...
متن کاملSensitivity of sequestration efficiency to mixing processes in the global ocean
A number of large-scale sequestration strategies have been considered to help mitigate rising levels of atmospheric carbon dioxide (CO2). Here, we use an ocean general circulation model (OGCM) to evaluate the efficiency of one such strategy currently receiving much attention, the direct injection of liquid CO2 into selected regions of the abyssal ocean. We find that currents typically transport...
