Is undersea water fully concentrated with CO2 ??? CO2 is absorbed much better in water under pressure Pump it into the deep areas of the ocean and lose it or store it for plant growth later / On Fri, Jun 3, 2011 at 1:10 AM, Stephen Salter s.sal...@ed.ac.uk wrote: ** Mike We could

Michael, DOE has already decided our proposal to demonstrate less than 100 kg of CO2 as hydrate in geotextile containers does not qualify for DE-FOA-441: Small Scale Field Tests of Geologic Reservoir Classes for Geologic Storage. DOE’s version of “small scale” is a minimum of 20,000 tons. DOE

Michael, Ocean Thermal Energy Conversion has yet to be proven economic after many decades of trial. However, the numbers appear reasonable for the production of electricity from biomethane. Ocean Algal Afforestation would produce90+%pure biomethane, 90+% pure CO2 to sequester, and the nutrients

Hi Folks, Thanks for the numbers on Ocean Algal Afforestation and the overall work you and Dr. Stewart have presented. The ocean afforestation approach is an idea which has made a good deal of practical sense to me for sometime. My post concerning the MODEST concept was an attempt to either find

Large scale CO2 hydrate production and deposition may be expedited through the use of a large scale Ocean Thermal Conversion plant positioned over the target sequestration trough. Here is a paper outlining such a system (Fig. 30).

Hi All I used to think that if gas fields had not leaked their natural gas then they should not leak CO2 but I can now see that this argument would be changed by fracking. However if the pressure is high enough the density of CO2 is higher than that of sea water. If you fill a deep sea

But aren¹t deep ocean trenches generally subduction zones, so subject to rather massive earthquakes, as recently occurred off Japan? Mike On 6/2/11 5:42 AM, Stephen Salter s.sal...@ed.ac.uk wrote: Hi All I used to think that if gas fields had not leaked their natural gas then they
