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). http://www.wolfhilbertz.com/downloads/1979/hilbertz_IEEE_1979.pdf
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 produce 90+% pure biomethane, 90+% pure CO2 to sequester, and the nutrien
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
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. D
