Andrew, Ocean Macroalgal Afforestation is more of a concept revival with better technology and increased urgency than a new idea. The paper is vetted by co-author David Chynoweth, who has decades of research on seaweed to energy. I confess to alsobeing a co-author. You hit thekey question: At

Methane is flared around the world by the oil industry as a useless by product. Such flaring is generally limited by environmental legislation rather than the existence of viable markets. Even reasonably large methane sources close to population centres are flared off, such as in the Niger

Andrew, Yes.Scaling the floating (or submerged) shipping , storage, and gas-to-liquid conversion facilitiesmay limit how fast we can getOMA toreplace all fossil fuel use and reduce atmospheric CO2 concentrations. Luckily, OMA is unusual in that it is sustainable at the necessary scale to justify

[geo] Ocean based algal growth: rate of CO2 transfer

2013-01-09 Thread Peter Flynn
I am joining this discussion late, so I hope I am not covering ground already discussed. Some years back a graduate student and I looked at a conceptual scheme to grow algae and sink them into the deep ocean, using increased salinity from evaporation as the “pump”. We found that the rate
