The deltas are sinking, due to a variety of causes, incl. O&G exploration and drenching, sea level rise, etc. The biochar, being non-biodegradeable, could be used to build coastal protections. Ideally, it would be first be placed in shallow waters that were above water until recently but became submerged. On top of that, new vegetation can be planted. Moving the biochar around would not be an issue, since transport on water is very energy efficient. Also, the energy for transportation can be derived from pyrolysis heat via heat engines. Harvesting bio-oil and syngas would be excellent, since so much O&G infrastructure is already in place down there. Additional capacities could be added for syngas fermentation (e.g. Coskata process).

I wonder if these kelp clotheslines could be laced in such a way to capture drifting algae as well. If the kelp/algae mixture could be sufficiently dried it would make a great feedstock for fast pyrolysis. Very interesting Albert.

BP should pay for this. And they shall convert their policies from exploiting the earth into serving our old mum gaia.

Blume's idea was to string kelp between disused oil rigs in the Gulf to cleanse the dead zone of those nitrates coming from fertilizer overuse in the Great Plains and Mississippi valley. The kelp could then be harvested for ethanol production. The effect would also be to lower the ocean temperature (kelp forests) and so reduce the hurricane risk for Gulf communities, hence who should pay? The insurance industry. There is no reason why biochar could not be a co-product of this same vision. The kelp forests on "clotheslines" strung between oil rigs are easier to harvest than algae, however. -- Albert Bates, author, The Biochar Solution (New Society 2010, in press).

Many solids are slurried long distances (such as iron sand). There may be issues related to the corrosiveness of an HTC slurry that I am not aware of, but many offshore pipelines are designed for sour service.

The subsea drilling and pipeline network could be enlisted to provide the appropriate pressures & temperatures required for HTC. The export pipelines can then be enlisted to provide shore-based process facilities. There may be other synergies with surplus O&G infrastructure.
