Deep-sea-cold-water and its nutrient and thermal properties can be used in many ways.
The nutrient rich water can be used to support offshore sea-farming and Mari-culture enterprises.

Nutrient rich water can make Marine biomass viable as a source of fuel for large scale energy projects; otherwise it is reported that there is not enough nutrients in the water to support the growth of such large quantities of seaweed.
Since Co2 is absorbed by plankton which then falls to the sea bottom, it might be true that this process is somewhat or occasionally carbon negative, more so than trees and other land crops.

We can either supply you with the water as part of a service or with the equipment as a product.
