Greenhouse Gas Mitigation technology

Core technology greenhouse gas mitigation

Earth Ocean & Space Pty Ltd hold patents for a Greenhouse gas mitigation technology as described below.

 

The Ocean Nourishment organic carbon cycle in the ocean shows a large amount of carbon limited by the amount of nutrients in the ocean. The Ocean Nourishment process mimics nature by providing supplimentary nutrients to increase the size of the organic carbon cycle. Nourishment for the ocean is obtained from the atmosphere using natural gas as fuel stock by a process that releases little carbon dioxide.

 

The nourishment is delivered at the edge of the continent shelf by pipeline and then swept over the deep ocean by prevailing currents. Enhanced photosynthesis consumes from each plant, 10 million tons of carbon dioxide per year, generating a valuable stream of carbon credits. In addition, increased fish stocks help restore the health of the oceans.

 

Ocean Nourishment is a new concept that is needed to manage the climate and increase the supply of economical protein. It was discussed in Jones and Young (1997) Engineering a large sustainable world fishery. Environmental Conservation, 24, 99-104.



The Ocean Nourishment process is predicated on a number of observations of the ocean organic carbon cycle.

  1. Ocean Nourishment is to be carried out in those areas short of macronutrients but with excess micronutrients. (In the longer term it is proposed to supply all the nutrients, both macro and micro nutrients making the concept site independent). This will change the ecology in regions nourished. It will no longer be oligotrophic.
  2. On time scales of years and ocean space scales, export equals new primary production. [Losses of nutrient in secondary production is negligible. The fraction of primary production exported determines the time for total export, not the amount.]
  3. For new primary production, carbon molecules to nitrogen molecules on the average are in the Redfield ratio and that is near 7:1 or 106/16.
  4. Of carbon exported to depths greater than the top of the permanent thermocline, only a small fraction reaches the sea floor (in deep water) and the rest eventually returns to the surface ocean after hundreds to thousands of years.
  5. When the carbon exported by Ocean Nourishment returns to the surface, most of the added nitrogen is again available to support photosynthesis and so repeats the cycle.
  6. In the absence of additional silica, diatoms are not expected to dominate the assemblage of phytoplankton in the enriched water. The Redfield ratio needs to be replaced when estimating carbon export for phytoplankton incorporating calcium carbonate.
  7. Some additional GHG is produced in the Ocean Nourishment process and needs to be considered in calculating the effective storage of greenhouse gas.
  8. Some of the new primary production passes thru the food chain. Marine products taken from the sea and consumed on land are a loss to the ocean carbon store. Fish are about 11% carbon (see Jones, 2004 on page 535). The wild fish catch is about 100Mt/yr. CO2 loss from the ocean store by fishing is 11x44/12 = 40 Mt/yr. This is small compared with a global new primary production of 10,000*44/12 MtCO2 per year. Thus leakage due to fish harvest can be a small fraction of the carbon stored by macronutrient addition. The other parts of the food chain that are not harvested are eventually exported from the surface ocean into the organic carbon cycle.
