Artificial Upwelling for Carbon Dioxide Removal

Uses infinite ocean wave energy to grow phytoplankton, that like trees absorb carbon dioxide, but much faster and feed fish in the sea. When these plankton die they sink to the mid & deep ocean where the carbon is stored for centuries. We are the “First Mover” in Ocean Upwelling for CO2 Removal.

How pumps work

Deployed far offshore and way from coral reefs.

  1. Upon initial deployment, water in the tube is of mixed nutrient densities that are mostly tied to which stratum of the ocean that part of the tube is in.
  2. As the buoy descends off a wave it causes the lower pump valve to open, infiltrating nutrient-dense deep ocean water into the bottom. As the buoy moves up the next wave, the valve closes which forces water up the tube.
  3. Soon after deployment, the nutrient-dense water has traveled to the top of the tube where it is released, supporting growth of phytoplankton.

Pump Design

Designed with Rapid Scale-up in Mind

Since 2005 we’ve tested and refined our technology. We’ve partnered with major research institutions to test the pumps in labs and the open ocean.

Maintenance Management

Artificial Upwelling Pumps have a design life of 80+ years if properly maintained. Much of the routine maintenance can be accomplished in situ – removing biofouling from the buoy, swap-out of on-buoy electronics, solar/battery maintenance, etc. This is achieved by snagging the buoy recovery line and lifting the buoy onto the workboat aft deck, then performing the necessary procedures.

If the inspection determines fabric tube replacement is required, the valve/bottom-weight recovery line is winched in which lifts the bottom weight to the surface, emptying water from the tube. The tube is re-spooled and a new tube is fitted to the top valve outlet and the valve/ bottom-weight, then deployment procedures are followed.

AUP’s requiring more extensive repair or refurbishment are brought back to shore and recycled or the components repaired and re-used.

End of Life

At end of life, the Pumps are removed and brought onshore for recycling or disposal. Our pricing schedule includes an allowance to cover these costs.
