Exaquest Carbon
Exaquest Carbon has been awarded a research grant to ​evaluate the environmental impact of the BioSink project.
Open Source
Carbon Dioxide Removal
for Climate Justice!
Exaquest Carbon is a 501(c)(3) non-profit research organization ​developing open-source carbon dioxide removal (CDR) methods.
Our mission is to develop scalable CDR methods that can be ​implemented by small and large operators worldwide.
See our blog for news and details: ​www.biosink.org
Phase 1 Completed : Bio-Dry
We have completed development of our first project for Dry Storage of ​Biomass for durable carbon sequestration. The final report is linked ​here.
This method is now being scaled by Tau Carbon. For details, please visit ​www.taucarbon.com.
Phase 2 Started : BioSink
BioSink, an all-natural method of CDR, involves collecting dead, waste ​wood; and bringing it to a depth of 800 ft in the ocean. In minutes, the ​hydrostatic pressure at that depth causes wood to be waterlogged and ​sink naturally, more than ten thousand feet, to the seafloor below.
Once at the seafloor, carbon that was captured by the wood stays out of ​contact with the atmosphere for over 1000 years. The abyssal plains of ​the ocean floor are 4000 meters deep, remote from human activity, far ​larger, and far more barren of life than the Sahara desert.
We will use conventional transport infrastructure to implement this low-​tech, safe and legal process. The re-emission of CO2 in this method is ​calculated to be only 2.3%.
In addition, we will develop a platform for training ocean fishing operators ​worldwide to sink locally sourced waste forest and farm biomass. ​Participation by small and large operators will increase the scale of our ​CDR effort to gigatons of CO2 annually, and provide a sustainable ​alternative income to fishing.
BioSink Process
Near the surface,sea plants and animals are plentiful
At 800 ft depth, wood becomes waterlogged and sinks
At 1000 ft depth, the ocean is dark,
with few animals and no plants
3000 ft deep, zooplankton hide
from predators during daytime
6000 ft: some whales dive this deep, for minutes
At 12000 ft, Titanic haunts the barren seafloor.
