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.
