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.
