Summary

CREW removes carbon dioxide from the atmosphere by deploying fine-grained natural minerals like calcium carbonate in wastewater treatment systems. The deployment location for this project includes wastewater facilities operated by the Hampton Roads Sanitation District (“HRSD”), a political subdivision of the Commonwealth of Virginia, serving the Hampton Roads region.

How carbon is being removed

Marine carbon dioxide removal (mCDR) leverages the ocean's natural capacity to absorb and store carbon for thousands of years. These pathways use the biogeochemical and physical properties of the ocean and other bodies of water to capture carbon dioxide from the atmosphere or to permanently store carbon already contained within them. Approaches to mCDR include Ocean Alkalinity Enhancement and Direct Ocean Capture and Storage.
