Summary

Planetary Technologies add alkaline compounds to seawater to enhance the natural ability of seawater to absorb atmospheric carbon dioxide, storing the carbon in dissolved carbon-containing ions in the oceans for 10,000-100,000 years.

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.

Monitoring locations

Ongoing monitoring is required in the outfall prior to discharge and at the edge of the mixing zone. These measurements are used for ensuring compliance with regulatory limits and Planetary’s self-imposed stop-trigger limits in their adaptive management plan. Stop-triggers include thresholds for avoiding alkalinity losses through secondary precipitation and biotic calcification, as well as environmental safety thresholds. See the Operations Report for more detail.

Reversal risk

The risk of reversal for this project has been assessed as Very low. This means that 2% of credits issued for this project are allocated to Planetary's buffer pool.

To date, this project has contributed 66.466 credits to the buffer pool which holds a total of 66.466 credits.

Planetary has no reversals to date.
