Isometric And [C]Worthy Partner On New Marine CO2 Removal Research

Isometric And [C]Worthy Partner On New Marine CO2 Removal Research - Carbon Herald

Isometric, a leading carbon removal standard and registry, has announced a new partnership with [C]Worthy, a non-profit “Focused Research Organization,” to embark on a collaborative project centered around marine CO2 removal.

This research aims to better quantify the uncertainties associated with ocean models that are used to calculate the net effect of marine carbon dioxide removal (mCDR). The collaboration employs advanced models to simulate the dynamic physics, biology, and chemistry of specific oceanic areas.

These models have been rigorously developed and tested by experts from academic and government institutions over many years. Given that the models will play a crucial role in mCDR monitoring, reporting, and verification (MRV), it is imperative to understand and quantify their uncertainties.

The results delivered by Isometric and [C]Worthy will be of great significance for mCDR technologies like Ocean Alkalinity Enhancement (OAE) and Direct Ocean Capture (DOC), which work to eliminate carbon dioxide from the air by creating a shortage in the partial pressure of CO2 in the surface ocean, initiating an equilibrating process that results in atmospheric drawdown. These types of projects face unique MRV challenges related to the ocean.

The difficulties include identifying changes in ocean chemistry against the background noise of the dynamic ocean ecosystem, being capable of measuring over a broader geographical area than planned due to ocean currents for an extended duration as the ocean absorbs carbon over months or years, and proving that a mCDR project resulted in CO2 absorption that would not have happened naturally through ocean/atmospheric carbon exchange.

Models offer a way to address these difficulties, as they are able to replicate the effects of an mCDR intervention and measure the extra removal of atmospheric carbon dioxide that occurs as a result of a project.

Isometric and [C]Worthy will utilize [C]Worthy’s C-Star software, designed to assist in oceanographic and biogeochemical modeling and data integration for mCDR projects, to jointly plan experiments aimed at addressing this lack of knowledge and contributing to the development of reliable future models for marine CO2 removal.
