Marine carbon dioxide removing (mCDR) is getting rising consideration. Typically ignored, the ocean’s huge capability to retailer CO₂ is now seen as an important local weather lever, and one with distinct benefits over land-based carbon removing.
This second article in a three-part collection by ClimeFi and the World Ocean Council explores the rising alternative in ocean-based CDR and the challenges nonetheless to beat.
Ocean-Scale
The oceans already soak up 30% of human CO₂ emissions and retailer over 50 occasions extra carbon than the environment. Not like land-based CDR, ocean-based strategies keep away from battle with agriculture and concrete growth.
From seaweed farming to electrochemical CO₂ removing, many mCDR options can function offshore or close to coastal infrastructure, avoiding the bodily constraints of terrestrial CDR.
Extra Than Carbon: Ecosystem Co-Advantages
Many mCDR approaches additionally ship ecological advantages, equivalent to lowering ocean acidification and bettering habitats for species like corals and shellfish. These impacts help marine biodiversity and assist restore fisheries.
But trade-offs stay. Electrochemical strategies can elevate pH ranges however could introduce hint metals like nickel. Nutrient-based approaches could set off dangerous algal blooms or disrupt marine meals webs. Ongoing analysis is working to attenuate these impacts.
MRV: The Measurement Problem
Strong measurement, reporting, and verification (MRV) stays a…
