Our research is currently focusing on seaweed and the provision of scalable nature-based solutions that offer possibilities for Carbon Dioxide Removal (CDR). Seaweeds are excellent biomass producers that have rapid growth rates. The seaweed can be harvested and sequester carbon long term in ocean sediments or in products such as biochar for soil improvement. As it grows in the sunlight zone of the ocean, seaweed fixes carbon through photosynthetic primary production in the same way as trees and plants on land.

Exploring seaweed biochar as a CO2 removal solution
As part of our goal of removing more greenhouse gas from the atmosphere than we emit, DNV is exploring new, scalable CO2 removal solutions. One such solution that is currently being explored is the capture of CO2 in cultivated seaweed and subsequent storage in biochar.
