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.
In collaboration with Sintef Ocean, we are setting up a Joint Industry Project to develop solutions for atmospheric greenhouse gas reduction through industrialised offshore, ocean seaweed farming and conversion to climate positive products or solutions. This will include the development of a scalable technology for removal of Carbon Dioxide (CO2), 10% through natural, passive biomass sedimentation during farming and 90% through active deposition, either of fully grown biomass or as biochar. In this value chain the total quantity of atmospheric CO2 removed and permanently stored should be significantly greater than the total quantity of CO2 equivalents emitted to the atmosphere because of the process.
