CCU technologies extract CO2 from concentrated sources or directly from the air, and use it as a raw material. Key technological challenges must be tackled in collecting and purifying CO2 from different sources, in synthesising green-hydrogen, and in converting CO2 to fuels and chemicals.
According to the evidence, the only way to obtain significantly more food and biomass sustainably from the ocean is to harvest seafood from a lower trophic level (lower in the food chain) than we currently harvest.
