It isn't the existing volume that matters; it is the growth rate. Can it outperform other biological sources? If kelp is a good source then expand its range to beyond the limited habitats in which it exists currently.
They are known for their high growth rate—the genera Macrocystis and Nereocystis can grow as fast as half a metre a day, ultimately reaching 30 to 80 metres (100 to 260 ft).

- nradov 3y agoThere is no practical way to expand the range of kelp. It already grows everywhere it can.
- adolph 3y agoThe range of what is practical changes with how something is valued. If kelp became a higher value crop for biological derived fuel, then some things not practical today may become practical. For example, kelp may not grow in some areas because those areas are especially hospitable to the "Invertebrates that eat kelp include snails and shellfish such as crabs, sea urchins, and abalone." [0] If some of the increased value of kelp were directed towards decreasing those species then it might become practical to grow kelp there. 0. https://earthlife.net/what-eats-kelp/ https://earthlife.net/what-eats-kelp/
