Move over, corn and soybeans: The next biofuel source could be giant sea kelp
Giant kelp, the world’s largest species of marine algae, is an attractive source for making biofuels. In a recent study, we tested a novel strategy for growing kelp that could make it possible to produce it continuously on a large scale. The key idea is moving kelp stocks daily up to near-surface waters for sunlight and down to darker waters for nutrients.
