The findings of a U.C. San Diego study conclude that marine (saltwater) algae can be just as efficient as freshwater algae in producing biofuels. 

The availability of significant saltwater environments for algae production is obvious. According to a Pacific Northwest National Laboratory’s (PNNL) report, algal fuels grown in saline water from existing aquifers and recycling nutrients would be able to provide up to twice the goal for advanced biofuels set under the Energy Independence and Security Act – roughly 40 billion gallons or 20 percent of annual transportation fuel demand.
