Still trying to find information out there about the cost of producing fuel from algae. This section from the Wikipedia article on algae fuel doesn’t say very much, really…
As of 2008, such fuels remain too expensive to replace other commercially available fuels, with the cost of various algae species typically between US$5–10 per kilogram.[citation needed] But several companies and government agencies are funding efforts to reduce capital and operating costs and make algae oil production commercially viable
