Although algae production costs have been coming down, it still remains too expensive for widespread use a feed ingredient for the aquaculture industry, said David Hazlebeck, CEO of Global Algae Innovations.
Algae production costs are currently 10 times too high for a number of reasons, even though costs are coming down as there has been a lot of investment in algae as a biofuel source, he said.
Reducing costs takes innovation, he said.
Reductions in the size of algae inoculation compared with biomass produced, supplying the CO2 used in algae production on site and scalability are all ways to lessen costs, he said.
“We need to be able to get to raceways that are larger than a couple acres,” he said.
His company’s raceway design can be scaled to 100 acres, lessening the amount of controls that need to be applied, as well as labor and construction costs, he said.
