Tim Zenk, VP Corporate Affairs at Sapphire Energy said that sapphires process uses 1.8 kilograms of CO2 for producing 1 kilogram of algae biomass, 50 percent of that algal biomass is oil, so the production of 1 gallon of oil consumes 13 to 14 kilograms of the greenhouse gas.
Although the company uses energy to transport CO2 and water to its algae-production facilities in the New Mexico desert and to transport fuels they produce Zenk said, Sapphire's lifecycle emissions are two-thirds to three-quarters less than those of producing standard diesel.
Raytheon Co., National Energy Technology Laboratory, and other companies are also looking into the reuse of CO2 emissions for algae production.
