XOM’s 2016 10-K says algae-biofuels research remains active—but not with SGI: https://www.sec.gov/Archives/edgar/data/34088/000003408817000017/xom10k2016.htm (page 3) Many governments are providing tax advantages and other subsidies to support alternative energy sources or are mandating the use of specific fuels or technologies. Governments and others are also promoting research into new technologies to reduce the cost and increase the scalability of alternative energy sources. We are conducting our own research both in-house and by working with more than 80 leading universities around the world, including the Massachusetts Institute of Technology, Princeton University, the University of Texas, and Stanford University. Our research projects focus on developing algae-based biofuels, carbon capture and storage, breakthrough energy efficiency processes, advanced energy-saving materials and other technologies.The collaboration with Synthetic Genomics has not been mentioned in any XOM SEC filing since 2011, so it’s presumably dead.
