LanzaTech exploring lipids production as part of its CO2 to acetic acid plans; pathways to renewable fuels

Green Car Congress

Part of the challenge is locating sufficient quantities of hydrogen to enable large scale use of the CO 2 in waste gases. Lipids, in turn, are a proven pathway to jet, diesel and gasoline. LanzaTech envisions using partner technology to convert the acetic acid to lipids—i.e., Earlier post.).

New KOSi method for ultra-deep desulfurization of fuels to ~ 2ppm S

Green Car Congress

Scientists led by a team at Caltech and BP, and in collaboration with researchers at UCLA, ETH Zürich, and China’s Nanjing University, have developed a new method for potentially removing nearly all sulfur compounds (down to ~2 ppm) from gas and diesel fuel. A paper on their work is published in the journal Nature Energy. —Toutov et al.
