On Friday, Deutsche Lufthansa AG will do something no other airline has ever done. While plenty of aircraft have flown demonstration flights using biofuels, including one in late June involving a Boeing 747-8, no airline has used biofuel during passenger flights. That's because certifying body ASTM International didn't approve biofuel for commercial aviation until July 1st.
Lufthansa will use HRJ (a hydrogenated biofuel that consists of a 50/50 blend of vegetable oil and kerosene) on eight of its daily 28 flights between Hamburg and Frankfurt over the next six months. Lufthansa has dedicated one twin-engined Airbus A321 to the 244-mile route.
