Starting next April, a Lufthansa Airbus A321 aircraft making the daily flight between Hamburg and Frankfurt will be running partially on biofuel. The airline will trial the biofuel blend, made of a 50/50 mixture of kerosene and hydrotreated vegetable oil, in one of the plane’s engines for six months. It’s part of the Lufthansa-led burnFAIR project, which is studying the long term effects of sustainable biofuels on aircraft performance. Although the Brazilian airline TAM performed a test flight of a biofuel-powered Airbus A320
last month, Lufthansa claims to be the first airline to conduct a long-term trial using biofuel during flight operations.
