After four test flights by four major airlines – carrying engines of the four major manufacturers – the facts are clear to Bill Glover, Boeing’s commercial planes’ managing director of environmental strategy. ‘We haven proven the technical viability of biofuels as a “drop-in” for the traditional Jet-A fuel without any modification to engines or airframe,’ he says. ‘As tests have shown that the biofuels even have a higher energy content and emit, for example, less sulphur, we consider the outcome as a performance breakthrough for the whole industry.
Sustainable biofuels technically near take-off
Boeing says it has proven the ‘technical viability’ of biofuels for use in commercial aircraft. Now the company wants to ‘accelerate’ the process of making biofuels available on a commercial scale.
