“I’ve heard a lot about biofuel for aviation tests, but they always sounded suspiciously like airline ‘greenwashing’ PR to me. Richard Branson’s $3 billion bet on an aviation biofuel company went bankrupt. Successful tests turned out to be only fractionally biofuel. Journalists joked about the smell of french fries filling the air. Is biofuel for aviation anything more than good promotion? I posed this question to Steve Verhes, Executive Director of Cascadia Carbon Institute, a Washington state biofuel expert and advocate. Steve’s answer: It’s complicated.
First, there is the food-to-fuel issue – a very real concern, especially with food price increases accelerating this year. But the aviation standards group in charge of the approval took care of that, mandating that aerospace biofuels be derived only from inedible plants.”
