Aviation accounts for about two-to-three percent of the total CO2 emitted through burning fossil fuels, according to the Intergovernmental Panel on Climate Change (IPCC). That’s even with military jets flashing their afterburners and trailing un-enhanced high-altitude contrails. Whether these emissions add to global warming or global cooling seems to be still open to debate. Regardless, almost everyone in the industry feels it is worth eliminating the negative aspects of aircraft emissions. Sea-Tac’s Big Plan Seattle-Tacoma International Airport, Alaska Airlines and Boeing are partnering to power all flights from Sea-Tac with “sustainable aviation biofuel.” The trio has crafted a long-term roadmap to devise an infrastructure “in a cost-effective, efficient manner.” There may be benefits to the local economy, as well as to operational costs for airlines. According to Biomass Magazine, “At the Sea-Tac fuel farm Dec. 16, executives for the port, Alaska Airlines, and Boeing signed a memorandum of understanding (MOU) to launch a $250,000 Biofuel Infrastructure Feasibility Study that will assess …

A broader Overview of Biofuels

Are biofuels truly “green?” Gizmag this morning has an entry on Empa, the Swiss Federal Laboratories for Materials Science and Technology, which has just released a report showing that biofuels may not always be as green as we would like to think. Further, they note that gasoline, including that coming from shale oil sands (as in Keystone XL pipeline oil) may be cleaner than certain crop-derived combustibles. The headlines may stoke controversy, so it’s worthwhile to examine the short-form charts and press release, and compare the impressions gained from a quick glance with those from reading the 113-page study itself. Empa’s press release headline and lead give the impression that things are grim in the green world. The headline “Most biofuels are not ‘green’” is followed by “First tops, then flops.  That is one way of summing up the history of biofuels so far.  A new study led by Empa gives an up-to-date picture of the ecobalance of various biofuels …
