Bagging Algae – Pollutants into Energy

Dean Sigler Sustainable Aviation 1 Comment

For the Fourth Annual Electric Aircraft Symposium on April 23 and 24 in Rohnert Park, California, Dr. Jonathan Trent was an ideal kickoff speaker. His work with NASA Ames Research Center on converting pollutants into algae-based biofuels could have long-term effects on cleaning up our planet’s air and water, and provide byproducts that will help to feed the 900,000,000 who go hungry every day.  As he notes, “Unless we go electric, we must move to low-carbon fuels.” The problem is not a new one.  As musical satirist Tom Lehrer wrote in his 1960’s plea for emissions control, “Pollution, Pollution,” “The breakfast garbage that you throw in to the bay/They drink as lunch in San José.” Dr. Trent, a PhD. in Marine Biology, has a solution called OMEGA, “Offshore Membrane Enclosure for Growing Algae.” Explaining that the wastewater treatment plant on Treasure Island in San Francisco Bay dumps 300,000 gallons of effluent each day, Trent notes that capturing that waste and performing a …

EQ² offers analysis services for clients around the world, their web site introduction citing their goals. “EQ² is a leader in sustainability risk management and environmental inventory systems using accurate environmental measurement and management processes to quantify, benchmark and report an organisation’s risks in regulatory compliance, operational impacts and financial costs.” Among their clients are airlines seeking advice on long-term prospects for alternatives to rapidly-diminishing fossil-derived jet fuels.  Their white paper,  Sustainable Flying: Biofuels as an Economic and Environmental Salve for the Airline Industry, besides having a provocative title, gives some hope for future development of these alternatives. One part of the paper explores the development money put into biofuels and finds that it tracks the rising and falling costs of oil and jet fuel. There’s probably no surprise there, but the charts remind us that we are sometimes reluctant to explore new territory unless some economic imperative drives us. Several aspects of biofuel production have been a source of controversy …
