Researchers have made a breakthrough in the development of "green gasoline," a liquid identical to standard gasoline in energy contant yet created from sustainable biomass sources like switchgrass and poplar trees. The discovery could transform the renewable fuel economy by eliminating the need to grow corn for ethanol and rescue America from importing expensive and dwindling foreign oil supplies.

The latest pathways to produce green gasoline, green diesel and green jet fuel are found in a report sponsored by NSF, the Department of Energy and the American Chemical Society entitled "Breaking the Chemical and Engineering Barriers to Lignocellulosic Biofuels: Next Generation Hydrocarbon Biorefineries" released April 1 (http://www.ecs.umass.edu/biofuels/). In the report, Huber and a host of leaders from academia, industry and government present a plan for making green gasoline a practical solution for the impending fuel crisis.

As ethanol and biodiesel help to allay some of the strain caused by increasing core commodity prices and imported oil nearing $140 a barrel, research conducted on biomass feedstocks such as algae continues to gain traction as a viable means for “closing the loop” on energy sustainability. One company in particular is striving to meet this goal.

San Diego, Calif.-based Sapphire Energy was founded in 2006 on the basis of this principle philosophy when it debuted its “green crude”, a gasoline equivalent refined from algae that comes in light and heavy fractions; the light being gasoline and a heavy being kero-disel (or jet aircraft fuel). Although it won’t divulge its production process specifically, according to Sapphire Chief Executive Officer Jason Pyle, the company is producing 91 octane gasoline built on the platform that uses nothing more than sunlight, carbon dioxide and complex photosynthetic microorganisms.

The Savannah Research National Laboratory have created a multipurpose new material, composed of tiny glass bubbles, which behaves both like a fluid and a solid. Researchers at Savannah Research National Laboratory (SRNL) preface the news release for their impactful glass microsphere breakthrough, with a riddle. "What looks like a fertilized egg, flows like water, gets stuffed with catalysts and exotic nanostructures and may have the potential of making the current retail gasoline infrastructure compatible with hydrogen-based vehicles of the future – not to mention also contributing to arenas such as nuclear proliferation and global warming?"The spheres measure a scant 2-100 microns in diameter. This puts them at smaller than the width of a human hair. The key asset of the spheres are tiny pores which adorn their surface. These pores can be controlled by processing to measure from 100 to 3,000 Angstroms and they form full tunnels between the inner and outer wall, through which chemicals of controlled sizes can pass.A major application of the new material is gas streaming filtering. By adjusting the porosity, the material will act as a filter, absorbing one type of gas and letting the others pass.

Most promising yet, the microballoons can have their mechanical properties tweaked to act like a fluid, including flowing along pipes. This means that current gas distribution infrastructures could be modified to transport solid hydrogen, with little change. This in turn would amount in savings of money and effort spent. The hardy little microballoons are also easily recycled and reused, thanks to their strength. Toyota is sponsoring the SRNL to bring the technology to market to help it with its hydrogen vehicles.

Diesels Come Clean

by Matt Vella

In Europe gas costs more than $5 a gallon. In the U.S., it's under $3. In Europe, diesel-powered cars and trucks account for 50% of all auto sales. In the U.S., they are less than 4%. What do the Europeans know that Americans don't?

They know that diesels provide superior fuel-economy without sacrificing performance. The main concern for most Americans is that the hangover from the smoky, smelly diesels of the 1970s remains fresh in many minds. But changes in the supply of diesel fuel, emerging cleaner-burning technologies, and growing consumer concern over the environment and fuel economy in particular are creating new opportunities for automakers willing to dabble in diesel, says this article
