Shell Oil to grow biofuels from marine algae



Shell Oil formed a joint venture with HR Biopetroleum called Cellana and they plan to produce biofuels from marine algae. Shell, which owns a majority stake in the venture, will start production of a demonstration facility on the Kona coast of Hawai'i Island immediately. The production volume for the facility, which is on a site leased from the Natural Energy Laboratory of Hawaii Authority (NELHA), will be small but the main goal is to research which natural microalgae species produce the highest yields biofuels. Scientists from Hawai'i, Mississippi and Canada are a part of the project that will also explore the potential of algae to capture CO2 from power plants. Graeme Sweeney, Shell Executive Vice President Future Fuels and CO2, says:

Algae have great potential as a sustainable feedstock for production of diesel-type fuels with a very small CO2 footprint. ... This demonstration will be an important test of the technology and, critically, of commercial viability.

Sweeney denies this is all a publicity stunt but they are smart to invest in biofuels from marine algae. The economic viability of the process has to be proven but algae is the most promising non-food source of biofuels, providing 15 times the yield of rape seed, and using the ocean would mean farmland that could grow food would not be a part of the biofuel equation. It's really too bad Shell is a giant oil company. I wonder if anyone will ever take news like this from oil companies seriously?

India to get one million hydrogen driven vehicles by 2020



As yet another country clamoring for the lofty goal of being the alternative/renewable fuel leader, India is making some advances. And the goal seems achievable: one million plus hydrogen-powered vehicles on their roads in the next thirteen years. The hardest part is obviously getting a hydrogen infrastructure in place, but the difficulty of the task doesn't seem to faze them.

Vilas Muttenvar, the New and Renewable Energy Union Minister, says he looks forward to working with the European Union to meet their bio-fuel targets. Those targets involve the use of waste and crop-grown cellulosic materials. While not much emphasis was put on the point, it was at least a little gladdening to see that one of their focuses will be "reducing the environmental impact of bio-fuel usage." After all, if we're just changing the way we ruin the Earth, we haven't really made any progress, have we?

Alternatives to Corn For Bio-Fuel

In spite of the efforts of politicians to tout corn as the answer to the United States' oil import problems, it really isn't a very efficient solution. The amount of energy that can be extracted from corn in the form of ethanol is substantially less than amount energy that must be put in to produce it. A new research report is showing progress in producing biodiesel from algae. Corn can produce the equivelant of 18 gallons of oil per acre per year. Researchers at GreenFuel Technologies in Cambridge, MA is field testing a BioReactor that uses the carbon dioxide in the exhaust flue gas from a power plant to feed the algae. The exhaust gases are passed through a structure where the carbon is absorbed by the algae. The remaining exhaust has the carbon dioxide concentration reduced by 50-80 percent on cloudy/sunny days. They claim that they can produce the equivant of 5,000 to 15,000 gallons of oil per acre per year.

If this can be made to work on a large scale it could make a real dent in crude oil consumption and dramatically reduce emissions from power plants. The fuel produced from the algae could even be used to power the plant itself. If this is combined with more smaller power plants it could also help to support large scale deployments of electric vehicles. Bring on my Tesla and an algae bio-reactor!
