Solazyme announced today that they have produced the first 100% algae-based renewable diesel to meet the strict American Society for Testing and Materials (ASTM) D-975 specifications.
Called Soladiesel(RD)™, it is the world’s first 100% algal diesel blend to meet these standards.
The company has road-tested Soladiesel(RD)™ in a factory standard 2005 diesel Jeep Liberty with results that indicate identical usability and engine wear to that of petroleum diesel.
Soladiesel(RD)™ has lower particulate emissions than petroleum-based diesel and also meets the ultra low sulfur diesel (ULSD) standards.
OriginOil has been a busy little company.
On the heels of a breakthrough which the company claims will make algae oil farming a true competitor to petroleum, OriginOil has filed two patents that may make the production of fuel products from algae incredibly cheap and easy in the near future.
Across the U.S., researchers, startup companies and investors are exploring the potential of creating large amounts of green, renewable fuel from the humblest of sources: algae.
If you think the energy/food potential for hemp is underutilized, wait’ll you get a gander at algae. This little microorganism really packs a punch.
According to The Book of General Ignorance: Everything You Think You Know is Wrong (2006, Harmony Books) (I highly recommend it, by the way — it’s packed with fascinating information and weird insights), algae breathes out more oxygen than all the world’s land-based plants and trees combined. Certain types of algae also deliver a whopping amount of protein and nutrients per farmed acre (20 times more than soy beans, in the case of spirulina).
Biofuels are increasingly lumped into a single category of environmentally apocalyptic dead-end solutions. As the food vs. fuel debate rages on, it’s no wonder that the general public believes this.
But not all biofuels are created equal, as the chart above illustrates (click the image to see full size). It’s one of the best depictions I’ve seen of how each biofuel feedstock has completely different impacts on overall greenhouse gas emissions, water and pesticide use, and the energy required to produce the fuel.

Those cute little creatures shown in the video are represent what may be the future of carbon sequestration.
CARS is the acronym for Carbon Algae Recycling System, it’s a system under development in Canada to clean up tailing ponds and greenhouse gas emissions left by the Alberta Tar Sands project.
As the video shows, exhaust CO2 is pumped into algae-rich tailing ponds where it’s digested. The plumped-out algae, full of hydrocarbons and heavy metals, are harvested and turned into biofuels.
I happened across this video on algae biofuel today: a company I’ve never heard of, Valcent Products, claims they can grow algae to produce oil yields of 100,000 gallons per acre. That’s the upper range of estimates I’ve seen for algae production—an absolutely phenomenal amount of oil—which Valcent attributes to their ‘high density vertical bioreactor’ system. Check it out (more video after the jump):
It looks like Solazyme will be making algal biodiesel for the US military, after a test-drive demonstrated the fuel’s superior cold-weather properties when compared to commercially-available biodiesel.
Former Director of Central Intelligence and Under-Secretary of the Navy R. James Woolsey tested the fuel himself by driving to the Worldwide Energy Conference & Trade Show in an unmodified 2008 Ford F450 fueled by 100% algal biodiesel.

There’s always a better whey.
A Wisconsin cheese producer, Joe Van Groll of Stratford, Wisconsin, has a way with whey.
For nearly a decade, Van Groll experimented using the waste product of cheese manufacturing, whey permeate, to manufacture ethanol. During the past four years, he’s been doing just that, and believes his process can produce ethanol for less than $1 a gallon.

Would I put you on? It’s true, algae-based biofuels are being produced from CO2 emitted from smokstacks.
It’s happening through a company called GreenFuel, headquartered in Cambridge, Mass.
GreenFuel has been partnering with Arizona Public Service Company to create biofuels from algae grown using carbon dioxide (CO2) emissions from a power plant. The companies successfully grew algae at APS’ Redhawk natural gas power plant in Arizona, and is moving their tests to a coal-fired power plant at Farmington, NM.
According to a release from APS, algae at Redhawk grew at levels 37 times higher than corn and 140 times higher than soybeans, which are now used to create biofuels.
While the first algae-to-biofuels facility went online today, scientists at Argonne National Labs are manipulating the photosynthetic super-organism for another use: creating hydrogen.
Algae grows prolifically in adverse conditions, and can store large amounts of oils or starches useful for making biodiesel or ethanol. But some strains also use an enzyme called hydrogenase to produce small amounts of hydrogen gas. Scientists think this is the organism’s way of getting rid of excess energy under high-light conditions.
