Like the rest of nature that evolves remarkably to stresses in the environment, people will be able to adapt to high gas prices. Really. In many parts of Europe, people are paying upwards of $7 - $8/gallon of gas.

Things will change here in the USA. These changes will sometimes more difficult for some than others. More of us are already using public transportation, riding bikes — even moving closer to where we work or pressuring employers to offer flextime (to avoid rush hours) or telecommuting from home. In part thanks to the mushrooming energy costs, how much of business was done in the period of relatively inexpensive oil and other fossil fuels will morph into a new model of business model where energy costs are front and center.

Another trend: the explosion of people starting their own green business as an ecopreneur, operating their business without destroying the planet or exploiting people. Energy conservation and efficiency are often the very DNA of these enterprises. Eventually, the politicians in Washington DC might realize that opening up ANWR merely delays the reality that we need to cut our addiction to oil, for climate’s sake. We need to get back to 350 parts per million of carbon dioxide to maintain some degree of climate stability. Burning more oil, coal or natural gas is not the way.

Most railroads have shown a reluctance to use a biodiesel blend in their locomotives, but the Eastern Washington Gateway Railroad has decided to test the concept this summer.

The first biodiesel blend train pulled out of Creston last week, hauling 52 cars of wheat and 500 gallons of biodiesel in the locomotives saddlebag tanks.  Officials are using a 25 percent blend of biodiesel in the tests.

The fuel is made by Columbia Bioenergy, located in Creston, which uses canola oil, restaurant grease, soy and other crops as feedstock.

Lack of warranty support for biodiesel has been a major stumbling block for new diesel owners who want to start using the fuel. But three long-awaited ASTM specifications could help change that.

Automakers and engine manufacturers have been requesting a finished blend specification for B20 biodiesel blends for several years, with some citing the need for that spec as the single greatest hurdle preventing their full-scale acceptance of B20 use in their diesel vehicles.

On June 19th, after more than five years of research and discussion, the American Society for Testing and Materials (ASTM) finally approved the following specifications for biodiesel fuel:

• Changes to the existing B100 biodiesel blend stock specification (ASTM D6751)
• Finished specifications to include up to 5% biodiesel (B5) in the conventional petrodiesel specification (ASTM D975)
• A new specification for blends of between 6 percent biodiesel (B6) to 20 percent biodiesel (B20) for on and off road diesel.

If that’s gibberish to you, here’s the take home message: the new specification for B6-B20 biodiesel blends could prompt more automakers to fully support B20 in their new cars and trucks.

Around the World in 60 Days

The sleek tri-hull Earthrace eco-boat, has beaten the world speed record for a powerboat to circumnavigate the globe.  The biodiesel powered craft traveled 24,000 nautical miles in 60 days, 23 hours and 49 minutes, finishing its journey by crossing the finish line in Sagunto, Spain.

That beat a record set in 1998 by the British boat, Cable and wireless Adventurer.

Revetec, a little known company from the Gold Coast region of Australia, may be on to something huge: they’ve created an engine that is 50% smaller, 50% lighter, has 50% lower emissions and is cheaper to manufacture than a conventional internal combustion engine of the same horsepower. Oh yeah, did I mention that it doubles the fuel economy too.

What that means is a car like the 2007 Toyota Yaris, which is rated at 40 mpg on the highway, would get 80 mpg with a Revetec engine.

This isn’t some hoax… They have a prototype which has been attached to an actual vehicle and independently tested to substantiate their claims.

As if there isn’t enough bio-diesel controversy over the food for fuel debate now we have a little skirmish arising here in San Francisco. When we walk by any San Francisco restaurant (particularly the ones that have that delish yet oh so bad for you fried cuisine) we can smell where this fuss originated – the fryers. Yes, it’s that oh so wonderful french fry grease that companies like Blue Sky Bio-fuels and Got Grease work with to create biofuel. To us this method makes much more sense to reuse old oil and grease than to the create fuel directly from real food.

In this case the grease skirmish remains between the City of San Francisco and the private sector. Both Got Grease and Blue Sky pick up grease (usually for free) from small restaurants, but now the City jumped into the fryer and collects it as well. The fact that the City collects the oil isn’t a problem but the fact that the City has been using health inspectors to secure oil from the restaurants smells like burnt oil to us. Apparently a letter from the City exists that says something to the effect of “The City has been so busy collecting restaurant oil that we haven’t had time to write up violations.” Should we call this mess “Greasefellas”?

Sure, it’s easy enough for one person to attempt energy self-sufficiency: put a solar panel on your roof, run your car on biodiesel, and you’re halfway there. But how easy is it for an entire town to become self-sufficient?

That’s the question that Reynolds, Indiana has been trying to answer for the past 3 years. In 2005, Indiana Governor Mitch Daniels declared the town to be BioTown, USA—a model of energy self-sufficiency for the state.

The town was chosen mainly because of its small size (pop. 547), excellent rail and road access, and proximity to organic waste (within 15 miles of more than 150,000 hogs). According to the BioTown website, the finished project will showcase efficient methods of converting biomass into energy, use bioenergy to fuel homes and businesses throughout the town, promote alternative energies across the United States, and show that agricultural energy is safe, reliable, and consistent.

These are certainly some lofty goals for such a tiny town, and progress on the project has been slow. In fact, external signs of energy independence in Reynolds have been few and far between. So where does the project stand now?

Biodiesel lovers of San Francisco, rejoice. Starting next Winter, you might not have as much competition when you scour the back alleys behind Chinese restaurants trying to get your car fuel fix.

That’s because the city has just received a $1 million dollar grant from the California Energy Commission to build San Francisco’s first grease-to-biodiesel production facility.

Instead of using the more popular “yellow grease”—fryer oil— the production facility will make use of “brown grease”, or pan scrapings and oil residue trapped in grease interceptors under a restaurant sink. In the past, brown grease has been discarded at sewage plants. Now San Francisco wants to make use of the more than 2.5 million gallons of the stuff that’s in the city.

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.

There are more than 5,000,000 heavy duty trucks running up and down US highways each day. Every one of those trucks gets an average of 7 mpg, carries upwards of 200-300 gallons of diesel, and spews out potentially harmful emissions.

Like it or not, we depend on them to bring us our food, fuel, and products for everyday living. It’s a connection that most of us often forget about, only remembering it long enough to curse them as they slow us down on the highway.

It’s also an industry that has recently been hit hard by soaring fuel prices, and now, with the average price of diesel in the US at $4.70/gallon and climbing, it’s sure to get worse.

Needless to say, there’s a rising cacophony of voices within the trucking industry clamoring for relief. Most of this noise currently comes in the form of wanting a break in fuel prices, but really that’s just a temporary fix. Any solution with sticking power would have to offer both economic and environmental benefit — you know, win-win.

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.
