Adaro Develop Fuel "Jatropha"

PT Adaro Energy Tbk develop the use of biodiesel fuel derived from Jatropha for moving conveyances their coal products in South Kalimantan.
The project which started in early 2010 was beginning to show results even though the project has just reached a year old. "This is already showing results, but still in the pilot project level and it can not be regarded as a valuable commercial projects," said Manager of Corporate Reporting Adaro, Perry B Slangor in Jakarta on Monday (5/30/2011).

The development of this project conducted in cooperation with Komatsu Ltd. Adaro and PT United Tractors Tbk. The project started on March 31, 2010.
Bio Diesel from Jatropha curcas will be used for a fuel dump trucks (class mining truck manufactured 90-ton Komatsu). If the project is successful, then Adaro hope will gain a new source of renewable fuels, and leave the dependence on fossil fuels.
"We're going to enter the bio-diesel is gradually on the dump truck tank is gradually mixed with fossil fuels. However, over time will further increase the composition of bio-diesel," said Perry.

Bio diesel produced in this project is 1-2 tons per day. "We are planting jatropha curcas adjacent to the mine area. We select suitable jatropha because of the distance in the region that are not fertile as mine," said Perry in a journey towards the town of Tanjung, South Kalimantan, one of the largest mining areas managed by Adaro.

PT Adaro Energy require mine reclamation land or unproductive land to plant jatropha trees. These plants are needed as raw materials for manufacture of vegetable oil fuel, which is used to drive the vehicle at a coal mine operations that they manage in the Cape region, Tabalong regency, South Kalimantan.

Director of Marketing and Support, Komatsu Limited (manufacturer of heavy equipment up hope Japan) in Indonesia, Chikaya Sakai, express it in Tanjung, Tabalong, Tuesday (05/31/2011). He explained about the development projects jatropha curcas Fuel Development in the area coal mines managed by PT Adaro Indonesia, a subsidiary of PT Adaro Energy.
According to Sakai, until recently, the area planted new range of existing 50 hectares. Though the land needs to reach 4,000 acres. "The thing is, we can only develop their own land for planting distance on a land mine reclamation area of 400 per year. So much land needs," he said.
Planting 4,000 hectares of land was needed to achieve the target production of castor oil fuel as much as 8,000 tons per year in 2012.

Algae keeps nosing around clean energy news

It doesn't have the sunny cache of solar or the exotic qualities of wind, tidal and geothermal power. But the rapidity of algae fuel's reported advances are hard to ignore. At least for this former reporter.

In my backyard at the University of California, Merced, researchers received a grant to "perform a comprehensive life cycle analysis study of algae biofuels." The money, a modest $142,747, is part of about $3.5 million issued by the California Energy Commission's Public Interest Energy Research program.

Algae takes a back seat in the grant to other projects that include improving grid reliability, energy efficiency and automobile fuel economy. But, hey, it's algae. Pond scum. This is the stuff that may be grown in wastewater settling ponds, harvested and turned into diesel fuel. Or food additives, you never know.

But the important thing is algae wasn't left out. It's not cold fusion. This stuff shows true promise as an alternative energy source.

CEC Commissioner Jeffrey Byron put it this way in a statement from the agency: "California's strength comes from the ability to invest in energy research across the board."

No kidding. And this pond scum just may keep oil prices from breaking the bank. Cambridge, Mass.-based Joule Unlimited announced that it has created a "cynobacterium" that secrete a product identical to ethanol or diesel fuel, according to Joule biologist Dan Robertson, quoted in dailytech.com.

This breakthrough, the company says, could enable the production of 15,000 gallons of diesel per acre annually. The company says it can do it for $30 a barrel.

That has yet to be proved commercially, of course. But developments are coming hot and heavy across the globe. Biodigest.com rattled off a handful of promising developments in Australia, topping off the list with serious production efforts by Aurora Algae and Algae.Tec.

And Oilgae.com/blog/, an aggregator of stories, lists multiple posts daily. One that caught my eye highlighted a peer review of the draft report "Biofuels and the Environment: First Triennial Report to Congress," scheduled by the U.S. Environmental Protection Agency. The report will give Congress a taste of what's coming.

Expect pond scum to do more than lurk in a puddle on the floor with lobbyists during discussion.

I do like to include practical applications in these rants. Nothing epitomizes that more than the biofuel-powered Bentley Continental Supersports convertible, reportedly capable of more than 200 mph. The vehicle debuted this week at the Geneva Auto Show in Switzerland. Ami Cholia of inhabitat.com writes: "an on-board fuel supply system monitors the content of the fuel tank to make sure that power and torque remain constant regardless of the ratio of petrol to biofuel."

Pretty cool. So it can handle anything you throw at it and still go fast. We put fuel oil in a bug once and it ran. Barely. We had to clean the plugs, but it got us out of a jam.

The Bentley, I assume, would be better.

Biofuels still must prove themselves. Ethanol, even as an additive, has gotten mixed reviews. For instance, the lawnmower mechanic in Old Town Clovis told me if I kept using that "cheap garbage gas" I'd continue to have problems with my mower's carburetor. Her gripe? Ethanol. It gets gummy and nasty if allowed to sit too long. (Hint: use stabilizer.)

UC Merced plans to analyze emerging algae biofuels technology and provide feedback on the rather interesting concept of extracting fuel that doesn't require much land, water or tending. And pond scum grows rapidly in any kind of water. The leftover material, after oil extraction, could be used for fertilizer.

"We will consider the efficient use of residual algae biomass as an energy rich waste stream and new harvesting techniques that could improve the sustainability of the overall process," wrote J. Elliott Campbell and Gerardo Diaz of UC Merced and Joseph M. Norbeck of University of California, Riverside.

As I read over their proposal, I determined that the process of extracting and refining sounds far above my paygrade.

But as I was scanning through one of the many algae related websites, I found this do-it-yourself book: "Making Algae Biodiesel at Home" (Making-Biodiesel-Books.com, $99.99). It says it can, among other things, show the home brewer how to build an 80-gallon algae photobioreactor "for less than $215."

Somehow it doesn't sound as promising as my once prolific beer-brewing efforts in Anchorage before I was married. But who knows? The practice may catch on.

All you need is a biofuel Bentley.

How to Make Biodiesel from Jathropha curcas

Biofuels as an Alternative Replacement Fuel

In general, the term can mean fuel biofuels from vegetable, the most probable development for the substitution or replacement of energy is biodiesel (from Jatropha oil and Palm Oil) as an alternative to diesel and bio ethanol (from cassava) as a substitute for gasoline.

How to Make Biodiesel from Jatropha Fruit (Jathropa curcas)

Jatropha (Jatropha curcas L), which is a bush plant family Euphorbiaceae. Within five months of this drought-resistant plants begin to bear fruit, full productive at the age of five years, and the productive age of 50 years. Many encountered in Indonesia as a hedge plant.

The fruit can not be consumed because it can cause poisoning. People in rural areas often make use of this plant to treat constipation in children under five years old (toddlers) or eliminate dental pain with distance tree sap dripping into a hollow tooth.

From the results of research conducted Dr.Ir.Robert Manurung MEng, a lecturer in the Department of Industrial Chemistry Institute of Technology Bandung (ITB), together with his team (Nagayama and Masanori Kobayashi Eiichi from New Energy and Industrial Technology Development Organization (NEDO-Japan):

"Jatropha oil can replace petroleum diesel to power generators. Because jatropha can be grown in almost all regions in Indonesia, the castor oil really help generate electricity in remote areas, this oil can be produced by the communities that need electricity, "

According Manurung, castor oil-making process is not too complicated and could dilakukanoleh anyone with sophisticated tools, follow these steps:

* Steam the pieces for an hour distance.
* Then, meat was destroyed by machine blender.
* After that, the fruit flesh and seeds that have been destroyed inserted into the forging machine oil.
* With emphasis on the hydraulic jack, the pulp is squeezed to produce oil.

Every 10 pounds of crushed castor seeds will produce 3.5 liter of castor oil as an alternative to diesel. This oil is intangible, such as cooking oil, which is thick, smooth, and the smell was not noticeable.
