Fly with Biojet Fuel

This won't be here tomorrow, but it looks like it works and they'll keep working on it to make it economical and ready to go during one of the periodic greed-fest, petroleum spikes.

SAO PAULO (Dow Jones)--A leading Brazilian biofuel plant manufacturer, Tecbio, says it is confident that it will soon develop what could be considered the holy grail of airplane travel in a time of towering world oil prices: a technically and even economically viable bio-jet fuel by 2008
"Within a maximum of two years, we will have an answer to this," said Expedito Parente, the president of Tecbio in a phone interview with Dow Jones Newswires.

The company signed a memorandum of understanding with U.S. airplane maker Boeing last month to jointly develop the bio-aviation fuel, said Tecbio.
Under a verbal agreement between Boeing and the U.S. National Aeronautics and Space Administration, the Tecbio fuel may then be sent to NASA for testing and evaluation, added a NASA spokesman on Thursday.

Tecbio says it can't reveal any further details about its product these days due to a confidentiality clause in the agreement. However, the company's new bio-jet fuel may be produced from oils extracted from at least a dozen different plants native to Brazil's north
and northeast region, according to an interview that Francisco Guimaraes, Tecbio's commercial spokesman, gave to local Diario do Nordeste newspaper last month.
Among these plants are different types of palm trees including the babacu palm, the coconut palm, and the macauba palm.

A secret formula for bio-aviation fuel has already existed in Brazil for over two decades.
In 1980, Parente - then a professor at the Federal University of Ceara in the northeastern state of the same name - pioneered Brazil's first biodiesel and biojet fuel experiments.
There was good reason for such experiments back then. Brazil was heavily dependent on imported oil in those years, and its economy was crippled by the oil shock of the 1970s.
Local scientists responded to the energy crisis by designing a range of innovative biofuel solutions to help lighten the country's energy burden, most significantly through the use of
home-grown sugarcane-based ethanol and ethanol technology.

"To produce biodiesel, we tested a wide variety of feedstocks: we used cotton, soy, sunflower, peanut, cow tallow, and fish oil," said Parente, adding that his team also conducted similar experiments from vegetable-based sources to produce biokerosene for aviation use.
At that time, however, the country was ruled by a military dictatorship, and such experiments - which were conducted under the auspices of the country's aerospace agency, or CTA - were kept under wraps as a state secret.

In 1984, at the pinnacle of the program, Brazil launched its first successful and covert flight with biokerosene, in a 600-kilometer journey from the municipality of Sao Jose dos Campos in Sao Paulo state to the country's capital of Brasilia. The plane for the test flight was
manufactured by local company Embraer, now the world's fourth-largest airplane maker.

Despite that technical triumph, however, the government abruptly dismantled the program that same year. "People were really just interested in ethanol back then," remembered
Parente. "The country was drunk on ethanol. And sugar prices were really low then, so millers wanted to divert cane to ethanol. There wasn't much government interest in biodiesel or biokerosene." Times have changed, however, as oil prices have raged over $70 per barrel
in recent months, and doomsday prophets are once again arguing that the twilight of peak oil
is nigh. "It's much more pressing now than it was back then to fill the void that petroleum will leave," said Parente. "Our great challenge is to develop alternative energies - solar, wind, wave, and biofuels."

In 2001, Parente and other investors formed Tecbio - with headquarters in the Ceara state capital of Fortaleza - to capitalize on the world's growing need for renewable energy through the manufacture of state-of-the-art biodiesel plants.
To date, the company - which currently has annual revenues of roughly $15 million from its engineering division - has just built one biodiesel plant, located in the northeastern state of Piaui, for the country's leading biodiesel supplier, Brasil Ecodiesel, the parent company of
Brasil Biodiesel. However, the company is planning to build another 11 plants by the end of
2007, six of them already contracted by Brasil Ecodiesel, said Parente.

In addition, the company is also studying ways of using waste sub-products from biodiesel production in order to yield more energy, a process that could be technically ready within five years time, he added.

Still, Parente never forgot his past experiments with bio-aviation fuel - and when the possibility arose this year to once again carry the idea further - he said he jumped at the chance. "It makes sense now, with oil prices where they are," he said. There are several advantages to using biokerosene in jet planes rather than other biofuels, says Parente.

First, biodiesel is just too viscous a fuel to work properly in jet engines. Meanwhile,
while ethanol can be used in airplanes without any technical problems - Embraer, for example, already manufactures ethanol-fueled airplanes - the biofuel is highly inefficient compared to conventional kerosene.

A jet engine will burn through roughly 2 liters of ethanol for every 1 liter of aviation fuel.
Biokerosene, on the other hand, is ideal for use in jets, since it is consumed at a ratio that is equivalent to normal aviation fuel, said Parente.
And, of course, it is made from renewable sources.

Whether or not Tecbio's bio-jet fuel takes off in the future, however, Parente points out that the sector has an incredible range of possibilities just starting with biodiesel.
"There are about 90 species of Amazonian plants that can be used to produce oils that can be used as biodiesel feedstocks," he said. "Our vision is that parts of the Amazon could be reforested with these plants to produce these feedstocks, without a loss to the region's biodiversity," he said.

No one at Boeing was available on Thursday to comment. However, NASA is already actively pursuing research in alternative jet fuels - through its Subsonic Fixed Wing project - "to both reduce emissions and increase the nation's energy independence," said a NASA spokesman in
an email.

Brazil is one of the world's leading biofuel producers, as well as the world's top ethanol exporter.
