 What if space held the key to producing alternative energy crops on Earth? That’s what researchers are hoping to find in a new experiment on the International Space Station.

The experiment, National Lab Pathfinder-Cells 3, is aimed at learning whether microgravity can help jatropha curcas plant cells grow faster to produce biofuel, or renewable fuel derived from biological matter. Jatropha is known to produce high quality oil that can be converted into an alternative energy fuel, or biofuel(biodiesel).

By studying the effects of microgravity on jatropha cells, researchers hope to accelerate the cultivation of the plant for commercial use by improving characteristics such as cell structure, growth and development. This is the first study to assess the effects of microgravity on cells of a biofuel plant.

“As the search for alternate energy sources has become a top priority, the results from this study could add value for commercialization of a new product,” said Wagner Vendrame, principal investigator for the experiment at the University of Florida in Homestead. “Our goal is to verify if microgravity will induce any significant changes in the cells that could affect plant growth and development back on Earth.”

Launched on space shuttle Endeavour’s STS-130 mission in February, cell cultures of jatropha were sent to the space station in special flasks containing nutrients and vitamins. The cells will be exposed to microgravity until they return to Earth aboard space shuttle Discovery’s STS-131 mission targeted for April.

For comparison studies of how fast the cultures grow, a replicated set of samples are being maintained at the University of Florida’s Tropical Research and Education Center in Homestead.

“Watching the space shuttle go up carrying a little piece of my work is an indescribable experience,” said Vendrame. “Knowing that my experiment could contribute to creating a sustainable means for biofuel production on Earth, and therefore making this a better world adds special value to the work.”   by Lori Meggs, AI Signal Research, Inc.

In past days the envelopes with the technical offer of the Official Plan of Renewable Energies (GENREN) bid were opened. The proposing companies are now waiting for the economic offer envelopes.

he Argentine government announced the results of the 1,015 megawatt (MW) renewable energies tender proposed last May. The total offers reached 1,461 MW, a 46% oversubscription. The offers were broken down by technology: 1,203 for wind power; 155.4 MW from biofuels; 54.1 MW from biomass; 14 MW from biogas; 22.5 MW from photovoltaic solar energy; and 12.7 MW from small hydro projects.

The opening of the sealed envelopes was done at a ceremony at the presidential mansion known as la Casa Rosada, which included words from Argentine President Cristina Fernandez de Kirchner as well as from the Federal Planning Minister, Julio de Vido.

According to a recent study by the Argentine Renewable Energy Chamber (CADER), nearly 70% of Argentina’s territory is covered with winds whose annual average speed, measured at 50 meters above ground level, surpasses 6 m/s. In Central and Southern Patagonia the speeds can reach on average 9 m/s and up to 12 m/s. Most areas in the vast Patagonia region experience annual average capacity factors above 45%. The provinces of Córdoba, part of San Luis, La Pampa, San Juan, La Rioja and the central and southwestern regions of the province of Buenos Aires yield capacity factors between 35% and 40%.

But despite such massive potential, the 30 MW of wind generation that has been installed to date comes mainly from projects completed between the mid-1990s and early 2000s that were developed by small cooperatives in the Patagonian region.

The tender had been launched by the government last May to assist in the requirements under Renewable Energies Law 26.190 from 2006 that requires that by the year 2016, fully 8% of the country’s energy matrix must be derived from renewable sources. Once all offers have been reviewed, the government must evaluate each one objectively – prices offered and the companies’ technical and financial capacity, among others. According to calculations by the Argentine Renewable Energies Chamber, if all 1,462 MW are accepted it will result in investments in excess of US$2 billion and the creation of approximately 1000 new jobs.

After the public announcement, the President of the chamber, Carlos St. James, exchanged thoughts about the next steps with President Fernandez, expressing optimism about the future of the industry. “These offers, considering the quality and prestige of the multinational companies making them, leaves no doubt that Argentina is on its way to developing a full-fledged renewable energies industry. This is a clear demonstration of what can be achieved when a fluid communication is established between the public and private sectors.”

As the chamber had indicated in its recent State of the Argentine Wind Industry study published last May, Argentina has unequaled potential to develop wind energy, as seen by the dominance of wind projects in the tender totaling 1,203 MW, more than 80% of the total offerings. According to Mauro Soares, President of the Wind Energy Committee of the Chamber, “This tender generated unparalleled activity and interest from our sector; the number of proposals focused on wind was very gratifying. Now we will finally see this energy become part of our country’s energy matrix. We welcome this launch of the industry in Argentina, and I congratulate all those that worked towards making it possible.” Also, Sebastian Kind, co-author of the study and board member of the chamber, stated, “Today we saw a high degree of confidence of the sector’s potential; the 1461 MW offered represent solid foundations for a prosperous renewable industry. Argentina has a unique opportunity to generate new skills and develop technology while providing clean and competitive energy for our future.”

According to a recent study published by New Energy Finance, based in London, the global renewable energies industry invested US$155 billion in 2008, with a compound annual growth rate of 45%. Latin America captured US$12 billion of this total, but it is growing at a CAGR of 145%.

The Argentine Renewable Energies Chamber (Cámara Argentina de Energías Renovables, or CADER) is a non-profit industry trade association dedicated to the sustainable development of renewable energies in Argentina. It seeks to play a vital role in the establishment of a solid and vibrant industry, one which is respected globally for its standards and practices.

The Chamber counts among its members companies that believe these principles and work towards developing the local solar, wind and biomass sectors. Its great diversity in members creates one of the Chamber’s greatest strengths, since it is the only organization that represents the entire spectrum of this nascent industry’s value chain.

In past days the envelopes with the technical offer of the Official Plan of Renewable Energies (GENREN) bid were opened. The proposing companies are now waiting for the economic offer envelopes, which will be handed once the technical analysis is concluded. The complete list of proposing companies follows.

1. Emgasud Renovables: 4 wind farms (3 of 50 MW and one of 30 MW, two in Madryn and one in Rawson)

2. Patagonia Wind Energy: one 50 MW wind park, in Madryn.

3. Energías Sustentables SA: one 20 MW wind farm, in West Madryn.

4. International New Energy: one 50 MW wind park, in North Madryn.

5. Sogesic SA: 2 wind parks, of 50 MW, in Tres picos.

6. Unitec Energy – San Jose Argentina – INVAP (UTE): 2 wind parks, of 50 MW.

7. Isolux Ingenieria – Gas y Petróleo de Neuquén – Ingenieria Sima SA, (UTE): one 50 MW wind park.

8. Isolux Ingenieria: 4 wind parks of 50 MW in Loma Blanca 1.2.3 and 4.

9. Impsa Wind SA: 10 wind parks. Kaluel Kayke I (50MW), II (25MW), Malaspina I (50 MW), II (30MW), Condor Cliff La Barrancosa (50MW), Piedra Buena I (50MW), II (30MW), Las Heras (50 MW), Tornquist (50MW).

10. Pan American Fueguinas SA: 28 MW wind park in Cerro Dragon.

Patagonia in Argentina has some of the best conditions in the world for wind power generation. Not only are the winds strong in Patagonia, but they are also fierce in the south of Buenos Aires province and interior provinces such as Córdoba. Blessed with such potential, Argentina should be a world leader in wind energy.

“The big race is for the corn” said Julio Ferrarotti.

Throughout the world, researchers are seeking plants better adapted to stress. In the Biotech Forum, which will take place in Rosario on June 18 and 19, sponsored by Infocampo, will be presented the degree of progress that there is for the crops to have better performance in less favorable situations.

“All lines of work related to heat stress, drought, cold, floods, are
related to climate change, and in this sense what we are going to hear in
the forum concerns to the progress in developed countries, in emerging ones, and, of course, in Argentina.” says Julio Ferrarotti, organizer with Pablo Adreani (Agripac).

- What is being done in the world in terms of adaptation to drought?

-At both private and public levels, there is much activity in the world in
this issue. In the United States, the European Union, Japan, Australia,
Brazil and Argentina there is aimed research. In our country, the station
Obispo Colombres, in Tucumán, has an event for soybean that is at
deregulation in the National Commission of Biotechnology, and Bioceres is
also working with the Universidad Nacional del Litoral.

- What mechanisms are involved in the adaptation of crops to water stress situations?

There are several strategies that can be amplified genes or combined genes
of amplified expression, which regulate defense mechanisms against drought, or it may be the introduction of inedit mechanisms, present in xerófitas species (adapted to dry climates) that are not present in cultivated
species. Mechanisms are linked to stomatal closure, osmotic regulation, cell
tolerance to plasmólisis, etcetera.

In legume we are working on the efficiency of biological nitrogen fixation,
as it has been seen that a plant in a better nutritional status supports
stress better. Ultimately, however, all lines are aimed at improving
efficiency in water use, especially in a scene where the drought seems to be
more frequent.

- What degree of progress is there?

Already, there are different announcements. In the United States have been
shown plants to drought conditions compared to normal plants, and the
positive effects are able to be seen of these transformed plants. Also, the
Biotechnology Institute of Rosario is working on the issue of water shortage
and the photos I saw about the experiments are more than auspicious.

- What are the crops that are of most interest and when they could be released for production?

-The great race is in the corn, which is a crop with high sensitivity to
drought. However, soy is being worked in this direction. The “when” is most
difficult to know because it depends on the regulatory processes.

-What would have happened in this campaign of 2008/09 if farmers were able to use crops better adapted to dry conditions?

-We would have had a lot less losses in performance. Perhaps much of the
production could have been saved.
