Kamojang: Indonesia has launched an ambitious plan to tap the vast power of its volcanoes and become a world leader in geothermal energy, while trimming greenhouse gas emissions.

The sprawling archipelago of 17,000 islands stretching from the Indian to the Pacific Oceans contains hundreds of volcanoes, estimated to hold around 40 percent of the world’s geothermal energy potential.

But so far only a tiny fraction of that potential has been unlocked, so the government is seeking help from private investors, the World Bank and partners like Japan and the United States to exploit the power hidden deep underground.

“The government’s aim to add 4,000 megawatts of geothermal capacity from the existing 1,189 megawatts by 2014 is truly challenging,” Indonesian Geothermal Association chief Surya Darma said.

One of the biggest obstacles is the cost. Indonesia currently relies on dirty coal-fired power plants using locally produced coal. A geothermal plant costs about twice as much, and can take many more years in research and development to get online.

But once established, geothermal plants like the one built in Kamojang, Java, in 1982 can convert the endless free supplies of volcanic heat into electricity with much lower overheads — and less pollution — than coal.

This is the pay-off the government is hoping to sell at the fourth World Geothermal Congress opening Sunday on the Indonesian resort island of Bali. The six-day event will attract some 2,000 people from more than 80 countries.

“An investment of 12 billion dollars is needed to add 4,000 MW capacity,” energy analyst Herman Darnel Ibrahim said, putting into context the recent announcement of 400 million dollars in financing from lenders including the World Bank and the Asian Development Bank (ADB).

“Field exploration can take from three to five years, suitability studies for funding takes a year, while building the plant itself takes three years,” he added.

If there is any country in the world where geothermal makes sense it is Indonesia. Yet despite its natural advantages, it lags behind the United States and the Philippines in geothermal energy production.

Southeast Asia’s largest economy and the world’s third biggest greenhouse gas emitter exploits only seven geothermal fields out of more than 250 it could be developing.

The case for geothermal has become stronger with the rapid growth of Indonesia’s economy and the corresponding strain on its creaking power infrastructure.

The archipelago of 234 million people is one of the fastest growing economies in the Group of 20 but currently only 65 percent of Indonesians have access to electricity.

The goal is to reach 90 percent of the population by the end of the decade, through a two-stage plan to “fast-track” the provision of an extra 10,000 MW by 2012, mostly through coal, and another 10,000 MW from clean sources like volcanoes by 2014.

President Susilo Bambang Yudhoyono’s pledge to slash greenhouse gas emissions by 26 percent against 2005 levels by 2020 has also spurred the push to geothermal.

Many of the best geothermal sources lie in protected forests, so the government aims to allow the drilling of wells inside conservation areas while insisting that the power plants themselves be outside.

Geothermal fans welcomed the recent completion of negotiations between a consortium of US, Japanese and Indonesian companies and the state electricity company, Perusahaan Listrik Negara, over a 340 MW project on Sumatra island.

The Sarulla project will be Indonesia’s second biggest geothermal plant, after the Wayang Windu facility in West Java.

“The Sarulla project is a perfect example of how Indonesia can realise its clean energy and energy security goals by partnering with international firms,” US Ambassador Cameron Hume wrote in a local newspaper.

Several firms such as Tata and Chevron have submitted bids to build another geothermal plant in North Sumatra, with potential for 200 MW.

Engineers from the University of Cincinnati devise a foam that captures energy and removes excess carbon dioxide from the air — thanks to semi-tropical frogs.

For decades, farmers have been trying to find ways to get more energy out of the sun.

In natural photosynthesis, plants take in solar energy and carbon dioxide and then convert it to oxygen and sugars. The oxygen is released to the air and the sugars are dispersed throughout the plant — like that sweet corn we look for in the summer. Unfortunately, the allocation of light energy into products we use is not as efficient as we would like. Now engineering researchers at the University of Cincinnati are doing something about that.

The researchers are finding ways to take energy from the sun and carbon from the air to create new forms of biofuels, thanks to a semi-tropical frog species. Their results have just been published online in “Artificial Photosynthesis in Ranaspumin-2 Based Foam” (March 5, 2010) in the journal “Nano Letters.” (It will be a cover story for the print edition in the fall.)

Research Assistant Professor David Wendell, student Jacob Todd and College of Engineering and Applied Science Dean Carlo Montemagno co-authored the paper, based on research in Montemagno’s lab in the Department of Biomedical Engineering. Their work focused on making a new artificial photosynthetic material which uses plant, bacterial, frog and fungal enzymes, trapped within a foam housing, to produce sugars from sunlight and carbon dioxide.

Foam was chosen because it can effectively concentrate the reactants but allow very good light and air penetration. The design was based on the foam nests of a semi-tropical frog called the Tungara frog, which creates very long-lived foams for its developing tadpoles.

“The advantage for our system compared to plants and algae is that all of the captured solar energy is converted to sugars, whereas these organisms must divert a great deal of energy to other functions to maintain life and reproduce,” says Wendell. “Our foam also uses no soil, so food production would not be interrupted, and it can be used in highly enriched carbon dioxide environments, like the exhaust from coal-burning power plants, unlike many natural photosynthetic systems.”

He adds, “In natural plant systems, too much carbon dioxide shuts down photosynthesis, but ours does not have this limitation due to the bacterial-based photo-capture strategy.”

There are many benefits to being able to create a plant-like foam.

“You can convert the sugars into many different things, including ethanol and other biofuels,” Wendell explains. “And it removes carbon dioxide from the air, but maintains current arable land for food production.”

“This new technology establishes an economical way of harnessing the physiology of living systems by creating a new generation of functional materials that intrinsically incorporates life processes into its structure,” says Dean Montemagno. “Specifically in this work it presents a new pathway of harvesting solar energy to produce either oil or food with efficiencies that exceed other biosolar production methodologies. More broadly it establishes a mechanism for incorporating the functionality found in living systems into systems that we engineer and build.”

The next step for the team will be to try to make the technology feasible for large-scale applications like carbon capture at coal-burning power plants.

“This involves developing a strategy to extract both the lipid shell of the algae (used for biodiesel) and the cytoplasmic contents (the guts), and reusing these proteins in the foam,” says Wendell. “We are also looking into other short carbon molecules we can make by altering the enzyme cocktail in the foam.”

Montemagno adds, “It is a significant step in delivering the promise of nanotechnology.” By: Wendy Beckman, redOrbit

Jad Mouawad – The oil giant Exxon Mobil, whose chief executive once mocked alternative energy by referring to ethanol as “moonshine,” is about to venture into biofuels.

On Tuesday, Exxon plans to announce an investment of $600 million in producing liquid transportation fuels from algae — organisms in water that range from pond scum to seaweed. The biofuel effort involves a partnership with Synthetic Genomics, a biotechnology company founded by the genomics pioneer J. Craig Venter.

The agreement could plug a major gap in the strategy of Exxon, the world’s largest and richest publicly traded oil company, which has been criticized by environmental groups for dismissing concerns about global warming in the past and its reluctance to develop renewable fuels.

Despite the widely publicized “moonshine” remark a few years ago by Exxon’s chairman and chief executive, Rex W. Tillerson, the company has spent several years exploring various fuel alternatives, according to one of its top research officials.

“We literally looked at every option we could think of, with several key parameters in mind,” said Emil Jacobs, vice president for research and development at Exxon’s research and engineering unit. “Scale was the first. For transportation fuels, if you can’t see whether you can scale a technology up, then you have to question whether you need to be involved at all.”

He added, “I am not going to sugarcoat this — this is not going to be easy.” Any large-scale commercial plants to produce algae-based fuels are at least 5 to 10 years away, Dr. Jacobs said.

Exxon’s sincerity and commitment will almost certainly be questioned by its most galvanized environmentalist critics, especially when compared with the company’s extraordinary profits from petroleum in recent years.

“Research is great, but we need to see new products in the market,” Kert Davies, the research director at Greenpeace, said. “We’ve always said that major oil companies have to be involved. But the question is whether companies are simply paying lip service to something or whether they are putting their weight and power behind it.”

But if it proves a bona fide effort, Exxon’s move into biofuels, long the preserve of venture capital firms and biotech start-ups, could provide a big push to the Obama administration’s policy of encouraging more renewable energy.

Currently, about 9 percent of the nation’s liquid fuel supply comes from biofuels — most of it corn-based ethanol. And by 2022, Congress has mandated that biofuel levels reach 36 billion gallons.

But developing biofuels has been tricky, and Mr. Tillerson has not been alone in his skepticism. Many environmental groups and energy experts have been critical of corn-derived ethanol, because of its lower energy content and questionable environmental record.

According to Exxon, algae could yield more than 2,000 gallons of fuel per acre of production each year, compared with 650 gallons for palm trees and 450 gallons for sugar canes. Corn yields just 250 gallons per acre a year.

Exxon’s partnership with Synthetic Genomics is also a vote of confidence in the work of Dr. Venter, a maverick scientist best known for decoding the human genome in the 1990s. In recent years, he has focused his attention on a search for micro-organisms that could be turned into fuel.

“Algae is the ultimate biological system using sunlight to capture and convert carbon dioxide into fuel,” Dr. Venter said.

Algal biofuel, sometimes nicknamed oilgae by environmentalists, is a promising technology. Fuels derived from algae have molecular structures that are similar to petroleum products, including gasoline, diesel and jet fuel, and would be compatible with the existing transportation infrastructure, according to Exxon.

Continental Airlines, for example, has demonstrated the fuel’s viability in a test flight of an airplane powered in part by algae-based fuel.

The Pentagon has also been looking at alternative fuels, including algae, to reduce the military’s dependence on oil.

And while cost-effective mass production of algae has eluded researchers so far, it holds potential advantages over other sources of biofuels. Algae can be grown in areas not suited for food crops, using pools of brackish water or even farming them in seawater.

Algae also has another benefit, which could eventually help cut greenhouse gas emissions that cause global warming. Like any plant, it needs carbon dioxide to grow. But Exxon and Synthetic Genomics hope to genetically engineer new strains of algae that can absorb huge amounts of carbon dioxide — like that emitted by power plants, for example.

Exxon’s investment includes $300 million for in-house studies and “potentially more” than $300 million to Synthetic Genomics “if research and development milestones are successfully met,” Exxon said.
