Dozens of journalists sifted through millions of leaked records and thousands of names to produce ICIJ’s investigation into offshore secrecy
A cache of 2.5 million files has cracked open the secrets of more than 120,000 offshore companies and trusts, exposing hidden dealings of politicians, con men and the mega-rich the world over.
The secret records obtained by the International Consortium of Investigative Journalists lay bare the names behind covert companies and private trusts in the British Virgin Islands, the Cook Islands and other offshore hideaways.
They include American doctors and dentists and middle-class Greek villagers as well as families and associates of long-time despots, Wall Street swindlers, Eastern European and Indonesian billionaires, Russian corporate executives, international arms dealers and a sham-director-fronted company that the European Union has labeled as a cog in Iran’s nuclear-development program.
The leaked files provide facts and figures — cash transfers, incorporation dates, links between companies and individuals — that illustrate how offshore financial secrecy has spread aggressively around the globe, allowing the wealthy and the well-connected to dodge taxes and fueling corruption and economic woes in rich and poor nations alike.
The records detail the offshore holdings of people and companies in more than 170 countries and territories.
The hoard of documents represents the biggest stockpile of inside information about the offshore system ever obtained by a media organization. The total size of the files, measured in gigabytes, is more than 160 times larger than the leak of U.S. State Department documents by Wikileaks in 2010.
To analyze the documents, ICIJ collaborated with reporters from The Guardian and the BBC in the U.K., Le Monde in France, Süddeutsche Zeitung and Norddeutscher Rundfunk in Germany, The Washington Post, the Canadian Broadcasting Corporation (CBC) and 31 other media partners around the world.
Eighty-six journalists from 46 countries used high-tech data crunching and shoe-leather reporting to sift through emails, account ledgers and other files covering nearly 30 years.
“I’ve never seen anything like this. This secret world has finally been revealed,” said Arthur Cockfield, a law professor and tax expert at Queen’s University in Canada, who reviewed some of the documents during an interview with the CBC. He said the documents remind him of the scene in the movie classic The Wizard of Oz in which “they pull back the curtain and you see the wizard operating this secret machine.”
Mobsters and Oligarchs
The vast flow of offshore money — legal and illegal, personal and corporate — can roil economies and pit nations against each other. Europe’s continuing financial crisis has been fueled by a Greek fiscal disaster exacerbated by offshore tax cheating and by a banking meltdown in the tiny tax haven of Cyprus, where local banks’ assets have been inflated by waves of cash from Russia.
Anti-corruption campaigners argue that offshore secrecy undermines law and order and forces average citizens to pay higher taxes to make up for revenues that vanish offshore. Studies have estimated that cross-border flows of global proceeds of financial crimes total between $1 trillion and $1.6 trillion a year.
ICIJ’s 15-month investigation found that, alongside perfectly legal transactions, the secrecy and lax oversight offered by the offshore world allows fraud, tax dodging and political corruption to thrive.
Offshore patrons identified in the documents include:
- Individuals and companies linked to Russia’s Magnitsky Affair, a tax fraud scandal that has strained U.S.-Russia relations and led to a ban on Americans adopting Russian orphans.
- A Venezuelan deal maker accused of using offshore entities to bankroll a U.S.-based Ponzi scheme and funneling millions of dollars in bribes to a Venezuelan government official.
- A corporate mogul who won billions of dollars in contracts amid Azerbaijani President Ilham Aliyev’s massive construction boom even as he served as a director of secrecy-shrouded offshore companies owned by the president’s daughters.
- Indonesian billionaires with ties to the late dictator Suharto, who enriched a circle of elites during his decades in power.
The documents also provide possible new clues to crimes and money trails that have gone cold.
After learning ICIJ had identified the eldest daughter of the late dictator Ferdinand Marcos, Maria Imelda Marcos Manotoc, as a beneficiary of a British Virgin Islands (BVI) trust, Philippine officials said they were eager to find out whether any assets in the trust are part of the estimated $5 billion her father amassed through corruption.
Manotoc, a provincial governor in the Philippines, declined to answer a series of questions about the trust.
Politically connected wealth
The files obtained by ICIJ shine a light on the day-to-day tactics that offshore services firms and their clients use to keep offshore companies, trusts and their owners under cover.
Tony Merchant, one of Canada’s top class-action lawyers, took extra steps to maintain the privacy of a Cook Islands trust that he’d stocked with more than $1 million in 1998, the documents show.
In a filing to Canadian tax authorities, Merchant checked “no” when asked if he had foreign assets of more than $100,000 in 1999, court records show.
Between 2002 and 2009, he often paid his fees to maintain the trust by sending thousands of dollars in cash and traveler’s checks stuffed into envelopes rather than using easier-to-trace bank checks or wire transfers, according to documents from the offshore services firm that oversaw the trust for him.
One file note warned the firm’s staffers that Merchant would “have a st[r]oke” if they tried to communicate with him by fax.
It is unclear whether his wife, Pana Merchant, a Canadian senator, declared her personal interest in the trust on annual financial disclosure forms.
Under legislative rules, she had to disclose every year to the Senate’s ethics commissioner that she was a beneficiary of the trust, but the information was confidential.
The Merchants declined requests for comment.
Other high profile names identified in the offshore data include the wife of Russia’s deputy prime minister, Igor Shuvalov, and two top executives with Gazprom, the Russian government-owned corporate behemoth that is the world’s largest extractor of natural gas.
Shuvalov’s wife and the Gazprom officials had stakes in BVI companies, documents show. All three declined comment.
In a neighboring land, the deputy speaker of Mongolia’s Parliament said he was considering resigning from office after ICIJ questioned him about records showing he has an offshore company and a secret Swiss bank account.
“I shouldn’t have opened that account,” Bayartsogt Sangajav, who has also served as his country’s finance minister, said. “I probably should consider resigning from my position.”
Bayartsogt said his Swiss account at one point contained more than $1 million, but most of the money belonged to what he described as “business friends” he had joined in investing in international stocks.
He acknowledged that he hasn’t officially declared his BVI company or the Swiss account in Mongolia, but he said he didn’t avoid taxes because the investments didn’t produce income.
“I should have included the company in my declarations,” he said.
The documents also show how the mega-rich use complex offshore structures to own mansions, art and other assets, gaining tax advantages and anonymity not available to average people.
Spanish names include a baroness and famed art patron, Carmen Thyssen-Bornemisza, who is identified in the documents using a company in the Cook Islands to buy artwork through auction houses such as Sotheby’s and Christie’s, including Van Gogh’s Water Mill at Gennep.
Her attorney acknowledged that she gains tax benefits by holding ownership of her art offshore, but stressed that she uses tax havens primarily because they give her “maximum flexibility” when she moves art from country to country.
Among nearly 4,000 American names is Denise Rich, a Grammy-nominated songwriter whose ex-husband was at the center of an American pardon scandal that erupted as President Bill Clinton left office.
A Congressional investigation found that Rich, who raised millions of dollars for Democratic politicians, played a key role in the campaign that persuaded Clinton to pardon her ex-spouse, Marc Rich, an oil trader who had been wanted in the U.S. on tax evasion and racketeering charges.
Records obtained by ICIJ show she had $144 million in April 2006 in a trust in the Cook Islands, a chain of coral atolls and volcanic outcroppings nearly 7,000 miles from her home at the time in Manhattan.
The trust’s holdings included a yacht called the Lady Joy, where Rich often entertained celebrities and raised money for charity.
Rich, who gave up her U.S. citizenship in 2011 and now maintains citizenship in Austria, did not reply to questions about her offshore trust.
Another prominent American in the files who gave up his citizenship is a member of the Mellon dynasty, which started landmark companies such as Gulf Oil and Mellon Bank. James R. Mellon – an author of books about Abraham Lincoln and his family’s founding patriarch, Thomas Mellon – used four companies in the BVI and Lichtenstein to trade securities and transfer tens of millions of dollars among offshore bank accounts he controlled.
Like many offshore players, Mellon appears to have taken steps to distance himself from his offshore interests, the documents show. He often used third parties’ names as directors and shareholders of his companies rather than his own, a legal tool that owners of offshore entities often use to preserve anonymity.
Reached in Italy where lives part of the year, Mellon told ICIJ that, in fact, he used to own “a whole bunch” of offshore companies but has disposed of all of them. He said he set up the firms for “tax advantage” and liability reasons, as advised by his lawyer. “But I have never broken the tax law.”
Of the use of nominees, Mellon said that “that’s the way these firms are set up,” and added that it’s useful for people like him who travel a lot to have somebody else in charge of his businesses. “I just heard of a presidential candidate who had a lot of money in the Cayman Islands,” Mellon, now a British national, said, alluding to former U.S. presidential candidate Mitt Romney.
“Not everyone who owns offshores is a crook.”
The anonymity of the offshore world makes it difficult to track the flow of money. A study by James S. Henry, former chief economist at McKinsey & Company, estimates that wealthy individuals have $21 trillion to $32 trillion in private financial wealth tucked away in offshore havens — roughly equivalent to the size of the U.S. and Japanese economies combined.
Even as the world economy has stumbled, the offshore world has continued to grow, said Henry, who is a board member of the Tax Justice Network, an international research and advocacy group that is critical of offshore havens. His research shows, for example, that assets managed by the world’s 50 largest “private banks” — which often use offshore havens to serve their “high net worth” customers — grew from $5.4 trillion in 2005 to more than $12 trillion in 2010.
Henry and other critics argue that offshore secrecy has a corrosive effect on governments and legal systems, allowing crooked officials to loot national treasuries and providing cover to human smugglers, mobsters, animal poachers and other exploiters.
Offshore’s defenders counter that most offshore patrons are engaged in legitimate transactions. Offshore centers, they say, allow companies and individuals to diversify their investments, forge commercial alliances across national borders and do business in entrepreneur-friendly zones that eschew the heavy rules and red tape of the onshore world.
“Everything is much more geared toward business,” David Marchant, publisher of OffshoreAlert, an online news journal, said. “If you’re dishonest you can take advantage of that in a bad way. But if you’re honest you can take advantage of that in a good way.”
Much of ICIJ’s reporting focused on the work of two offshore firms, Singapore-based Portcullis TrustNet and BVI-based Commonwealth Trust Limited (CTL), which have helped tens of thousands of people set up offshore companies and trusts and hard-to-trace bank accounts.
Regulators in the BVI found that CTL repeatedly violated the islands’ anti-money-laundering laws between 2003 and 2008 by failing to verify and record its clients’ identities and backgrounds. “This particular firm had systemic money laundering issues within their organization,” an official with the BVI’s Financial Services Commission said last year.
The documents show, for example, that CTL set up 31 companies in 2006 and 2007 for an individual later identified in U.K. court claims as a front man for Mukhtar Ablyazov, a Kazakh banking tycoon who has been accused of stealing $5 billion from one of the former Russian republic’s largest banks. Ablyazov denies wrongdoing.
Thomas Ward, a Canadian who co-founded CTL in 1994 and continues to work as a consultant to the firm, said CTL’s client-vetting procedures have been consistent with industry standards in the BVI, but that no amount of screening can ensure that firms such as CTL won’t be “duped by dishonest clients” or sign on “someone who appears, to all historical examination, to be honest” but “later turns to something dishonest.”
“It is wrong, though perhaps convenient, to demonize CTL as by far the major problem area,” Ward said in a written response to questions. “Rather I believe that CTL’s problems were, by and large, directly proportional to its market share.”
ICIJ’s review of TrustNet documents identified 30 American clients accused in lawsuits or criminal cases of fraud, money laundering or other serious financial misconduct. They include ex-Wall Street titans Paul Bilzerian, a corporate raider who was convicted of tax fraud and securities violations in 1989, and Raj Rajaratnam, a billionaire hedge fund manager who was sent to prison in 2011 in one of the biggest insider trading scandals in U.S. history.
TrustNet declined to answer a series of questions for this article.
The records obtained by ICIJ expose how offshore operatives help their customers weave elaborate financial structures that span countries, continents and hemispheres.
A Thai government official with links to an infamous African dictator used Singapore-based TrustNet to set up a secret company for herself in the BVI, the records show.
The Thai official, Nalinee “Joy” Taveesin, is currently Thailand’s international trade representative. She served as a cabinet minister for Prime Minister Yingluck Shinawatra before stepping down last year.
Taveesin acquired her BVI company in August 2008. That was seven months after she’d been appointed an advisor to Thailand’s commerce minister — and three months before the U.S. Department of Treasury blacklisted her as a “crony” of Zimbabwean dictator Robert Mugabe.
The Treasury Department froze her U.S. assets, accusing her of “secretly supporting the kleptocratic practices of one of Africa’s most corrupt regimes” through gem trafficking and other deals made on behalf of Mugabe’s wife, Grace, and other powerful Zimbabweans.
Taveesin has said her relationship with the Mugabes is “strictly social” and that the U.S. blacklisting is a case of guilt by association. Through her secretary, Taveesin flatly denied that she owns the BVI company. ICIJ verified her ownership using TrustNet records that listed her and her brother as shareholders of the company and included the main address in Bangkok for her onshore business ventures.
Records obtained by ICIJ also reveal a secret company belonging to Muller Conrad “Billy” Rautenbach, a Zimbabwean businessman who was blacklisted by the U.S. for his ties to the Mugabe regime at the same time as Taveesin. The Treasury Department said Rautenbach has helped organize huge mining projects in Zimbabwe that “benefit a small number of corrupt senior officials.”
When CTL set Rautenbach up with a BVI company in 2006 he was a fugitive, fleeing fraud allegations in South Africa. The charges lodged personally against him were dismissed, but a South African company he controlled pleaded guilty to criminal charges and paid a fine of roughly $4 million.
Rautenbach denies U.S. authorities’ allegations, contending that they made “significant factual and legal errors” in their blacklisting decision, his attorney, Ian Small Smith, said. Smith said Rautenbach’s BVI company was set up as “special purpose vehicle for investment in Moscow” and that it complied with all disclosure regulations. The company is no longer active.
‘One Stop Shop’
Offshore’s customers are served by a well-paid industry of middlemen, accountants, lawyers and banks that provide cover, set up financial structures and shuffle assets on their clients’ behalf.
Documents obtained by ICIJ show how two top Swiss banks, UBS and Clariden, worked with TrustNet to provide their customers with secrecy-shielded companies in the BVI and other offshore centers.
Clariden, owned by Credit Suisse, sought such high levels of confidentiality for some clients, the records show, that a TrustNet official described the bank’s request as “the Holy Grail” of offshore entities — a company so anonymous that police and regulators would be “met with a blank wall” if they tried to discover the owners’ identities.
Clariden declined to answer questions about its relationship with TrustNet.
“Because of Swiss banking secrecy laws, we are not allowed to provide any information about existing or supposed accountholders,” the bank said. “As a general rule, Credit Suisse and its related companies respect all the laws and regulations in the countries in which they are involved.”
A spokesperson for UBS said the bank applies “the highest international standards” to fight money laundering, and that TrustNet “is one of over 800 service providers globally which UBS clients choose to work with to provide for their wealth and succession planning needs. These service providers are also used by clients of other banks.”
TrustNet describes itself as a “one-stop shop” — its staff includes lawyers, accountants and other experts who can shape secrecy packages to fit the needs and net worths of its clients. These packages can be simple and cheap, such as a company chartered in the BVI. Or they can be sophisticated structures that weave together multiple layers of trusts, companies, foundations, insurance products and so-called “nominee” directors and shareholders.
When they create companies for their clients, offshore services firms often appoint faux directors and shareholders — proxies who serve as stand-ins when the real owners of companies don’t want their identities known. Thanks to the proliferation of proxy directors and shareholders, investigators tracking money laundering and other crimes often hit dead ends when they try to uncover who is really behind offshore companies.
An analysis by ICIJ, the BBC and The Guardian identified a cluster of 28 “sham directors” who served as the on-paper representatives of more than 21,000 companies between them, with individual directors representing as many 4,000 companies each.
Among the front men identified in the documents obtained by ICIJ is a U.K.-based operative who served as a director for a BVI company, Tamalaris Consolidated Limited, which the European Union has labeled as a front company for the Islamic Republic of Iran Shipping Line. The E.U., the U.N. and the U.S. have accused IRISL of aiding Iran’s nuclear-development program.
‘Zone of Impunity’
International groups have been working for decades to limit tax cheating and corruption in the offshore world.
In the 1990s, the Organization for Economic Cooperation and Development began pushing offshore centers to reduce secrecy and get tougher on money laundering, but the effort ebbed in the 2000s. Another push against tax havens began when U.S. authorities took on UBS, forcing the Swiss bank to pay $780 million in 2009 to settle allegations that it had helped Americans dodge taxes. U.S. and German authorities have pressured banks and governments to share information about offshore clients and accounts and UK Prime Minister David Cameron has vowed to use his leadership of the G8, a forum of the world’s richest nations, to help crack down on tax evasion and money laundering.
Promises like those have been met with skepticism, given the role played by key G8 members — the U.S., the U.K. and Russia — as sources and destinations of dirty money. Despite the new efforts, offshore remains a “zone of impunity” for anyone determined to commit financial crimes, said Jack Blum, a former U.S. Senate investigator who is now a lawyer specializing in money laundering and tax fraud cases.
“Periodically, the stench gets so bad somebody has to get out there and clap the lid on the garbage can and sit on it for a while,” Blum said. “There’s been some progress, but there’s a bloody long way to go.”
Dumbartung Aboriginal Corporation is leading the way in trying to have something done at long last about reducing the high rates of Aboriginal youth suicide. Governments have effectively neglected the crisis while the youth suicide rates climb. Dumbartung will convene a Suicide Crisis Summit on May 21.
Robert and Selina Eggington are the directors of the Dumbartung Aboriginal Corporation which maintains a huge presence at the Clontarf Aboriginal College site in Manning, Perth – which only last week was put into total Aboriginal ownership by the Christian Brothers.
The Aboriginal youth suicide rates in the Kimberley are among not only the nation’s worst but among the world’s worst rates. Aboriginal youth suicide is an endemic tragedy throughout Western Australia and includes the Goldfields, the Western Desert, the Pilbara, the South West, the Great Southern and Perth. The stressors and underwriters of youth suicide – the high levels of unemployment, lack of substantive education opportunities, chronic and abject poverty – are pernicious throughout Aboriginal communities and especially in the remote.
Mr Eggington said Aboriginal communities grieve in an ongoing manner for the loss of their youth. “We hear of a death almost fortnightly,” said Mr Eggington.
Mr Eggington referred to the suicide of a child as young as 12 years of age.
In Mowanjum, which is near Derby, there was the death of a 12 year old girl. This tragedy was only the other day.”
It was only a few years ago that Mowanjum and Balgo recorded a spate of youth suicides.
The Coronial Inquiry which would follow, with State Coroner Alastair Hope presiding, would hear that the suicide average in these towns was nearly 100 times the State average. The Coroner slammed the Government for a lack of pre-intervention and intervention services and programs.
Mr Eggington spoke of a 15 year old girl who took her life only weeks ago in Perth, and of young men taking their lives as too common an occurrence for Aboriginal families throughout Perth and the South West of the State.
Mr and Mrs Eggington coordinate Aboriginal loss and grief programs and they have assisted hundreds of families. They too have lost a son, their boy Bob, only three years ago when he took his life.
Dumbartung runs many programs and services however also includes a “mourning room” to assist those grieving, and to let them know they are not alone and that no-one has been forgotten – well at least not forgotten by Dumbartung.
The Suicide Crisis Summit will be only three hours long and hopefully a start to something positive. Dumbartung has invited everyone – State and Federal Governments, WA Police, leading lights from the criminal justice system, Aboriginal luminaries and others to discuss the ways forward and the strategies needed to reduce suicide. They will also discuss how best to secure and expend funding for suicide prevention.
“If suicide prevention programs are working why then are statistics getting worse for our people? Why is the death rate of our people through suicide remaining at the highest in the world?” said Mr Eggington.
Last week, Premier Colin Barnett admitted that alleged billions of dollars spent on Aboriginal services and communities were not reaching the people. He has now moved to create an Aboriginal Affairs Cabinet subcommittee in an attempt to have more oversight and feedback and to do more directly for Aboriginal peoples.
“State Government expenditure on services for Aboriginal people was about $2.3 billion in 2010-11, or approximately $30,000 per person,” the Premier told Parliament on April 17.
The Premier needs to be careful when breaking down monies to a per person basis because this is not how funding works. He should have subtracted Government bureaucratic costs and contractors’ payments. Acquittal is a major issue that has been failed by design principles – acquittal as an end result should be effectively guaranteed from the outset.
“Despite this reform and investment, outcomes for Aboriginal West Australians are unacceptable,” said Premier Barnett.
But they have been accepted for far too long and if little is done about the homelessness, poverty and suicides then indeed it must be deemed as the Government accepting the state of affairs. The State Government has failed many times over on a $12 million Broome Hostel promise and instead homelessness is rife throughout the town.
“Mortality rates are two and half times higher and suicide rates three times higher (than non-Aboriginal peoples),” he said.
But he did not mention the Kimberley suicide rates.
Mental Health Minister Helen Morton and Aboriginal Affairs Minister Peter Collier will send representatives to the Suicide Crisis Summit.
Hopefully everyone invited, or their representatives, shall attend the Dumbartung Suicide Crisis Summit.
State Government and Federal Governments have let down Aboriginal communities nationwide on youth suicide. Last year, South Australia’s Tauto Sansbury started a campaign for a 24 hour Aboriginal crisis centre in Adelaide to help reduce the high rate of youth suicides. In the first 13 days of January he attended eight funerals – youth suicides. The Government promised to work towards funding a crisis centre. This has not happened. Both Labor and the Coalition in South Australia are not prepared to find the funds for a crisis centre for Aboriginal youth, and therefore no such 24 hour crisis centre exists in Adelaide but the suicides continue.

Questions raised over cause of refugee camp blaze According to official sources, the fire at Mae Surin was an accident. But several eyewitnesses and a senior police officer who headed the initial probe remain unconvinced Published: 7 Apr 2013 at 00.00Newspaper section: Spectrum Two weeks after 38 people were killed in a fire at the Mae Surin camp in Mae Hong Son province, the circumstances that led to the fatal blaze remain unclear. SUSPICIOUS SMOKE: The police officer in charge of the initial investigation said he was puzzled by the black smoke created by the blaze. House fires usually produce white smoke, he said. In the aftermath of the tragedy, which has been described as the worst to hit a border refugee camp in more than 25 years, the military has maintained a tight lid on the scene. As well as the fatalities, more than 2,300 Karen and Karenni refugees were left homeless, 100 people were injured and 400 dwellings were destroyed. While there has yet to be an official declaration of the cause of the fire, media reports have pointed to three possible explanations: a cooking accident, a forest fire and arson. Spectrum visited the camp last week to get eyewitness accounts o
Demand an end to brutal ‘sorcery’ killings in Papua New Guinea Crisis, Individuals at Risk, Petition Last week Helen Rumbali, a women's rights advocate and former school teacher, was beheaded in front of her community in Papua New Guinea after three days of unspeakable torture. Police stood by and watched, reporting that they were unable to intervene to stop the angry mob. Why was she murdered? Helen was accused of 'sorcery', and brutal attacks like this one are not uncommon. The law and police inaction effectively condone such violence. The "Sorcery Act" in PNG law offers a reduced sentence if a perpetrator of violent crime uses allegations of 'sorcery' as an excuse -- even for murder. Right now another woman and her two daughters have been captured at Lopele, Bana District Southern Bougainville. She has been accused of sorcery. We are extremely concerned for the safety of these three women.

BLACKSBURG, Va., April 4, 2013 – A team of Virginia Tech researchers has discovered a way to extract large quantities of hydrogen from any plant, a breakthrough that has the potential to bring a low-cost, environmentally friendly fuel source to the world.
“Our new process could help end our dependence on fossil fuels,” said Y.H. Percival Zhang, an associate professor of biological systems engineering in the College of Agriculture and Life Sciences and the College of Engineering. “Hydrogen is one of the most important biofuels of the future.”
Zhang and his team have succeeded in using xylose, the most abundant simple plant sugar, to produce a large quantity of hydrogen that previously was attainable only in theory. Zhang’s method can be performed using any source of biomass.
The discovery is a featured editor’s choice in an online version of the chemistry journal Angewandte Chemie, International Edition.
This new environmentally friendly method of producing hydrogen utilizes renewable natural resources, releases almost no greenhouse gasses, and does not require costly or heavy metals. Previous methods to produce hydrogen are expensive and create greenhouse gases.
The U.S. Department of Energy says that hydrogen fuel has the potential to dramatically reduce reliance on fossil fuels and automobile manufacturers are aggressively trying to develop vehicles that run on hydrogen fuel cells. Unlike gas-powered engines that spew out pollutants, the only byproduct of hydrogen fuel is water. Zhang’s discovery opens the door to an inexpensive, renewable source of hydrogen.
Jonathan R. Mielenz, group leader of the bioscience and technology biosciences division at the Oak Ridge National Laboratory, who is familiar with Zhang’s work but not affiliated with this project, said this discovery has the potential to have a major impact on alternative energy production.
“The key to this exciting development is that Zhang is using the second most prevalent sugar in plants to produce this hydrogen,” he said. “This amounts to a significant additional benefit to hydrogen production and it reduces the overall cost of producing hydrogen from biomass.”
Mielenz said Zhang’s process could find its way to the marketplace as quickly as three years if the technology is available. Zhang said when it does become commercially available, it has the possibility of making an enormous impact.
“The potential for profit and environmental benefits are why so many automobile, oil, and energy companies are working on hydrogen fuel cell vehicles as the transportation of the future,” Zhang said. “Many people believe we will enter the hydrogen economy soon, with a market capacity of at least $1 trillion in the United States alone.”
Obstacles to commercial production of hydrogen gas from biomass previously included the high cost of the processes used and the relatively low quantity of the end product.
But Zhang says he thinks he has found the answers to those problems.
For seven years, Zhang’s team has been focused on finding non-traditional ways to produce high-yield hydrogen at low cost, specifically researching enzyme combinations, discovering novel enzymes, and engineering enzymes with desirable properties.
The team liberates the high-purity hydrogen under mild reaction conditions at 122 degrees and normal atmospheric pressure. The biocatalysts used to release the hydrogen are a group of enzymes artificially isolated from different microorganisms that thrive at extreme temperatures, some of which could grow at around the boiling point of water.
The researchers chose to use xylose, which comprises as much as 30 percent of plant cell walls. Despite its abundance, the use of xylose for releasing hydrogen has been limited. The natural or engineered microorganisms that most scientists use in their experiments cannot produce hydrogen in high yield because these microorganisms grow and reproduce instead of splitting water molecules to yield pure hydrogen.
To liberate the hydrogen, Virginia Tech scientists separated a number of enzymes from their native microorganisms to create a customized enzyme cocktail that does not occur in nature. The enzymes, when combined with xylose and a polyphosphate, liberate the unprecedentedly high volume of hydrogen from xylose, resulting in the production of about three times as much hydrogen as other hydrogen-producing microorganisms.
The energy stored in xylose splits water molecules, yielding high-purity hydrogen that can be directly utilized by proton-exchange membrane fuel cells. Even more appealing, this reaction occurs at low temperatures, generating hydrogen energy that is greater than the chemical energy stored in xylose and the polyphosphate. This results in an energy efficiency of more than 100 percent — a net energy gain. That means that low-temperature waste heat can be used to produce high-quality chemical energy hydrogen for the first time. Other processes that convert sugar into biofuels such as ethanol and butanol always have energy efficiencies of less than 100 percent, resulting in an energy penalty.
In his previous research, Zhang used enzymes to produce hydrogen from starch, but the reaction required a food source that made the process too costly for mass production.
The commercial market for hydrogen gas is now around $100 billion for hydrogen produced from natural gas, which is expensive to manufacture and generates a large amount of the greenhouse gas carbon dioxide. Industry most often uses hydrogen to manufacture ammonia for fertilizers and to refine petrochemicals, but an inexpensive, plentiful green hydrogen source can rapidly change that market.
“It really doesn’t make sense to use non-renewable natural resources to produce hydrogen,” Zhang said. “We think this discovery is a game-changer in the world of alternative energy.”
Support for the current research comes from the Department of Biological Systems Engineering at Virginia Tech. Additional resources were contributed by the Shell GameChanger Program, the Virginia Tech College of Agriculture and Life Sciences’ Biodesign and Bioprocessing Research Center, and the U.S. Department of Energy BioEnergy Science Center, along with the Division of Chemical Sciences, Geosciences and Biosciences, Office of Basic Energy Sciences of the Department of Energy. The lead author of the article, Julia S. Martin Del Campo, who works in Zhang’s lab, received her Ph.D. grant from the Mexican Council of Science and Technology.
Nationally ranked among the top research institutions of its kind, Virginia Tech’s College of Agriculture and Life Sciences focuses on the science and business of living systems through learning, discovery, and engagement. The college’s comprehensive curriculum gives more than 3,100 students in a dozen academic departments a balanced education that ranges from food and fiber production to economics to human health. Students learn from the world’s leading agricultural scientists, who bring the latest science and technology into the classroom.
On April 5, ‘Beat the Blockade’ by donating $5 to WikiLeaks
We launched the ‘Beat the Blockade’ campaign site one year ago, starting with a day of action on April 5, 2012 to protest the extrajudicial financial blockade of WikiLeaks and raise vital funds for their work to continue.
While Julian Assange fights legal battles under the serious threat of extradition to the United States to face secretly drawn up espionage charges, WikiLeaks continues to analyse and publish information that reveals truths about the world, its power relationships and injustices, most recently the Stratfor release, the ‘Global Intelligence Files’. And yet they struggle to operate under an extended ban processing on payments to them by US based corporate giants Visa, MasterCard, Western Union, PayPal and Bank of America.
In August of last year the WikiLeaks website was subjected to a week long DDoS attack, and the Beat the Blockade website was able to provide WikiLeaks supporters with direct access to donation methods despite the wikileaks.org website being down. WikiLeaks tweeted ”Despite the contiued 10Gb+ DDoS attack on WikiLeaks you can still donate via our Beat the Blockade campaign site http://beattheblockade.org/ “
By logging on to beattheblockade.org on April 5 and donating at least $5 by one of the easy payment methods, people around the world can send a message to the companies engaged in the blockade – and the governments that regulate them – that censorship of a free press publisher and denying consumers their rights will not be tolerated.
Since 7th December 2010 an arbitrary and unlawful financial blockade has been imposed by Bank of America, VISA, MasterCard, PayPal and Western Union on WikiLeaks. The attack has destroyed 95% of Wikileaks’ revenue. The blockade came into force within ten days of the launch of Cablegate as part of a concerted US-based, political attack on a free press publishing organisation that has breached no law in any country, and that won the 2011 Australian Walkley Award for outstanding contribution to journalism.
This April 5, together we will Beat the Blockade by each donating $5 to WikiLeaks.
