Bubble, Bubble, Methane is Trouble: A vast storehouse of methane under the Arctic Ocean has perforated and is starting to leak, researchers disclosed. While scientists have long been preoccupied with methane release from permafrost on mainland Siberia, the underwater stores in the adjoining East Siberian Arctic Shelf are much larger, and the release of even a small fraction could lead to a dramatic increase in global warming. Methane is a greenhouse gas at least 25 times more powerful than CO2.

Now a Word from Our Other Gases: It was a promising week in the world of fuels. A Colorado startup revealed a solar concentrator that can vaporize biomass and make high-yield synthetic fuels. British scientists explored enzymes in the gut of a boat-eating bug that could break down straw or waste wood. Meanwhile, a California newbie called Transonic Combustion claims to have invented a fuel-injection system that could boost mileage of plain old gas by 50 percent. The company registered 64 miles to the gallon in recent test drives. (more…)

The U.S. Senate voted 62 to 36 Wednesday to pass a tax extension bill (H.R. 4213) that includes a key $1 biodiesel tax credit.

The expiration of the credit on Dec. 31, 2009 put the breaks on an expanding industry and raised questions about biodiesel’s future in the U.S.

With many biodiesel plants either idle or shutdown throughout the country, the bill will reinstate the credit retroactively, extending it through Dec. 31., 2010.

Although biodiesel received a tremendous boost under the new renewable fuel standard (RFS2), without a tax credit, the industry could not compete on price with petroleum-based diesel.

Despite strong evidence that growing food crops to produce ethanol is harmful to the environment and the world’s poor, the Obama administration is backing subsidies and programs that will ensure that half of the U.S.’s corn crop will soon go to biofuel production. It’s time to recognize that biofuels are anything but green.

In light of the strong evidence that growing corn, soybeans, and other food crops to produce ethanol takes a heavy toll on the environment and is hurting the world’s poor through higher food prices, consider this astonishing fact: This year, more than a third of the U.S.’s record corn harvest of 335 million metric tons will be used to produce corn ethanol. What’s more, within five years fully 50 percent of the U.S. corn crop is expected to wind up as biofuels.

Here’s another sobering fact. Despite the record deficits facing the U.S., and notwithstanding President Obama’s embrace of some truly sustainable renewable energy policies, the president and his administration have wholeheartedly embraced corn ethanol and the tangle of government subsidies, price supports, and tariffs that underpin the entire dubious enterprise of using corn to power our cars. In early February, the president threw his weight behind new and existing initiatives to boost ethanol production from both food and nonfood sources, including supporting Congressional mandates that would triple biofuel production to 36 billion gallons by 2022.

According to the United Nations, an estimated 40 percent of the global population, or close to 2.6 billion million people do not have access to a toilet of any sort, even a pit latrine.

This has created a public health crisis in developing countries, both in terms of contaminated drinking water and poor sanitation techniques. More than one million children mostly under the age of five die each year from diarrhea resulting from this lack of sanitary conditions. While the technology exists to solve this problem, it is expensive and sometimes hard to install.

But Swedish architect and entrepreneur, Anders Wilhelmson is hoping to tackle the issue with his invention: a safe, affordable, biodegradable plastic bag called the Peepoo that can be used as a single-use toilet. (more…)

A U.S. startup has developed a process that uses concentrated solar heat to vaporize biomass into synthetic fuels, a system the company says is cleaner and more efficient and can produce twice as much fuel per ton of biomass as existing systems.

In the process, a network of solar mirrors direct sunlight at a mounted gasifying unit, heating ceramic tubes to 1,200 to 1,300 degrees Celsius. (more…)

Two billion people worldwide do their cooking on open fires, producing sooty pollution that shortens millions of lives and exacerbates global warming. If widely adopted, a new generation of inexpensive, durable cook stoves could go a long way toward alleviating this problem.

With a single, concerted initiative, says Lakshman Guruswami, the world could save millions of people in poor nations from respiratory ailments and early death, while dealing a big blow to global warming — and all at a surprisingly small cost.

“If we could supply cheap, clean-burning cook stoves to the large portion of the world that burns biomass,” says Guruswami, a Sri Lankan-born professor of international law at the University of Colorado, “we could address a significant international public health problem, and at the same stroke cut a major source of warming.”

Sooty, indoor air pollution from open wood or other biomass fires has long been linked to health problems and deaths. More recently, scientists have been surprised to learn that black carbon — not only from biomass fires but from dirty diesel engines and other sources — is a far larger contributor to global warming than previously suspected: The dark particles absorb and retain heat close to the Earth’s surface that might otherwise be reflected.

A recent report in preparation for the 12th International Energy Forum’s ministerial, scheduled in Cancun, Mexico later this month, studies and assesses the potential and limitations of biofuels.

Criticized by the Global Renewable Fuels Alliance (GRFA) as “self serving,” the report suggests that mounting evidence from research and analysis shows that the demise of the fossil fuel era is nowhere in sight and cautions against the widespread adoption of biofuels.

Authored by Claude Mandil, the former executive director of the International Energy Agency, and Adnan Shihab-Eldin, the former acting secretary general of OPEC, the report examines the extent to which biofuels could contribute meaningfully to meeting a substantial portion of future demand in the transportation sector.

The U.S. Congress is coming under increased lobbying pressure from the algal organizations to extend tax code parity to algae-based biofuels.

The Algal Biomass Organization and members of the Biotechnology Industry Organization are urging Senate Finance Committee chairman Max Baucus (D-MT) and Ranking Member Charles Grassley (R-IA) to adopt an amendment offered to the Tax Extenders Act of 2009 by Sens. Bill Nelson (D-FL), Mike Crapo (R-ID), and Jeff Bingaman D-(NM).

The amendment would ensure algae fuels receive the financial and regulatory benefits available to other advanced biofuel feedstocks and promote the development and commercialization of algae fuels. (more…)

Biofuels in Europe are struggling to meet the most basic thresholds for sustainability, according to the Times of London, which claims to have seen a government study that shows fossil fuels are better for the environment than “green fuels” made from crops.

The findings show that the United Kingdom’s biofuels mandate would result in millions of acres of forest being logged or burnt down and converted to plantations.

The study finds that some of the most basic crops used to make biofuels fail to meet the minimum sustainability standard set by the European Commission. (more…)

The European Commission confirmed on Thursday that it believes legally binding sustainability criteria for biomass used to generate heat and power are not necessary in Europe, thus ending a long process by which the European Union body has debated the utility of a supranational scheme.

The Commission, however, adopted a report on sustainability requirements for the use of solid biomass and biogas in electricity, heating, and cooling. The report makes recommendations on sustainability criteria to member states and encourages them to introduce schemes at the national level.

This strategy minimizes the risk of the development of varied and possibly incompatible criteria at the national level, leading to barriers to trade and limiting the growth of the bio-energy sector in the European Union. (more…)
