WASHINGTON--Cooperation on clean energy could be a high point in U.S.-China relations leading to benefits for both countries, government and business officials said ahead of a summit between Chinese President Hu Jintao and President Barack Obama this week.

Disputes between the world's two largest economies and energy consumers over China's wind power subsidies and its slowdown in exports of rare earth minerals, used in everything from wind turbines to cell phones, have dominated headlines in recent months.

The countries are also having wider arguments. The United States says China's currency, the yuan, is undervalued and … Read more

WASHINGTON--The Environmental Protection Agency said today it will delay for three years requiring biomass-fired boilers to have permits for emitting carbon dioxide emissions.

"We are working to find a way forward that is scientifically sound and manageable for both producers and consumers of biomass energy. In the coming years, we will develop a common sense approach that protects our environment and encourages the use of clean energy," said EPA Administrator Lisa Jackson.

The EPA said that it plans to finish by July a rulemaking that will defer permitting requirements for CO2 emissions from biomass-fired and other biogenic sources … Read more

Having tracked traditional weather data for years, Earth Networks is taking on greenhouse gases.

Formerly named AWS Convergence Technologies and operators of the Weather Bug Web application, Earth Networks said today it will invest $25 million over five years to equip about 100 locations worldwide with sensors to measure the concentration of greenhouse gases in the atmosphere, including carbon dioxide and methane.

The company will collaborate with the Scripps Institute for Oceanography in La Jolla, California to gather and analyze the data and combine it with weather-related data. Earth Networks CEO Robert Marshall and Scripps director Dr. Tony Haymet are … Read more

SINGAPORE--The outcome of U.N. climate talks in Mexico held this month should boost steps in Asia to curb greenhouse gas emissions, with China a likely bright spot in 2011, a senior analyst at a leading U.S. think tank said.

The talks helped put the troubled U.N. negotiations back on track but failed to agree on a broader pact meant to avert every more extreme droughts, floods, heat waves, and rising sea levels.

Across the region, China, India, Japan, South Korea, Australia, and Taiwan are working on myriad policy steps to put a price on carbon emissions, drive … Read more

The Environmental Protection Agency issued an official guidance document yesterday recommending that all U.S. schools remove fluorescent lighting made before 1979 from their buildings.

It's been determined that florescent light fixtures made before 1979 contain polychlorinated biphenyl insulation in their ballasts, and that as the insulation breaks down, it releases PCBs into the air of a building.

Until the late 1970s polychlorinated biphenyls were among the chemicals frequently used in electronics and construction materials. PCBs are now known to be cancer-causing as well as irritating to the immune, reproductive, nervous, and endocrine systems in humans who are exposed … Read more

The United States risks major supply disruptions of rare earth metals used in clean energy products unless it diversifies its sources of the minerals, the Energy Department warns in a report released today.

The United States and other countries are worried that China, which controls 97 percent of the world trade in rare earth metals, will use those supplies as a political weapon and cut back their export when it is in a dispute with another country or to grow China's clean energy technology sector.

"The availability of a number of these materials is at risk due to … Read more

LG Electronics has committed to replacing conventional magnesium used in its mobile phones to a more environmentally friendly magnesium alloy dubbed eco-magnesium. To be rolled out by 2012, this would effectively reduce carbon dioxide emissions by 4kg for every handset manufactured.

"Eco-magnesium is one of LG's key strategies in our ongoing effort to transform LG into a leader in more environmentally responsible manufacturing," President and Chief Technology Officer Skott Ahn said in a statement.

LG claims that almost no sulphur hexafluoride, which is used in the casting of magnesium and which LG cites as one of the … Read more

CANCUN, Mexico--Mexico is pushing parties at the United Nations climate change meeting to strive for the best possible deal, although even the most ambitious agreement will fall short of what is needed to deal with climate change.

Acknowledging that thorny issues such as agreeing to a second round of greenhouse gas emissions cuts under the Kyoto Protocol are unlikely to be resolved at the talks at the beach resort of Cancun, Mexico's top climate change diplomat told reporters that he feels a major step forward could be made.

"The big challenge is not to just capture in a … Read more

Look at who's logging supercomputing time these days and you are likely to get a glimpse of some major innovations on the horizon.

The U.S. Department of Energy announced today it has just granted the largest award ever of the department's supercomputing time through it's Innovative and Novel Computational Impact on Theory and Experiment (INCITE) program, now in it's sixth year.

The large award, a total of 1.7 billion hours distributed over 57 projects, was partially attributed to the fact that the Energy Department has been expanding its supercomputing capacity, and, therefore, simply has the means to grant more time. But it also reflects a growing interest in using computer modeling now that it has increased in sophistication, according to the Energy Department.

The INCITE program is somewhat like the lottery in that everyone has a chance. The Energy Department has an open application process in which any scientist, whether working in the academic or commercial world, is welcome to submit a request to win supercomputing hours, and it's not restricted to energy-related science.

The winning hours are divided between two supercomputers, the IBM Blue Gene/P supercomputer at Argonne National Laboratory aka "Intrepid," and the Cray XT5 supercomputer at Oak Ridge National Laboratory aka "Jaguar," which recently lost its first place status to China's Tianhe-1A as the world's most powerful supercomputer.

Among these latest 57 recipients, are large companies like Boeing and General Electric that are going to use the time for sophisticated modeling of potential designs for jet engines and wind turbines, respectively. There are also the climate change and earthquake prediction simulation projects, as one might expect.

Most interesting to the energy sector perhaps is the Lithium/Air Battery Project led by Jack Wells, group leader of the Computational Nanotechnology Group at the Center for Engineering Science Advanced Research at Oak Ridge National Laboratory. His team will be running simulations of lithium/air battery reactions. A successful version of the air battery would be capable of storing 10 times the amount of energy as a lithium ion battery of the same weight. Such a battery might make electric cars more competitive compared to gas-powered cars since it would offer greater driving range on a single charge than current models.… Read more
