U.S. issues timetable for carbon emissions cuts

Reuters

WASHINGTON--U.S. environmental regulators released a plan on Thursday for the nation's power plants and refineries to cut greenhouse gas emissions, pressing ahead with the Obama administration's strategy of tackling the pollution in the absence of federal climate legislation.

The Environmental Protection Agency said it would propose so-called performance standards on greenhouse gas emissions on both new and existing plants beginning in July for power plants and for oil refineries by December. The fossil fuel plants emit about 40 percent of U.S. greenhouse gases.

The plan resulted from an agreement with states, including California and New York, … Read more

Cisco wins more Greenpeace kudos

Cisco, once again, was the leader of the pack as Greenpeace released its latest Cool IT Leaderboard on Tuesday.

The environmental watchdog group named Cisco, Ericsson, and Fujitsu, respectively, as the three most environmentally responsible IT companies. Cisco received 70 out of 100 possible points, while Ericsson received 57 points and Fujitsu 52 points. Greenpeace praised Cisco for "making IT climate solutions an increasingly core part of its business strategy."

Cisco was in first place in the group's previous list in April, despite Google upping its public support for climate change legislation in the U.S. at … Read more

Mexico urges higher ambitions at climate talks

Reuters

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

Energy Department awards supercomputing time

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

Study warns against hyping carbon-fixing biochar

Of all the approaches to cutting carbon emissions, making charcoal and putting it in the ground as fertilizer would seem one of the least controversial. But a report published today offers words of caution around expecting too much from biochar.

Biochar, also called man-made charcoal, is made by decomposing plants and other organic materials into charcoal through pyrolysis, or slowly burning biomass at high temperatures with no oxygen. The resulting biochar can be used as a soil fertilizer, a technique used by ancient civilizations in the Amazon.

Unlike naturally decomposing organic materials, biochar holds onto carbon dioxide for hundreds or even thousands of years. For that reason, it's been touted by everyone from Virgin CEO Richard Branson to environmentalist James Lovelock as a promising method for fixing carbon dioxide in the ground. Biochar has also attracted detractors in the past few years who say that growing plants to create biochar would be a "false solution" to climate change.

Environmental advocacy group the National Resources Defense Council today published an analysis that seeks to put some perspective on the potential on biochar. The study also proposes first steps for a U.S. policy to promote production of biochar on a commercial scale (click for PDF).

An extensive study earlier this year estimated that as much as 12 percent of human-caused greenhouse gases could be offset by making biochar.

But that number best represents the technical potential of biochar, not a realistic expectation, according to the NRDC. It notes that, because there are no commercial biochar production systems, it's difficult to assess the environmental benefits and financial cost.

"The truth as to whether biochar is a cure-all or a scourge is apt to lie between the extremes, but we cannot say exactly where at present," according to the NRDC, which said it isn't in a position to endorse or discourage its development without further technical development and tests.

Among some of the concerns is the environmental impact from diverting land for biochar and the energy footprint of transporting biomass. The NRDC said that using waste biomass, such as plant residue or manure, looks like the most promising feedstock. Uncertainty around carbon markets makes it difficult to assess the costs of these systems.

Among its recommendations, the NRDC says that commercial-scale biochar facilities using slow pyrolisis use waste such as manure. It said that 5 to 10 demonstration facilities would cost between $100 million and $150 million. … Read more

Obama climate rules face fight in Congress

Reuters

analysis Republicans in the new Congress will pose a greater threat to the Obama administration's strategy to regulate greenhouse gas polluters than a plethora of industry lawsuits.

The Environmental Protection Agency, or EPA, is marching ahead with rules requiring big polluters like coal-fired power plants, oil refiners, and cement manufacturers to get permits starting January 2 to emit gases blamed for warming the planet.

President Barack Obama has always said the EPA would regulate carbon emitters if lawmakers failed to pass a climate bill.

EPA to push efficiency on big carbon emitters

Reuters

WASHINGTON--U.S. environmental regulators said on Wednesday they will not force coal plants and manufacturers to adopt specific technologies to cut greenhouse gas output, but will push them to become more energy efficient to comply with looming climate rules.

The move by the Environmental Protection Agency helped relieve some fears in the industries that the agency would require emitters to quickly invest in expensive, unproven technologies to cut output of gases blamed for global warming. But industry groups did complain they would not have enough time to comply with the rules.

The EPA is taking steps to regulate greenhouse gases because Congress failed to pass a climate bill this year. Some lawmakers and industry groups are trying to stop them from regulating.

Beginning January 2, the EPA plans to start requiring big emitters such as power plants, refineries, and cement manufacturers to obtain permits for polluting greenhouse gases.

"We believe this approach will in most cases lead to improvements in energy efficiency," Gina McCarthy, an EPA assistant administrator on air and radiation, told reporters in a teleconference.

The agency released on Wednesday guidance on the best available control technologies, or BACT, that companies should use to cut emissions of carbon dioxide and other gases. The companies will have to adhere to the guidelines when expanding or building new plants or factories, and work with state and local air authorities to decide which technology works best for them. … Read more

California unveils greenhouse gas trading plan

Reuters

SAN FRANCISCO--California unveiled its final draft of a market system to curb greenhouse gases, relaxing expected rules in the face of a weak economy in a measure that could set the tone for the nation's climate policy.

By agreeing to give away virtually all necessary permits to factories and power plants when the scheme starts in 2012 rather than sell them at auction, the state with the biggest economy and population is acknowledging the challenges of double-digit unemployment--and the reality that pollution decreases as the economy slows.

California aims to cap total emissions of gases linked to global warming and let factories and power plants trade for an ever-decreasing number of permits to emit gases. In theory, market forces will drive efficiency in the system, known as cap and trade.

There is still a debate about the economic merits of the plan, which planners in the Friday draft (PDF) estimate will shave about 0.1 percent from annual state growth.

Many Californians see such environmental regulation as positive for the economy by spurring "green" jobs. Voters on Tuesday could put on hold a climate change law, including the emissions market, but polls show the Proposition 23 challenge to the state's climate change law is set to be rebuffed.

After the failure of federal climate legislation, the fate of California's law and the details of its cap-and-trade plan are seen as a U.S. turning point--either away from addressing climate change or toward stronger action.

The state's 2006 law requires it to return to 1990 levels of greenhouse gas emissions by 2020, and the hobbled economy has produced fewer greenhouse gas emissions than expected, making the goal less onerous.

The state agency planning cap-and-trade has responded in part by ignoring a suggestion by a panel of economists last year to auction off the emissions permits. … Read more

Study: Wind thrives despite Copenhagen failure

Wind energy could be supplying 22 percent of the world's power generation by 2030--and 12 percent as soon as 2020.

That's according to the most aggressive estimate on wind energy in a report released today and funded by the Global Wind Energy Council (GWEC) and Greenpeace.

The 60-page Global Wind Energy Outlook 2010 (PDF) offers three scenarios for how the wind energy industry may develop between 2010 and 2030 depending on the political will, growing energy needs, corporate manufacturing development, and grid infrastructure changes.

The most optimistic estimate--based on what the GWEC believes would happen in the event … Read more

Chunky U.S. energy policy hard on green biz

Reuters

WASHINGTON--President Barack Obama's proposal that U.S. energy and climate policy may be implemented bit by bit means that companies will have less incentive to grow their green-energy businesses.

Obama told Rolling Stone magazine last month that following the Senate's failure to pass comprehensive climate legislation that would have put a price on greenhouse gas emissions, energy policy may have to be done in "chunks."

But if Republicans take control of either house of Congress in the November 2 elections, passing limited energy measures such as a price on carbon emissions only from power companies or a renewable-energy standard, requiring utilities produce minimum amounts of power from sources like wind and solar farms, would be improbable for the remainder of Obama's first term.

Even if Republicans fail to capture either house, and Obama can corral the votes to pass such legislation, piecemeal laws will come nowhere near a comprehensive overhaul and may even be detrimental to making lasting changes in the energy system, increasing energy security, or cutting emissions blamed for warming the planet.

"You are going to adopt policies in the order of their ease of passing rather than in the order of rational policy making," Adele Morris, policy director for climate and economics at Washington-based Brookings Institution think tank, said about taking an incremental approach to energy. "There are a lot of things that are bad ideas but are easy to pass."

As Washington struggles with energy policy, the gap between the United States and China, the world's two largest carbon polluters, is growing ahead of global climate talks in Cancun, Mexico, starting in late November. Here too, an incremental approach will likely dominate. … Read more
