  • Cost-Cutting Nanoparticle Electrode for Batteries

    Using nanoparticles of a copper compound to develop an inexpensive and durable high-powered battery electrode could be the breakthrough solution to the problem of sharp drop-offs in the output of wind and solar systems, scientists at Stanford University say.

  • Condenser Backpressure High? Check Vacuum System Sizing

    In a power plant, the primary use of vacuum systems is to remove air and other noncondensable gases from the shell side of the condenser in order to maintain design heat transfer and thus design vacuum. If holding condenser vacuum is a persistent problem, one often-overlooked cause is an inadequately sized vacuum system.

  • New Report Further Polarizes Solar Manufacturers on China-Tariff Issue

    A new report commissioned by the Coalition for Affordable Solar Energy (CASE)—an alliance of about 70 solar companies whose rallying message declares global competition has made solar energy a reality around the world—finds that if the U.S. government imposes a 100% tariff on imported solar PV cells and modules from China, the nation could see as many as 50,000 net lost jobs over the next three years.

  • EPA Finalizes Air Toxics Rule

    The Environmental Protection Agency (EPA) on Dec. 21 issued its final Mercury and Air Toxics Standards (MATS), which will require about 40% of all coal-fired power plants in the U.S. to deploy pollution control technologies to curb emissions of mercury and other air pollutants such as arsenic and cyanide within three years.

  • Novel Floating Wind Turbine Deployed in the Atlantic

    A semi-submersible structure supporting a 2-MW wind turbine was towed nearly 350 kilometers (217.5 miles) to water depths of about 35 meters (114.8 feet) into open Atlantic waters and deployed off the coast of Aguçadoura, Portugal, last November.

  • Avoiding Flow-Induced Sympathetic Vibration in Control Valves

    Compressible fluid flow through control valves will inevitably cause some form of flow-induced vibration in the fluid system. Identifying the type and cause of the vibration requires detective work. Determining the design changes required in the valve and fluid system to prevent the vibration from occurring requires advanced analytical techniques.

  • Environmental Rules Prompt Closure of More Coal Plants, Pause Development of New Plant

    Citing newly finalized and proposed environmental regulations that could make costs uncertain, FirstEnergy Corp. on Thursday said it would shutter six older coal-fired power plants with capacities totaling 2,689 MW in Ohio, Pennsylvania, and Maryland by September. The same uncertainties prompted a major backer of a $2 billion coal-fired power plant planned for Washington County in Georgia to pull its funding.

  • Top 12 Energy Issues for ’12

    With the 2012 election year upon us, it promises to be an interesting time for energy politics and policy. Here are 12 (really 13 because of some creative headline writing) issues that will keep the sector hopping this year.

  • One Step Forward, Two Steps Back for CCS Projects

    Last December, as Spain’s national carbon capture and storage (CCS) research laboratory Fundación Ciudad de la Energía (CIUDEN) began a much-watched testing phase of oxycombustion in its 30-MWth circulating fluidized bed (CFB) boiler in Cubillos del Sil, Vattenfall scrapped the €1.5 billion ($2 billion) Jänschwalde CCS demonstration project that it had planned to build and begin operating by 2015 in the German federal state of Brandenburg.

  • Heed New Seismic Model, NRC Tells Nuclear Plants in Central, Eastern U.S.

    The Nuclear Regulatory Commission (NRC) on Tuesday urged owners of 62 nuclear power plants in the Central and Eastern U.S.—facilities housing 96 of the nation’s 104 commercial nuclear reactors—to reevaluate seismic hazards using a new seismic model and information from a recent report.

  • Taking Energy Independence Seriously

    At year end 2011, as Americans emptied their wallets at the gas pump and crude oil reached almost $100 a barrel, OPEC kingpin Saudi Arabia reported an $81.6 billion 2011 budget surplus.

  • Indonesia Inaugurates Three Coal Plants

    Indonesian state-owned utility Perusahaan Listrik Negara (PLN) formally launched operations at three new coal-fired power plants on Dec. 28.

  • Failed Insulator Triggers Loss of Offsite Power at Byron Nuclear Plant

    A failed electrical insulator at a switchyard at Exelon Generation Co.’s two-unit Byron nuclear plant in Lisle, Ill., has been blamed for the loss of offsite power on Monday morning that automatically shut down Unit 2 and forced Exelon to declare an “Unusual Event.”

  • EPA Releases, Federal Court Blocks CSAPR

    The U.S. Court of Appeals for the District of Columbia Circuit temporarily blocked the Cross-State Air Pollution Rule (CSAPR) just two days before it was set to go into effect. The federal court ordered the Environmental Protection Agency (EPA) to continue administering the previously promulgated Clean Air Interstate Rule (CAIR) until a final decision can be made on the merits of the rule, likely this summer or fall.

  • POWER Digest (February 2012)

    ANDRITZ to Rebuild Oldest Egyptian Nile Dam. Austrian firm ANDRITZ HYDRO on Dec. 22 won a $138.4 million contract from the Egyptian Ministries of Energy and Water Resources for the supply and installation of four bulb turbines, generators, and the electrical and hydro-mechanical equipment to rebuild the Assiut barrage—the oldest dam in the Egyptian section […]

  • Ductile and Flexible Seal Rings

    Milan-based ATO S.r.l. has introduced a series of flexible seal rings made of KetaSpire polyetheretherketone (PEEK) resin, which is made by Solvay Specialty Polymers.

  • Blue Ribbon Commission: U.S. Nuclear Waste Policy “Completely Broken Down”

    The 15-member Blue Ribbon Commission (BRC) appointed by Energy Secretary Steven Chu in January 2010 to provide comprehensive recommendations for a long-term solution to managing and disposing the nation’s spent nuclear fuel and high-level radioactive waste released its much-anticipated final report last week.

  • Audit Your Coal Dust Prevention Program

    The hazards of coal dust accumulation in power plants are familiar to coal-fired plant operators. Operators of plants that burn Powder River Basin coal are particularly aware of necessary housekeeping and fuel-handling practices, but any plant that allows excessive amounts of coal dust to accumulate is playing Russian Roulette with its staff and equipment.

  • Federal Judge Ruling Poses Another Hurdle for Sunflower Coal Plant

    A federal district court judge on Tuesday ruled that the Rural Utilities Service (RUS), an arm of the U.S. Department of Agriculture (USDA), must complete an environmental impact study (EIS) before any approvals or other major federal action can be taken on the $2.8 billion expansion at Sunflower Electric Power Corp.’s coal plant in Holcombe, Kansas. The ruling may delay construction of the 875-MW plant, a politically controversial project in the Kansas Legislature.

  • The Broken Window

    The expectation of millions of "green jobs" has disappeared from public debate. Today, the debate is narrowly focused on "jobs" and selecting the best approach to developing permanent jobs, regardless of color. Some look to the government to create jobs through regulation or subsidy, and others trust companies operating under free market principles to create permanent jobs.
