The U.S. Department of Energy on Friday filed a 48-page appeal asking the five-member board at the Nuclear Regulatory Commission (NRC) to set aside an application for the Yucca Mountain waste repository project. The agency said that Energy Secretary Steven Chu had the authority to halt the project.

The U.S. Forest Service (USFS) on Tuesday approved a San Diego Gas & Electric (SDG&E) 120-mile transmission line from remote areas in southern California’s Imperial Valley to residences and businesses in the San Diego area.

Italy’s Enel on Monday inaugurated its hydrogen-fueled combined-cycle power plant at Fusina, near Venice. The €50 million project, the first industrial-scale facility of its kind in the world, uses 1.3 metric tons of hydrogen per hour to generate 60 million kWh a year of electricity as well as heat. It reportedly has an overall efficiency of about 42%.

Shaw Group, Toshiba Corp., and Exelon Corp. unit Exelon Nuclear Partners on Monday announced an agreement to jointly pursue opportunities to design, engineer, build, and operate new nuclear power plants in Saudi Arabia.

China is reportedly looking to build 10 nuclear reactors using AP1000 technology, including the four under construction at Sanmen in coastal Zhejiang province and at Haiyang, Shandong province.

AREVA and the Canadian province of New Brunswick last week signed a letter of intent to develop a clean energy park near the Point Lepreau nuclear station. The project would include a midsize third-generation reactor—and it wouldn’t be a prototype, AREVA has reportedly said.

Utility executives cite regulation, the environment, technology, finance, and end users as the five most critical issues facing the energy industry today, a newly released study by Platts and Capgemini finds.

GE on Tuesday invited technologists, entrepreneurs, and start-ups all over the world to enter a $200 million challenge that seeks ideas to create a smarter and cleaner power grid while also accelerating the adoption of more efficient grid technologies.

By Kennedy Maize Washington, D.C., July 8, 2010 — It’s become a cliche that government should not try to pick winners and losers in the marketplace. But cliches are useful by the circumstance that they are often correct. So now we come to government loan guarantees, a classic example of government picking winners and losers. […]

Six Japanese companies established a joint venture on Tuesday to propose new nuclear projects abroad. The companies are Tokyo Electric Power Co. (TEPCO), Chubu Electric, Kansai Electric, Toshiba, Hitachi, and Mitsubishi Heavy Industries (MHI).

The Department of Energy (DOE) last week offered a $1.45 billion conditional loan guarantee to Spain’s Abengoa to finance the construction and start-up of a concentrating solar power (CSP) generating facility in Solana, Ariz. The facility, which Abengoa claims will be the “largest CSP plant in the world,” will use the first six-hour thermal energy storage system in the U.S.

The DOE awarded a $400 million conditional loan guarantee to Abound Solar Manufacturing for the assembly of thin-film, cadmium-telluride solar modules. The project will allow the manufacturing technology to be commercially deployed for the first time ever.

The U.S. Department of Energy (DOE) and the Department of the Interior (DOI) signed a Memorandum of Understanding (MOU) last week that will strengthen the working relationship between the two agencies regarding future development of commercial renewable offshore energy projects on the U.S. Outer Continental Shelf.

The DOE today announced it would fund 10 projects aimed at developing advanced technologies for capturing carbon dioxide (CO₂) from coal combustion. The projects, valued at up to $67 million over three years, focus on reducing the energy and efficiency penalties associated with applying currently available carbon capture and storage (CCS) technologies to existing and new power plants.

A study released last week by the nonprofit American Council for an Energy-Efficient Economy (ACEEE) concludes that smart metering initiatives alone are not enough to save energy.

The U.S. Environmental Protection Agency (EPA) proposed regulations on Tuesday to tackle power plant pollution that drifts across the borders of 31 eastern states and the District of Columbia. Replacing the Bush-era Clean Air Interstate Rule (CAIR), the proposed “transport” rule seeks to reduce power plant emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx) to meet state-by-state emission reductions.

Cap-and-trade programs are featured in at least two U.S. legislative proposals to reduce carbon emissions, usually by around 80% by 2050 using a 2005 baseline. The benefits that accrue from the immense investment required to reach these goals are nebulous and don’t occur until decades after the investment. Based on my back-of-the-envelope analysis, the cost-benefit ratio of these proposals does not pass a cursory cost-benefit analysis.

Circulating fluid bed (CFB) dry scrubbing technologies provide distinct advantages over conventional spray dryer absorber scrubbers for removing SO₂ from flue gases. The CFB also competes well against wet limestone flue gas desulfurization processes typically favored for large boilers firing high-sulfur coals. With high SO₂ removal rates in a dry treatment process, the CFB scrubber appears to be the best of both technologies: a water-stingy scrubber with high SO₂ removal rates.

The U.S. Environmental Protection Agency is expected to propose an emissions standard for mercury and other hazardous air pollutants emitted by coal- and oil-fired electric generating units in March of 2011. The anticipated rule would require emission control to meet the various standards using maximum achievable control technology, as determined by the prescriptive requirements of the Clean Air Act. In response to the expected rule-making, utilities will be required to make technology decisions in order to ensure compliance. One cost-effective approach to compliance may be the use of “co-benefits” from air quality control systems (AQCSs) already in service that are designed to remove other pollutants.

An "emergency war supplemental" appropriation bill that Congress was considering at this writing has implications for the power industry: The measure includes $9 billion each for new loan guarantees for nuclear power and renewable energy projects.

American Electric Power’s (AEP’s) Cardinal Power Plant Unit 3 cooling tower in Brilliant, Ohio, was coated and lined in the spring of 2008 by a team of coatings professionals that included the plant’s project and coatings engineering staff, Sherwin-Williams (coatings supplier), Cannon Sline Industrial (contractor), and OTB Technologies (third-party inspector). The team completed the project in just 11 weeks through damp springtime conditions in the Ohio River Valley.

When it is completed, later this summer, the UK’s Drax Power Station biomass facility will become the largest dedicated cofiring project of its kind in the world. As U.S. coal-fired generators come under increasing pressure to cut emissions and take advantage of incentives to promote power generation from renewables, Drax offers an example of what is possible.

A recent survey finds utility regulators contradicting themselves on the touchy subject of nuclear power. They say they like new nukes, but their actions belie their stated beliefs.

In April, Solvay Chemicals Inc. commissioned a new facility that uses an innovative process to recover and transform sodium carbonate waste streams into a market-grade sodium bicarbonate used in air emissions control.

Fogging systems have been successfully used in the material-handling industry for more than 30 years to control explosive dust at transfer points. Today, fogging systems are an EPA Best Demonstrated Technology for subbituminous coal preparation plants.

The Energy Department’s failure to recognize an impending supply squeeze for helium-3—a nonradioactive gas produced in the agency’s nuclear weapons complex—has created a national crisis requiring White House intervention and threatening key U.S. nuclear and homeland security programs, a wide range of medical and scientific research activities and development of U.S. oil and natural gas resources, according to testimony before a House subcommittee.

Safety is the imperative for any construction project, and Duke Energy’s 630-MW Edwardsport integrated gasification combined-cycle station in Knox Country, Ind., is no exception.

Today’s coal-fired power plants face the twin challenges of improving their wet flue gas desulfurization (FGD) systems’ emission control capabilities in order to comply with environmental regulations while at the same time cutting their operational and maintenance costs. Smart strategies for retrofitting existing FGD systems can help plant personnel meet both of these objectives.

Does wasted work time equal job dissatisfaction? Two studies point in that direction.

Abengoa Solar in early May began commercial operation of Solnova 1, the company’s first 50-MW parabolic trough plant. Covering 980,000 square feet with mirrors requiring an area totaling 280 acres (Figure 2), it is one of five planned concentrating solar power (CSP) plants to be built at the Solúcar Platform in Spain. All will use a technology developed by Abengoa with experience gained from a trough pilot built in 2007. Solnova 1 will also be equipped to burn natural gas if sunlight is weak.
