    Saskatchewan and Montana officials last week said they would partner on the development of one of the largest international carbon capture and storage demonstration projects in the world. Saskatchewan Premier Brad Wall and Montana Governor Brian Schweitzer signed a memorandum of understanding (MOU) to collaborate on the construction of a “technology neutral CO2 plant at […]

  • Nuke Waste Confidence: A Confluence of Ironies

    By Kennedy Maize Here’s an interesting set of ironies. The Republican majority on the U.S. Nuclear Regulatory Commission has taken a position that, at least formally, blocks new nuclear reactors in the U.S., while the sole Democrat on the commission, Chairman Greg Jaczko, widely viewed as opposed to the agenda of the nuclear industry, has […]

  • EPA Considering Rules on Coal Waste Runoff

    The U.S. Environmental Protection Agency (EPA) is committed to issuing proposed regulations for the management of coal combustion waste by utilities by the year’s end, a senior agency official told the House Transportation and Infrastructure committee Thursday. Rules could include tightened restrictions on contaminants in wet scrubber wastewater streams.

  • LS Power Pulls Plug on 750-MW Midland, Mich., Project

    LS Power has abandoned a proposed 750-MW pulverized coal power project in Midland, Mich., citing economic and regulatory uncertainties.

  • TVA Stands by Bellefonte COLA; Progress Energy Delays Levy County Nuke Units

    The Tennessee Valley Authority (TVA) last week said it would continue pushing for regulatory approval of its proposed Bellefonte nuclear plant, though the NuStart consortium had shifted priority to another project, while Progress Energy Florida delayed the commercial start of its proposed Levy County plant by almost two years while it awaits a combined construction and operation license (COL)  from the Nuclear Regulatory Commission (NRC).

  • Deal in Kansas Means Sunflower Will Get Coal Plant

    Kansas’ new governor, Mark Parkinson, and Sunflower Electric Power Corp. have reached a compromise that would allow that company to build an 895-MW coal plant in the western part of the state in exchange for Republican support for a state bill that encourages production of more renewable energy.

  • Bills to Spur Marine Energy Development Introduced in Congress

    Legislation introduced last week by members of the House of Representatives and the Senate could spur development of U.S. marine and hydrokinetic energy resources—a sector in which the U.S. has lagged behind other countries.

  • New Bill Could Tighten Grid Cybersecurity

    Ramped-up concerns about the security of the U.S. power grid and media reports that said cyberspies had infiltrated it have prompted the introduction of a congressional bill that would increase the authority of the Department of Homeland Security (DHS) and the Federal Energy Regulatory Commission (FERC) to help reduce the grid’s vulnerability.

  • NRC Grants First Ever 40-Year Nuclear Facility License Renewal

    The Nuclear Regulatory Commission (NRC) has renewed the first ever 40-year-operating license of a nuclear facility in the U.S., granting it to AREVA NP’s nuclear fabrication facility in Richland, Wash.

  • DOE Pours Recovery Act Funding into Wind, Laboratory Improvements

    The Department of Energy (DOE) last week said it would provide $93 million from the American Recovery and Reinvestment Act to support further development of wind energy in the U.S., as well $100 million from the act for facility and infrastructure improvements at the National Renewable Energy Laboratory (NREL).

  • Powering the People: India’s Capacity Expansion Plans

    India has become a global business power even though hundreds of millions of its citizens still live in poverty. To sustain economic growth and lift its people out of poverty, India needs more — and more reliable — power. Details of government plans for achieving those goals demonstrate that pragmatism may be in shorter supply than ambition and political will.

  • Interest in Solar Tower Technology Rising

    Though solar thermal tower technology has been around since the 1970s, to date, only one plant in the world commercially generates electricity: Abengoa Solar’s 11-MW PS10 tower just outside Seville, in Spain’s Andalucía desert has been grid-connected since early 2007. Because the technology relies on heat from solar energy that is reflected by mirror arrays (heliostats) onto a tower-mounted receiver, installations tend to be site-specific, expensive, and high-maintenance.

  • The Foreign Investment Factor (supplement to Powering the People: India’s Capacity Expansion Plans)

    Recognizing that the long-term sunk cost, long project planning and construction timeframe, and high-risk portfolio make it difficult for private investors to raise funds whose maturity matches project completion dates, the Indian government has since 1991 allowed 100% foreign direct investment in the power sector.

  • Boiler-Tuning Basics, Part II

    Boilers have enormous thermal mass and are relatively slow to react. Turbines are nimble and quickly answer an operator’s command. Coordinating an entire plant requires an intimate knowledge of both systems and selecting the right logic tools to bring them together.

  • Tidal Barrages Could Power 5% of UK

    Barrages across the Solway Firth, Morecambe Bay, and the Mersey and Dee estuaries in the northwest UK could provide more than 5% of the nation’s electricity and meet half the region’s electricity, a study by engineers at the University of Liverpool has found.

  • Nuclear Uprates Add Critical Capacity

    New-generation nuclear plants may be having trouble getting out of the gate, but that doesn’t mean that nuclear capacity additions are at a standstill. In fact, the 104 operating nuclear units in the U.S. have added substantial new capacity in the form of reactor and plant uprates over the past 20 years. Power uprates alone have added more than 5,600 MW since 1998 — the equivalent of five new nuclear plants.

  • Geologists Map Carbon-Trapping Rock Formations

    U.S. scientists concerned about carbon dioxide (CO2) leaks from sequestration attempts have been pursuing the option of natural chemical reactions within the earth to turn the carbon back into a solid, and they have identified an abundant supply of large rock formations around the world that could be used a vast sink for the heat-trapping gas.

  • Birth Pangs of the Nuclear Renaissance

    The much-ballyhooed U.S. nuclear renaissance, with a few exceptions, is running late, thanks to the usual Washington bureaucratic quagmire plus the added risk resulting from crumbling financial markets. The future doesn’t look much brighter. The poor outlook for Yucca Mountain and the new administration’s general indifference to nuclear power have made a rebirth of the nuclear industry an even higher-risk proposition than before.

  • Tapping Geothermal Energy with a Comprehensive Strategy

    Geothermal energy in Europe may have been used for centuries — it was popularized by the Romans and adopted by the Turks — but geothermal-generated electricity was first produced at Larderello, Italy, in 1904. Since then, its growth on the continent has shot up to 820 MW. But, according to the European Renewable Energy Council, the resource’s full potential has barely been harnessed.

  • Renewable Project Finance Options: ITC, PTC, or Cash Grant?

    Dozens of institutional investors in U.S. renewable energy projects pulled out of the market when the nation’s liquidity reserves dried up late last year. Some left the renewable market sector in search of more lucrative investment opportunities. Others found themselves unable to take advantage of the attractive tax credits because they themselves lacked profits against which to use the credits. The American Recovery and Reinvestment Act of 2009, approved February 13, changed the investor ground rules — again.

  • Switchgear Technology Surpasses 1 Million Volts

    Swiss power technology group ABB, which pioneered gas-insulated switchgear 50 years ago, in April announced it had commissioned switchgear rated to handle 1,100 kV. The development marks the biggest leap in capacity and efficiency of AC power transmission in more than two decades.

  • Two-Pump Fuel Recirculating System

    The Duplex Pump Unit (FRS 660-11-DPU-UL) from RCI Technologies is the newest addition to that company’s line of diesel fuel purifiers and fuel recirculating systems (FRSs). Designed to automatically circulate and clean the fuel in customers’ fuel storage tanks on a preprogrammed schedule, the DPU features two fuel pumps, which operate alternately to circulate fuel through the system. Whereas RCI’s other FRS units utilize a single pump, the duplex pump offers backup in the event of a primary system failure. All FRS units employ filter-less technology. The control system is housed in a weatherproof, NEMA 4, key-lockable cabinet, and the system is equipped with alarms to alert the user in the event of pump failure, purifier high water level, system high pressure, or fuel catch basin leak.

  • Gas Hydrates: Fuel of the Future?

    Gas hydrates, a form of natural gas that forms when methane from the decomposition of organic material comes into contact with water at low temperatures and high pressures, could play a role — even if a small one — in future fuel supplies, researchers attending a March meeting organized by the American Chemical Society suggested.

  • Energy Bubble, Anyone?

    When the housing bubble burst, it exposed an unseemly alliance between special interests and the financial sector. Activists wanted homes for all at any cost, and lenders were happy to oblige despite the inherent risk.

  • Extreme Temperature Vibrating Fork

    Emerson Process Management launched a new extreme temperature version of its Rosemount 2130 vibrating fork liquid level switch that is designed for use in extreme temperatures — from – 94F to 500F (–70C to 260C). The new version includes a low-density option suitable for liquids with specific gravity down to 0.5 (500 kg/m 3). In addition to built-in fault-monitoring/self-checking diagnostics to detect corrosion of the forks or any internal or external damage or breaks in the internal electrical wiring, it features a "heartbeat" LED, which provides instant visual indication that the unit is operational. The unit requires no onsite calibration and is available in 316L stainless steel, corrosion-resistant alloy C wet side, or a range of other stainless steel and aluminum options.

  • Advanced Vibration-Monitoring Technology

    Sweden’s SKF Reliability Systems introduced the SKF Microlog Analyzer AX, an advanced vibration-monitoring technology. With simultaneous triaxial or four-channel vibration measurement capability, the unit speeds up data collection and saves time in monitoring rounds. The 806 MHz Xscale processor also means faster real-time rate and display updates. An available range of application modules allows users to create a custom device to perform several advanced tasks, such as impact tests, digital recording, modal analysis, transient phenomena analysis, and quality inspections.

  • Digital Harmonics Filters

    Schaffner’s filter series now includes ECOsine active harmonics filters — compact, digital units that continuously measure and analyze disturbances in the power network and provide an exactly opposite compensation current. In doing so, the filters actively adapt to changing network topologies and respond in less than half a millisecond, before damage from the disturbances can occur. The improved power quality of the new filters minimizes the risk of downtime and process interruptions.

  • Spain Is Tilting at Windmills

    President Barack Obama has praised Spain as a global leader in renewable electricity generation and has lauded its success at creating so-called "green jobs." However, a recent Spanish university study concluded that Spain’s mad rush to meet overly aggressive renewable standards has destroyed jobs and driven up the real cost of electricity, without cutting carbon emissions.

  • Reusable Mini-Silo System

    DW Global Group’s recently announced dry bulk hopper mini-silo system — comprising one or more reusable, translucent containers — is designed for companies wanting to replace fiber drums, cardboard boxes, wood pallets, and super sacks. The rugged plastic containers — lids included — multitask as shipping, storage, and dispensing systems. Each hopper has a valve at the bottom for easy flow of material from hoppers to the manufacturing machine. The system allows for stacking of up to three units with a total weight of as much as 2,400 pounds. According to DW Global, the investment for a multi-purpose dry bulk hopper system can be "as little as $5,000 to $10,000, with a return-on-investment in less than a year." (www.dwglobalgroup.com)
