  • Greens’ Nuclear Allergy and Its Carbon Costs

    Nuclear was such a target of the environmental movement that it embraced the “anything but nuclear” policy with abandon. Is the movement’s consideration of nuclear now a case of better late than never?

  • EPA’s Carbon Regs Challenged

    In his recent State of the Union address, President Obama made only a passing reference to the American Clean Energy and Security Act of 2009 (H.R. 2545) passed by the House some months ago. “I’m eager to help advance the bipartisan effort in the Senate,” was President Obama’s acknowledgement that the House approach to controlling carbon in the U.S. faces an uncertain fate in the Senate. However, the Environmental Protection Agency’s (EPA’s) endangerment finding, released on the eve of the Copenhagen meetings last December could be the unnoticed uppercut that follows a weak congressional jab at controlling carbon.

  • Conveyor Upgrades Increase Plant Availability, Reduce Airborne Dust

    The loading and discharge of conveyor belts is the area where many, if not most, of the problems in solids conveying occur. Fortunately, a new technology provides chutes to accomplish conveyor loading and discharge without blockages while minimizing the dust generated: engineered-flow transfer chutes.

  • KnoxCheck Reports Reactor Potential and Catalyst Activity

    Adding a selective catalytic reduction (SCR) system to an operating coal-fired plant may be an expensive and time-consuming project, but the environmental benefits are without question. However, once construction is complete and operations staff assume control of the SCR, proper measurement tools are required to monitor the catalyst performance life cycle.

  • A Game Plan for Improving Boiler Operations

    Operating a boiler is not difficult, but operating a boiler safely and efficiently requires skill and proper training. Following boiler operation best practices will keep your equipment in like-new condition for years to come. This game plan includes a compendium of best practices, with web links to a number of additional key resources you should be famililar with.

  • EPA Proposes To Tighten Ozone Standard

    In one of the most far-reaching of numerous new air regulations expected from the Obama administration, the Environmental Protection Agency (EPA) has proposed to tighten the primary federal standard for ground-level ozone, the principal constituent of smog, to within a range of 60 to 70 parts per billion, saying the tougher standard is needed to protect human health.

  • DOE Official Floats NSR ‘Carve-Out’ for Some Coal Plants

    The Energy Department’s top fossil energy official said [in December that] he might seek exemption or relaxation of “new source review” requirements for certain U.S. coal-fired power plants that are boosting efficiency through retrofits if the plants are also good candidates for subsequent installation of carbon capture and storage systems.

  • Fuels Used for Power Generation Expected to Rebound in 2010

    The Energy Information Administraion has predicted that, as the economy gathers steam this year, rising demand for gasoline, crude oil, coal, and natural gas is expected to push up energy prices, aided by a projected boost in crude oil production.

    In their February 10 “state of the industry” speech to the financial community, reprinted here with permission, Edison Electric Institute leaders summarized the challenges and opportunities in the year ahead.

  • Investigation into Cause of Middletown Gas Plant Blast Continues

    Investigative efforts continue into the cause and origin of Sunday’s catastrophic explosion that killed five workers and injured 27 others at Kleen Energy System’s natural gas–fired plant being built at a remote location in Middletown, Conn.

  • Renewable Industry Groups Jointly Call for Tax Incentives, Federal RES

    Executives from U.S. wind, biomass, geothermal, hydropower, and solar industry groups on Tuesday jointly called on Congress to enact tax incentives, a federal renewable energy standard (RES), and comprehensive legislation—measures they said would accelerate growth in those energy sectors.

  • Coal Digest: Boosts for CCS Projects

    The week brought important policy and technology news concerning carbon capture and storage (CCS) from around the world. President Barack Obama unveiled a task force to make “clean coal” a reality as the European Union struck a major deal with member states for CCS funding. Caterpillar joined the FutureGen Alliance, and Siemens Energy said it would conduct a feasibility study for a novel postcombustion CCS system in West Virginia.

  • Final Approval for Calpine’s Hayward Plant Includes GHG Limits

    Calpine Corp. last week received final approval to build its long-delayed 600-MW Russell City Energy Center in the City of Hayward, Calif. The Prevention of Significant Deterioration (PSD) permit issued by the Bay Area Air Quality Management District (BAAQMD) puts limits on the natural gas–fired power plant’s carbon emissions.

  • Report: World Nuclear Power Renaissance Unlikely Before 2030

    Despite some powerful drivers, nuclear power faces too many barriers compared to other means of generating electricity, and that means that a significant expansion of nuclear power is unlikely to occur before 2030, the Centre for International Governance Innovation (CIGI), a Canadian think tank, said in a report on Thursday.

  • AREVA to Acquire CSP Firm Ausra

    French nuclear giant AREVA on Monday said it had acquired 100% of Ausra, a major U.S.-based provider of large-scale concentrated solar power (CSP) plants. The acquisition marks AREVA’s foray into solar power. The company already has major offshore wind and biomass ventures.

  • What to Make of Climate Science

    By Kennedy Maize Here at my western Maryland farm, we just got the fourth significant snowfall of the winter. We caught four inches while we were on vacation in the South Pacific in late November, over 20 inches on December 20, six inches a few days ago, and four inches last night (Feb. 2). The […]

  • Exelon to Join FutureGen Alliance

  • Countries Commit to Emissions Targets by UN Deadline

    The Secretariat of the United Nations Framework Convention on Climate Change (UNFCC) on Monday said it had received pledges from 55 countries to limit and reduce greenhouse gas (GHG) emissions by 2020. The international climate change body said the countries together accounted for about 78% of global GHG emissions from energy use.

  • SEC Votes for Disclosure of Climate Change–Related Business Risks

    The Securities and Exchange Commission (SEC) last week voted to approve interpretive guidance that calls for disclosure of climate-related business risks. These include the anticipated impact of climate change on assets and financial risks associated with compliance costs for existing and pending regulations.

  • Brazil Grants Environmental License to 11,000-MW Amazonian Hydro Project

    The Brazilian government granted an environmental license to the controversial 11,000-MW Belo Monte hydroelectric dam in the Amazon rainforest on Monday in hopes that the $17 billion project will help the country cope with growing demand.

  • Obama’s 2011 Budget Boosts Nuclear, Renewables

    President Barack Obama emphasized the role of nuclear power, offshore oil and gas exploration, and carbon capture and sequestration (CCS) in his first State of the Union speech last week. The proposed $28.4 billion Fiscal Year 2011 budget for the Energy Department released by the White House this week could provide a much-needed boost to these and other measures.

  • The Advanced Digital Fieldbus Option for Nuclear Plants

    Digital fieldbus technologies, including Foundation fieldbus and Profibus, are increasingly being used with success in the nuclear and fossil fuel power industries. This article compares a conventional control system with a Foundation fieldbus – based digital control system used in a typical circulating water system in a nuclear power plant. As shown in this example, using digital fieldbus technologies can result in significant savings in terms of installation and hardware costs.

  • Can Your Boiler Feed Pump Handle a Deaerator Pressure Transient?

    In a typical steam power plant, the boiler feedwater (BFW) pump takes suction from the deaerator (DA) and discharges high-pressure water to the boiler through the feedwater heaters. During normal operation, the DA is supplied with steam turbine extraction steam to mix with and heat the feedwater.

  • Plant Efficiency: Begin with the Right Definitions

    The race is on to claim the title of "most efficient coal-fired power plant" on the planet. However, it’s tricky identifying finalists because of the widespread misuse of the term "efficiency" and all those nagging assumptions. Let’s first establish clear definitions and then identify the title contenders.
