  • Biomass Electricity More Efficient than Ethanol, Researchers Say

    Biomass — plant matter that’s grown to generate energy — converted into electricity could result in 81% more transportation miles and 108% more emissions offsets than ethanol, according to U.S. researchers. In addition, the electricity option would be twice as effective at reducing greenhouse gas (GHG) emissions. The study, published in the May 22 issue […]

  • Combined-Cycle Carbon Capture: Options and Costs, Part I

    Uncertainty about CO2 emissions legislation is prompting power plant owners to consider the possibility of accommodating "add-on" CO2 capture and sequestration solutions for coal-fired plants in the future. Those same plant owners may be overlooking the possibility that future natural gas – fired combined cycles will also be subject to CO2 capture requirements. This month we examine the capture options. In a future issue, Part II will present the installation and operating costs of different carbon capture technologies.

  • DOE Funds Electrification of Transportation Sector

    On August 5, President Barack Obama announced that 48 new advanced battery and electric drive projects will receive $2.4 billion in funding from the Department of Energy under the American Recovery and Reinvestment Act.

  • New Natural Gas–Fired Projects on an Upswing

    Over the past decade, the development of new natural gas – fired generating assets has been similar to an amusement park roller coaster ride — very high peaks and the lowest of lows, with fast and stomach-churning movement between. Expect the ride to continue into the near future.

  • Optimizing the Life-Cycle Cost of Human Capital

    Is it possible to develop a business model whereby an economic dip can be used to a market advantage? One client uses a sports analogy to describe this opportunity: "We are between seasons, and we have an opportunity to recruit and retool our team for the future." This just might be the right time to retool your human resources processes to avoid past hiring mistakes and adopt new hiring practices that will maximize the life-cycle value of your company’s human capital.

  • Global Warming Has Been Very, Very Good for Me

    If what we have seen this spring and summer is global warming, my farm says “bring it on.” That sense that there is no climate crisis may present the Obama administration with a difficult choice between energy or health care legislation this fall in Congress. Energy legislation likely will fail.

  • Dead Man’s Hand

    The stage is being set for negotiating a successor agreement to the Kyoto Protocol. The U.S. is trying to exert some leadership in the international climate change debate by attempting to build consensus for binding carbon emission reductions prior to the upcoming Copenhagen meeting. Meanwhile, carbon legislation is, thankfully, stalled in the Senate, and developing countries are rejecting our entreaties. You can’t win if other countries don’t want to play.

  • To Modernize the Grid, Think Smaller

    The consumer, societal, and business benefits of grid moderniaztion are unclear, because the vast majority of grid-related stimulus funding appears destined to primarily expand, not cure, the ailing system we have today.

  • Flipping the Switch: Why Utilities Need to Shed Light Now on Carbon Risk

    Carbon is poised to become an auditable and verifiable reporting requirement for American business. Because utilities are among the organizations with the most at stake in a carbon-constrained economy, they should proactively tackle carbon management and carbon accounting in spite of uncertainties about the precise formulation of the final regulatory framework. In short, whether a carbon accounting requirement is legislative, administrative, or driven by business partners and consumers, now is the time for utilities to act.

  • Operation of World’s First Supercritical CFB Steam Generator Begins in Poland

    The world’s first supercritical circulating fluidized-bed (CFB) steam generator began successful operation at the Lagisza power plant in Poland early this July, according to power equipment and engineering firm Foster Wheeler. The new CFB — believed to be the world’s largest — replaced 1960s-era pulverized coal units at the power plant owned by Polish utility […]

  • Energy Efficient Refrigerant Dryers

    Industrial productivity solutions provider Atlas Copco Compressors introduced a new generation of integrated refrigerant dryers for use with the company’s GA, GA+, and GA variable-speed drive 50 to 125 hp oil-injected screw compressors. Compared to conventional dryers with similar cooling capacity, the new R410A refrigerant dryers (ID 95-285) reduce direct power consumption by up to […]

  • Avoid These 10 Mistakes When Selecting Your New Water Treatment System

    There are a number of reasons why your plant might be looking at new water pretreatment equipment in the near future. One common reason is the addition of new generating capacity. Regardless of the type of new generation, you can be sure that it will require additional high-purity water for processes ranging from direct steam generation to power augmentation, NOx control, and washing the blades of the combustion turbines.

  • Oxygen and Combustibles Transmitter for Coal-Fired Applications

  • Top Plants: Edward W. Clark Generating Station, Clark County, Nevada

    The Edward W. Clark Generating Station, which has supplied electricity to the Las Vegas Strip for more than half a century, has learned the secret of life in the desert: adaptability. The plant’s early years featured conventional steam plants operated around the clock. By mid-life, Clark had been upgraded with two combustion turbine combined-cycle power blocks operated as intermediate-load resource. Today, the old steam plants have been replaced with fast-start peaking gas turbines.
