  • Rethinking the Power Industry’s Dash to Gas

    During a recent meeting of state utility commissioners, the CEO of a Fortune 500 electric power company said natural gas prices promise reliability but "always break your heart." What breaks my heart is the electric power industry’s ongoing love affair with natural gas. Using natural gas for generating electricity is not the best or highest use for this clean, green, and domestically abundant resource.

  • U.S. Spins Nuclear Wheels as Other Nations Roll Out New Plants

    President Barack Obama’s January State of the Union speech called for incentives to make clean energy profitable — mainly through the construction of a new generation of nuclear power plants. That comment, an apparent effort to reach out to Republican members of Congress, drew furious applause. Within three weeks, the president’s backing of nuclear power had already made a significant impact on the U.S. nuclear sector.

  • Initial Experiments Meet Requirements for Fusion Ignition

    Scientists at Lawrence Livermore National Laboratory’s National Ignition Facility (NIF) in California speculate that a prototype nuclear fusion power plant could be operational within a decade, thanks to a test of the world’s largest laser array that confirmed a technique called inertial fusion ignition is feasible. Their first experiments have demonstrated a unique physics effect that bodes well for NIF’s success in generating a self-sustaining nuclear fusion reaction. Fusion energy is what powers the sun and stars.

  • From GHG to Useful Materials

    Could the transformation of carbon dioxide (CO2) into carbonates and oxides solve the problem of greenhouse gas emissions (GHG) from fossil-fired power plants? Some companies are betting that such processes could make everyone happy and even create new profits. Buzz has been growing about this approach, though the concept has been around for many years.

  • Marines Get Power from Waves

    Ocean Power Technologies Inc. (OPT) announced on Feb. 1 that it had successfully deployed one of its PowerBuoy wave energy devices about a mile offshore from a U.S. Marine Corps Base on the island of Oahu in Hawaii. The device generates up to 40 kW of power from the rise and fall of waves, and since its deployment in December 2009, it has been generating power within specifications.

  • Permeable UK Granite Is Good News for Geothermal Energy

    In mid-February, the Geological Society of London raised the hopes of those promoting geothermal energy when results of exploratory drilling in Weardale, County Durham, revealed record levels of permeability in granite. Although the results are promising for the development of geothermal energy, they may have less welcome implications for the safe disposal of radioactive waste in deep repositories.

  • Dish Stirling Solar Plant Debuts

    In late January, a 1.5-MW concentrating solar power (CSP) plant began providing power to Salt River Project customers in Greater Phoenix, Ariz. Though small, the plant, developed by Tessera Solar and Stirling Energy Systems (SES), is seen as a prelude to 1,500-MW projects that are due to break ground in California and Texas later this year.

  • Deciphering Desuperheater Failures

    The "combined" portion of a combined-cycle plant is the heat-recovery steam generator (HRSG) that generates high-pressure and high-temperature steam and the steam turbine generator that expands the steam to produce electricity. Integrating the HRSG and steam turbine with the combustion turbine is a key challenge for plant designers, as each system has differing operating profiles, operational constraints, and design requirements.

  • Stainless Triplex Plunger Pumps

    CAT PUMPS recently introduced two new stainless steel triplex plunger pumps featuring a 316 stainless steel liquid-end for corrosion resistance. The 7CP6111 and 7CP6171 are designed for pumping liquids like seawater in small seawater reverse osmosis installations, demineralized water for misting, or hot water and sanitizers for sterile cleaning systems. The 7CP stainless steel pumps […]

  • Microprocessor-Based Vibration Amplifier

    Sensing and monitoring systems supplier Meggitt PLC launched the Endevco model 6634C, a microprocessor-based vibration amplifier that has been designed to condition and display rotating machinery data in simultaneous outputs, such as broadband, acceleration, velocity, and displacement. Model 6634C is designed to accept inputs from a single-ended, differential piezoelectric or ISOTRON (IEPE-type) accelerometer, velocity coil, […]
