A new compact electric pump designed for bolt tensioning applications in the wind turbine industry is now available from specialist bolt tensioner manufacturer Boltight Ltd. The standalone power pack is lightweight (19.5 kg) and portable, as the pump, reservoir, and motor are combined into one easily handled package. The 0.75-kW rated pump is driven by a 220-240 V single-phase electric […]

Solid oxide fuel cells (SOFCs), which oxidize a fuel to produce electricity, have received much attention of late for the technology’s myriad benefits, including high efficiency, long-term stability, fuel flexibility, and low carbon emissions—all at a relatively low cost.

A three-judge panel of the U.S. Court of Appeals for the D.C. Circuit on June 26 unanimously rejected all pending legal challenges against the U.S. Environmental Protection Agency’s (EPA’s) interpretation of the Clean Air Act (CAA) that allows the agency to regulate greenhouse gases (GHGs). What is the EPA’s future strategy in its war on coal?

Endress+Hauser released the Proline t-mass 150 thermal mass flowmeter for measuring gases such as compressed air, nitrogen, carbon dioxide, and argon. The flowmeter measures mass flow, gas temperature, free air delivery, and corrected volume—all without the need for pressure or temperature compensation. The t-mass 150, with its high turndown of 100:1, can reliably measure small […]

Siemens Energy in June announced it had produced the first batch of its new B75 Quantum wind turbine rotor blades, fiberglass components 75 meters (m) in length that were cast in one piece (Figure 3). The blades were manufactured to be installed this fall on Siemens’ second prototype of the German firm’s SWT-6.0 6-MW offshore […]

Hach Co.’s new DR 6000UV-Vis spectrophotometer was designed to fulfill any water testing needs using one spectrophotometer. It is equipped with RFID technology, integrated QA software, and more than 250 testing methods and guided procedures. The instrument is programmed to take absorbance readings of a single sample at different wavelengths or over a specific period […]

Albania this June inaugurated its first major hydropower project since the early 1980s, bringing online Ashta I, the first of two run-of-river plants with a combined capacity of 53 MW. At the inauguration ceremony, Albania’s Prime Minister Sali Berisha called the plant “a novelty” because it is the largest in the world to use advanced tubular turbines technology.

The U.S. Environmental Protection Agency (EPA) has a long history of making waves with the electric power industry because of its efforts to regulate the way thermal power plants construct and operate their cooling water intake structures (CWIS). These structures divert billions of gallons of water into power plants’ cooling systems and can injure or kill billions of aquatic organisms.

A new gas-fired power generation technology that uses an oxyfuel, high-pressure, supercritical carbon dioxide cycle and produces pipeline-ready carbon dioxide for sequestration or use in enhanced oil recovery (EOR), without reducing plant efficiency, garnered the interest of three new partners in June.

FP&L to Increase Output at Turkey Point. Florida Power & Light (FP&L) on June 19 received approval from the Nuclear Regulatory Commission to increase the power generating capacity of Turkey Point Nuclear Generating Units 3 and 4 by 15%. The power uprate for the pressurized water reactors will increase each unit’s capacity from approximately 700 […]
