Congress snubbed the biomass power industry in 2004 when open-loop biomass power plants were given only half the production tax credits (PTCs) received by other renewable sources, such as wind, solar, and geothermal. It further dissed open-loop biomass plants by authorizing the credit for only five years (it expired December 31, 2009) rather than the 10 years given to other renewables. Why is the biomass power industry not getting the policy respect and equity with other renewable technologies that it deserves?

Acknowledging that ANSI centrifugal pumps often need to be installed in areas where space is at a premium, Griswold Pump Co. has developed the 811CC (Close Coupled) ANSI centrifugal pump. This pump offers the features and flexibility of standard Griswold 811 ANSI pumps but with a smaller electrical motor encased in a compact package. Despite […]

CHLOR*RID International launched the Chlor*Ion Meter, a handheld digital testing device that electronically measures chloride on surfaces with an internal ion-specific electrode. Most surface chloride testing devices offer an external electrode on a cord, but these could be damaged in the field, CHLOR*RID says. Because it digitally measures chloride on surfaces, the Chlor*Ion Meter’s ion […]

Bernard’s new customizable W-series water-cooled MIG guns and water-cooled Centerfire consumables are designed to meet the wide-ranging needs of high-amperage, water-cooled metal inert gas (MIG) applications. The W-Guns (shown here) are durable and may be customized. Users can choose neck styles, cable lengths, handle styles, consumables, and direct plugs. The W-Guns are rated to 600 […]

Building and engineering software designer Autodesk Inc. announced the availability of AutoCAD Plant 3D 2010, a product that it says brings the benefits of model-based design to mainstream plant design projects. The vast majority of plant design and engineering projects support the operation, maintenance, and expansion of existing facilities. These projects are typically executed by […]

LUDECA’s new CENTRALIGN ULTRA was specifically developed for the alignment of steam and gas turbines. The system precisely aligns internal elements with upper halves for distances up to 133 feet. Accurate bore measurements can be acquired and wirelessly transmitted without interrupting other processes, saving time over traditional methods like piano wires, micrometers, and optical instruments. […]

ESAB Welding & Cutting Products launched the TAF 801/1251 square wave AC power sources for submerged arc welding. The power sources, designed to be used with the fully digital PEK controller, convert the secondary voltage from a sinus wave — via a thyristor-controlled rectifier bridge — to a square wave arc voltage with excellent arc […]

The first six of a dozen high-capacity turbines were commissioned in mid-December at the 60-MW Alpha Ventus project in the North Sea, Germany’s first offshore wind park. All 12 turbines of the €250 million project are already standing, put up in just seven months by a consortium of EWE, E.ON, and Vattenfall — formally known as Deutsche Offshore Testfeld und Infrastruktur (DOTI).

More than 60 floating power stations are in operation around the world, deploying some 4 GW at continental shores where electricity is most needed. Though these feature a variety of power sources (including nuclear, gas, and heavy fuels), most are power barges — they do not have their own propulsion systems and would have to be towed to desired locations.

High-voltage direct current transmission (HVDC) has come a long way since 1882 when the first of its type carried power from Miesbach in Bavaria to an electricity exhibition in Munich, 57 kilometers (km) away, at a mere 1,400 V. Last December, just before the world ushered in the new decade, Siemens Energy and grid operator China Southern Power Grid put into operation the first pole of a transmission link between the southern Chinese provinces of Yunnan and Guangdong, a 1,418-km ultra-high-voltage direct current (UHVDC) system. That line has a transmission capacity of 5 GW, and it operates at a voltage of 800 kilovolts (kV) — a world record.
