MHI to Continue Pre-Construction Work for North Anna Unit. Mitsubishi Heavy Industries Ltd. (MHI), through Mitsubishi Nuclear Energy Systems Inc., and Dominion subsidiary Virginia Electric and Power Co. on Dec. 27 said they had reached an agreement to continue pre-construction, engineering, and planning work in preparation for a third unit at Dominion’s North Anna Nuclear […]

Researchers at Germany’s Technische Universitaet Muenchen (TUM) claim to have developed a small-scale hydroelectric power plant that is capable of operating profitably even at modest dam heights while minimizing impact on waterways.

Dr. Michael Weinhold, chief technology officer of Siemens Energy, discusses the company’s 2011 business plans and the role of the smart grid in the future’s energy infrastructure.

It’s time to pull my crystal ball out of storage, polish it up, and give you another round of U.S. industry predictions for 2011. I graded last year’s predictions B+ (for a complete rundown of how I graded each prediction, see page 32), but I’m convinced I’ll do better in 2011.

For more than a decade Babcock & Wilcox Power Generation Group Inc. and Air Liquide have been developing oxyfuel technology with the goal of using it to concentrate CO₂ from pulverized coal-fired power plants and achieve up to 90% CO₂ capture and storage. This technology was recently selected for demonstration as part of FutureGen 2.0.

Though electricity generation has entered a key period of transition—as investment shifts to low-carbon technologies—world electricity demand is set to grow faster than any other “final form of energy,” the International Energy Agency (IEA) says in its latest annual World Energy Outlook.

The new Oil Eater all-in-one professional grade emergency spill kits are designed to contain and clean up hazardous spills as required by the U.S. Occupational Safety and Health Administration and the Environmental Protection Agency. Each kit contains absorbent pads, pillows, universal snakes, booms, protective gloves, oil-resistant and high-temperature disposal bags, and an emergency response instruction […]

China in mid-November embarked upon building the first massive hydropower project in Tibet, a 6 x 85-MW plant straddling the middle reaches of the mighty Yarlung Tsangpo River (Figure 2). According to the Hunan Daily, a Chinese state-owned enterprise, Sinohydro began damming the river in Shannan Prefecture, Tibet, on Nov. 8, kicking off the 7.9 billion yuan ($1.2 billion) “run of the river” project that is estimated to generate electricity for the surrounding region by 2014.

Voith Turbo H + L Hydraulic’s hydraulic Closed Loop Differential Pump (CLDP) linear axis can be used for all direct linear movements—especially for applications that rely on dynamics, reproducibility, overload protection, and reliability. Compact, highly dynamic, and precise, the linear drive offers overload protection, high power density, and virtually wear-free operation. At its heart is an integrated […]

Mitsubishi Heavy Industries (MHI) has begun converting a combined-cycle plant in Japan to prepare for verification testing of its long-anticipated J-Series gas turbine in February 2011—a system that the company claims has the most power generation capacity and highest thermal efficiency in the 1,600C turbine inlet temperature class (Figure 3). The work being carried out at the Takasago Machinery Works facility in Hyogo Prefecture (where the company’s G-Series gas turbines were tested) includes installation of the J-Series turbine, and it marks another major milestone in the technology’s development.
