Varnish buildup in oil systems and components can degrade performance and cause erratic valve operation. Some experts have conducted research and formulated new lubricants that could help solve those problems. One such oil proved highly successful during a five-year run at a gas turbine power plant. By eliminating the need for oil changes and valve […]

The U.S. should capitalize on China’s formidable experience to put its own domestic solar power sector on a more “economically sensible” path, researchers from Stanford University said in a new report. The March 21–released report, “The New Solar System,” which was funded by a research grant from the U.S. Department of Energy (DOE), offers a […]

Crippled by financial setbacks stemming from the half-built AP1000 reactor projects in Georgia and South Carolina, Westinghouse Electric Co., a company with a storied legacy symbolic of American nuclear power, has taken the desperate step of filing for bankruptcy protection. While owners of the two nuclear construction projects are monitoring the situation, the development could […]

Siemens has installed the prototype of its towering 8-MW offshore direct-drive wind turbine at a national test center in Østerild, Denmark, marking the company’s foray into the global race to develop mega–wind turbines. The new offshore turbine was installed on a steel tower at a hub height of 120 meters (m) in late January (Figure […]

Construction of four AP1000 units—the first new nuclear reactors in the U.S. in decades—is moving along at Vogtle 3 and 4 in Georgia and at the V.C. Summer nuclear power plant in South Carolina. In January, Westinghouse, which is spearheading construction of the units, marked a key milestone as it placed the first steam generator […]

Stricken by falling prices, producers of liquefied natural gas (LNG) are looking to exploit an emerging trend that integrates the fuel source with power generation. According to Houston-based international law firm Baker Botts, an increasing number of LNG power projects are emerging worldwide as a “new, viable medium” that offers a rapid but long-term power […]

The Hawaiian Electric Co. (HECO) and technology service company Stem Inc. have successfully tested nearly 1 MW of energy storage systems at 29 commercial sites on Oahu, the companies said on January 30. The novel pilot project, which sought “the ability to connect many customers’ energy storage with the utility,” comprises an energy storage “fleet” […]

Eddy current testing is a well-established method of nondestructive testing that is used to examine nonferrous/nonmagnetic materials such as condenser and heat exchanger tubes in power generation plants. Eddy current testing reveals discontinuities in tubing, provides plant engineers with an accurate assessment of a unit’s condition, and is a tool for predicting the remaining useful […]

Society is highly reliant on the safety and stability of critical infrastructure. From boiling a kettle to maintaining national security, an interruption in the electricity supply can cause serious damage to

Many informative articles have been published about options for treating flue gas desulfurization wastewater, but new technologies are rapidly changing the treatment possibilities. This article reviews key economic considerations and introduces an innovative treatment solution that lowers costs and the amount of waste generated. Flue gas desulfurization (FGD) wastewater varies widely depending on the source […]

Using reclaimed water as a makeup supply for cooling tower systems has become a popular option for reducing impacts on local water resources, but it comes with its own challenges because of its unique

Southern Co.’s Kemper County integrated gasification combined cycle (IGCC) project, stricken by steep cost increases and an in-service date delayed again to mid-March, isn’t economically viable in the face of projected long-term natural gas prices, the company said. Southern Co. subsidiary Mississippi Power reported that integrated operation of the facility’s two gasifiers and combustion turbines […]

Remote and online monitoring of plant performance parameters is an important step toward a fully connected plant, but alone it’s not enough to exploit the real value in the Industrial Internet of Things, speakers at POWER’s inaugural Connected Plant Conference on February 15 in Dallas said. Randy Bickford, president and CTO of software firm Expert […]

A variety of approaches have been used to capture new benefits from combined heat and power (CHP) facilities. Some owners have transitioned to new fuels or added renewables to the mix, while others have implemented unique business models to spur development. As district heating systems are brought into the 21st century, the CHP sector seems […]

A wastewater treatment plant in the Danish city of Aarhus is reportedly producing enough power to cover all of the energy used for the whole water cycle in its catchment area—from water production and water

Combined heat and power (CHP) has long been a popular option for industrial self-generation, but new technologies and business partnerships are taking the sector well beyond the traditional boilers and diesel gensets. The Erving Paper Mill in the western Massachusetts town of the same name has operated for more than 100 years. Once part of […]

NuScale will submit the nation’s first application for design certification of a small modular reactor (SMR) to the Nuclear Regulatory Commission (NRC) on Thursday.
