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. The Corvallis, Ore.–based company, which is majority owned by the Fluor Corp., has been developing its light-water reactor nuclear technology for more than 15 years. Development of the NuScale power module […]

Petra Nova—a commercial-scale post-combustion carbon capture project designed to remove more than 90% of the carbon dioxide (CO2) from a 240-MW slipstream of flue gas off of the W.A. Parish generating station in Fort Bend County, Texas—has been completed, according to project partners NRG Energy Inc. and JX Nippon Oil & Gas Exploration Corp. The […]

Beyond major reliability events that have prompted regional blackouts in the past, the U.S. grid faces “imminent danger from cyber attacks,” warns the second installation of the Obama administration’s Quadrennial Energy Review (QER). Here are other key trends outlined in the comprehensive study of the nation’s electricity system. The QER, available on the DOE web site, identifies the threats, […]

A digital roundtable with four senior members of diverse generating companies reveals that regulations aren’t the top concern at the moment. Instead, decisions are being driven both by customer desires and

Background burner control is critical for power and industrial plants because it affects emissions, energy costs, and process efficiencies. For natural gas burners, variations in gas composition can have a

A tumultuous election year that was marked by market turmoil, the events of 2016 clearly showed that big change is afoot for the power sector. Many of POWER‘s bold predictions for 2016, such as that the near-simultaneous surge in U.S. natural gas production and recent enactment of environmental rules would reshape the U.S. power sector, […]

A joint strategy released by the governments of the U.S. and Canada to thwart the growing threat of cyberattacks on the electric grid sets three priorities that the countries said would be critical to preserving energy and national security. The “Joint United States-Canada Electric Grid Security and Resilience Strategy,” released on December 15, outlines three […]

President-elect Donald Trump has picked former Texas governor Rick Perry to be his energy secretary

Global demand for the 17 periodic table elements—15 within the chemical group called lanthanides, plus yttrium and scandium—has soared in recent years as they become increasingly integrated in new technologies. Some major end uses include generators for wind turbines, permanent magnets and rechargeable batteries for hybrid and electric vehicles, automotive catalytic converters, fluid cracking catalysts […]

Meeting in Marrakesh, Morocco, during the most recent United Nations climate change conference (COP22), Mission Innovation countries—a group of nations whose stated mission is to accelerate the pace of clean energy innovation—launched seven innovation challenges, designed as a global call to action for the research community, industry, and investors. The challenges are: Smart Grids Off-Grid […]

“We’re at a very challenging time,” said former Federal Energy Regulatory Commission (FERC) Commissioner Tony Clark at the annual meeting of the National Association of Regulatory Utility Commissioners (NARUC) on November 14. We have a “need for infrastructure, but it’s more difficult to get it sited and built than ever before.” Clark’s comment, which he […]

While GE-Hitachi Global Laser Enrichment (GLE) confirmed it hasn’t made a formal decision to proceed with licensing or construction of a laser enrichment facility at Paducah, Ky., the Department of Energy (DOE) announced it has agreed to sell depleted uranium to the company over a 40-year period to help produce nuclear power plant fuel. The […]

Russia and China have agreed to expand cooperation on nuclear energy, with Russia to build another two reactors in China in addition to expanding cooperation on fast-reactor technology and floating nuclear plants, Russia’s state-owned nuclear firm Rosatom said in a November 8 statement. The two nations, which share a 4,200-kilometer-long border, have worked together on […]

GE-HItachi Nuclear Energy (GEH) and Southern Nuclear Energy will collaborate to study the development and licensing of GEH’s PRISM sodium-cooled fast reactor design.

Although many observers consider Elon Musk—the visionary entrepreneur who leads Tesla Motors and SpaceX—to be a disruptive force threatening the conventional power industry, he believes power companies have a bright future, if his goal to expand the use of electric cars and install vast numbers of rooftop solar systems is achieved. Speaking during a presentation […]

Compliance with one of the latest federal environmental regulations, the Effluent Limitations Guidelines (ELG), can be both costly and complicated. A newly available option offers features and capabilities that may make it a more attractive alternative than conventional approaches. In September 2015, the U.S. Environmental Protection Agency (EPA) finalized a new rule affecting flue gas […]

To power generation professionals, the word “cavitation” typically has negative connotations, but a new process offers a way to control this normally destructive effect and deploy it as a cost-effective life-extension technique. As operators of commercial nuclear energy facilities consider subsequent license renewals and life extensions, finding new ways to safely maintain reactor components remains […]
