There are many reasons to anticipate that the use of wireless instrumentation in industrial settings will increase dramatically in the next few years.

Robotic Torches for Single Arc, Tandem Applications ESAB Welding & Cutting Products launched the new Aristo RT line of robotic torches, designed for single arc or tandem applications. The Aristo RT range of robotic torches work with three different product setups: Standard (external cable), Hollow Wrist Helix (rotation +/–220o), and Hollow Wrist Infiniturn (endless rotation). […]

The transformative increases in current and expected future domestic natural gas production have spawned yet another energy debate: Should the U.S. should export natural gas?

In communities all across North America, environmental justice (EJ), which calls for the fair treatment of all people, including those of color and the economically deprived, remains a serious concern.

Drought and competing uses for water continue to challenge power plant operators worldwide. In response, innovative approaches for reducing water use are being explored from South Africa to China.

Even though it enjoys sizeable coal and natural gas reserves, Indonesia struggles to provide electricity to its growing economy. Geography is its most obvious challenge. Others include evolving international markets and an energy sector that remains highly politicized.

Recent studies have shown that system oxidation-reduction potential (ORP) is not only an important factor for predicting wet flue gas desulfurization (WFGD) absorber chemistry but also may be a predictor of process equipment corrosion and wastewater treatment requirements.

A vital part of any coal-fired unit is its fuel delivery system (FDS). A newly formed subcommittee of the ASME Research Committee on Energy, Environment, and Waste has investigated potential FDS upgrades on three typical 500-MW wall-, tangential-, and cyclone-fired boilers. The subcommittee has produced a series of suggested upgrades that have a simple payback of no more than two years.

The electricity grid has been characterized as the world’s largest and most complicated machine. The grid, like all machines, requires periodic upgrades and maintenance to prevent outages during the normal course of business, and it can be brought down by various outside forces. Solar flares and cyber attacks have temporarily crippled the machine, but an electromagnetic pulse event would be the “ultimate cyber security catastrophe.”

Beacon Power Corp. was founded in 1997 to develop flywheel-based energy storage technology. By 2007, the 100-kW/25-kWh Gen 4 flywheel system was commercialized and deployed in several projects. However, market conditions pushed the company into bankruptcy in late 2011. The company has since emerged, reinvigorated with new investment and a new name: Beacon Power LLC.
