Faced with roadblocks to reducing greenhouse gas emissions via globally meaningful regulations or carbon pricing schemes, some scientists say it’s time to consider even more drastic human intervention. As it looks increasingly unlikely that the world will adopt a political and economic approach to reducing greenhouse gas emissions—primarily carbon dioxide—what was once regarded as a […]

Temporary power may be the most widely distributed “distributed” generation worldwide, and its distribution is spreading, thanks to its ability to quickly meet urgent needs not only for event, construction, and post-disaster emergency power but also for fast-growing economies and stressed grids. That’s making it a serious competitor for “permanent” power in some situations. When […]

The Springerville Generating Station has been a work in progress since the first unit entered service in 1985. The PRBCUG recently recognized Springerville with its 2014 Plant of the Year award for implementing industry best practices, continual improvements, and worker safety.  The presentation of the Powder River Basin Coal Users’ Group (PRBCUG) Plant of the […]

Once touted as the savior of coal power and the future of clean coal generation, integrated gasification combined cycle (IGCC) technology has seen its prospects swamped by soaring costs and technological challenges. Though it remains controversial, its proponents are not ready to give up. If you’re an energy sector observer with an interest in integrated […]

Though our current power grid is more sophisticated and reliable than when Thomas Edison designed it nearly a century ago, it uses the same model: A company burns fuel to create electricity, which is then sent hundreds of miles along inefficient wires to customers who are given a single energy choice: on or off. Now, […]

The world’s first floating wind turbine array could be installed offshore of northeast Scotland by 2017 if a project recently unveiled by Kincardine Offshore Windfarm Ltd. proceeds as planned. The joint project between Pilot Offshore Renewables and the construction giant Atkins entails the installation of eight turbines on semi-submersible platforms about 8 miles off the […]

Last year, the U.S. exported nearly twice the amount of wood pellets it sent overseas in 2012—and almost all of it went to Europe for heat and power needs. This trend has gained momentum since 2009, when the European Commission (EC) enacted its 2020 climate and energy package, and will possibly continue in the long […]

Chile Banks on Renewable Capacity Expansion, Energy Efficiency. Chile in mid-May released a $650 million investment plan to reduce energy costs and promote non-hydro renewable energy development for the country that imports about 60% of its primary energy resources. The plan calls for a 30% cut in marginal power costs on Chile’s central grid, which […]

One of the world’s first grid-scale iron-chromium redox flow batteries was interconnected this May to the distribution grid. The EnerVault Turlock, which its developer EnerVault says is a 250-kW, 1-MWh battery grid-scale energy storage system, will be charged by a 150-kW dual-axis tracking solar photovoltaic system in an almond orchard in California’s Central Valley, will […]

The most contentious (though not necessarily the most expensive) proposed environmental regulation to hit the power industry in this century was released by the Environmental Protection Agency (EPA) on June 2. The most immediate consequence was an increase in the volume of email. The Big One As I write this column a week after the […]

China, the world’s biggest emitter of greenhouse gases (GHGs) could limit its total carbon dioxide (CO2) emissions for the first time, possibly starting in 2016. He Jiankun, chairman of China’s Advisory Committee on Climate Change, reportedly told conference attendees in Beijing in June—one day after the U.S. Environmental Protection Agency proposed rules to slash carbon […]

Sure, the Nest Learning Thermostat is smart, user-friendly, and downright sexy, but at $249, it’s more a luxury item than a mass-market appliance. Indeed, Nest thermostats are highlighted in upscale real estate listings alongside marble countertops and stainless steel appliances. Although Nest has done well since its debut in 2011, with almost a million units […]

Though no single mercury capture approach is best for all plants, when you can capture two (or more) pollutants with one sorbent, it’s worth a careful look.  The U.S. Environmental Protection Agency’s (EPA’s) Utility Mercury and Air Toxics Standards (MATS) regulation requires power plants to reduce emissions of hazardous air pollutants (HAPs), including mercury. The […]

Eddy currents are electrical currents induced within conductors by changing magnetic fields. They are commonly used in nondestructive evaluation (NDE) and corrosion monitoring of structures with painted surfaces. The work of eddy current technicians, who specialize in the electromagnetic modality, requires a high degree of accuracy even when working under challenging testing conditions. Traditionally, technicians relied on […]

With quickly approaching deadlines for achieving renewable portfolio standard goals, the likely lapse of a critical exemption this month may increase the challenges for meeting those mandates. Approximately four years ago the U.S. Environmental Protection Agency (EPA) took the first step in regulating greenhouse gas (GHG) emissions from electric generating units (EGUs) by promulgating the […]

It has been more than two and a half years since the Environmental Protection Agency (EPA) issued national emission standards for hazardous air pollutants from coal- and oil-fired electric utility steam generating units (EGUs), and standards of performance for fossil fuel–fired electric utility, industrial/commercial/institutional, and small industrial/commercial/institutional steam generating units. Specifically, the rule created mercury […]

Power plant operators have long understood the vital role water plays in power generation. Now, as the rest of the world begins recognizing that as well, a conflict is brewing between the growing demand for electricity and increasingly strained water resources. Unless you’ve been living in a cave, you’ve likely heard the term “water-energy nexus” […]

South Africa’s critical power situation has been the subject of much talk and speculation since 2008, when the country experienced its first electricity crisis after enjoying a surplus of cheap electrcity since the 1980’s. Download the report.

Construction of China’s first high-temperature gas-cooled reactor (HTR) demonstration plant kicked off this April after pouring of concrete for the basemat of the Generation IV reactor was completed. Though

All power plants must continually strive to control operating expenses, but it is particularly important for coal-fired facilities to cut costs these days to stay competitive while meeting ever-more-stringent

New rules adopted by the European Commission (EC) in April will gradually phase out renewable energy subsidies that currently bolster the European Union’s (EU’s) €48-billion-a-year clean energy

All states were not created equal, particularly when it comes to indigenous reserves of fossil fuels. North Dakota is experiencing a boom in oil production, which has increased almost 10-fold since 2005, and

Australia Releases Emissions Reduction Fund White Paper. Australia’s Ministry of Environment on April 24 released its Emissions Reduction Fund (ERF) White Paper, formally setting out the final design of the

It is an exciting time to be a part of the energy industry. New technology is being developed in almost every sector of the business. The coal industry is working on carbon capture and storage solutions

The interlinkages between water and energy are complex and run deep, warns a United Nations (UN) World Water Development water and energy–themed report released this March. As global water demand (in terms
