An unnamed power company and the U.S. Naval Research Laboratory (NRL) have partnered to test a concept proven to work at a small scale that applies pulsed electron beam technology to slash coal plant nitric oxide and nitrogen dioxide (NOx) emissions. The concept (Figure 3) essentially involves directing electron beams from a cathode into the […]

The long-drawn-out political impasse on Australia’s review of its Renewable Energy Target (RET) has generators reeling from what they say are “constant policy changes and distortions from successive interference by governments.” Australia’s RET, which has been in operation since 2001, was increased in 2010 to require that about 20% of the nation’s then-projected demand in […]

As it struggles to grow its economy while improving air quality in urban areas, China is updating its energy delivery infrastructure. A key part of that plan is switching from coal-fired to gas-fired combined heat and power plants. To push efficiency even further, some plants are turning to synchronous clutches. The developed world has done […]

A combination of spent fuel pools reaching capacity, security concerns, and mostly nonexistent policies regarding long-term consolidated storage of nuclear waste is making dry cask storage the only way forward for most nations with nuclear power reactors. Around the world, demand for dry cask storage facilities for spent nuclear fuel (SNF) is on the rise. […]

An increasing supply of low-cost higher-chlorine coal is prompting many U.S. generators to give the fuel serious consideration in spite of its reputation for causing corrosion. Though corrosion can be a consideration, it’s not always caused simply by the fuel switch. Understanding the various chemical interactions, as well as operational and emissions pros and cons, […]

More than six and a half years after the Department of Energy (DOE) submitted its license application seeking authorization to build a geologic repository, Nuclear Regulatory Commission (NRC) staff published the final two volumes of the safety evaluation report (SER) on the Yucca Mountain site. Released on Jan. 29, Volume 2 covers repository safety before […]

According to a study funded in part by the U.S. Department of Energy (DOE) and conducted by Massachusetts Institute of Technology (MIT) researchers, a smaller portion of carbon dioxide (CO2) that is injected into the ground may be converted into rock than was previously presumed. The team, working in the Department of Earth, Atmospheric and […]

President Obama’s State of the Union (SOTU) address on Tuesday night held no surprises about energy issues. The word “energy” only appeared twice in the president’s speech—once in mention of the nation’s “booming energy production” and once with regard to how we produce and use energy. The word “power” came up twice with respect to […]

Continuing a drive to reduce its energy intensity 16% between 2010 and 2015, China’s State Council announced on Jan. 20 that the country had managed a 4.8% reduction in 2014, beating the target of 3.9%. Energy intensity is a measure of a nation’s efficiency in using energy to drive growth in gross domestic product (GDP). […]

On Jan. 14, the Environmental Protection Agency (EPA) published its Toxics Release Inventory (TRI) report for 2013 showing that electric utilities have cut toxic releases to the environment 49% since 2003. The drop was driven by a 73% decline in on-site toxic air releases as a result of a decrease in hazardous air pollutants (HAP) […]
