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.

Panelists at the ELECTRIC POWER 2013 Keynote and Roundtable Discussion in Chicago in May were consumed by the need to ensure future reliability by more closely integrating the gas and electricity markets. Acknowledged less directly were distortions created by renewable energy subsidies and mandates, onerous regulations affecting coal, and “irreversible” demand destruction caused by the success of energy efficiency and demand management programs. The elephant in the room was the continued demise of electricity markets.

Last month’s column, “Opinions à la Carte,” prompted an unusually high number of emails from readers. Unexpectedly, the responses to the different format were universally favorable.

With ever-increasing demands for fast ramping and flexibility, natural gas–fired plants are grabbing a bigger share of the generation pie. But uncertainty about future prices and concerns about overreliance on a single fuel are dampening enthusiasm during what may be the most exciting time for gas ever. Natural gas is hot—but will generators and the market get burned?

Water scarcity as it relates to energy use is becoming a major concern.

With the country awash in natural gas and new construction dominated by gas-fired plants, one would think that integrating these plants into the grid would be simple. Like politics, integration problems appear to be local.

Energy policy in the European Union (EU) is in upheaval as concerns mount over the impact of energy costs on the competitiveness of the power industry.

It’s easy to see why technologists fall in love with high-temperature gas-cooled reactors (HTGRs). These nuclear machines are remarkable inventions, at least on paper. But few have actually seen the real world for any length of time, and their real-world experience has been mixed.

President Barack Obama’s landmark speech on Tuesday outlining executive actions to combat and prepare for climate change backed the growth of natural gas and renewable power in lieu of carbon-heavy coal power, but he mentioned nuclear power only once—and only in the context of energy security.

Amid the deluge of reactions to President Obama’s June 25 speech announcing wide-ranging executive actions to curb carbon emissions and prepare for climate change effects were some unexpected statements.

An update to the Final Supplemental Environmental Impact Statement (FSEIS) issued by the Nuclear Regulatory Commission (NRC) on Tuesday finds that possible impacts on aquatic life from the Indian Point nuclear power plant in New York still do not bar it from receiving a license renewal.

Driven by the booming growth of generation from hydro, wind, and solar photovoltaics (PV), generation from renewables on a terawatt-hour basis is set to surpass that from natural gas and double nuclear’s share by 2016, becoming the world’s second-most important global electricity source after coal, according to a new report from the International Energy Agency (IEA).

The U.S. has least 3,000 metric gigatons (Gt) of subsurface carbon dioxide storage capacity that is technically accessible below onshore areas and state waters—500 times more than previously estimated—the U.S. Geological Survey (USGS) suggests in a new assessment released on Wednesday.

The Supreme Court today granted a petition by health and environmental groups, 15 states, and the Environmental Protection Agency (EPA) and agreed to review the Cross-State Air Pollution Rule (CSAPR), a Bush-era rule that a federal appeals court had previously vacated.

President Obama’s highly anticipated Climate Action Plan (CAP) released today outlines a wide variety of executive actions founded on three pillars: slashing U.S. carbon pollution through stringent rules for new and existing power plants while doubling renewables deployment and promoting fuel switching from coal to natural gas; preparing the U.S. for impacts of climate change; and leading international efforts to combat global climate change.

By Gail Reitenbach Santa Fe, N.M., June 26, 2013 — If you’re looking for an example of just how complex—and critical—the challenge of reducing greenhouse gas (GHG) emissions and mitigating the effects of climate change can be, look west. Those involved in the power generation industry are understandably focused on a single element of President […]

By Kennedy Maize Washington, D.C., June 25, 2013 – In many ways, what is not in the plan that President Obama rolled out at his (not open to the public) speech at Georgetown University today is as interesting as what is in it. Many have noted the absence of references to the pending decision on […]

States Stall on GHG Rule Suit on Anticipation of Major Climate Change Action
Litigation to force the Environmental Protection Agency (EPA) to issue final greenhouse gas (GHG) rules has been stalled on reports that the White House could soon announce major action on climate change.

The Tennessee Valley Authority (TVA) last week indefinitely delayed new construction on its Bellefonte Nuclear Plant in Alabama, saying it had slashed the project’s budget by 64% and would reduce staff by 75%.

In a marked energy policy shift away from a complete nuclear phase-out, Japan’s Nuclear Regulatory Authority (NRA) on Wednesday adopted new safety standards that Japan’s 48 shuttered nuclear reactors must meet before they can restart.

The fiscal year 2014 Energy and Water Appropriations Bill released by the U.S. House Appropriations Committee this week slashes $1.4 billion in funding to Department of Energy renewable energy and scientific research programs, including an 80% spending cut on the Advanced Research Projects Agency-Energy (ARPA-E) program.

The House Energy and Commerce Committee on Wednesday advanced a set of four bills that it said would "improve" environmental regulations and increase state authority, including legislation that would task states—not the Environmental Protection Agency (EPA)—with the responsibility to set up coal ash disposal rules.

Cape Wind, North America’s first offshore wind farm, got $200 million in conditional funding from a Danish pension fund on Tuesday to help it reach financial closure this year.
