Carbon capture and storage (CCS) has of late gained steam as the best way to mitigate emissions of the greenhouse gas carbon dioxide (CO2) from fossil fuel power plants, despite evidence that the approach would require much energy and increase the fuel needs of a coal-fired plant by more than 25%. A new study from […]

Congress should push for nuclear energy as a climate and energy solution—now.

Construction of the Portlands Energy Centre was a logistical dream: A mothballed power plant next door had an active switchyard, natural gas pipeline, and cooling water structure. The new facility put peak power into the Ontario Power Authority’s grid from its two combustion turbines only two years after collecting the necessary permits. The entire plant entered commercial service on April 23, 2009 — six weeks early.

Recent months brought several developments in Europe’s much-touted "nuclear renaissance." Spain Extends Life of Nation’s Oldest Reactor Spain’s government on July 2 granted a four-year extension to the operating permit of the 466-MW Santa María de Garoña nuclear power plant (Figure 3). The decision follows a nonbinding recommendation by Spain’s nuclear regulator in June to […]

There’s been a lot of attention on “cellulosic” ethanol, but that could be a nasty dead end, according to this analysis from a well-respected Washington environmental think tank.

Xcel Energy has completed the third and final project required by its 2003 Metropolitan Emissions Reduction Project agreement: repowering the Riverside Plant with a gas-fired 2 x 1 combined-cycle plant and tearing down the old coal-fired plant. Saved from demolition was the Unit 7 steam turbine system that now serves the new plant. Xcel staff expertly managed the project to an on-time start-up and accepted many important construction tasks, harkening back to the days when utilities took a more active role in the design and construction of projects.

The first aircraft designed to fly day and night propelled solely by solar energy was unveiled at Dübendorf airfield, Switzerland, in late June. The Solar Impulse has the wingspan of a Boeing 747-400 and the weight of an average family car (1,600 kg) (Figure 4). More than 12,000 solar cells mounted onto the wings will […]

U.S. wind power appears becalmed, partially stymied by transmission constraints, and also by financing difficulties in the current recession. Read the details.

At Royal Pride Holland’s commercial tomato greenhouse, green thumbs and green energy go hand in hand. With a total energy utilization of 95% in this application, GE’s new Jenbacher J624 natural gas – fired engines offer the innovative greenhouse an economical supply of on-site electrical and thermal power, as well as CO₂ fertilization, to support its operations.

In late June, Scotland officially opened the Glendoe Hydro Scheme, a 100-MW project whose construction near Loch Ness in the Scottish Highlands was the region’s biggest civil engineering project in recent times. Planning for the project began in 2001, and it took three years to build. Today, the project has the highest head — the […]

Biomass — plant matter that’s grown to generate energy — converted into electricity could result in 81% more transportation miles and 108% more emissions offsets than ethanol, according to U.S. researchers. In addition, the electricity option would be twice as effective at reducing greenhouse gas (GHG) emissions. The study, published in the May 22 issue […]

Uncertainty about CO₂ emissions legislation is prompting power plant owners to consider the possibility of accommodating "add-on" CO₂ capture and sequestration solutions for coal-fired plants in the future. Those same plant owners may be overlooking the possibility that future natural gas – fired combined cycles will also be subject to CO₂ capture requirements. This month we examine the capture options. In a future issue, Part II will present the installation and operating costs of different carbon capture technologies.

On August 5, President Barack Obama announced that 48 new advanced battery and electric drive projects will receive $2.4 billion in funding from the Department of Energy under the American Recovery and Reinvestment Act. The announcement marks the single largest investment in advanced battery technology for hybrid and electric-drive vehicles ever made. DOE funds will […]

Over the past decade, the development of new natural gas – fired generating assets has been similar to an amusement park roller coaster ride — very high peaks and the lowest of lows, with fast and stomach-churning movement between. Expect the ride to continue into the near future.

Improper pressure-sensing line design or installation is often found to be the cause of poor sensing system accuracy and response time. Here’s how to identify and solve those pesky pressure sensor problems in short order.

One key area at the 800-MW Michoud power station where O&M excellence is evident is in maintaining plant water quality.

Is it possible to develop a business model whereby an economic dip can be used to a market advantage? One client uses a sports analogy to describe this opportunity: "We are between seasons, and we have an opportunity to recruit and retool our team for the future." This just might be the right time to retool your human resources processes to avoid past hiring mistakes and adopt new hiring practices that will maximize the life-cycle value of your company’s human capital.

If what we have seen this spring and summer is global warming, my farm says “bring it on.” That sense that there is no climate crisis may present the Obama administration with a difficult choice between energy or health care legislation this fall in Congress. Energy legislation likely will fail.

Emerson’s new 475 Field Communicator extends beyond device configuration functionality to provide advanced device diagnostic and troubleshooting capabilities in the field and on the bench so users can work more efficiently. Quick boot-up and fast operating time mean that jobs can be performed quickly and easily, while longer battery life ensures days — not hours […]

Carbon is poised to become an auditable and verifiable reporting requirement for American business. Because utilities are among the organizations with the most at stake in a carbon-constrained economy, they should proactively tackle carbon management and carbon accounting in spite of uncertainties about the precise formulation of the final regulatory framework. In short, whether a carbon accounting requirement is legislative, administrative, or driven by business partners and consumers, now is the time for utilities to act.

The stage is being set for negotiating a successor agreement to the Kyoto Protocol. The U.S. is trying to exert some leadership in the international climate change debate by attempting to build consensus for binding carbon emission reductions prior to the upcoming Copenhagen meeting. Meanwhile, carbon legislation is, thankfully, stalled in the Senate, and developing countries are rejecting our entreaties. You can’t win if other countries don’t want to play.

The consumer, societal, and business benefits of grid moderniaztion are unclear, because the vast majority of grid-related stimulus funding appears destined to primarily expand, not cure, the ailing system we have today.

By Kennedy Maize Bobby Hefner, the doyen of deep gas, is back on the energy policy scene in a big way. That’s the only way Hefner has ever wanted to be seen: on a big canvas. Back in the 1980s, Hefner’s Oklahoma-based GHK company was the prophet of natural gas finds way down below where […]

The board of South Carolina’s largest power producer, Santee Cooper, on Monday voted to suspend construction of the proposed $2.2 billion Pee Dee Energy Campus—a 600-MW coal-fired power plant— in Florence County, S.C.. The state-owned utility cited the recession, lowered power demand, and proposed federal government regulations as primary reasons for its decision.

The Tennessee Valley Authority—the largest public utility in the U.S.—is reportedly considering shuttering two of its oldest coal-fired power plants. At the same time, it is moving forward with plans to end wet storage of ash and gypsum at fossil fuel plants, with a goal of modernizing its facilities and impoundments.

Fatalities at the 6,400-MW Sayano Shushenskaya plant in southern Siberia rose to 71 on Tuesday after several bodies were recovered as water was drained from the turbine room that completely flooded following an explosion on Aug. 17 at the giant hydropower station in the Russian Federation. Four workers remain missing.

American Electric Power (AEP) last week said it would request federal funding from the Department of Energy’s Clean Coal Power Initiative Round 3 to pay part of the costs of installing the nation’s first commercial-scale carbon dioxide capture and storage system on its Mountaineer coal-fired power plant in New Haven, W.Va.
