Secretary of the Interior Ken Salazar, speaking in Atlantic City on April 6, added more hot air to the discussion about offshore wind when he stated that windmills off the East Coast could generate enough electricity to replace most, if not all, of the coal-fired power plants in the U.S. I’m disappointed Salazar didn’t take a few minutes for fact-checking and back-of-the-envelope ciphering before his speech.

Australia, the world’s second-largest exporter of thermal coal and uranium, and a significant exporter of liquefied natural gas (LNG), faces inevitable electricity rationing and the threat of blackouts unless the government acts urgently to ensure large-scale investments are made in new power-generating capacity, experts from five nations said in April. The Australian Academy for Technology […]

Microbe Turns Carbon Dioxide into Methane A team of Penn State engineers say that a tiny self-perpetuating microbe can take electricity and directly convert carbon dioxide and water into methane, potentially producing a portable energy source with a carbon-neutral footprint. Methanogenic microorganisms produce methane in marshes and dumps, but scientists thought that the organisms turned […]

Denmark’s Risø DTU National Laboratory for Sustainable Energy in late April announced it had connected the world’s first polymer solar cell plant to the grid. The achievement follows years of research into the novel photovoltaic (PV) technology that has been touted as a future inexpensive, flexible, and customizable alternative to silicon crystal solar cells. The […]

Q: What do you get when you gather roughly two dozen top researchers from academia, government, and industry to speak on interdisciplinary energy-related issues for a week?
A: A lot of informative but crowded slides, high-octane brain power, fact-based analysis of where we are and we’re headed globally, informed questions, and surprisingly practical answers.

Southern California Edison’s (SCE) 2,250-MWe San Onofre Nuclear Generating Station (SONGS) recently took receipt of a new and upgraded generator rotor for one of its two Alstom steam turbine generator units (Figure 1). Following the successful installation and flawless start-up of this new rotor in the Unit 2 generator, the former Unit 2 rotor was […]

Germany’s E.ON laid the foundation stone in late March for a 433-MW combined-cycle power plant in Gönyü (Figure 6), a power-stricken region in northwestern Hungary. The power plant, expected to begin operation in 2011, will operate with a net efficiency of more than 58% — making it one of the most efficient power plants in […]

In the wake of the recent U.S. Supreme Court ruling related to cooling water intake practices at large power plants, many utilities are relieved to be off the hook as far as implementing expensive control upgrades to protect fish and other aquatic organisms.

News items of interest to power generation professionals.

By Kennedy Maize Remember the nuclear power renaissance coming any day soon now? Fugetaboudit. While the stars seemed aligned for new nuclear power in the U.S. in 2005 when Congress passed the Energy Policy Act, it’s all turned brown and runny. The promise of some $15 billion in loan guarantees for new nukes in the […]

New coal-fired power plant ash management regulations appear to be inevitable, perhaps as soon as year-end. The Tennessee Valley Authority and Edison Electric Institute are on board with new regulations, as long as the ash is regulated as a nonhazardous waste under the Resource Conservation and Recovery Act.

The UK has all but doomed new coal-fired capacity by simultaneously setting binding carbon reduction goals and by requiring carbon capture and sequestration (CCS) of carbon emissions from new  mid-size coal-fired power plants. Existing plants will also be required to retrofit their plants when CCS technology is demonstrated, now estimated to happen by 2020.

Utilities generally support a cap-and-trade approach to reducing carbon emissions—but only when the objective of any legislation is to promote cost-effective reductions. The least-cost alternative for consumers requires free distribution of all carbon allowances.

FirstEnergy has announced plans to repower two coal-fired units at the R.E. Burger plant to burn biomass. Conversion of the two units, expected to be completed by 2012, gets the utility off the hot seat with the EPA for alleged Clean Air Act violations.

Recent improvements in the performance of steam power plants have been achieved with advanced computerized controls. These new control schemes not only reduce fuel consumption and make the plant much more responsive, but they also can significantly decrease start-up commissioning time and cost.

Commonly, 20% of the cement (by weight) in a concrete mix is replaced by fly ash. Fly ash enhances the workability, durability, and ultimate strength of concrete at a lower cost than cement. However, mercury sorbents can change the ash properties to make it unsuitable as a concrete additive. New “concrete-friendly” sorbents can keep the revenues from ash sales flowing.

Measuring combustion airflow in a coal-fired power plant can be problematic when using annubar instruments that feature small holes that can easily plug with coal dust. Sierra Instruments eliminates this big maintenance headache with its more-accurate, nonplugging thermal mass flow meter design.

Demonstrating sound knowledge, having profound passion, and being consistent with your message are essential when trying to persuade someone to adopt your point of view. A recent press briefing hosted by a well-known pro-coal industry group failed on all counts.

Did a recent Supreme Court decision give a license to firms to use “best practices” concepts to gut effective environmental standards?

The U.S. Nuclear Regulatory Commission (NRC) in early April granted Entergy Nuclear an extended license for the Oyster Creek nuclear plant in New Jersey, the oldest operating nuke in the U.S. The plant will now be able to operate until 2029, unless the NRC at some point in the future grants a further license extension. Nuclear power advocate William Tucker, with tongue in cheek, advocated closing the plant and other elderly units in the Northeast, in a commentary in the National Review. Tucker’s comments are reprinted with permission.

Does customer satisfaction play a meaningful role in guiding utility operations? Many utilities think it does, as do many regulators. The market apparently doesn’t. Data suggest that the jury is out on the question, and the intuitive answer may not match the empirical evidence.

Because India has large domestic coal resources (and virtually no other fuel sources); a strong incentive to deploy cheaper, well-proven generation technology; and needs to rapidly increase the availability of electricity to its citizens, the country will likely continue to rely on coal-based power in the long run.
