Hungary Building High-Efficiency Gas-Fired Plant

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 […]

Recession Reduces Demand for Electricity

When roving Contributing Editor Mark Axford attended several recent energy conferences, he found the same questions asked at each one about new U.S. generation sources and consumption patterns. Unfortunately, the experts had few good answers to those questions.

CHP: Helping to Promote Sustainable Energy

Because combined heat and power (CHP) plants optimize energy use, they cut fuel costs and pollution. Even though U.S. power plants have been using CHP for decades, today’s energy experts have a newfound appreciation for its ability to promote sustainable energy use.

Turkey Opens Electricity Markets as Demand Grows

Turkey’s growing power market has attracted investors and project developers for over a decade, yet their plans have been dashed by unexpected political or financial crises or, worse, obstructed by a lengthy bureaucratic approval process. Now, with a more transparent retail electricity market, government regulators and investors are bullish on Turkey. Is Turkey ready to turn the power on?

Canada Moves to Rebalance Its Energy Portfolio

Though Canada is rich in fossil fuels, nuclear power may fuel a significant portion of the nation’s future electrical generation needs, especially in provinces that have traditionally relied on hydropower and fossil fuels.

Advanced Modeling Tools Slash Combustor Analysis Chores

Combustor design simulation requires the resolution of complex geometry, turbulent flow patterns, heat transfer, and detailed chemistry. Although computational fluid dynamics (CFD) can simulate the reacting flow in realistic geometries, it requires the use of severely restricted chemistry models that are too simple to accurately simulate emissions and operational stability. A new simulation tool is now available that eliminates this CFD shortcoming while significantly reducing computing time.

Gas Hydrates: Fuel of the Future?

Gas hydrates, a form of natural gas that forms when methane from the decomposition of organic material comes into contact with water at low temperatures and high pressures, could play a role — even if a small one — in future fuel supplies, researchers attending a March meeting organized by the American Chemical Society suggested.

Powering the People: India’s Capacity Expansion Plans

India has become a global business power even though hundreds of millions of its citizens still live in poverty. To sustain economic growth and lift its people out of poverty, India needs more — and more reliable — power. Details of government plans for achieving those goals demonstrate that pragmatism may be in shorter supply than ambition and political will.
