In his keynote speech this May to the Global Roundtable on Climate Change, held in Iceland and hosted by the Earth Institute of Columbia University, Ólafur Ragnar Grimsson—the president of Iceland—challenged government and business leaders to take measurable steps now to build a prosperous and sustainable future through smart science and public policy. Grimsson’s call […]
The length of term allowed for power sales contracts is a critical determinant of the ability of states to meet their increasingly ambitious renewable power targets. Many utilities advocate limiting terms to 10 or perhaps 15 years for renewable energy contracts, emphasizing the "flexibility" that shorter terms offer. In contrast, contract terms of 20 or […]
Promoting renewable exports The DOE is not the only U.S. government department promoting renewable energy. Any U.S. energy firm or supplier looking to export its goods and services can tap the services of the Energy Team at the Commerce Department’s International Trade Administration (ITA), which is part of the U.S Commercial Service (USCS). The […]
Renewable power development will continue to grow in the U.S., with the nonhydro total reaching 53,121 MW by the end of 2016. So predicts a soon-to-be-released report from Boulder, Colo.–based Platts Analytics (which, like POWER, is a part of Platts, a division of The McGraw-Hill Companies). If all that capacity goes on-line, it would […]
For thousands of U.S. businesses, a lesson learned the hard way over the past few years is the need for an absolutely reliable electricity source. Challenging the standard backup power options, proton exchange membrane fuel cells are making a play for this duty.
One of the key projects at the U.S. Navy’s Office of Naval Research is developing an integrated ship power system capable of supplying power both to propulsion systems and to advanced electric weapons, launchers, and high-power sensors. It would be the ultimate naval power T&D system. The "all-electric warship," which some predict will have as much of an impact on navies as the nuclear submarine, is still a decade or two away. But the first generation of electric systems is already being installed on U.S. warships currently under construction.
Balmy days are on the horizon for geothermal energy. The renewal of the Production Tax Credit in the U.S. and improved drilling and electricity production techniques are the two main reasons geothermal energy advocates are bullish about the industry. POWER looks at some interesting installations and explains why the optimism is well-founded.
Several advanced battery technologies tailored for utility applications have doffed their white coats and donned hard hats. These new bulk energy storage devices, which can almost instantly shave peaks and shift loads, are the answer to the dreams of T&D system designers and operators. Finally, years of R&D in electrochemistry are beginning to pay dividends in the field.
Most people think of fuel cells within a single, "not ready for prime time" context: powering tomorrow's automobiles. But stationary fuel cell power plants are beginning to power some industrial facilities today. The need for heat as well as ultraclean power, and the availability of a renewable fuel, recently came together in a Seattle suburb, site of the world's first commercial megawatt-scale fuel cell power plant—powered entirely by gas produced by anaerobic digestion of municipal wastewater.
