  • Osmotic Power Makes Headway

    Statkraft began operating its 4-kW prototype osmotic power plant at Tofte, just outside Oslo, Norway, in 2009. Now the firm reports that it is close to developing a large-scale plant. In June, Statkraft and Japanese materials manufacturer Nitto Denko/Hydranautics signed an agreement for the development and supply of membranes specifically designed for use in large-scale osmotic power plants.

  • Pushing the 60% Efficiency Gas Turbine Barrier

    Gas turbine makers GE, Siemens, and Mitsubishi Heavy Industries (MHI) in the last week of May separately profiled unprecedented results from development or testing of three innovative combined-cycle gas turbine (CCGT) technologies.

  • Germany to Shut Down All Nuclear Reactors

    Germany’s Chancellor Angela Merkel at the end of May officially endorsed a plan to shut down all 17 of the nation’s nuclear power plants by 2022. The decision, which gives the power-intensive nation just over a decade to find new sources of power for 23% of its energy needs, has had reverberations all over the world, though the future of nuclear—through growth in developing nations—continues to look sturdy.

  • TEPCO: Most Fuel at Daiichi 1 Melted

    Tokyo Electric Power Co. (TEPCO) in May discovered—after calibrating water gauges—that the water level in the reactor pressure vessel of Unit 1 at the quake- and tsunami-ravaged Fukushima Daiichi nuclear plant may have dropped to such low levels that the fuel was completely uncovered. This caused almost all the fuel pellets to melt and fall to the bottom of the vessel at a relatively early stage in the accident—roughly 15 hours after the March 11 earthquake that killed an estimated 28,000.

  • Holtec, Westinghouse Roll Out Small Modular Reactor Designs

    As the Daiichi nuclear crisis has governments around the world reconsidering their nuclear-heavy energy plans and scrutinizing the safety of existing reactors and third-generation designs, several developers are touting the merits of small modular reactors (SMRs).

  • Carbon Trust: Marine Energy Has High Potential but Faces Several Challenges

    In a an analysis released this May, nonprofit UK group Carbon Trust admits that there is “still considerable uncertainty as to whether wave and tidal systems will play a meaningful role in meeting global energy needs,” but it suggests, based on high and low scenarios, that up to 240 GW of marine capacity could be deployed globally by 2050. Roughly 75% of this capacity will come from wave and the remainder from tidal energy.

  • POWER Digest (July 2011)

    Indonesia Sees Surge in Contracts for New Power Plants. Indonesia is Southeast Asia’s largest economy, but because it is stricken by chronic power shortages that limit economic growth, the nation’s government is pushing for massive infrastructure improvements. A consortium of Japan’s Electric Power Development (J-Power), Itochu Corp., and Adaro Energy, an Indonesian coal miner, on […]

  • Germany Considers Accelerated Nuclear Exit on Fukushima Worries

    In the wake of the devastating nuclear crisis afflicting the Fukushima Daiichi nuclear plant in Japan, Germany has embarked on an abrupt shift away from nuclear power, shutting down eight reactors for safety checks and ditching concerted efforts to keep nuclear power plants open in the long term. In mid-April, Chancellor Angela Merkel told reporters that leaders of Germany’s 16 states all want to “exit nuclear energy as soon as possible and make the switch to supplying via renewable energy.” The policy reversal has incited ardent opposition from the energy sector and industry.

  • Countries Abandon Subsidies for Renewables en Masse

    Stricken by the economic crisis and forced to implement austerity measures, several countries around the world have been forced to abandon or slash subsidies for renewable power producers.

  • Battery That Extracts Energy from Water Salinity Difference

    A rechargeable battery developed by researchers from Stanford University employs the difference in salinity between freshwater and saltwater to generate a current.
