Siemens Finalizes HelWin1 HVDC Offshore Platform Install
Siemens says that it has completed a key development in linking two offshore wind farms to the German mainland. Using Siemens HVDC technology, the HelWin1 offshore platform will transform alternating current generated by the Nordsee Ost and Meerwind wind farms and convert them into direct current for transmission onto a land-based station located northwest of Hamburg where electricity will be converted back into AC for the grid. The platform is installed 22 meters above sea level to protect it from heavy waves and has been designed for decades of operation in the North Sea. The link is due to be energized in 2014.
Japanese Nuclear Regulator Sees Ocean Dump for Fukushima Water
Nuclear Regulation Authority Chairman Shunichi Tanaka said recently that Tokyo Electric Power Co. plans to manage radioactive water at its Fukushima plant by a controlled ocean discharge once toxicity is brought within legal limits. Tanaka emphasized the importance of understanding the need to make difficult decisions today in order to avoid bigger problems in the future. He says that the ocean dump could be necessary as the government prepares to present its plan for handling tainted water that has been increasing by 400 tons a day. Japan’s Nuclear Emergency Response Headquarters may present its response to the crisis this week.
Rupee’s Plunge Threatens India’s Promising Wind Industry
The rupee’s 17 percent slide against the dollar, its biggest plunge in 20 years, is endangering the recovery of India’s $1.6 billion wind power industry as higher finance and import costs negate benefits from a government subsidy restored last month. India’s wind industry was slated to beat the U.S. for the first time this year after the government reintroduced a cash incentive in August, but the currency’s plunge has affected investor confidence and has largely contributed to a 42 percent drop in installations in the 12 months through March.
Solar Powered Catamaran Arrives in Europe
PlanetSolar, a solar-powered sea vessel, completed a 4598 kilometer journey by crossing the Atlantic Ocean from Canada to Belgium. Leaving Canada on 6 August and traveling at an average speed of 4.5 knots, the ship arrived in Europe 23 days later. Built in Germany, PlanetSolar is the world’s largest solar ship and is powered exclusively by solar energy. During the voyage, researchers from the University of Geneva took physical and biological measurements along the Gulf Stream as part of an ongoing scientific project. In May 2012, the catamaran completed the first solar-powered trip around the world, sailing for 584 days.
