Expect 1,500 MW from Offshore Wind Energy in Germany
Hamburg, Germany [RenewableEnergyAccess.com]
According to the CEO at REpower Systems AG, Professor Fritz Vahrenholt, it is realistic to expect offshore wind farms with an output of 1,500 megawatts (MW) in Germany by the end of 2011.
Vahrenholt also announced a short-term decision on Bremerhaven as the site for the serial production of the offshore turbine REpower 5M, to start as early as 2007.
During the National Maritime Conference in Hamburg, Vahrenholt welcomed Germany's resolution to adjust the infrastructure law so that grid-connection costs are borne by the grid operators.
Vahrenholt also announced a short-term decision on Bremerhaven as the site for the serial production of the offshore turbine REpower 5M, to start as early as 2007.
The dimensions of the 5M, whose nacelle has the measurements of a single family home and weighs approximately 290 tons, place particular demands on the size and infrastructure of the production site.
The first 5M was thus manufactured at HDW shipyard in Kiel and four subsequent 5Ms were produced at the J. Kramer shipyard in Bremerhaven. All other REpower Systems AG wind turbines are manufactured in Husum and Trampe/Brandenburg.

Wind-powered System Under Way to Purify Water
Wind-powered System Under Way to Purify Water
Niskayuna, New York [RenewableEnergyAccess.com]
GE Global Research is partnering with Texas Tech University (TTU) to develop affordable water desalination systems to increase the quantity and quality of clean water in arid areas around the world.
"Developing cost effective technologies that address improving water quality and availability are of critical importance to many water stressed areas in this region."
-- Dr. Dean Smith, Texas Tech University, VP for Research
The GE-Texas Tech partnership will focus on the integration of renewable energy systems, such as wind turbines, with membrane desalination processes. The development of the integrated renewable energy-water system can reduce the cost of creating new sources of freshwater from impaired resources, such as brackish water, by directly addressing the major component of operating cost of desalination systems - energy.
"Up to fifty percent of the operating costs of desalination is derived from energy consumption," said Dr. Minesh Shah, project leader, GE Global Research. "With the potential for large variability in energy costs due to fuel price volatility, desalination systems can have significant operational costs. The integration of wind energy provides an opportunity to mitigate this variability and allow for a lower cost desalination system."
"Developing cost effective technologies that address improving water quality and availability are of critical importance to many water stressed areas in this region," said Dr. Dean Smith, Vice President for Research at TTU. "We are pleased to partner with the GE Global Research Center to work together on this problem of both regional and world-wide importance."
The focus of the research partnership will be the integrated control and optimization of the two systems to improve operations, reduce capital cost and reduce energy consumption. This would help to improve the commercialization of a renewable energy-water system. The program aims to develop a commercial scale demonstration within the next several years.
The partnership is part of GE's company-wide ecomagination initiative, in which GE has pledged to more than double its level of investment in the development of cleaner energy technologies, from $700 million to $1.5 billion, over the next five years.
