Blowing in the right direction

A week after the suggestion by the Massachusetts Institute of Technology that offshore turbines could store their excess energy through an underwater pumped hydro mechanism comes the news that a wind institute will be considering what it describes as “next-generation energy storage.” While no further details have been given, the storage project will be part of programme of research at Texas Tech University’s newly created the National Wind Institute (NWI).

Aiming to better support interdisciplinary research and educational opportunities in wind science, engineering and energy, and announced on May 6 at the American Wind Energy Association WINDPOWER 2013 Conference and Exhibition in Chicago, the NWI is an amalgamation of the former Wind Science and Engineering research centre and the Texas Wind Energy Institute.

Another sign that wind is waking up to the need for energy storage is the first reported purchase of GE’s 2.5-120W wind turbines. As well as an impressive suite of predictive and management technologies, the new model (named “Brilliant” by the company) is the first to have on-board battery energy storage, in the shape of GE’s Durathon units. Invenergy has ordered three machines as part of an 86-turbine deal with GE for its Mills County, Texas, wind farm.
