NREL and Statoil collaborate to make first multi-turbine floating offshore wind array

A recent study performed by the National Wind Technology Center (NWTC) at the National Renewable Energy Laboratory (NREL) is helping Norway-based Statoil prepare for the installation of what has the potential to be the world’s first multi-turbine floating offshore array. Statoil deployed the first spar-based system called Hywind Demo in 2009, which is still operating

New wind resource maps reach higher heights

The National Renewable Energy Laboratory (NREL) and AWS Truepower recently released maps that illustrate the potential for wind-energy development using more advanced wind turbine technologies. Wind resource maps are one tool wind industry professionals use in the early stages of wind project planning to understand the potential for wind development in a region. Because stronger


Battery second use offsets electric vehicle expenses, improves grid stability

Editor’s Note: The article posted here was originally posted on NREL’s Newsroom by Anya Breitenbach. Breitenbach examines battery second use (B2U) strategies that may be able to offset expenses for plug-in electric vehicles (PEVs). For more information on B2U strategies, click this link. Plug-in electric vehicles (PEVs) have the potential to dramatically drive down consumption of


NREL partnerships to help the grid accommodate more renewable energy

The Energy Department’s National Renewable Energy Laboratory (NREL) announces five new partnerships that will award up to $6.5 million in federal funds to technical teams throughout the country. The cost-shared projects with industry, universities, and other stakeholders will address the challenge of enabling the nation’s electric grid to handle increasing amounts of renewable energy. NREL is


U.S. strides forward with lidar-controlled turbine

An industry landmark moment occurred on Oct. 29, 2014, when a team that included NREL, Stuttgart University and DNV GL achieved control of an operational wind turbine using a ZephIR wind lidar. “This new installation of a ZephIR DM has taken a new direction in reducing yaw misalignment by providing the opportunity for full turbine


NREL and Clemson University collaborate on wind energy testing facilities

Through a Cooperative Research and Development Agreement (CRADA), the Energy Department’s National Renewable Energy Laboratory (NREL) and Clemson University will partner to share resources and capabilities in the operation and development of testing facilities. The CRADA also includes the exchange of staff for training and research and development purposes, including collaborative participation in facility commissioning


NREL’s economic impact tops $872 million

The economic impact of the Energy Department’s National Renewable Energy Laboratory (NREL) was $872.3 million nationwide in fiscal year 2014, according to a study by the University of Colorado Boulder’s Leeds School of Business. The study estimates NREL’s impact to Colorado’s economy totaled $701 million, a decline of 1.6 percent from the prior year. The


Nation’s first power-to-gas project explores solution for storing excess renewable energy

Southern California Gas Company (SoCalGas) has joined with the Energy Department’s National Renewable Energy Laboratory (NREL) and the National Fuel Cell Research Center (NFCRC) to launch demonstration projects to create and test a carbon-free, power-to-gas system for the first time ever in the United States. The technology converts electricity into gaseous energy and could provide North

Learning how to prevent bird-turbine collisions

A trained falcon named Houdini darts and soars next to a wind power plant in the shadow of the Colorado Rockies, gathering radar data that could someday save the lives of his avian brethren. Peregrine gyrfalcon Houdini is the VIP guest of the Energy Department’s National Renewable Energy Laboratory (NREL), and he performs his strategic


NREL and partners review key issues and lessons learned from U.S. wind integration studies

As a complement to the Department of Energy’s (DOE) recently released Wind Vision report, a new paper summarizes the lessons learned from actual power systems operational practice, along with some of the most relevant and comprehensive wind integration studies conducted during the past several years. In the years since the DOE’s “20% Wind Energy by
