Research Highlights

New World Record Achieved in Solar Cell Technology

A concentrator solar cell based on an invention by NREL researchers and produced by Boeing-Spectrolab recently achieved a world-record conversion efficiency of 40.7 percent, establishing a new milestone in sunlight-to-electricity performance. The results were confirmed by the National Center for Photovoltaics at NREL.

The 40.7 percent cell was developed using a unique structure to make a multi-junction solar cell. This type of cell achieves a higher efficiency by capturing more of the solar spectrum. In a multi-junction cell, individual cells are made of layers. Each layer captures part of the sunlight passing through the cell allowing the cell to get more energy from the sun's light. NREL's Jerry Olson and Sarah Kurtz invented and developed this solar cell in the mid-to-late 1980s and licensed the technology to Spectrolab in 1996. The record-setting cell was developed, in part, under an NREL High Performance Photovoltaic subcontract. Read More

NREL Dedicates New Wind to Hydrogen Project

The Wind to Hydrogen Project will look at the production of hydrogen from wind energy and converting that wind power to a stored fuel for later use.

NREL and Xcel Energy recently dedicated a new demonstration project at the National Wind Technology Center near Boulder, Colo., that will examine system integration issues with the production hydrogen from wind energy and the compression, storage and use of the hydrogen.

Currently, there are limitations to both wind power and hydrogen. Wind farms only generate electricity when the wind is blowing. Hydrogen, while the most common element in the universe, isn't found in its pure form on Earth and must be either electrolyzed from water or stripped out of natural gas. By combining the two technologies, researchers can convert intermittent wind power to a stored fuel for use at anytime.

Two NREL wind turbines will be connected to devices called electrolyzers, which pass the wind-generated electricity through water to split the liquid into hydrogen and oxygen. The hydrogen can be stored and used later to generate electricity from either an internal combustion engine turning a generator or from a fuel cell. A trailer will house the electrolyzers and a device to compress the hydrogen for storage; four large, high-tech tanks to store the hydrogen; a generator run by an engine that burns hydrogen; and a control room building, where computers monitor all the steps of the process. NREL and Xcel are each paying part of the $2 million budget for the two-year project. Read More

Working with NREL

NREL's Innovation for a Safer Hydrogen Economy

Working with hydrogen is becoming a larger part of a clean energy future. That work will be safer, thanks to technology developed by NREL and commercialized by Nuclear Filter Technology (NucFil).

Many industries rely on the ability to quickly, easily and reliably sense the presence of hydrogen because of its naturally explosive and dangerous nature. NREL's fiber optic hydrogen sensor is an innovative technology that uses a thin glass or plastic fiber optic strand to transmit light to a thin-film material that changes color in the presence of hydrogen.

A Cooperative Research and Development Agreement between the two organizations allows NucFil to work with scientists and engineers at NREL to further develop these new hydrogen sensors.

This agreement is an example of how a technology development at NREL can be moved into the marketplace. NREL's Technology Transfer team routinely works with private and public sector agencies to move NREL-developed technologies and expertise into commercially viable products and businesses. The Laboratory offers research and technology development opportunities with industry partners, utilities, state agencies, universities, and other economic development organizations to foster the transfer and application of NREL's research expertise and technology. NREL does not, however, provide funding assistance to potential research partners under these types of partnerships.

Agreements

A Cooperative Research and Development Agreement is for companies looking to conduct joint research with NREL. A Work-for-Others agreement is appropriate when a company wants the Laboratory to conduct all the research work with no collaboration from their organization.

Facilities, Technology Licenses

NREL researchers and facilities are available for use by industry and research organizations and technologies are available for licensing for the development of commercial products using NREL discoveries that have been protected by patents, copyrights, and trademarks.

NREL's Economic Development program helps clean energy entrepreneurs develop business connections, and provides access to networks supporting the success of early-stage clean energy companies.

Clean Energy Alliance to Expand NREL's Business Assistance Model

The National Alliance of Clean Energy Business Incubators (NACEBI) begun in 2000 by NREL has become the Clean Energy Alliance, a not-for-profit organization dedicated to the development of clean energy businesses. The Clean Energy Alliance will take the successful model of the NACEBI and expand on it by offering greater resources and a broader geographic reach.

The Clean Energy Alliance, which will maintain close ties with NREL and the U.S. Department of Energy, plans to add 10 more incubators in 2007. It will offer expertise, business connections and information essential to accelerating the growth of clean energy businesses nationwide. The Alliance will host a variety of workshops and forums and develop assistance for refining company business plans. Other activities of the Clean Energy Alliance will include education and outreach, developing and recognizing markets, and helping define research and development strategies. Read More

Plextronics Receives Clean Energy Entrepreneur of the Year Award

Plextronics, Inc., a world leader in developing active layer technology for printed electronic devices, received the Clean Energy Entrepreneur of the Year Award at NREL's 19th Industry Growth Forum in October. The Entrepreneur of the Year competition was developed to promote and support the creation of world-class businesses delivering clean energy technology options into the energy market. The 20th Industry Growth Forum will be held in Denver, Colo., in November 2007.

Regional Mayors Pledge to Expand Efficiency and Conservation Efforts

The Denver Metro Mayors Caucus recently set an example for all local governments by signing a historic pact to expand upon current efforts promoting energy efficiency and conservation. The Metro Mayors Caucus is a voluntary regional organization comprised of mayors from throughout Colorado's Front Range.

Carol Tombari, manager of Stakeholder Relations with NREL's Public Relations Office, assisted in drafting the MOU that sets forth a commitment by mayors on behalf of their municipalities to take voluntary actions to: improve energy efficiency within their own operations; promote energy efficiency and conservation for residences and businesses; and increase awareness of programs that enable consumers and businesses to identify and implement cost-effective efficiency upgrades.

The Metro Mayors Caucus' efforts have been endorsed by organizations from across Colorado including NREL, Xcel Energy, the U.S. Green Building Council's Colorado Chapter, the Wirth Chair at the University of Colorado's Graduate School of Public Affairs and the Metro Denver Economic Development Commission.

New Lab Offers Chance to Understand an Entire Biological System

Using robotics, researchers in NREL's Systems Biology Lab can simultaneously perform hundreds of experiments a day, saving both time and money.

Converting cellulosic biomass feedstocks such as corn stover, wheat straw or switchgrass into ethanol involves two fundamental steps: breaking the long chains of cellulose and hemicellulose molecules into glucose, xylose and other sugars, and fermenting those sugars into ethanol. Microorganisms are involved in both of these steps.

The breakdown of cellulose is performed by specialized enzymes (i.e., cellulases), typically produced by fungi, to "free" the sugars present in the cellulosic biomass while other organisms such as yeasts and bacteria are used to convert these sugars into ethanol. (For more information about converting biomass to ethanol and to watch a video, visit Learning About Renewable Energy - Biofuels.)

The National Bioenergy Center's new Systems Biology Lab contains specialized instruments that allow researchers to better understand how these microscopic biological systems function. The lab has been equipped with state-of-the-art capabilities in the areas of genomics (gene structure/function and gene expression profile analysis), proteomics (cataloging and analysis of cellular proteins) and metabolomics (profiling of small molecule metabolites). These capabilities allow researchers to identify and ultimately overcome bottlenecks in the performance of microbes involved in the biomass conversion process - thereby effectively reducing the overall cost of cellulosic ethanol production.

The Systems Biology Lab is equipped with state-of-the-art capabilities that allow researchers to analyze the performance of microbes involved in the biomass conversion process.

Through the use of high-throughput screening and modern robotics capabilities, researchers can simultaneously perform hundreds if not thousands of experiments in a single day. This becomes particularly important in protein engineering, enzyme improvement and activity screening studies.

One recent addition to the new lab, a single-crystal X-ray diffraction instrument, will allow researchers to determine the three-dimensional structures of cellulases, giving them a better understanding of how these important enzymes work.
