NREL Creates New Pathways for Producing Biofuels and Acids from Cyanobacteria (Fact Sheet)
Cyanobacteria use photosynthesis to convert carbon dioxide into glycogen, a carbohydrate that is stored in the cells as an energy source. However, researchers at the National Renewable Energy Laboratory (NREL) have discovered that this photosynthesis can be redirected to produce lipids and valuable organic acids. The research could yield a new source of biofuels, because the lipids canpotentially be extracted from the bacteria and converted into biodiesel.

NREL Spurred the Success of Multijunction Solar Cells (Fact Sheet)
Many scientists once believed that high-quality gallium indium phosphide (GaInP) alloys could not be grown for use as semiconductors because the alloys would separate. However, researchers at the National Renewable Energy Laboratory (NREL) thought differently, and they employed GaInP in a material combination that allowed the multijunction cell to flourish. The multijunction cell is now the workhorse that powers satellites and the catalyst for renewed interest in concentrator photovoltaic products.

NREL Produces Ethylene via Photosynthesis; Breakthrough Offers Cleaner Alternative for Transportation Fuels [Fact Sheet]
NREL scientists have demonstrated a way to produce ethylene through photosynthesis, a breakthrough that could lead to more environmentally friendly ways to produce a variety of materials, chemicals, and transportation fuels. The scientists introduced a gene into a cyanobacterium and demonstrated that the organism remains stable through at least four generations, producing ethylene gas that can be easily captured. In the laboratory, the organism, Synechocystis sp. PCC 6803, produced 720 milligrams of ethylene per liter each day.

NREL Collaborative Improves the Reliability of Wind Turbine Gearboxes [Fact Sheet]
Gearbox failures have a significant impact on the cost of wind farm operations. To help minimize gearbox failures, in 2007 the National Renewable Energy Laboratory (NREL) initiated the Gearbox Reliability Collaborative (GRC), which consists of manufacturers, owners, researchers, and consultants. Based on all the lessons learned from the past five years, the GRC has now produced a new and improved design, which is projected to yield an operating lifetime of 12 years, more than triple that of the previous redesigned gearbox. The GRC findings will result in increased gearbox reliability and an overall reduction in the cost of wind energy.

NREL Develops OpenEI.org, a Public Website Where Energy Data can be Generated, Shared, and Compared (Fact Sheet)
The National Renewable Energy Laboratory (NREL) has developed OpenEI.org, a public, open, data-sharing platform where consumers, analysts, industry experts, and energy decision makers can go to boost their energy IQs, search for energy data, share data, and get access to energy applications. The free site blends elements of social media, linked open-data practices, and MediaWiki-based technology to build a collaborative environment for creating and sharing energy data with the world. The result is a powerful platform that is helping government and industry leaders around the world define policy options, make informed investment decisions, and create new businesses.

NREL Investigates Critical Properties of Perovskite Halides Solar Cells (Fact Sheet)
Organometallic halide perovskites (e.g., CH 3 NH 3 PbI 3 ) are a novel class of light-absorbing materials that have demonstrated exceptional progress in solar cell performance. But despite rapid progress in device performance, understanding the structural and electronic properties of halide perovskites is just in its infancy—and obtaining information on charge diffusion length is critical for the development of perovskite solar cells with balanced light harvesting and charge collection. To address this need, researchers at the National Renewable Energy Laboratory (NREL) have reported on the effect of TiO 2 film thickness on charge transport and recombination in solid-state mesostructured perovskite CH 3 NH 3 PbI 3 solar cells using spiro-MeOTAD as the hole conductor

NREL 2012 Achievement of Ethanol Cost Targets: Biochemical Ethanol Fermentation via Dilute-Acid Pretreatment and Enzymatic Hydrolysis of Corn Stover
For the DOE Bioenergy Technologies Office, the annual State of Technology (SOT) assessment is an essential activity for quantifying the benefits of biochemical platform research. This assessment has historically allowed the impact of research progress achieved through targeted Bioenergy Technologies Office funding to be quantified in terms of economic improvements within the context of a fully integrated cellulosic ethanol production process. As such, progress toward the ultimate 2012 goal of demonstrating cost-competitive cellulosic ethanol technology can be tracked. With an assumed feedstock cost for corn stover of $\$$58.50/ton this target has historically been set at $\$$1.41/gal ethanol for conversion costs only (exclusive of feedstock) and $\$$2.15/gal total production cost (inclusive of feedstock) or minimum ethanol selling price (MESP). This year, fully integrated cellulosic ethanol production data generated by National Renewable Energy Laboratory (NREL) researchers in their Integrated Biorefinery Research Facility (IBRF) successfully demonstrated performance commensurate with both the FY 2012 SOT MESP target of $\$$2.15/gal (2007$\$$, $\$$58.50/ton feedstock cost) and the conversion target of $\$$1.41/gal through core research and process improvements in pretreatment, enzymatic hydrolysis, and fermentation.
