Using high-brilliance x-rays, Stanford Univ. researchers track the process that fuel cells use to produce electricity, knowledge that will help make large-scale alternative energy power systems more practical and reliable. Fuel cells use oxygen and hydrogen as fuel to create electricity; if the process were run in reverse, the fuel cells could be used to store electricity, as well.
A new type of catalyst, based on carbon, can facilitate two opposite reactions: electrolysis of water and combustion of hydrogen with oxygen. This bi-functionality, developed by researchers in Germany, is made possible from its construction: manganese-oxide or cobalt-oxide nanoparticles which are embedded in specially modified carbon, then integrated with nitrogen atoms in specific positions.
Researchers at Pacific Northwest National Laboratory have developed a porous material to replace the graphite traditionally used in a battery's electrodes. Made from silicon, which has more than 10 times the energy storage capacity of graphite, the sponge-like material can help lithium-ion batteries store more energy and run longer on a single charge.
Researchers at Princeton Univ. joined with experts at Liquid Light Inc. to devise an efficient method for harnessing sunlight to convert carbon dioxide into a potential alternative fuel known as formic acid. This type of acid is already being explored as an alternative in fuel cells. The new process takes place inside an electrochemical cell, which consists of metal plates the size of lunch-boxes that enclose liquid-carrying channels.
Despite five months of below-average temperatures and twice the normal amount of snowfall, NIST's Net-Zero Energy Residential Test Facility (NZERTF) in Washington, D.C. ended its one-year test run with 491 KW-h of extra energy. Instead of paying almost $4,400 for electricity, the experimental all-electric house actually earned a credit by exporting surplus energy to the local utility.
Experts don't fully understand how “plastic” solar panels work, which complicates the improvement of their cost efficiency and hinders wider use of the technology. However, an international team has now determined how light beams excite the chemicals in solar panels, enabling them to produce charge. Their findings were made possible with the use of femtosecond Raman spectroscopy.
Researchers in Germany have produced a new material the size of a sugar cube that has a surface area equivalent to more than seven tennis courts. This novel type of nanofiber has a highly ordered and porous structure gives it an extraordinarily high surface-to-volume ratio and could be a key enabling technology for lithium-sulfur batteries.
SiEnergy Systems, an Allied Minds company commercializing low temperature thin film solid oxide fuel cell (SOFC) technology from Harvard University, has announced that it has been selected for $2.65 million in funding from Advanced Research Projects Agency-Energy (ARPA-E). SiEnergy has develop innovative and unique hybrid electrochemical system that performs as both fuel cell and battery.
Rice Univ. chemical engineer Michael Wong has spent a decade amassing evidence that palladium-gold nanoparticles are excellent catalysts for cleaning polluted water, but even he was surprised at how well the particles converted biodiesel waste into valuable chemicals.
Fossil fuel emissions release billions of tons of carbon into the atmosphere each year. In Brazil, the demand for alternative energy sources has led to an increase in biofuel crops. New research demonstrates the high carbon costs of converting intact Brazilian savanna compared to the carbon gains obtained from converting underutilized pastureland for biofuel crops.
Confined water exists widely and plays important roles in natural environments, particularly inside biological nanochannels. After several years of work, scientists in China have developed a series of biomimetic nanochannels that can serve as the base for confined transportation of water. The technology suggests a potential use in energy conversion systems.
Researchers at the Joint BioEnergy Institute (JBEI) have unveiled the first glycosyltransferase clone collection specifically targeted for the study of the biosynthesis of plant cell walls. The idea behind “the JBEI GT Collection” is to provide a functional genomic resource for researchers seeking to extract the sugars in plant biomass and synthesize them into clean, green and renewable transportation fuels.
Concentrating solar power (CSP) could supply a large fraction of the power supply in a decarbonized energy system, according to a new study of the technology and its potential practical application. For this research, scientists simulated the construction and operation of CSP systems in four regions around the world, taking into account weather variations, plant locations, electricity demand, and costs.
A research center at Purdue Univ.'s Discovery Park has been awarded a $12 million, four-year grant as part of a $100 million U.S. Dept. of Energy initiative to accelerate scientific breakthroughs needed to build the 21st century energy economy. The Purdue-led C3Bio will use the additional funding to advance methods for converting plant lignocellulosic biomass to biofuels and other bio-based products.
Rice Univ. scientists have created a one-step process for producing highly efficient materials that let the maximum amount of sunlight reach a solar cell. The Rice laboratory of chemist Andrew Barron found a simple way to etch nanoscale spikes into silicon that allows more than 99% of sunlight to reach the cells’ active elements, where it can be turned into electricity.
Los Alamos National Laboratory researchers have demonstrated an almost four-fold boost of the carrier multiplication yield with nanoengineered quantum dots. Carrier multiplication is when a single photon can excite multiple electrons. Quantum dots are novel nanostructures that can become the basis of the next generation of solar cells, capable of squeezing additional electricity out of the extra energy of blue and ultraviolet photons.
Researchers the world over are investigating solar cells which imitate plant photosynthesis, with the goal of using sunlight and water to create synthetic fuels such as hydrogen. Scientists in Switzerland have developed this type of photoelectrochemical cell, but this one recreates a moth’s eye to drastically increase its light collecting efficiency. The cell is made of cheap raw materials: iron and tungsten oxide.
Washington State Univ. researchers have developed the first fuel cell that can directly convert fuels, such as jet fuel or gasoline, to electricity, providing a dramatically more energy-efficient way to create electric power for planes or cars. About 10 years ago, the researchers began developing a solid-oxide fuel cell to provide electrical power on commercial airplanes.
Tesla CEO Elon Musk promised Thursday to give away the company's entire patent portfolio to all comers, as long as they promised not to engage courtroom battles over intellectual property. The decision is meant to encourage other automakers to expand beyond gasoline-burning automobiles, and opens the door to more collaboration with Tesla, which is already making electric systems for Daimler and Toyota.
The possible bid by Mitsubishi Heavy Industries for turbine businesses of French engineering firm Alstom is part of Japan's effort to carve out a share of the lucrative global energy infrastructure business. Mitsubishi and German rival Siemens AG said Wednesday they are considering a joint bid for parts of Alstom and will decide by Monday whether to pitch it to Alstom's board.
Turning the “hydrogen economy” concept into a reality, even on a small scale, has been a bumpy road, but scientists are developing a novel way to store hydrogen to smooth out the long-awaited transition away from fossil fuels. Their report on a new solid, stable material that can pack in a large amount of hydrogen that can be used as a fuel appears in Chemistry of Materials.
Researchers at the University of California, Riverside Bourns College of Engineering have developed a 3-D, silicon-decorated, cone-shaped carbon-nanotube cluster architecture for lithium ion battery anodes that could enable charging of portable electronics in 10 minutes. It also increases cell capacity and reduces size and weight by 40%.
Since the early 1970s, lithium has been the most popular element for batteries because of it’s low weight and good electrochemical potential. But it is also highly flammable. Researchers have recently married two traditional theories in materials science that can explain how the charge dictates the structure of the material. And using this they may be able to move to other materials, such as block copolymers, for use in batteries.
