Unanticipated economic benefits from the shale oil and gas boom could help offset the costs of substantially reducing the U.S.'s carbon footprint, Purdue Univ. agricultural economists say. Wally Tyner and Farzad Taheripour estimate that shale technologies annually provide an extra $302 billion to the U.S. economy relative to 2007, a yearly "dividend" that could continue for at least the next two decades, Tyner said.
While the powerful solvents known as ionic liquids show great promise for liberating fermentable sugars from lignocellulose and improving the economics of advanced biofuels, an even more promising candidate is on the horizon—bionic liquids. Researchers at the Joint BioEnergy Institute have developed “bionic liquids” from lignin and hemicellulose, two by-products of biofuel production from biorefineries.
A convergence of factors is propelling a market rollout of the hydrogen fuel cell vehicle, according to a new study. A key to hydrogen’s potential success is a new smart solution that clusters hydrogen fuel infrastructure in urban or regional networks, limiting initial costs and enabling an early market for the technology before committing to a full national deployment.
This could be a classic win-win solution: A system proposed by researchers at Massachusetts Institute of Technology recycles materials from discarded car batteries—a potential source of lead pollution—into new, long-lasting solar panels that provide emissions-free power. The system is based on a recent development in solar cells that makes use of a compound called perovskite.
As the oil and gas drilling technique called hydraulic fracturing (or “fracking”) proliferates, a new study on the contents of the fluids involved in the process raises concerns about several ingredients. Scientists say that out of nearly 200 commonly used compounds, there’s very little known about the potential health risks of about one-third, and eight are toxic to mammals.
A research team in Europe has achieved significantly increase in the yield of hydrogen produced by the photocatalytic splitting of water. Their breakthrough in light-driven generation of hydrogen was achieved by using a novel molecular shuttle to enhance charge-carrier transport with semiconductor nanocrystals.
Lawrence Livermore National Laboratory researchers have made a material that is 10 times stronger and stiffer than traditional aerogels of the same density. This ultra-low-density, ultra-high surface area bulk material with an interconnected nanotubular makeup could be used in catalysis, energy storage and conversion, thermal insulation, shock energy absorption and high energy density physics.
A catalyst made from a foamy form of copper has vastly different electrochemical properties from catalysts made with smooth copper in reactions involving carbon dioxide, a new study shows. The research, by scientists in Brown Univ.’s Center for the Capture and Conversion of CO2, suggests that copper foams could provide a new way of converting excess CO2 into useful industrial chemicals.
North Carolina State Univ. is part of a project team that is researching and developing new catalyst technology to produce the commercially important chemicals ethylene and propylene from natural gas. The project lead, Bio2Electric, LLC, dba EcoCatalytic Technologies, is collaborating with North Carolina State Univ., among other industry partners, to develop the new catalyst technologies.
As hemp makes a comeback in the U.S. after a decades-long ban on its cultivation, scientists are reporting that fibers from the plant can pack as much energy and power as graphene, long-touted as the model material for supercapacitors. A team has figured out how to make electrodes from certain hemp fibers, and the breakthrough came from figuring out how to process them.
It’s estimated that more than half of U.S. energy is wasted as heat. Mostly, this waste heat simply escapes into the air. But that’s beginning to change, thanks to thermoelectric innovators such as Massachusetts Institute of Technology’s Gang Chen. Thermoelectric materials convert temperature differences into electric voltage.
Researchers from Argonne National Laboratory and the Illinois Institute of Technology were awarded $2 million over the course of two years to fund studies on hybrid fuel cells from the Advanced Research Projects Agency – Energy. The research seeks to create a fuel cell that would both produce electricity and convert methane gas to ethane or ethylene that could then be converted to a liquid fuel or valuable chemicals.
Sun, wind and other renewable energy sources could make up a larger portion of the electricity America consumes if better batteries could be built to store the intermittent energy for cloudy, windless days. Now a new material could allow more utilities to store large amounts of renewable energy and make the nation's power system more reliable and resilient.
Taking fuel to Mars for return flights is heavy and expensive. The $1.9 billion Mars 2020 rover that NASA announced on Friday will include an experiment that will turn carbon dioxide in the Martian atmosphere into oxygen. It could then be used to make rocket fuel and for future astronauts to breathe. The device, named MOXIE, will make about three-quarters of an ounce of oxygen an hour.
Using a new method to track the electrochemical reactions in a common electric vehicle battery material under operating conditions, scientists at Brookhaven National Laboratory have revealed new insight into why fast charging inhibits this material's performance. The study also provides the first direct experimental evidence to support a particular model of the electrochemical reaction.
In a recent paper, a team at Stanford Univ. which includes materials science expert Yi Cui and 2011 R&D Magazine Scientist of the Year Steven Chu report that they have taken a big step toward accomplishing what battery designers have been trying to do for decades: design a pure lithium anode.
We already charge our toothbrushes and cellphones using contactless technology. Researchers in Germany have developed a particularly efficient and cost-effective inductive method that could allow electric cars to soon follow suit. The new design places the charging coils close to the car’s undercarriage without actually touching it. The charging station is also robust enough to be driven over.
American electric car maker Tesla Motors Inc. is teaming up with Japanese electronics company Panasonic Corp. to build a battery manufacturing plant in the U.S. expected to create 6,500 jobs. The companies announced the deal Thursday, but they did not say where in the U.S. the so-called "gigafactory," or large-scale plant, will be built.
Developed in the U.K., an innovative “trigeneration” system fuelled entirely by raw plant oils could have great potential for isolated homes and businesses operating outside grid systems. the small-scale combined cooling, heat and power system has been designed to utilize its waste heating by storing it through measures such as batteries and supercapacitors.
A hidden hazard lurks beneath many of the roughly 156,000 gas stations across the U.S. The hazard is corrosion in parts of underground gas storage tanks. In recent years, field inspectors in nine states have reported many rapidly corroding gas storage tank components such as sump pumps.
A powerful new tool that can help advance the genetic engineering of “fuel” crops for clean, green and renewable bioenergy, has been developed by researchers at the Joint BioEnergy Institute, a multi-institutional partnership led by Lawrence Berkeley National Laboratory.
