The control of power flow in power systems is a major concern for utilities and system operators. But full power flow control has been prohibitively expensive, requiring large numbers of complicated and costly devices. As a result, power systems almost always operate sub-optimally at billions of dollars per year. A simple, magnetic-field-based valve-like device for power flow control, the Continuously Variable Series Reactor (CVSR), developed by Oak Ridge National Laboratory, SPX Transformer Solutions Inc. and the Univ. of Tennessee, has introduced substantial improvements.
Pacific Northwest National Laboratory’s Solar Thermochemical Advanced Reactor System (STARS) addresses a major criticism of solar energy, which, like wind power, can’t provide continuous output. Because of its design, STARS doesn’t require power plants to cease operations when the sun sets or clouds cover the sky.
Wind energy pricing is at an all-time low, according to a new report released by the U.S. Dept. of Energy and prepared by Lawrence Berkeley National Laboratory. The prices offered by wind projects to utility purchasers averaged just $25/MWh for projects negotiating contracts in 2013, spurring demand for wind energy.
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.

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.
