Shale oil dividend could pay for smaller carbon footprint

August 19, 2014 8:16 am | by Natalie van Hoose, Purdue Univ. | News | Comments

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.

Bionic liquids from lignin

August 19, 2014 7:44 am | by Lynn Yarris, Lawrence Berkeley National Laboratory | News | Comments

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.

Why the hydrogen fuel cell vehicle rollout may now succeed

August 18, 2014 10:42 am | by Kat Kerlin, UC Davis News Service | News | Comments

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.

Recycling old batteries into solar cells

August 18, 2014 7:38 am | by David L. Chandler, MIT News Office | News | Comments

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.

A new look at what’s in “fracking” fluids raises red flags

August 15, 2014 9:23 am | News | Comments

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.

Could hemp nanosheets topple graphene for making the ideal supercapacitor?

August 12, 2014 12:34 pm | News | Comments

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.

Running on waste heat

August 11, 2014 7:36 am | by Rob Matheson, MIT News Office | News | Comments

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.

Turning methane into usable liquid fuel

August 5, 2014 8:48 am | by Louise Lerner, Argonne National Laboratory | News | Comments

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.

“Wetting” a battery’s appetite for renewable energy storage

August 4, 2014 9:22 am | by Frances White, PNNL | Videos | Comments

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.

NASA to test making rocket fuel on Mars

August 4, 2014 8:16 am | News | Comments

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.
