Researchers Partner with Start-Up on Natural Gas to Hydrogen and Carbon Fiber Technology
-
John Hu
The availability of unprecedented volumes of shale gas resources present a significant opportunity to develop completely new processes for hydrogen generation.
“Long-term trends show a preference for non-carbon forms of energy. Hydrogen appears to be the most promising and environmentally benign energy source, since it can be converted into electricity and other energy forms with less pollution and high efficiency,” said John Hu, Statler Chair in Engineering for Natural Gas Utilization. “However, the objectives of reduced carbon emissions and enhanced use of hydrogen for fuel are in direct conflict as the most commercially viable method for hydrogen production from natural gas via steam methane reforming, produces large amounts of carbon dioxide.”
Hu’s group at WVU recently reported a promising new catalyst innovation for non-oxidative thermochemical conversion of methane to CO2-free hydrogen and solid carbon nanotubes. The catalysis promotes “base growth” carbon nanotube formation rather than the current “tip growth” technology. Base growth formation enables the catalyst to regenerate while also creating a highly pure and crystalline carbon product. The reaction conditions can be optimized to tune the diameter and length of the CNTs produced. WVU brings catalyst and process background-related intellectual property to the project.
The goal of the partnership, which is being led by C4-MCP, LLC, a Santa Monica, California-based technology start-up, is to offset the hydrogen production costs with the sales of carbon fiber and CNTs, reducing the hydrogen’s net cost to under $2 per kilogram. This will help make hydrogen-fueled cars and trucks cost-competitive with conventional gasoline and diesel vehicles and will virtually eliminate CO2 emissions from the methane-to-hydrogen process. The carbon fiber can also be used in various medical device, aerospace and building products.
PNNL will assist WVU in the evaluation of its new process while performing independent bench scale process evaluations to further develop the catalytic system. The work could ultimately lead to a commercial-scale process.
“The catalytic materials developed and reaction mechanisms evaluated in this study will guide other hydrogen materials selection and innovation,” Hu said.
The work is being funded by the U.S. Department of Energy's Fuel Cell Technologies Office.

Scientists deepen understanding of the magnetic fields that surround the Earth and other planets
Now, a team of scientists has completed research into waves that travel through the magnetosphere, deepening understanding of the region and its interaction with our own planet, and opening up new ways to study other planets across the galaxy.
Light dark matter is a thousand times less likely to bump into regular matter than previous astrophysical analyses allowed
A team led by scientists from the Department of Energy's SLAC National Accelerator Laboratory and Stanford University has narrowed down how strongly dark matter particles might interact with normal matter. Based on the number and distribution of small satellite galaxies seen orbiting our Milky Way, the team found this interaction to be at least a thousand times weaker than the strongest interaction allowed by previous astrophysical analyses.
New Sensor Could Shake Up Earthquake Response Efforts
An optical sensor developed at Berkeley Lab could speed up the time it takes to evaluate whether buildings are safe to occupy after a major earthquake. After four years of extensive peer-reviewed research and simulative testing at the University of Nevada's Earthquake Engineering Laboratory, the Discrete Diode Position Sensor (DDPS) will be deployed for the first time this summer in a multi-story building at Berkeley Lab - which sits adjacent to the Hayward Fault, considered one of the most dangerous faults in the United States.
The best of both worlds: how to solve real problems on modern quantum computers
Researchers at the U.S. Department of Energy's (DOE) Argonne National Laboratory and Los Alamos National Laboratory, along with researchers at Clemson University and Fujitsu Laboratories of America, have developed hybrid algorithms to run on size-limited quantum machines and have demonstrated them for practical applications.
Designer proteins form wires and lattices on mineral surface
This research is a fundamental discovery of how to engineer proteins onto non-biological surfaces. Artificial proteins engineered from scratch have been assembled into nanorod arrays, designer filaments and honeycomb lattices on the surface of mica, demonstrating control over the way proteins interact with surfaces to form complex structures previously seen only in natural protein systems. The study provides a foundation for understanding how protein-crystal interactions can be systematically programmed and sets the stage for designing novel protein-inorganic hybrid materials.
Giving nanowires a DNA-like twist
Argonne National Laboratory played a critical role in the discovery of a DNA-like twisted crystal structure created with a germanium sulfide nanowire, also known as a "van der Waals material." Researchers can tailor these nanowires in many different ways -- twist periods from two to twenty micrometers, lengths up to hundreds of micrometers, and radial dimensions from several hundred nanometers to about ten micrometers. By this means, they can adjust the electrical and optical properties to optimize performance for different applications.

Augustana University Professor's Research Leads to Surprising Mating Decision in Butterfly Species
The males of one species of butterfly are more attracted to females that are active, not necessarily what they look like, according to a recent research conducted at Augustana University.The paper, "Behaviour before beauty: Signal weighting during mate selection in the butterfly Papilio polytes," found that males of the species noticed the activity levels of potential female mates, not their markings.

Bursts of Light Shape Walls Between Waves of Charge
To better store data, scientists need ways to change a material's properties suddenly. For example, they want a material that can go from insulator to conductor and back again. Now, they devised a surprisingly simple way of flipping a material from one state into another, and back again, with flashes of light. A single light pulse turns thin sheets of tantalum disulfide from its original (alpha) state into a mixture of alpha and beta states. Domain walls separate the two states. A second pulse of light dissolves the walls, and the material returns to its original state.
Deep Learning Reveals Mysteries of Deep Space
How do you determine the measurable "things" that describe the nature of our universe? To answer that question, researchers used CosmoFlow, a deep learning technique, running on a National Energy Research Scientific Computing Center supercomputer.

The team showed that CosmoFlow offers a new platform to gain a deeper understanding of the universe.
