NETL and Carnegie Mellon team up to create new paradigms for hydrogen production

28.01.2005


NETL and Carnegie Mellon develop new computational modeling tool

The Department of Energy’s National Energy Technology Laboratory (NETL) and Carnegie Mellon University have developed a new computational modeling tool that could make the production of hydrogen cheaper as the United States seeks to expand its portfolio of alternative energy supplies.

The research, supported by the DOE’s Office of Fossil Energy and reported in the current issue of the prestigious journal "Science" published by the American Association for the Advancement of Science, predicts hydrogen flux through metal alloy separation membranes that could be used to produce pure hydrogen.



"This research demonstrates our vision of coupling computational and experimental methods to facilitate rapid research and development of advanced technologies," said Anthony Cugini, focus area leader of Computational and Basic Sciences at NETL. "In essence, we are developing the computational tools to prescreen hydrogen separation membranes." These membranes allow pure hydrogen to pass through, while blocking impurities that are present with other gases in the production of hydrogen from fossil energy resources. Separation is a critical component of hydrogen production. Impurities lessen the effective use of hydrogen. Membranes have the ability to remove virtually all of the impurities from the hydrogen stream.

The use of advanced computing to determine the ability of candidate membranes to produce pure hydrogen would be a time- and money-saving step for hydrogen researchers. Instead of having to produce a large suite of alloys with various proportions of metals--such as palladium and copper--and then test them to determine optimum compositions for maximum hydrogen purification, they could predict in advance which compositions would have the desirable properties.

The research team at NETL in collaboration with Carnegie Mellon is investigating a new hydrogen membrane material--a copper palladium alloy--that allows hydrogen to be processed without contamination by other gases such as hydrogen sulfide during the purification process.

"We coupled computational modeling with experimental activity to develop a predictive model for hydrogen flux through copper palladium alloys," said David Sholl, associate professor in chemical engineering at Carnegie Mellon. "We now have a solid method in the screening of other complex alloys for the future production of hydrogen," he said.

"Ultimately, we see our new computational tools helping to take us into the new hydrogen economy as we scramble to harness this clean fuel, increasingly driven by our long-term worries about oil supplies as well as environmental challenges," Sholl said.

"Efficient techniques for large-scale purification of hydrogen are of world-wide interest as we work toward a hydrogen-based economy," said John Winslow, technology manager for Coal Fuels and Hydrogen at NETL. "If high flux membranes that resist chemical contamination can be developed, the impact of these devices on industrial hydrogen purification would be dramatic."

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Im Focus: Visual intelligence is not the same as IQ

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.

During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....

Im Focus: Researchers Develop Data Bus for Quantum Computer

The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.

Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
