Energy Center to host two-day Hydrogen Symposium
April 15, 2009
The symposium will be held April 22-23 in Stewart Center. More than 15 presentations from industrial, governmental and academic leaders will center on the basic science of hydrogen; on production and storage; and on research into transportation uses.
"We are particularly pleased that we have been able to include discussions of hydrogen use in transportation in this year's symposium," said Jay Gore, director of the Energy Center. "We will explore state-of-the-art and future plans for hydrogen-fueled cars and space vehicles."
A featured speaker will be William Gerstenmaier, NASA associate administrator for space operations. NASA has been a pioneer in the use of hydrogen since the Apollo era. And its extensive use of hydrogen for the space shuttle program may be key to helping the United States move toward a clean-energy hydrogen economy.
"Having a chance to interact with a NASA administrator and learn from decades of experience with hydrogen-powered fuel cells and rocket engines is a great opportunity," said Timothee Pourpoint, research assistant professor of aeronautics and astronautics and symposium chair.
Gerstenmaier will discuss the space shuttle's use of hydrogen fuel for its main engines and the use of hydrogen as NASA transitions to Constellation, the next generation of space vehicles.
Purdue students can attend Gerstenmaier's talk and any of the other presentations free of charge. However, they must register in advance. Cost for Purdue faculty and staff is $50.

The recent recall of hoverboards because of exploding lithium-ion batteries highlights the danger of overheating batteries. Amy Marconnet, an assistant professor of mechanical engineering, can speak about the effects of excessive heating in batteries. Marconnet (pronounced mar-co-nay) founded the Marconnet Thermal and Energy Conversion Lab, where researchers are dissecting the batteries and testing materials making up electrodes and a critical component called a separator. (A video is available at https://www.youtube.com/watch?v=qCTMA8sxZO0) Battery failures have been reported in products ranging from commercial airliners and laptops to hoverboards and cellphones. Chemical reactions in the batteries generate heat while discharging and charging. The separator is a layer of material between the positive and negative electrodes. When it fails due to high heat, the battery short-circuits and could explode.Read Full Story
