Helping Hydrogen: Student Inventor Tackles Challenge of Hydrogen Storage
$30,000 Lemelson-MIT Collegiate Student Prizes
Awarded to Inventive Students Nationwide; Four Leading
Institutes Celebrate 2010 Winners
Determined to play a key role in solving global dependency
on fossil fuels, Javad Rafiee, a doctoral student in the
Department of Mechanical, Aerospace, and Nuclear Engineering at
Rensselaer Polytechnic Institute, has developed a new method
for storing hydrogen at room temperature.
Rafiee has created a novel form of engineered graphene that
exhibits hydrogen storing capacity far exceeding any other
known material. For this innovation, which brings the world a
step closer to realizing the widespread adoption of clean,
abundant hydrogen as a fuel for transportation vehicles, Rafiee
is the winner of the 2010 $30,000 Lemelson-MIT Rensselaer
Student Prize. He is among the four 2010 $30,000 Lemelson-MIT
Collegiate Student Prize winners announced today.
“Invention is the key ingredient of progress, and the
Lemelson-MIT Rensselaer Student Prize rallies our students to
innovate world-changing solutions for the grand challenges
facing all people of all nations,” said Rensselaer President
Shirley Ann Jackson. “Javad Rafiee has the vision of a robust
national hydrogen economy and a world less dependent on oil and
gasoline. I applaud his efforts toward this noble goal, and
congratulate him on this prestigious award. I thank all of the
Lemelson-MIT Rensselaer Collegiate Student Prize winners and
finalists for their effort, zeal, and for being ambassadors of
progress.”
Rafiee is the fourth recipient of the Lemelson-MIT
Rensselaer Student Prize. The prize, first given in 2007, is
awarded annually to a Rensselaer senior or graduate student who
has created or improved a product or process, applied a
technology in a new way, redesigned a system, or demonstrated
remarkable inventiveness in other ways.
"This year’s winners from the Massachusetts Institute of
Technology, California Institute of Technology, Rensselaer
Polytechnic Institute, and University of Illinois at
Urbana-Champaign shine light on the significance of collegiate
invention. They have the ability to transform seemingly
implausible ideas into reality and are the true entrepreneurial
leaders of their generation,” said Joshua Schuler, executive
director of the Lemelson-MIT
Program.

Enabling Greener Transportation with Graphene
Hydrogen storage has proven to be a significant
bottleneck to the advancement and proliferation of fuel cell
and hydrogen technologies in cars, trucks, and other
applications. Rafiee has developed a new method for
manufacturing and using graphene, an atom-thick sheet of carbon
atoms arranged like a nanoscale chain-link fence, to store
hydrogen. His solution is inexpensive and easy to produce.
With adviser and Rensselaer Professor Nikhil Koratkar, Rafiee
used a combination of mechanical grinding, plasma treatment,
and annealing to engineer the atomic structure of graphene to
maximize its hydrogen storage capacity. This new graphene has
exhibited a hydrogen storage capacity of 14 percent by weight
at room temperature – far exceeding any other known
material.
This 14-percent capacity surpasses the U.S. Department of
Energy 2015 target of realizing a material with hydrogen
storage capacity of 9 percent by weight at room temperature.
Rafiee said his graphene is also one of the first known
materials to surpass the Department of Energy’s 2010 target of
6 percent.
Rafiee’s graphene exhibits three critical attributes that
result in its unique hydrogen storage capacity. The first is
high surface area. Graphene’s unique structure, only one atom
thick, means that each of its carbon atoms is exposed to the
environment and, in turn, to the hydrogen gas. The second
attribute is low density. Graphene has one of the highest
surface area-per-unit masses in nature, far superior to even
carbon nanotubes and fullerenes.
The third attribute is favorable surface chemistry. After
oxidizing graphite powder and mechanically grinding the
resulting graphite oxide, Rafiee synthesized the graphene by
thermal shock followed by annealing and exposure to argon
plasma. These treatments play an important role in increasing
the binding energy of hydrogen to the graphene surface at room
temperature, as hydrogen tends to cluster and layer around
carbon atoms.
Talented Engineer
Rafiee joined Rensselaer in 2008, following an
internship at the City University of Hong Kong and earning his
bachelor’s and master’s degrees in mechanical and manufacturing
engineering from the University of Tabriz in Iran. At
Rensselaer, Rafiee and his brother, Mohammad, joined the
research group of Mechanical, Aerospace, and
Nuclear Engineering Professor Nikhil Koratkar.
“Javad is extremely knowledgeable, has great confidence in
his abilities, and has demonstrated a very high level of
creativity and originality. However, it is his deep passion and
enthusiasm for research and discovery coupled with his amazing
drive and energy that differentiates him from his peers,”
Koratkar said. “This passion and excitement for discovery and
innovation is not something that can be taught or learned. It
is an intrinsic quality of an individual – either you have it
or you don’t — and Javad is the most intellectually curious
student I have ever had the privilege to advise here at
Rensselaer.”
In his time at Rensselaer, Rafiee has authored five, and
co-authored three, journal papers in various disciplines,
ranging from materials science and mechanical engineering, to
computer science and urology.
Rafiee is from Tehran, Iran, and expects to earn his
doctorate in 2011. Following graduation, he and his brother
plan to start their own business with a focus on clean energy
and green manufacturing.

were announced today at their respective universities:
-
Lemelson-MIT
Student Prize winner Erez Lieberman-Aiden demonstrated
creativity and innovation across several disciplines, most
recently with his invention of “Hi-C”, a three-dimensional
genome sequencing method that will enable an entirely new
understanding of cell state, genetic regulation and
disease.
-

ABOUT THE LEMELSON-MIT PROGRAM
celebrating innovation, inspiring youth
The Lemelson-MIT Program recognizes the outstanding
inventors and innovators transforming our world, and inspires
young people to pursue creative lives and careers through
innovation.
Jerome H. Lemelson, one of U.S. history’s most prolific
inventors, and his wife, Dorothy, founded the Lemelson-MIT
Program at the Massachusetts Institute of Technology in 1994.
