| Storage: Linde Develops Ionic Compressor for More Efficient Compressed
Hydrogen Storage
VIENNA - Large-volume storage of compressed hydrogen gas is likely to
become simpler, cheaper, more efficient and less maintenance-intensive
with the development of a so-called ionic compressor at an r&d center
operated here by Linde Gas, the industrial gas company.

Great. Now where will the hydrogen come from?

Ceramic microreactors developed for on-site hydrogen production
Publication Date:19-September-2006

CHAMPAIGN, Ill. -- Scientists at the university of Illinois at
Urbana-Champaign have designed and built ceramic microreactors for the
on-site reforming of hydrocarbon fuels, such as propane, into hydrogen
for use in fuel cells and other portable power sources. Applications
include power supplies for small appliances and laptop computers, and
on-site rechargers for battery packs used by the military.
"The catalytic reforming of hydrocarbon fuels offers a nice solution to
supplying hydrogen to fuel cells while avoiding safety and storage
issues related to gaseous hydrogen," said Paul Kenis, a professor of
chemical and biomolecular engineering at Illinois and corresponding
author of a paper accepted for publication in the journal Lab on a
Chip, and posted on its Web site.
In previous work, Kenis and colleagues developed an integrated catalyst
structure and placed it inside a stainless steel housing, where it
successfully stripped hydrogen from ammonia at temperatures up to 500
degrees Celsius.
In their latest work, the researchers incorporated the catalyst
structure within a ceramic housing, which enabled the steam reforming
of propane at operating temperatures up to 1,000 degrees Celsius. Using
the new ceramic housing, the researchers also demonstrated the
successful decomposition of ammonia at temperatures up to 1,000 degrees
Celsius. High-temperature operation is essential for peak performance
in microreactors, said Kenis, who also is a researcher at the
university's Beckman Institute for Advanced Science and Technology.
When reforming hydrocarbons such as propane, temperatures above 800
degrees Celsius prevent the formation of soot that can foul the
catalyst surface and reduce performance.
"The performance of our integrated, high-temperature microreactors
surpasses that of other fuel reformer systems," Kenis said. "Our
microreactors are superior in both hydrogen production and in long-term
stability." Kenis and his group are now attempting to reform other,
higher hydrocarbon fuels, such as gasoline and diesel, which have
well-developed distribution networks around the world.
The research team includes Kenis and graduate students Michael Mitchell
and Christian. Funding was provided by the U.S. Department of Defense,
Army Research Office, National Science Foundation and the U. of I.

Like I wrote here some weeks ago.
Hydrogen storage is a nonsens.
Better to have a reformer system

So let me get this righ. You drill for oil. The you refine it. Then you
store it. Then you transport it. Then you convert it to H2. Then you use
the H2 as fuel. Ok what am I missing here? Isn't there something about the
more steps in a process the lower the efficiency of the process?

ThyssenKrupp to deliver two fuel cell submarines to German Navy
Publication Date:26-September-2006

Source:AFX
FRANKFURT --ThyssenKrupp AG's Technologies said it hass secured a
government contract to supply the German Navy with two fuel cell
submarines. The company declined to comment on the value of the
contract.
Fuel cell submarines can lurk under water invisibly for three weeks at
a time.
ThyssenKrupp said the submarines are due to be delivered in 2012 and
2013.
