Eden Energy Advances Practicality of Hydrogen Cars

 Patented New Energy Storage System Is Smaller and More Efficient

 

Littleton, CO--Eden Energy Ltd. (ASX:EDE), through its wholly-owned U.S.
subsidiary Hythane Company LLC, today announced it has received a U.S.
patent <http://www.ccapreview.com/cca/pat7305836.pdf>  for its cryogenic
storage vessels for liquid hydrogen.  Among the applications, the new
technology will advance the practicality of hydrogen cars by optimizing
energy storage, reducing or eliminating the need for bulky lithium ion
batteries.

 

The main use for this technology, called Superconducting Magnetic Energy
Storage (SMES), will be in the automotive industry.  Whether used for
traditional hybrids, electric cars, or hydrogen combustion engines, SMES
will capture and use energy from the vehicle braking system to reduce or
eliminate the use of large, expensive batteries.  By combining fuel
storage and the battery into a single unit, the range and efficiency of
alternative fuel vehicles will be increased, and fuel can be stored in a
much smaller space.

 

"This technology addresses many of the barriers to popular use of
alternative fuels, such as hydrogen," said Greg Egan, Chief Technology
Officer at the Hythane Company and inventor of the SMES system.  "By
increasing the range and efficiency of hybrid, electric, and hydrogen
powered vehicles, SMES has immediate uses today.  It also brings us a
big step closer to the practical use of pure hydrogen."

 

The innovation of SMES is that the vehicle fuel tank becomes a storage
device to capture electrical energy from a regenerative braking system
or other engine generation system, reducing or eliminating the need for
on-board batteries.  Integrating the SMES system with a liquid cryogenic
fuel tank enables superconductivity, providing frictionless energy
storage.

 

"This is another example of how Eden Energy is creating real-world
solutions that will take us onto the hydrogen highway," said Gregory
Solomon, Chairman and CEO of Eden Energy.  "We are very fortunate to
have the finest minds in the world at Eden Energy, working to bring the
benefits of clean, renewable energy from promise to reality."  On a
larger scale, the technology can provide a system for transporting both
electricity and liquid hydrogen from renewable energy sites to markets,
when connection to the power grid is not possible.
