Eden Energy Ltd. through its wholly-owned U.S. subsidiary Hythane Company LLC, has announced it has received a U.S. patent 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.
