Liquid Battery

Overview:

The uniqie technology incorporates hydrogen into a proprietary "carrier liquid," capable of holding massive amounts of hydrogen. The liquid later releases the hydrogen on demand at the point of use, e.g., within a vehicle or power system,  The depleted carrier liquid can then be reprocessed for reuse.  One cubic centimeter of the liquid can store up to 700 cc of hydrogen gas (STP).  A typical gas tank of carrier liquid can hold 5kg of hydrogen, enough for the full range of a fuel cell vehicle.

When paired with a fuel cell, the liquid carrier technology has three times the energy density of a lithium ion battery.  Unlike direct methanol fuel cell systems, the liquid carrier technology does not produce any CO2 and is therefore safer for confined spaces.

Benefits:

  • Closes the loop from green hydrogen production to use with 100% re-used carrier and components
  • Huge potential market as hydrogen begins to replace conventional fuels 
  • Superior tank fill speed
  • Excellent volumetric hydrogen storage
  • Superior Safety
  • Full suite of hydrogen economy patents are available
  • Applications include all automotive, truck, bus, forklift, power tools, fuel cell, battery replacement, hydrogen storage, purge and transportation as well as power backup systems
