Rencat technology

Ammonia for mobile applications

Cracking ammonia

Fertilizer-grade NH3 enters the compact cracker and H2+N2 with 10-50% NH3 exits, depending on operating conditions.



The mixture can be used as fuel for mobile applications, in ICE engines for automobile or shipping industry


  • Used as fertilizer and refrigerant
  • 6 times more compact than hydrogen stored at 200 bar
  • Low pressure storage and transportation
  • Ammonia is the only carbon-free high-density storage of H2
  • It can bring down the cost of H2 at the point of use by reducing storage and transportation cost

RenCat's innovative ammonia cracking unit is optimized to provide an ideal mixture for use as engine fuel.

Ammonia is difficult to combust, but when used in a mixture with hydrogen it can provide a clean alternative to fossil fuels for transportation purposes.

Currently RenCat is testing this solution for application in automotive.

RenCat cracking technology can provide fuel for automotive and shipping applications.

Ammonia for stationary applications


Cracking ammonia

Fertilizer-grade NH3 enters the cracking chamber of the reactor and H2+N2 with 500-1000 ppm NH3 exits.


Point of use

H2 obtained can be used directly for material processing or automotive applications or it can converted to electricity in fuel cells



Eliminating impurities

Trace ammonia is eliminated In the Selective Ammonia Oxidation (SAO) reactor, the output from the cracking chamber is mixed with air and the result is H2+ N2 with no trace ammonia.

RenCat’s innovative core technology is the invention of a mixed metal oxide catalyst which can remove trace ammonia impurity in hydrogen to the level of 0.1 ppm. The competitor technology is Pd based membrane which is very expensive and has stability problems.

For generating fuel cell grade hydrogen from ammonia, first it is converted to H2 through a reaction called cracking. The cracking reaction because of thermodynamic reasons, leaves a trace amount of ammonia unconverted. Because ammonia even in trace amounts is a poison for PEMFC, a purification step is needed after the cracking step.

Till now, an expensive and unreliable Pd-membrane based technology has been the way to clean the trace ammonia from the cracked product making H2 generation from ammonia unfeasible.

Rencat uses a non-noble metal catalysts for hydrogen generation and an abundant inexpensive metal oxide to purify the hydrogen. The patented technology generate a PEMFC quality H2 by selectively oxidising all trace ammonia from the H2 containing stream via a process called selective ammonia oxidation (SAO).

Not only that, through extensive research in Rencat has reduced the cost for the cracking step by replacing noble and expensive Ru by abundant and inexpensive FeNi alloy.

RenCat ammonia to H2 generation technology is here to drastically reduce the price and accessibility of fuel cell power.

Because of the  use of very inexpensive metal oxides and metal alloys as catalyst, the price of H2 generator will be at least an order of magnitude lower compared to the Pd-membrane based system.
