Green-hydrogen is widely seen as a principle element of the emerging decarbonized economy.  But green-hydrogen’s scale-up faces three key hurdles:

  1. High production costs resulting from the high energy requirements of the freshwater electrolysis it is based on
  2. High transportation costs of compressing and shipping the hydrogen from the centralized scale electrolyzers that produce it to the distant industrial plants that consume it
  3. Unsustainable water use due to the thousands of liters of increasingly scarce freshwater resources consumed as feedstock for every kilogram of produced hydrogen

Purammon has developed a breakthrough technology that generates green-hydrogen from industrial wastewater instead of freshwater and that addresses all three of the above hurdles simultaneously

  1. Production costs: By leveraging contaminants within the wastewater, the system achieves dramatically better economics than conventional water electrolysis (up to 60% lower total OPEX per Kg hydrogen in lab studies).
  2. Transportation costs: The system completely avoids conventional green-hydrogen’s costly and environmentally problematic transportation.  Rather than being produced at a remote facility, our hydrogen is produced at the point of consumption (ie, the system is installed at an industrial plant that both consumes the produced hydrogen and provides the feedstock wastewater used to generate it).
  3. Freshwater resources:  Because its feedstock is wastewater and not clean water, the system has zero negative impact on local freshwater resources.  In fact, since the the contaminants in the wastewater are electrolyzed, our solution actually increases the local stock of clean water.


The technology is patent pending, is currently in TRL 6 prototype testing in Israel, and will be transitioning to first industrial scale pilot in 2023.  Please contact us for more information.
