Wastewater to Green Hydrogen Electrolysis

Purammon's W2toH2 electrolyzer produces green hydrogen using wastewater instead of freshwater as the feedstock. This breakthrough is a major environmental win-win-win, simultaneously reducing:

hydrogen production costs

wastewater treatment costs, and

the customer's carbon footprint.

W2toH2 exploits the chemical energy locked in

wastewater contaminants to enable hydrogen generation with 15%-20% less electrical energy than conventional water electrolysis systems ... and "for the same price", it simultaneously removes those contaminants from the wastewater!

​Wastewater Electrolysis Structure

Leveraging Purammon's unique expertise in wastewater electrocatalysis, the patent pending W2toH2 reactor uses an asymmetrical feed (wastewater to the anode/H2SO4 to the cathode) to simultaneously oxidize and treat the wastewater on the anodic side while exploiting its electrochemical properties to lower the energy requirement of producing hydrogen on the cathodic side. 

Significantly lower power consumption than conventional water electrolysis.

Eliminates existing wastewater treatment costs (wastewater purification is a "free side effect" of the H2 generation).

No impact on freshwater resources.

Small modular technology enables onsite installation and avoids hydrogen transportation - the same customer that produces the wastewater can consume the resulting hydrogen.

Enables significant reduction of industrial plant carbon footprint without significant process modifications.

Advantages include:

White tech background

In addition to its unique capabilities in electrolyzing wastewater, Purammon has pioneered an innovation that significantly lowers the energy requirements of electrolyzing freshwater.

 

Conventional polymer electrolyte membrane water electrolysis (PEMWE) cells consists of a solid electrolyte ion-conducting membrane pressed between the anode and cathode and enclosed by bipolar current collectors.
