Low Cost Green Hydrogen Production via Neutral Water Electrolysis and Polymer Cathode

Case ID:

This technology is a system for efficient and fast production of hydrogen by electrolysis of neutral water. This capability is in strong contrast to current systems, which operate with either highly acidic electrolytes or highly caustic media and require expensive or rare materials for the cathode. It is a cost-efficient and sustainable alternative that utilizes renewable solar energy and reduces emissions compared to traditional methods.

The global green hydrogen market is projected to grow from $676 million in 2022 to $7.34 billion by 2027, exhibiting a CAGR of 61% during the forecast period, which indicates a significant market opportunity for this innovation. The innovation has a wide range of applications, including long-term energy storage and offers a solution for production of green hydrogen for chemicals, transportation, power production, military and defense, metals production, and other industrial manufacturing.
