Overview

Hydrogen is vital for decarbonizing hard-to-abate sectors, and water electrolysis—especially with renewable power—offers a clean way to produce ultra-pure hydrogen. Alkaline water electrolysis is mature and economical but still limited by moderate performance and costly electrode materials. New advances in non-noble catalysts, nanostructured electrodes, and improved diaphragms aim to cut costs and boost efficiency, yet hydrogen production remains energy intensive. Aligning with India’s National Hydrogen Mission, we are working int the design and development of 1kW- 10 kW alkaline electrolyzer using low-cost, indigenously developed stainless-steel electrodes to scale our proven 

lab prototype into a durable, modular system.

 

Key Features

  • Indigenous, Low-cost and durable electrode technology
  • Optimized electrochemical performance
  • Scalable and modular system architecture
  • Cost-effective, locally fabricated components

Potential Applications

  • Renewable energy integration & Storage
  • Hydrogen for mobility
  • Green ammonia and Fertilizer production
  • Decarbonization of Industrial processes

Status

  • Developed durable and cost-effective Indigenous electrodes (cathode, anode, and bipolar plates) using a wet chemical process.  A stability assessment was conducted at a high current density of 100 mA/cm² over a duration of 5 h and the linear sweep voltammetry didn’t show much difference.
  • Designed the number of cells for the 1 kW electrolyzer stack, based on the desired voltage and current. Developed Gravity based gas-liquid separator and integrated with 1kW stack for the separation of gases (H2 & O2) and liquid
  • Demonstrated the indigenously developed alkaline electrolyzer with 0.1NM3/hour of Hydrogen production.
