Alkaline Water Electrolyser Plant

The alkaline water electrolyser plant consist of a compact, zero gap, bipolar type configuration cell module stack with high current density porous nickel electrodes. The product gases at the stack exit are conditioned and purified to meet the specific user demands. Demineralised water, electricity and chilled water are the only inputs required for the operation of this plant. The plant is capable of producing high quality hydrogen and oxygen gases and has yielded good performance in sustained long duration operations. The process can be easily scaled up or scaled down to suit the user requirements.

INTRODUCTION

Alkaline water electrolysis plant is a simple one step process wherein water is split using DC electricity into pure hydrogen and oxygen gases. This plant consists of a electrolyser cell module stack integrated with a process skid for purification and conditioning of the product gases as per user's technical specifications.

Advantages

This green process is simple and includes just one step reaction without generation of any hydrocarbons or other impurities as by-products. The system requires only DM water, chilled water and electricity during operation. It is an energy efficient system and can also serve as an inexpensive import substitution. The plant is very compact enabling high gas production rates in lesser floor space. The production rates can be varied easily for on-demand requirements. The design of plant and SCADA system is such that the operation of plant is safe, reliable and user friendly with minimum manual intervention.

APPLICATIONS

The hydrogen produced by this system can be used in industries like fertilizers, pharmaceuticals, metallurgical operations and food, telecom and fuel cell, etc. It also finds varied applications in laboratory based experiments. The byproduct oxygen can substitute oxygen cylinders in hospitals for reliable and on demand supply of oxygen. It can also be used in emergency shelters employed in hazardous process industries.
