132kW Hydrogen Compressor for Energy Storage Systems

Overview

DW-6.8 (1.5-2.5)-33 Hydrogen Compressor for Energy Storage Systems

The DW-6.8 (1.5-2.5)-33 Hydrogen Compressor is designed for hydrogen boosting in energy storage systems, renewable energy projects, and industrial hydrogen utilization processes.

Different from high-pressure hydrogen filling compressors, this model focuses on increasing hydrogen pressure from low-pressure sources to meet the requirements of storage, circulation, and downstream utilization systems.

The compressor is suitable for pure hydrogen compression with a flow capacity of 980 Nm³/h. It operates with an inlet pressure of 0.15~0.25 MPa.G and increases hydrogen pressure up to 3.3 MPa.G. Driven by a 132 kW motor, unit adopts a water-cooled reciprocating piston compression system for continuous industrial operation.

With its medium-capacity hydrogen handling capability, the DW-6.8 (1.5-2.5)-33 provides a practical compression solution for hydrogen energy storage facilities, hydrogen production projects, and industrial hydrogen supply systems.

Design Features

The compressor is designed for hydrogen sources with relatively low inlet pressure, providing efficient pressure increase for storage and utilization systems.

Reciprocating Piston Compression Technology

The piston compression structure provides stable gas displacement and is suitable for continuous hydrogen boosting processes.

Water-Cooled Operation

The cooling system helps maintain operating temperature during long-duration compression service.

Balanced Mechanical Structure

The symmetrical balanced design helps reduce vibration during operation and improves mechanical stability.

Engineering Advantages

Designed specifically for hydrogen energy storage applications	Suitable for continuous hydrogen circulation and boosting processes	Supports medium-capacity hydrogen handling requirements	Provides reliable pressure control between hydrogen production and utilization systems
