HZI Alkaline Electrolysis
Green Hydrogen Production

Electrolyser Technology for Optimised Hydrogen Production

Hitachi Zosen Inova’s alkaline electrolyser is designed to convert water into hydrogen with the use of renewable electricity. As an advanced gaseous energy carrier, hydrogen is essential to help decarbonise mobility, industry and other energy sectors.

Leveraging our experience as system integrator, our proprietary electrolyser solutions are provided in standardised, modular configurations, and are fully integrated in customer’s infrastructures as a turnkey plant. Our overall proposal encompasses hydrogen production, compression, storage, and distribution for gas off-take. We are a partner of choice throughout the project life cycle, from feasibility study and permitting support to engineering, execution, commissioning, supervision, and O&M service of complex hydrogen plants. This broad spectrum coverage allows us to offer a unique and cost-competitive solution to optimise levelized cost of hydrogen.
HZI’s electrolyser technology offers optimised energy conversion efficiency, versatility and scalability. Our proprietary technology and design allows us to offer one of the most robust and efficient alkaline electrolysers available today. The result is consistently high hydrogen production, low power consumption and ≤ 99.999% of pure compressed and dry hydrogen, ideal for further compression, storage, or direct use.

Our standard single module consists of a 550 Nm³/h containerized unit, ready for outdoor installation. The plants are qualified for fully dynamic as well as continuous operation modes. They can operate as stand-alone or as a cluster to meet the required volumes of green hydrogen, up to multi-MW scale.
The scope HZI electrolyser consists of power supply, electrolysis, water treatment and gas upgrading. As optional downstream components such as compression, storage, trailer filling and dispensers can be offered as add on.
