Hydrogen Generator

Technology / Service Summary

HydroSpring is an onsite hydrogen generator that electrolyzes water to generate and supply high-purity hydrogen gas to contribute to the realization of a hydrogen-based society.


Electrolyzes water using renewable energy to generate and supply H2 gas.


① High safety and convenience
On-site/on-time production of hydrogen using only electricity and water
② High efficiency and load fluctuation followability
③ Manufactures high quality hydrogen
Manufactures hydrogen with a purity of 99.9% to 99.999%
④ Easy and secure operability
Automatic operation through a remote monitoring system.


Since this is a built-in portable container type, there is no need to construct a new building, realizing an easy outdoor installation. At the same time, it achieves simplification and cost reduction of on-site construction.
