PRODUCT
Hydrogen Storage Alloys What is (Metal Hydride: MH)?
Because this material can store hydrogen in a chemically stable form, it has the following characteristics, which distinguish it from conventional high-pressure gas and liquid hydrogen systems:
"Safety"
・Hydrogen can be absorbed and released at low pressure, making it safe to handle
・Since it is stored in a chemically stable state, any hydrogen leaks can be minimized
"Space-Saving Storage"
・Because it can store hydrogen at high densities, it allows for more space-efficient storage facilities.
"Long-Term Storage"
・Since hydrogen is stored stably as a hydride, it can be stored safely for long periods.

PROBLEM
Do you ever face challenges like these?
- I’d like to use hydrogen, but high-pressure gas and liquid hydrogen require compliance with legal regulations and special equipment, so I can’t handle them.
- High-pressure gases and liquid hydrogen take up a lot of storage space and get in the way
- We want to store and use hydrogen in a way that suits our application.
- I want to store even more hydrogen.

Mitsui Kinzoku's Unique Strengths That Set Us Apart from the Competition

#01 Over 30 Years of Proven Quality in Automotive Applications
With over 30 years of experience in manufacturing and supplying products for the automotive industry, our reliability is among the highest in the industry. We possess technical expertise honed in environments with stringent quality requirements.

#02 Customization Capabilities to Meet Customer Needs
Rather than offering products that conform to a single standard, we can design and develop products tailored to our customers’ specific requirements, such as sorption pressure, flatness (release pressure gradient), and the presence or absence of cobalt.

#03 “Ease of Use” with an Eye on Legal Compliance
Another feature is that the barriers to adoption are lower than those for systems using high-pressure gas or liquid hydrogen.
FEATURES
Material Characteristics
Hydrogen Storage Alloys ...delivers optimal performance across a wide range of applications. The two features are as follows.
01
Can be stored from various hydrogen sources
It supports a variety of hydrogen sources and enables flexible storage tailored to specific applications.
Furthermore, it can be handled safely and easily even under conditions of temperatures below 100°C and low pressure.

02
Easy-to-Use Hydrogen Storage Methods
Because hydrogen can be safely stored and released under low pressure and at temperatures close to room temperature, it can be operated outside the scope of the High-Pressure Gas Safety Act.
This storage method requires no special equipment, such as compression or cooling systems, making it easy to implement and use.

LINE UP
Mitsui's Metal Hydride Lineups
We provide five types of Metal hydride. These have different characteristics in terms of hydrogen absorption, suitable pressure, durability and material composition.You can choose a Metal hydride type based on your application, legal compliance requirements, and storage environment. We also offer customization to meet your specific requirements.Please contact us for details.
