A new future opened
up by
ultra-high purity
hydrogen of
Ultra-
High Purity.
Ultra-high-purity hydrogen has enormous potential to bring next-generation scientific and technological innovations to industries such as semiconductors, medical equipment/devices, space engineering, and automobiles. We believe that our mission is to contribute to enriching people’s lives on the globe by commercializing the technology of Professor Matsumoto who has engaged in a research of hydrogen purification as a long-standing topic. We will continue to promote co-creation with like-minded companies and universities and pass on its results to the society from now on.
TECHNOLOGY
We adopted “VASA-
UHP,” the
cutting-
edge ultra-high purity
hydrogen purification
technology in the
industry.
We adopted “VASA-UHP,” the
cutting-edge ultra-high purity
hydrogen purification
technology in the industry.
In “VASA-UHP,” which is the ultra-high purity hydrogen purification technology that we engage in developing, we adopted a vanadium metal-based permeable membrane separation method. Its purification efficiency is higher than that of the existing PSA method, and there is no need for large-scale equipment or maintenance efforts for it. Moreover, not only the hydrogen recovery rate but also the durability of membranes and the amount of hydrogen purification are dramatically improved by employing VASA (vanadium superalloy) that combines the best of cutting-edge technologies for permeable membranes, which would have the potential to meet 99.9999% or more of the demand for ultra-high purity. In addition, palladium alloys were traditionally used for permeable membrane separation methods, but energy costs can be significantly reduced by replacing them with inexpensive vanadium superalloys.
Comparison of characteristics and features of various types of hydrogen permeable (separation) metal and alloy membranes
As compared with conventional PSA methods, the permeable membrane separation method can shorten the process, requires less maintenance efforts, and can make its equipment more compact. However, expensive palladium alloys have been used until now. By using vanadium superalloys, we can achieve high-purity purification in addition to reducing costs. Its durability that has been an issue can also be significantly improved.

Contributing to society
through hydrogen is the
mission of Ultra-High Purity.
Ａ solution to maximize the inherent “ability of vanadium to dissolve and permeate only hydrogen atoms/ions” and to overcome the challenges of improving its durability is “alloys.” UHP will meet current expectations of industrial circles seeking for ultra-high purity premium hydrogen through “VASA-UHP,” which is a unique purification technology using an alloy. We will continue to aim to establish not only refining technologies but also various breakthrough technologies toward carbon neutrality in the future. Please look forward to it.
ABOUT US
Ultra-High Purity is not a company that merely
pursues the success of its own business.
We believe that our mission is to contribute
to the advent of a hydrogen society in the future
where children can live with peace of mind through
the ultra-high purity hydrogen purification technology.
We will envision
a solid future for
a hydrogen society.
