The hydrogen stations, both onsite and offsite, are on the rise worldwide. On-site hydrogen stations are equipped with facilities to produce hydrogen from city gas, LPG, etc., while off-site hydrogen stations do not have such facilities, but use trailers to transport hydrogen produced outside to the hydrogen station.
On-site and off-site hydrogen stations differ in the way they supply hydrogen, but the mechanisms for compression, storage, and dispensing are the same, and measures are required to prevent impurity gases and hydrogen embrittlement.

The expansion of hydrogen stations is necessary for the widespread use of FCEVs (fuel cell electric vehicles), and if the quality standards for hydrogen for FCEVs ISO 14687-2 defines are not followed, the electrocatalyst of the battery fuel cell will be poisoned, causing the fuel cell to deteriorate.
The purity of hydrogen to be supplied to FCEVs is specified by ISO as 99.97% or higher, and when city gas is reformed at on-site hydrogen stations to refine hydrogen, the impurities contained in the hydrogen must be measured periodically.
With devices that measure and monitor impurity gases (CO, CO2, sulfur components, etc.) in hydrogen in real time, we contribute to high quality hydrogen production at on-site hydrogen stations.
Among the hydrogen produced, the demand for hydrogen for fuel cell applications is particularly on the rise. Among other things, hydrogen for FCEVs is required by ISO to be 99.97% or higher, and each impurity concentration standard is set. In order to ensure this purity, it is necessary to increase the hydrogen purity using the Pressure Swing Adsorption (PSA) method.
We provide a solution by measuring the concentration of impurities in hydrogen that contributes to monitoring the deterioration of adsorbents and other materials used in PSA.
Metal high-pressure tanks are used to "carry" and "store" hydrogen, but hydrogen managed at high pressure can be "brittle" (hydrogen embrittlement) to the metals it comes in contact with. Therefore, the metals that can be used are limited in order to prevent accidents due to leaks, and parts that have the quality to comply with the measures and processing to comply with them are required. The susceptibility to hydrogen embrittlement is particularly high for high strength and hard steels.
On the other hand, titanium is also being used as a hydrogen storage alloy, and HORIBA proposes a device to analyze hydrogen in metallic materials.
We can also propose material, structural, and degradation evaluations for Carbon Fiber Reinforced Plastic (CFRP), which strengthens the structure of hydrogen tanks, and for resins that do not embrittle.
For solutions for CFRP and resin evaluation, We can offer a wide range of solutions depending on the application. Please contact us for the details.
We have a long-standing commitment to complimentary sample analysis towards the evaluation of advanced materials. Each submission is measured by a highly-trained member of the Applications Lab and presented as a formal lab report complete with method, observations, results, and data interpretation assistance.
With the turnkey solution, which is a total package for the construction of laboratory buildings, we take care of the entire construction work in place of busy customers right up to the start of laboratory operation, while taking into consideration the ordering of multiple vendors, meetings to determine specifications, safety, process, and quality control of construction, as well as operation, maintenance, and high efficiency of work after installation, and emphasizing safety and usability.
We have developed a unique risk assessment method that eliminates omissions and leakages even at points that are difficult to notice, by utilizing the knowledge accumulated by HORIBA FuelCon, a company specializing in turnkey solutions, engineering, and fuel cell evaluation, in order to achieve both cost and time minimization as well as safety and security.
