Hydrogen Station Evaluation | Hydrogen Energy - HORIBA

We contribute to the safety, quality improvement and operational efficiency of hydrogen stations with its gas analyzers that can measure impurities in hydrogen in real time, analyzer for hydrogen in metals, and expertise in hydrogen-related equipment istallation.

Hydrogen stations, which are on the rise worldwide, come in two types: on-site and off-site. On-site hydrogen stations are equipped to produce hydrogen from city gas, LPG, etc., while off-site hydrogen stations do not have such facilities and use trailers to transport hydrogen produced outside to the hydrogen station. On-site and off-site hydrogen stations differ in the method of supplying hydrogen, but compression, storage, and dispensing mechanisms thereafter are the same, and countermeasures against impurity gases and hydrogen embrittlement are required.

Impurity Monitoring in Hydrogen Fuel Gas Production for FCVs

The expansion of hydrogen stations is necessary for the popularization of fuel cell vehicles (FCVs or FCEVs). ISO 14687-2 defines quality standards for hydrogen for FCVs and failing to comply with these standards leads to poisoning of the electrode catalysts of fuel cells, which can cause fuel cell degradation.
The purity of hydrogen supplied to FCVs is required by ISO to be at least 99.97%. When hydrogen is purified by reforming city gas at an on-site hydrogen station, impurities in the hydrogen has to be measured periodically.
We contribute to high-quality hydrogen production at on-site hydrogen stations with equipment that measures and monitors impurity gases (CO, CO2, sulfur components, etc.) in hydrogen in real time.

Monitoring Degradation of PSA Packing Material (Adsorbent)

To increase the purity of hydrogen to 99.97% or higher, the Pressure Swing Adsorption (PSA) method is used.
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.

Evaluation of Hydrogen Embrittlement in Metals

Hydrogen is stored in high-pressure tanks made of metal. Hydrogen under high pressure causes embrittlement of metals that come into contact with it (hydrogen embrittlement), which limits the metals that can be used to prevent leakage accidents and parts with quality compatible with the countermeasures and processing for compatibility are required. In particular, the higher the strength and the harder the steel, such as high-strength steel, the higher the susceptibility to hydrogen embrittlement.
Titanium, on the other hand, is being used as a hydrogen storage alloy.
HORIBA proposes an instrument to analyze hydrogen in metallic materials.
