Overview

A compact hydrogen generator of the HYSERVE series is a low-cost, space-saving device that can easily generate high-purity hydrogen on site, leveraging Osaka Gas’s years of experience in high-performance catalyst technology. It uses city gas, LPG, carbon-neutral methane generated from biogas, and the like as raw materials.

■Awards received in relation to HYSERVE

　・Japan Gas Association Technology Award (FY2006, from Japan Gas Association)

　・Osaka Environmental Award (FY2005, from Osaka Prefectural Assembly)

　・24th Engineering Merit Award (FY2004, from the Engineering Advancement Association of Japan)

Features

1. Compact Package Design
　・The reforming and purification systems are packaged inside one unit to significantly reduce the installation space.
　・The skid mount structure greatly increases the ease of transportation and installation of the unit.
　・The design minimizes heat loss and pressure drop.

2. Low Cost
　・Medium pressure city gas (0.1 MPa or higher) can be used as feedstock, which helps reduce the compression power significantly.
　・The off-gas from PSA is efficiently used as fuel for the burner of the reformer, which reduces the specific energy consumption (the feed gas consumption rate).
　・Standardization of specifications for main equipment contributes to reduced fabrication cost.
　・The skid mount structure contributes to significant reduction in installation time and cost at customers’ sites.

3. Easy Operation
　・The system can be started and stopped with a single button.
　・Simple routine maintenance saves labor.
　・Automatic load-following operation is possible within the range of 40% to 100%. Standard-type HYSERVE has a function that keeps standby operation.
　・Remote monitoring and alert systems ensure quick action against troubles.
