T/CAS 590-2022 Natural gas hydrogen blending station technical specification
Basic Information
Scope
This document specifies the technical requirements for the layout of natural gas hydrogen blending stations, their processes and facilities, fire protection and water supply and drainage, electrical systems and automatic control, buildings and heating ventilation, construction and acceptance, operation and maintenance.
This document applies to the design, construction, acceptance, and operation and maintenance of independent natural gas hydrogen blending stations with a total hydrogen storage capacity of no more than 8,000 kg, a hydrogen blending ratio of no more than 20% (by volume), and a hydrogen-blended natural gas pressure of no more than 4 MPa. When natural gas hydrogen blending stations are co-built with urban gas gate stations, storage and distribution stations, gas pressure regulating stations, hydrogenation stations, and hydrogen production stations, this document can be referenced.
