Building of infrastructure for the hydrogen society by using a type-4 (resin liner) 106 MPa compound vessel accumulator

Technical Classification:: [ Molding ]
Products:: [ Products / Processed Products ]
Keyword:: [ 106 MPa accumulator for hydrogen stations ] [ 45 MPa compound vessel for transport ] [ 70 MPa tank for FCV ]

Point of the Proposed Technology

・Drastic weight-saving is achieved by adopting a CFRP compound vessel instead of the conventional steel vessel containing chromium-molybdenum steel.　　
・Substantial increase in reliability and safety with use of type-4 (resin liner) --- long-term use for 15 years can be achieved.
・Proposal for building an ultra-compact simplified hydrogen station and a transportation system by using Maruhachi’s compound vessel.
・Bold deregulation and legislation are needed.

Effect(s)

Type-4 (made of resin liner) CFRP compound vessel accumulator with a design withstand pressure 107 MPa, minimum burst pressure 250 MPa, and normal temperature pressure cycles 100,000 cycles of more
