In 2010, a multi-partner, multi-year research program called Low Cost, Durable Thermoplastic Hydrogen Storage Tanks, or DuraStor, was formed to address these problems by investigating a drop-in replacement for Type IV tanks. A UK-only program called Hydrogen – Optimisation of Storage and Transfer (HOST) picked up where DuraStor left off in mid-2014. These were the participants.
DuraStor program members and responsibilities (2010-2014):
· EPL Composite Solutions (Loughborough, U.K.) — project lead, consolidation of vessel structures.
· Delta Motorsport Ltd. (Northants, U.K.) — market research and development of case-study design.
· Oxford Brookes University (Oxford, U.K.) — stress analysis, life-cycle analysis, recycling opportunities.
· Element Materials Technology Hitchin Ltd. (Hitchin, U.K.) — testing of target materials and prototype vessels, identifying suitable organizations to conduct dangerous tests outside its own expertise (e.g., fire and penetration testing); high-pressure permeation testing using hydrogen for the rotomolded liner samples, mechanical tests (quasi-static and fatigue) on all materials; accelerated aging tests and rapid gas decompression (RGD) tests to assess the effects of rapid depressurization on the liner materials.
· Celanese Corp. (Dallas, Texas) — development and supply of vessel materials.
· Crompton Mouldings Ltd. (West Yorkshire, U.K.) — rotomolding tooling and rotomolded cylinder liners.
· CTG Ltd. (Banbury, U.K.) — filament winding of vessel overwrap.
2014-2017 HOST program members:
· EPL Composite Solutions — see above.
· Element Materials Technology Hitchin Ltd. — see above.
· Crompton Mouldings Ltd. — see above.
· Jonam Composites Ltd. (Mansfield, U.K.) — supplier of composite tape.
· JRE Precision Ltd. (Leicestershire, U.K.) — supplier of tank hardware.
High-pressure gas storage vessels represent one of the biggest and fastest-growing markets for advanced composites, as transportation markets demand alternative fuels (CNG and hydrogen) for motive power systems.
Design group's new winding option streamlines new pressure vessel development.
Cimarron Composites has made a leap forward in all-composite cryogenic tank development.
