The U.S. Department of Energy (DOE) is proposing to provide federal funding to the Center for Transportation and the Environment to develop aconformable hydrogen storage pressure vessel.
Proposed project activities include: Test vessel design and fabrication; Kelvar over-braiding; Plastic extrusion and corrugation; Hydrostatic burst testing; Vessel thermodynamic modeling; Hydrogen leakage testing; Hydrogen storage system design, fabrication, and assembly; and storage system demonstration. All proposed activities consist of design, fabrication and bench-scale laboratory work and would take place in existing buildings or laboratories. Design, fabrication and hydrostatic burst testing would occur at the HECR facility in Fort Wayne, IN. All hydrogen-related work would occur at the University of Texas – Center for Electromechanics laboratory in Austin, TX. The initial test vessel with a four liter volume would be burst tested to exceed 2170 bar hydrostatically. Hydrostatic burst testing uses water as the pressurizing agent; therefore, it releases very little energy at the bursting point. The failure mode for the HECR tanks is non-fragmenting so leaks would appear in the form of tiny pin holes. Project hazards are expected to be related to high pressure gas storage and hydrogen gas. For all hydrogen testing, UT-CEM would follow their internal hydrogen safety policy, and conduct all hydrogen testing in the UT-CEM hydrogen test lab, which is approved for indoor hydrogen testing. Under this project the team would examine and develop a hydrogen safety plan updated as needed for this project scope. No modifications to buildings or new permits, additional licenses and/or authorizations are expected to be required as a result of the proposed project.
