Testing Facility for Hydrogen Storage Materials Designed to Stimulate Application based Conditions

1. Testing Facility for Hydrogen Storage Materials Designed to Stimulate Application based Conditions A perspective presentation by National Centre for Catalysis Research Indian Institute of Technology, Madras

2. Why This Presentation Now? • Intrinsic storage property is important • Also Important is the performance under Practical conditions • Urgent Need to test storage materials under conditions under day to day use • In this presentation one of the possible models is presented for discussion

3. Why This Presentation –II? • By 2050, the energy needs will double the present level • Sustainable hydrogen based economy appears to be a viable alternative • The key component of this change over is the storage • Zero emission possibility • Large challenges for transforming the laboratory scale to actual applications

4. DOE revised by 205 5.5 weight percent • ~3.3 min for 5 kg H2 • Heat management - 35 kcal/mol H2 total release of 450kW • Heat, kinetics and thermodynamics • Heat and mass transfer characteristics • Models are empirical and dimensionality of heat transfer (conduction, convection and Radiation)

5. What is Challenging? • This reactor setup has to be unique as it has to • enable to test the influence of the heat and mass flow, temperature effects, flow or “dead-end” reactor loading, bed stability, storage capacity, filling times, grain size, and contamination effects, simultaneously.

6. Creation of Test Facility for Hydrogen Storage The NIST Hydrogen Test Facility is described atwww.nist.gov/mml/materials_reliability/structural_materials/hydrogen-pipeline-safety.cfm.

7. TWI is building a unique test facility to allow a comprehensive range of mechanical tests to be performed in hydrogen gas at 1000bar pressure. Whilst TWI's current facility is capable of simple tensile and axial fatigue tests at450bar and 20 - 100°C, the new facility is capable of performing more sophisticated tests, including fracture toughness and fatigue crack growth rate tests from -150 to +150°C, in addition to withstanding the increased pressure. • Once commissioning is complete, TWI will be undertaking testing as part of a project involving major automotive manufacturers in their search for the optimum material selection for fuel tanks and other components on hydrogen powered cars. • Working with TWI, manufacturers will have the opportunity to carry out research and development work in a facility that is unique within Europe. • For more information about the facility and TWI's work in this field, contactmcs@twi.co.uk
