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
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
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
• 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)
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.
Creation of Test Facility for
Hydrogen Storage
The NIST Hydrogen Test Facility is described
atwww.nist.gov/mml/materials_reliability/structu
ral_materials/hydrogen-pipeline-safety.cfm.
• 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.
