HYPER lab: Advancing H2-TRLs

• Only cryo-H2 university lab in US

• Risk, expense, and development timeline are challenging.

• Goal is to progress hydrogen technology from TRL 1-6 as efficiently as possible.

• Necessitates a lean-production philosophy with a continuous design-build-test progression.

Significance of ortho-para manipulation

6

“Because of the entropy difference between ortho- and parahydrogen, it is tempting to think of some external force which could change the equilibrium concentration at some

temperature. Practical levels of electric field gradients or magnetic fields would have only a minor effect on the equilibrium concentration, though further studies may be useful.” ~ Ray

Radebaugh 1982

“Partial ortho-para conversion.. Offers the greatest opportunity for reduced liquefaction power consumption.” ~C. Baker 1979

• 80-90% of non-pipeline H2 delivered via liquid tanker truck.1

• LH2 will propel the early H2 economy.2

• Only 8 LH2 plants in North America-Only 1 is carbon free (Niagara)

-Smallest is 30 tonne/day (>50 MW)

-Can only ramp 30%/day

• Production cost: $5-5.60/kgLH2

• Delivery cost: $4-12/kgLH2

Efficient, small (<1 MW), modular H2 liquefiers will increase

renewable value and enable H2 economy.

Applications: Kinetic para-ortho manipulation via vortex tube

• Vortex tubes separate faster (higher T) from slower due to flow geometry

• Enables para-ortho conversion to drive bulk cooling

B.As hydrogen flows along tube, faster molecules migrate

to outside

C. Catalyst along tube wall causes endothermic conversion of hot

parahydrogen to orthohydrogen

F.Cold H2 outlet

D.Insulation on tube wall

2. Adding Value: By the numbers

Cost of Conventional:

Electricity = $0.07265/kW-hr Natural Gas = $0.05/kW-hr

Cost of H2:

LH2 = $5-18/kg Production = $5/kg Delivery = $2-4/mile Dispensing = $2/kg

3.3 kW-hr = Energy in 1 kg H2 = Energy in 1 gal gasoline

H2 = $1.2-4.10/kW-hr

LH2 is worth 20-40 times more as an energy product.
