Abstract

A process that includes pre-cooling a H 2 gas feedstock with a compressed liquid natural gas via a heat exchanger, introducing the pre-cooled H 2 gas feedstock into an active magnetic regenerative refrigerator H 2 liquefier module, and delivering liquid H 2 from the active magnetic regenerative refrigerator H 2 liquefier module to a liquid H 2 vehicle dispenser.

First claim

What is claimed is:

1. A process comprising:
pre-cooling a H 2 gas feedstock via a heat exchanger wherein a compressed liquid natural gas is used in the heat exchanger for pre-cooling the H 2 gas feedstock;
introducing the pre-cooled H 2 gas feedstock into an active magnetic regenerative refrigerator H 2 liquefier that comprises at least one layer of a magnetic refrigerant material; and
delivering a first portion of liquid H 2 from the active magnetic regenerative refrigerator H 2 liquefier to a liquid H 2 dispenser for dispensing the liquid H 2 to a liquid H 2 vehicle, and compressing a second portion of liquid H 2 from the active magnetic regenerative refrigerator H 2 liquefier resulting in compressed hydrogen.

2. The process of claim 1 , further comprising compressing liquid natural gas resulting in the compressed liquid natural gas.

3. The process of claim 1 , further comprising:
introducing a portion of the liquid natural gas to a liquid natural gas dispenser for dispensing to a liquid natural gas vehicle;
introducing a portion of the compressed liquid natural gas to a compressed liquid natural gas dispenser for dispensing to a compressed liquid natural gas vehicle; and
introducing the compressed hydrogen into a compressed hydrogen dispenser for dispensing to a compressed hydrogen vehicle.

4. The process of claim 3 , further comprising:
dispensing compressed hydrogen at 700 bar from the compress hydrogen dispenser;
dispensing liquid H 2 at 2.7 bar from the liquid H 2 dispenser;
dispensing liquid natural gas at 2.7 bar from the liquid natural gas dispenser; and
dispensing compressed liquid natural gas at 240 bar from the compressed liquid natural gas dispenser.

5. The process of claim 3 , further comprising generating the H 2 gas feedstock via a solid oxide fuel cell, and introducing methane from the compressed liquid natural gas into the solid oxide fuel cell.

6. The process of claim 1 , wherein the pre-cooling of the H 2 gas feedstock comprises cooling 300 psia H 2 gas from 290 K to 140 K.

7. The process of claim 6 , further comprising introducing the 140 K pre-cooled H 2 gas feedstock into the active magnetic regenerative refrigerator H 2 liquefier, and cooling the H 2 from 140 K to 20 K in the active magnetic regenerative refrigerator H 2 liquefier resulting in the liquid H 2 .

8. The process of claim 7 , further comprising generating the H 2 gas feedstock via a solid oxide fuel cell, and introducing methane from the compressed liquid natural gas into the solid oxide fuel cell.

9. The process of claim 1 , further comprising generating the H 2 gas feedstock via a solid oxide fuel cell.

10. The process of claim 9 , further comprising introducing methane from the compressed liquid natural gas into the solid oxide fuel cell.

11. The process of claim 1 , wherein the active magnetic regenerative refrigerator H 2 liquefier comprises a rotary wheel that includes an annular bed, the annular bed comprising the at least one layer of the magnetic refrigerant material.
