Claims
1. A hydrogen storage device comprising a heater/cooler module and a pressure containment vessel defining an interior volume and having within it:
a thermally conducting network having a face in thermal contact with the
heater /cooler module, the shape of the thermally conducting network being a
fractal geometry in two or three dimensions; and
a hydrogen storage material in thermal contact with the thermally conducting
network.
2. A hydrogen storage device as claimed in claim 1 in which the heater/cooler module is a thermoelectric heater and cooler.
3. A hydrogen storage device as claimed in claim 2 in which the thermoelectric heater and cooler is a Peltier device.
4. A hydrogen storage device as claimed in any one of claims 1 to 3 in which the thermally conducting network is made of aluminium, copper or stainless steel.
5. A hydrogen storage device as claimed in any one of claims 1 to 4 in which the pressure containment vessel defining the interior volume has within it a metal foam in thermal contact with the thermally conducting network.
6. A hydrogen storage device as claimed in claim 5 in which the metal foam is a foam of aluminium, copper, stainless steel, nickel or zinc.
/. A hydrogen storage device as claimed in any one of claims 1 to 6 in which the hydrogen storage material is a metal hydride.
8. A hydrogen storage device as claimed in claim 7 in which the metal hydride is selected from MgHz2, NaAlHs4, LiAlH4, LiH, LaNisHs, TiFeHz, palladium hydride, LiNH2, LiBH4 and NaBH4
9. A hydrogen storage device as claimed in any one of claims 1 to 8 in which the fractal geometry is selected from a Quadratic Koch Island, a Quadratic Koch surface, a Von Koch surface, a Koch Snowflake, a Sierpinski carpet, a Sierpinski tetrahedron, a Mandelbox, a Mandelbulb, a Dodecahedron fractal, a Icosahedron fractal, a Octahedron fractal, a Menger sponge, a Jerusalem cube, and a 3D H-fractal.
10. A hydrogen storage device as claimed in any one of claims 1 to 9 in which the heater/cooler module includes a heat sink.
11. A hydrogen storage device as claimed in any one of claims 1 to 10 which further contains hydrogen.
12. A method of storing hydrogen which comprises a step of passing hydrogen gas into a device as claimed in any one of claims 1 to 10.
13. A method as claimed in claim 12 in which further comprises applying cooling to the device during the hydrogen addition step.
14. A method of providing hydrogen which comprises a step of releasing hydrogen gas from a device as claimed in any one of claims 1 to 10.
15. A method as claimed in claim 14 in which further comprises applying heating to the device during the hydrogen release step.
