This paper describes a feasibility study about the storage of hydrogen in the form of clathrate hydrates. The specific objective of this paper is to present a conceptual design of a hydrogen-hydrate production plant applicable to a large-scale in-situ storage of hydrogen produced in an industrial complex area. The plant was so designed as to produce a simple hydrogen hydrates under the pressure of 35 MPa and temperature of 140 K. The rate of hydrogen uptake into the hydrates during their production in each plant was targeted for 3,000 Nm^3/h. We have prepared a process flow diagram accompanied by material-balance and machinery specifications. The energy consumption in plant operation has also been evaluated, assuming that the cool energy generated by adjacent LNG facilities may or may not be available for cooling the hydrate-forming assemblies in each plant.
