Abstract
A method is described for generating carbon-neutral electricity using purified hydrogen as an energy source. A recyclable LOHC is provided to the process for reversible dehydrogenation. Hydrogen generated by dehydrogenation is purified and electrochemically converted to electricity. Heat for maintaining the dehydrogenation reaction temperature is derived from combustion of a portion of the liquid products from dehydrogenation, the portion combusted being less than or equal to the portion of carbon-neutral component included in the recyclable LOHC.
Claims11
A process for supplementing the generation of electricity from one or more renewable resources, comprising the steps of:
- a. preparing a hydrogen enriched liquid organic hydrogen carrier (R-LOHC) by means of a hydrogenation reaction using a first hydrogen depleted liquid organic hydrogen carrier (S-LOHC) and a first source of gaseous hydrogen within a hydrogenation reaction zone;
- wherein said first source of gaseous hydrogen is produced by electrolysis of an aqueous fluid using an electrolysis cell powered by a first source of electricity;
- wherein said first source of electricity is sourced from at least one renewable resource;
- wherein said R-LOHC is optionally stored within an R-LOHC storage vessel;
- b. generating a second supply of electricity by means of an electrochemical conversion of a second source of gaseous hydrogen within a fuel cell;
- wherein said second source of said gaseous hydrogen is produced by means of a second dehydrogenation reaction using said R-LOHC in a dehydrogenation reaction zone;
- c. obtaining a second S-LOHC comprising unloaded aromatic substrate from said dehydrogenation reaction zone after said second dehydrogenation reaction;
- wherein said first S-LOHC is optionally stored within a first S-LOHC storage vessel;
- and wherein said second S-LOHC is optionally stored within either said first S-LOHC storage vessel or a second S-LOHC storage vessel;
- and
- d. combusting a portion of the S-LOHC unloaded aromatic substrate in a combustor and supplying at least a portion of the heat generated by said combustor for maintaining the dehydrogenation reaction zone temperature within said dehydrogenation reaction zone.
