A system for the material use of hydrogen includes a transfer-hydrogenation facility with a transfer-hydrogenation unit for the hydrogenation of a material for hydrogenation and a hydrogen-provision device for the provision of hydrogen for the transfer-hydrogenation facility, where, via the hydrogen-provision device, hydrogen in bound form is provided for the transfer-hydrogenation facility, and the hydrogen-provision device includes a loading unit for the loading of a carrier medium with hydrogen.

Techniques, systems and material are disclosed for thermochemical regeneration of biomass into renewable engineered fuel, storage of the renewable engineered fuel, respeciation of the renewable engineered fuel and transport. In one aspect, a method includes generating low density hydrogen fuel from biomass dissociation at a first location of a low elevation. The low density hydrogen fuel is self-transported in a pipeline to a second location at a higher elevation than the first location by traveling from the first location to the second location without adding energy of pressure. A high density hydrogen carrier is generated at the second location of higher elevation by reacting the low density hydrogen fuel with at least one of a carbon donor, a nitrogen donor and an oxygen donor harvested from industrial waste. The high density hydrogen carrier is delivered to a third location of a lower elevation than the second location while providing pressure or kinetic energy.

The present invention relates to a process for producing and for regenerating siloxane hydrogen carrier compounds.

Processes for controlling liquid organic hydrogen carrier processes are described. The processes include flow control of hydrogen as the primary variable with toluene make-up based on reactor conditions. Make-up hydrogen gas is provided via a flow controller which can be adjusted by the operator. A pressure controller on the separator is used to adjust the temperature at the reactors with a temperature controller. The inlet temperature to the reactors is maintained by heat exchangers, such as steam generators. The reaction conditions are monitored by temperature measurement and the inlet and/or the outlet of the reactor. When hydrogen feed rates are adjusted, the unit operations must increase or reduce the toluene to balance this situation. A differential temperature controller is used to reset the toluene flowrate to the reactor to achieve the desired processing objective.

The present invention provides a system, a process and a method of storing hydrogen (H.sub.2) and releasing it on demand, comprising and making use of N-heterocycles as liquid organic hydrogen carriers (LOHCs).

Mixed metal metal-organic frameworks (MM-MOFs) of copper-1,3,5-benzenetricarboxylate (BTC), M-Cu-BTC, wherein M is Zn(II), Ni(II), Co(II), and/or Fe(II) may be made using post-synthetic exchange (PSE) with metal ions. Such MM-MOFs may be used in H.sub.2 storage, especially Ni(II) and Co(II) MM-MOFs. Selected metal exchanged materials can provide gravimetric H.sub.2 uptake around 1.63 wt. % for ZnCu-BTC, around 1.61 wt. % for NiCu-BTC, around 1.63 wt. % for FeCu-BTC, and around 1.12 wt. % for CoCu-BTC.

A method of transporting hydrogen may comprise providing hydrogen gas comprising a first hydrogen gas portion produced by a method with no direct carbon emissions to the atmosphere and a second hydrogen gas portion produced by a method with direct carbon emissions to the atmosphere; at a first hydrocarbon processing facility, hydrogenating a hydrocarbon feed in the presence of the hydrogen gas to form a hydrogenated effluent; transporting a portion of the hydrogenated effluent from the first hydrocarbon processing facility to a second hydrocarbon processing facility; and at the second hydrocarbon processing facility, dehydrogenating the portion of the hydrogenated effluent to form a hydrogen gas product. On average, a mass flow rate of the first hydrogen gas portion may be at least 90% of a mass flow rate of the hydrogen gas product. The first hydrocarbon processing facility and the second hydrocarbon processing facility may be separated by a distance of at least 100 km.
