The present disclosure refers in one embodiment to processes for making and transporting clean hydrogen fuel. The processes may involve hydrotreating, hydrocracking, or both hydrotreating and hydrocracking an aromatic feedstock under conditions to obtain a liquid hydrocarbon fuel. The liquid hydrocarbon fuel is hydrogenated to obtain a hydrogen-rich fuel that is transported to a dehydrogenation facility that may also be at or near a hydrogen station. The hydrogen-rich fuel is used to obtain hydrogen and a second liquid hydrocarbon fuel.

The invention has this special feature that the at least one first plate-shaped element includes at least one arrangement of a first section and of a second section spaced apart from the first section in a direction transverse to a plane substantially defined by the first plate-shaped element, and the first section of the first plate-shaped element is joined with sealing to the at least one second plate-shaped element so that a first section of the reaction chamber is formed between the second section of the first plate-shaped element and the second plate-shaped element.

The present invention proposes a thermochemical battery cycle, termed a Benzene Battery cycle, for efficiently storing electric and/or thermal energy for later and/or distant use. The methods and apparatus herein proposed utilize reversible endothermic fluid and exothermic fluid thermochemical means for efficiently storing H2 in a liquid state at STP. The present invention is generally based on the technology disclosed in U.S. Pat. Nos. 3,225,538, 3,067,594, and 3,871,179, wherein techniques are described for creating a unique thermochemical cycle, termed the Bland/Ewing Cycle (B/E Cycle) after the co-inventors, involving “molecular expansion” and “molecular compression”. The present invention is also based on US Patent Application #18-0954634 which proposes optimizing endothermic and exothermic “segments” for the creation of either Combined Heat and Power (CHP) or Combined Cycle (CC) applications.
