A process for producing and storing hydrogen in liquid and/or gaseous form and for producing ammonia in a step A) and, in a step B), for producing electricity and for producing and storing liquid and/or cryo-compressed nitrogen and ammonia, wherein said step A) comprises using the liquid and/or cryo-compressed nitrogen produced and stored in step B) from a combusted gas flow and wherein step B) comprises using the use-of hydrogen in liquid and/or gaseous form produced and stored in step A).
A plant comprising a liquid and/or cryo-compressed nitrogen tank, a liquid hydrogen tank, a gaseous hydrogen tank, an ammonia synthesis unit for the synthesis of ammonia with a working fluid circuit, an air compressor, a combustor for subjecting an air flow to combustion a gas turbine with a generator or an expander for generating electricity and possibly a further turbine in the working fluid circuit of the ammonia synthesis unit connected to a generator for further generating electricity, and heat exchangers for heat exchange between a liquid nitrogen flow withdrawn from said liquid and/or cryo-compressed nitrogen tank and intended for said ammonia synthesis unit and a liquid and gaseous and/or cryo-compressed hydrogen flow intended for said liquid hydrogen tank and said gaseous hydrogen tank and obtained from water electrolysis, or for heat exchange between a nitrogen flow intended for said liquid and/or cryo-compressed nitrogen tank and obtained from a combusted gas flow and a liquid and/or gaseous hydrogen flow withdrawn from said liquid hydrogen tank or gaseous hydrogen tank.
