Abstract: A plant and a method for the production of hydrogen and bicarbonate. The plant includes a gasifier, a reformer, a direct contact exchanger and an apparatus for the production of bicarbonate. The plant is suitable for receiving fuel, oxygen, water, carbonate, brine at the inlet and for producing hydrogen, bicarbonate and calcium chloride at the outlet. The plant uses a self-cleaning direct contact heat exchanger to cool the syngas downstream of the reformer and to produce the superheated steam that feeds the gasifier: this heat exchanger allows the production of hydrogen at low costs and in modular plants.

Abstract: The invention relates to a plant for generating negative emissions of CO2. The plant 100 comprises a gasifier 110, a lime kiln 130, a separator 150, and a CO2 permanent storage 170. The gasifier is suitable for receiving as input a fuel 111 and for producing as output a high-temperature syngas flow 114. The lime kiln is suitable for receiving as input carbonate mineral 131 and the high-temperature syngas flow, the lime kiln being further suitable for producing an oxide 134 and for releasing as output a flow of syngas 133 enriched with CO2. The separator is suitable for receiving as input a gas flow containing CO2 and for treating it so as to separately provide at least CO2 151. The CO2 permanent storage is suitable for enclosing along time the CO2. The invention also relates to a method for generating negative emissions of CO2.
