1. A plant for the production of H2 and bicarbonate comprising: a gasifier, a reformer, an apparatus for the exchange of heat in which the syngas is cooled and in which superheated steam is produced, an apparatus for the capture of CO2 and for the production of bicarbonate, wherein:
the gasifier is configured to receive a fuel at its input, receive a steam flow, and an oxygen flow, and produce a high temperature syngas flow at its output and an ash flow;
the reformer is configured to receive the high temperature syngas flow produced by the gasifier, the oxygen flow, configured for a catalytic or thermal reformation of the hydrocarbons present in the syngas and is configured to release a high temperature syngas flow;
the apparatus for heat exchange comprising a first direct contact heat exchanger and a second direct contact heat exchanger;
the first direct contact heat exchanger is configured to receive the high temperature syngas flow produced by the reformer, the low temperature heat carrier flow and release a syngas flow at lower temperature and a heat carrier flow at high temperature;
the second direct contact heat exchanger is configured to receive the water flow and the high temperature heat carrier flow and release the superheated steam and the heat carrier flow at low temperature;
the apparatus for CO2 capture and bicarbonate production includes a mixer and an ion exchange apparatus, an osmosis concentrator for the concentration of the bicarbonate rich solution, and a dryer;
the mixer is configured to receive the low temperature syngas flow, the H2O flow, the carbonate flow and to release a mixture and a flow of hydrogen;
the ion exchange apparatus is configured to receive the mixture, a flow of brine at the input and release a flow of CaCl2) and a solution of water and bicarbonate;
the osmosis concentrator is configured to receive the water and bicarbonate solution at the input and to release the water flow and the concentrated bicarbonate solution; and
the dryer is configured to receive the concentrated bicarbonate solution at the input and to release at least the solid bicarbonate flow.
