(57) 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.
