Model for utilizing natural gas associated with hydrogen in pre-salt off-shore explorations
| Resumo: | This article presents the study of a new concept for H2 production based on SMR technology from associated natural gas in offshore production in the Brazilian Pre-Salt region. It highlights the potential of using this gas, combined with CCUS devices, to explore crude oil and control fugitive emissions. Based on the evolution of historical series data of flaring and losses of natural gas in offshore production units, it is concluded, through the statistical regression method, that flaring and losses of natural gas are predicted to be below 3.0% of natural gas production with rates estimated above 1.5% in 2050 and reaching around 1% of production by the end of this century. By 2050, for a scenario involving the implementation and deployment of multiple H2 processing systems in offshore production units, it is estimated that approximately 41.8% of ordinary flaring will be reduced, and approximately 956 MMm3 of H2 will be produced. Doubts and uncertainties persist about achieving carbon neutrality by 2050 and zero routine flaring in offshore production by 2030 to meet the targets set in public policy agendas. |
