Analysis of wind to hydrogen production and carbon capture utilisation and storage systems for novel production of chemical energy carriers

As the offshore energy landscape transitions to renewable useful decommissioned or abandoned oil and gas infrastructure can be repurposed in context of circular economy. Oil platforms, for example, offer opportunity hydrogen (H2) production by desalination electrolysis sea water using wind power. However, as H2 storage transport may prove challenging this study proposes react with carbon dioxide (CO2) stored depleted reservoirs. Thus, producing a more transportable carriers like methane methanol reservoir. This paper presents novel thermodynamic analysis Goldeneye reservoir North Sea Aspen Plus. For Goldeneye, which store 30 Mt CO2 at full capacity, if connected 4.45 GW farm, it has potential produce 2.10 annually abate 4.51 from grid.
