Today the world energy market is in great transition and the demand of clean energy such as liquefied natural gas (LNG). Increase of natural gas production and supply causes drawback of onshore infrastructure and many environmental restrictions. As solution, offshore large-scale terminals especially Floating Storage and Regasification Unit (FSRU) type is becoming commercially competitive and effective alternative for the areas where onshore gas supply infrastructure is not feasible. LNG production consumes around 850 kJ/kg of LNG energy and it is just dumped into seawater or in the atmosphere despite reusing as extra energy source. In this paper, we review the cold energy economy as well as current status of LNG cold energy utilization technologies. Moreover, current and emerging cybersecurity trends after LNG cold energy implementation at FSRU are proposed and discussed to broaden the perspectives of the researchers in the community and industry experts. Finally, the review concluded with a practical recommendation of implementation of LNG Cold Energy Hub concept for future energy systems.
