Regasification systems in Floating Storage Units (FSRUs) that use the steam generated by boilers as heat source (closed loop) liquefied natural gas (LNG) regasification process are less detrimental to marine environment than those seawater (open loop). Their drawback, however, lies significant increase fuel consumption and, thus, CO2 emissions. The present paper performs an energy, exergy and e...

In order to lessen reliance on fossil fuels, a rise in interest the utilization of fluctuating and intermittent heat sources derived from renewable energy (such as solar thermal, ocean geothermal) waste has been observed. These could be used generate electricity at relatively low medium temperatures, for example, through organic Rankine cycle (ORC). some case studies, various approaches have de...
