Heat Integration of Liquid Hydrogen-Fueled Hybrid Electric Ship Propulsion System

Journal of Marine Science and Engineering, 2023
This study introduced the methodology for integrating ethylene glycol/water mixture (GW) systems which supply heat energy to the liquid hydrogen (LH2) fuel gas supply system (FGSS), and manage the temperature conditions of the battery system. All systems were designed and simulated based on the power demand of a 2 MW class platform supply vessel ...
