Challenges in the Use of Alternative Fuels: Solutions to handle Boil-Off Gas in Agricultural Machines

open access: yes, 2022
To meet the climate targets, it is necessary to reduce greenhouse gas emissions from all areas. Liquefied Natural Gas (LNG), which consists largely of methane, can be produced sustainably and it is suitable for mobile machines due to its high

Energy, Exergy, and Economic (3E) Analysis of Boil-Off Gas Re-Liquefaction Systems Using LNG Cold Energy for LNG-Fueled Ships

open access: yesJournal of Marine Science and Engineering, 2023
Liquefied natural gas (LNG)-fueled ships have the effect of reducing most pollutants, which is advantageous for responding to strict regulations. Because boil-off gas (BOG) is generated in the LNG storage tank of an LNG-fueled ship, a BOG re-liquefaction

Optimal Shape and Boil-Off Gas Generation of Fuel Tank for LNG Fueled Tugboat

open access: yes한국해양공학회지, 2020
This paper proposes the optimal shape of an LNG fuel tank with a lattice pressure vessel (LPV) design for a tugboat. The LPV is a Type C tank with a design philosophy of “design by analysis,” which facilitates greater variability of shape compared with ...
