As a rocket propellent of hydrocarbon fuels, the characteristics of liquefied natural gas was evaluated with the viewpoint of the constituents and content, the cooling performance as a coolant, and characteristic velocity and specific impulse as parameters of the engine performance. Content of methane was a principal factor to determine the characteristics as a rocket propellant and more than 90% of it was needed as a fuel and coolant in the regenerative cooled liquid rocket engine. Some constituents of the liquefied natural gas can be frozen by the pre-cooling of the pipe lines, therefore they can be a factor disturbing the normal working of engine. In case the content of methane is around 90% in the liquefied natural gas, a normalized stoichiometric O/F mixture ratio of 0.75 is suggested for a nominal operation condition to get the maximum specific impulse and characteristic velocity.

Innovative technical process for Energy Storage System (ESS), Liquid Air Energy Storage system (LAES) is mature technologies based on the gas liquefaction process. In spite of many advantages such as high energy density, no geographical constraints, low investment costs and long useful life, the system has not yet widely commercialized due to low round trip efficiency. To improve RTE and acquire high yield of liquid air, various configurations of LAES process have been considered. In this research, dual refrigerants cycle (R-600a and methanol) for air liquefaction and thermal oil circulation for power generation via liquid air gasification have been applied to improve cycle performance significantly using Aspen HYSYS simulator.

Currently, the government's announcement of the Korean version of the New Deal Comprehensive Plan ('20.7.14), expanding the supply of hydrogen production and charging facilities, and major companies are rapidly building related facilities such as liquefied hydrogen plants and charging stations. However, safety standards for production, storage facilities, transportation, and utilization of liquefied hydrogen value chains in Korea are insufficient, and safety technologies and safety standards over the entire period of liquefied hydrogen are urgently needed. Accordingly, the Korea Gas Safety Corporation is trying to realize a safe hydrogen economy in Korea by enacting safety standards over the entire period, including liquefied hydrogen plants

This research was carried out to investigate the component isolation method from liquefied waste paper. and isolated component was analyzed by molecular weight distribution with gel chromatography and nitrobenzene-oxidation analysis. In the aspect of liquefaction ratio, wet defibration fiber are better than dry defibration fiber because of wet defiberation fiber was easy to access of chemical solution. The optimal liquefaction condition of waste paper was treated at 190℃ for 60 min(cresol 2 ㎖, water 4 ㎖, phosphoric acid 0.5 ㎖ based on waste paper 1 g). In the liquefied waste paper, lignin and carbohydrate were separated with two interfacial layer(cresol layer, water layer). In the chemical analysis of isolated lignin, molecular weight distribution of isolated lignin was below 1,000.

According to the government's roadmap for revitalizing the hydrogen economy, various industries carry out projects using liquefied hydrogen as an energy source. However, safety standards necessary for operational demonstration projects are not prepared in Korea, thus, it is necessary to prepare safety standards as soon as possible. Therefore, in order to secure the safety of liquefied hydrogen instrumentation and handling facilities, it is necessary to prepare safety standards that comprehensively consider the risk of liquefied hydrogen. This study aims to prioritize safety standard items using ETA, FMEA, and AHP, which are risk assessment techniques, to present the feasibility of selecting safety standard items.
