Numerical Study on Optics and Heat Transfer of Solar Reactor for Methane Thermal Decomposition
Oct 2021
Publication
This study aims to reduce greenhouse gas emissions to the atmosphere and effectively utilize wasted resources by converting methane the main component of biogas into hydrogen. Therefore a reactor was developed to decompose methane into carbon and hydrogen using solar thermal sources instead of traditional energy sources such as coal and petroleum. The optical distributions were analyzed using TracePro a Monte Carlo ray-tracing-based pr Read More
Hydrogen Economy Roadmap of Korea
Jan 2019
Publication
Hydrogen economy" refers to an economy where hydrogen is an important environmentally-friendly energy source brings out radical changes to the national economy and society as a whole and is a driving force behind economic growth.As hydrogen is not only a driver of innovative growth but also a means of using energy in a more eco-friendly way a hydrogen economy refers to the pursuit of a society that realizes the unlimited potential of hydrogen.T Read More
Modeling and Economic Operation of Energy Hub Considering Energy Market Price and Demand
Feb 2022
Publication
This paper discusses the economic operation strategy of the energy hub which is being established in South Korea. The energy hub has five energy conversion devices: a turbo expander generator a normal fuel cell a fuel cell with a hydrogen outlet a small-scale combined heat and power device and a photovoltaic device. We are developing the most economically beneficial operation strategy for the operators who own the hub without making an Read More
A Study on the Prediction of the Temperature and Mass of Hydrogen Gas inside a Tank during Fast Filling Process
Dec 2020
Publication
The hydrogen compression cycle system recycles hydrogen compressed by a compressor at high pressure and stores it in a high-pressure container. Thermal stress is generated due to increase in the pressure and temperature of hydrogen in the hydrogen storage tank during the fast filing process. For the sake of safety it is of great practical significance to predict and control the temperature change in the tank. The hydrogen charging process in the Read More
Life Cycle Assessment of Greenhouse Gas Emissions in Hydrogen Production via Water Electrolysis in South Korea
Dec 2024
Publication
This study evaluated the greenhouse gas (GHG) emissions associated with hydrogen production in South Korea (hereafter referred to as Korea) using water electrolysis. Korea aims to advance hydrogen as a clean fuel for transportation and power generation. To support this goal we employed a life cycle assessment (LCA) approach to evaluate the emissions across the hydrogen supply chain in a well-to-pump framework using the Korean clean hydr Read More
