Networks optimization for capturing and transporting CO2

For solving the problem of climate change caused by greenhouse gas, researches and measures of reducing greenhouse gas emissions have been proposed widely around the world. Reducing CO₂-the most prominent greenhouse gas contributing to global warming, is the major project for each country. CCS, the major means to avoid the CO₂ emission from using of fossil fuels, is an effective technology that captures CO₂ and transports it to an sequestration isolating C0₂ from the atmosphere. According to the active CCS projects in progresses, typical CCS pipline transportation network is that transport the captured CO₂ from CO₂ sources to sequestration directly, which has disadvantage in trems of cost effect. Therefore, in our research, we proposed a new CCS pipeline network that by adding CO₂ storage site, generates source-CO₂ storage site-sequestration network using Harmony Search Algorithm to find the optimal solution. A real-life case study in South Korea with 22 emission sources and three sequestrations is provided.
