GRID BASED RISK ASSESSMENT OF A HYDROGEN SUPPLY CHAIN

Today's energy recourses are not supposed to be sufficient to fulfill increased energy demand in the near future, thus researchers and governments look forwards to alternative energy sources. Hydrogen energy is one of these alternative energies. To increase the use of hydrogen energy, it is essential to establish a good hydrogen supply chain (HSC), which provides the transmission of hydrogen from production facilities to the users. There are several key issues which must be addressed in establishing a good HSC like capital cost and operating costs, environmental effects like CO2 emission, and risks. Although minimizing the total costs or total CO2 emissions can be appropriate for a country, minimizing the cumulative risk may result in an unbalanced risk load between cities or grids of a country. In this study we analyze establishing the HSC of Turkey and showed that minimization of total risk yields low risks in grids with low population and grids with higher populations have to cope with larger risks.
