(566i) A Systematic Approach in Developing Alkaline Electrolysis Based Power to Gas Infrastructures Business Models
Power to gas technology is drawing an increasing attention as an only realistic solution for this because it can take advantage of redundant electricity energy into other energy sources that can be stored and used again later. Other energy storage options such as energy storage system is not desirable at the most because of high capital investment and deteriorating efficiencies. At the moment, Alkaline electrolysis is one of most established technologies that generate hydrogen from redundant renewable energy. Most attention has been given to develop specific manufacturing technologies and the corresponding high performing material. Active works on experiments in laboratory and pilot scale plant has been reported in the literature. There is much to be done for commercially competitive power to gas industry.
This work is concerned with identifying potential issues in constructing alkaline electrolysis based power to gas infrastructure in commercial scale. Particularly it focused on establishing the value chain aspects to put the actual power to gas infrastructure into action. After cutting edge global R&D status are analyzed. the impact of internal and external factors for the operation of the alkaline electrolysis power to gas value chains are evaluated. Issues are addressed for developing a decision-making framework for the operation of alkaline electrolysis supply chains under the presence of various factors. A recent South Korea case is presented to illustrate the applicability of the decision-making framework with some remarks.
