Abstract
Massive variable renewable integration will serve as an important measure to address energy and environmental issues, while its extensive installation would place a technical challenge in power grid management for controlling its intermittency. Among various treatment measures for the variable renewables, hydrogen storage system is one of technical candidates besides rechargeable battery, suppression control and back-up generator. For practically positioning it in power system, the development of an energy model is a key procedure to quantify and qualitatively understand the potential benefits of hydrogen storage system for variable renewables. The authors assess the potential for hydrogen storage of variable renewables in Hokkaido region of Japan with abundant wind resources by employing a high time-resolution optimal power generation mix model. The main feature of the developed model is that considered time-resolution is 10-min through a year, allowing us to investigate the impact of various short-cycle renewable variation on the deployment of hydrogen storage system in a detailed manner. Simulation results potentially suggest that CO2 regulation encourages the installation of hydrogen storage for variable renewable if its cost reduction is fully realized, and the results reveal as well that hydrogen is suitable energy carrier for long-term storage of wind power output.
