  • Study on economics of the Hakodate hydrogen supply chain using offshore wind power in southern Hokkaido

抄録

<p>In order to achieve carbon neutrality by 2050, it will be necessary to introduce renewable energy for electricity and heat supply. Therefore, this study examines the possibility of supplying energy to Hakodate City from a 722 MW rated offshore wind power generation system planned off the coast of Hiyama in southern Hokkaido. In the proposed system, power from the offshore and onshore wind turbines will be transmitted to a substation near Hakodate City via a transmission line. Substations A, B, and C have different storage methods: substation A uses hydrogen and storage batteries; substation B uses only hydrogen; and substation C uses only storage batteries. These stored hydrogen and electricity will be transmitted to Hakodate City in the event of supply shortages. The analysis results show that the introduction cost is approximately 830 billion yen lower when electricity stored in storage batteries is used preferentially, compared to the case where hydrogen is used preferentially. Therefore, we believe that using electricity stored in storage batteries as a priority, reducing the storage battery capacity and increasing the hydrogen tank capacity, will result in a system with lower installation costs and a higher supply ratio.</p>
