Outline of Final Research Achievements

The energy cost reduction in a fishery village with a hybrid energy system incorporating hydrogen and renewable energy sources was calculated under the assumption that hydrogen power could be sold. The calculation did not identify a suitable configuration and operation of the facilities to achieve cost reduction. However, if the demand for hydrogen energy increases in the future, the fishery village could potentially obtain greater benefits than under the current situation. Additionally, a miniature model mimicking the proposed hybrid energy system was designed, and a control algorithm for it was verified through computer simulation.

Academic Significance and Societal Importance of the Research Achievements

漁村は我が国にとって重要な位置にあり，これを存続するために漁村内のエネルギーシステムの改良にとどまらず，漁村にエネルギー生成基地としての役割を持たせることについて数値試算を行った。現状に即した数値試算では，当初に期待したような効果は発生しないことがわかったが，将来的には水素エネルギーの需要は増えることが見込まれる。そのような状況においては，提案したエネルギーシステムはさらなるメリットをもたらすことが期待でき，このことは漁村が持続可能となることにつながる。
