By combining solar and wind power with the hybrid energy storage system—utilizing batteries for short-term fluctuations and hydrogen storage for long-term balancing—the system can efficiently respond to variable energy demand while minimizing the overall costs of energy supply. Multi-supply systems, which deliver both electricity and hydrogen, also show cost-saving potential. Technological advancements in solar and wind power are more effective for cost reduction than storage improvements. However, current supply costs from the 100% VRE system exceed Japan’s 2030 targets, indicating the need for additional measures to achieve cost competitiveness.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003ePDFファイルサイズ：\u003c\/strong\u003e663Kバイト\u003c\/p\u003e","brand":"IEEJ-PDF","offers":[{"title":"PDFダウンロード（一般価格440円\/会員価格220円） \/ A4 \/ 6","offer_id":47681915027695,"sku":"IEEJ-BTB2025022-PDF","price":440.0,"currency_code":"JPY","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0718\/9512\/2159\/files\/IEEJ-PDF_bumontaikai_59ac9849-23d8-487b-beda-1f73f83fd5cd.png?v=1770872454","url":"https:\/\/ieej.bookpark.ne.jp\/products\/ieej-btb2025022","provider":"電気学会 電子図書館","version":"1.0","type":"link"}
