日本环境省已于9月4日开始接受两项补贴计划的公开申请,旨在加速钙钛矿太阳能电池的早期推广,并推动电池一体化实现储能平价,申请截止日期为10月上旬。
《读卖新闻》本周报道称,该补贴将覆盖购置和安装钙钛矿太阳能组件费用的最高75%,对被用作应急避难场所的设施补助比例更高,但报道并未说明消息来源。
根据环境省介绍,第一项计划为2025财年脱碳与经济转型补贴,重点支持钙钛矿太阳能电池的社会化应用示范,目标场景包括自发自用比例高、靠近用电负荷中心或具备重要应急供电功能的地点。
符合条件的项目须使用薄膜型钙钛矿电池,每个设施发电量不低于5千瓦,并安装在承重不超过每平方米10公斤的场所。地方政府、企业及机构均可申请,截止日期为2025年10月3日。
第二项计划为2025财年民间可再生能源减排补贴,重点通过支持与第一项计划配套的储能设施安装,实现光储一体化平价。申请方需同步部署储能系统,企业及机构可在2025年10月7日中午(日本时间)前提交申请。
日本已设定到2040年实现20吉瓦钙钛矿太阳能装机的目标,相关进展由柔性叠层电池技术与新型制造工艺推动。业内正在试验将轻质组件安装在不适合传统组件的屋顶上,同时政府也在支持固态电池研发。最新研究显示,光储热泵一体化系统在多个地区的经济性正在改善。
