□ 本报记者 张宣 杨易臻 数千万年前形成的盐矿，经过开采后在地下形成一个个盐穴。如今，随着新型储能技术的发展，这些原 本闲置的地下盐穴，正在化身为储存能源的巨型"仓库"。 近日，由中盐集团与清华大学等单位合作的"大规模盐穴储氢"主体工程在常州正式开工建设。这标志着 我国在基于盐穴的大规模储氢领域迈出了关键一步。 为什么用盐穴来储氢？为何选择落地常州？带着这些疑问，《科技周刊》记者采访到该项工程的氢能和 储能专家。 盐穴：地质演化馈赠的天然储库 "大规模盐穴储氢"项目属于国家重点研发计划，由中盐集团和清华大学合作，联合中国地质大学（北 京）、中国科学院理化技术研究所、天津大学、中国矿业大学等多家单位共同开展。该项目将形成具有 自主知识产权的盐穴储氢全套技术体系，以推动盐穴储氢的规模化产业应用。 记者注意到，储氢的载体是盐穴。那什么是盐穴？"所谓盐穴，是指利用水溶开采方式在地下较厚的盐 层或盐丘中形成的人造地下洞穴。这些人工构建的空腔具有良好的密封性和稳定性，成为石油、天然 气、压缩空气等能源储存的理想场所。"江苏省地质调查研究院正高级工程师刘志宏解释说。 盐穴具体是如何形成的？他告诉《科技周刊》记者，可食用的 ...

"'大规模盐穴储氢'主体工程的开工，是我国氢能产业发展史上的重要事件。"国家能源局科技司原副司长刘亚芳在开工仪式上评价，该项目填补了我国 大规模盐穴储氢领域的空白，同时将为破解氢能气态储存领域的"卡脖子"技术难题提供实践样本。 "大规模盐穴储氢"主体工程正式开工。科技日报记者 刘园园 摄 "大规模盐穴储氢"项目由中盐集团和清华大学合作，联合中国地质大学（北京）、中国科学院理化技术研究所、天津大学、中国矿业大学等多家单位共 同开展。该项目将形成具有自主知识产权的盐穴储氢全套技术体系，以推动盐穴储氢的规模化产业应用。 "储"是氢能产业发展的关键一环。作为全球最大的制氢国，我国在储氢环节仍存在补短板需求。 7月25日，由中盐集团与清华大学等单位合作的"大规模盐穴储氢"主体工程在江苏常州正式开工建设。这标志着我国在基于盐穴的大规模储氢领域迈出 了关键一步。 据悉，目前全国已投入使用的盐穴储气库中，中盐集团参与建设的数量达94％，这些储气库在我国天然气市场发挥了重要的调蓄和保障功能。"在此基 础上，我们积极探索盐穴在储能、储氢、储氦、液流电池等更多赛道、更广领域的应用，努力构建盐穴'多能并储'新格局。"李耀强表示。 " ...
