01The Story新闻事实

China has connected its first 100-megawatt-class compressed carbon dioxide energy storage facility to the grid in Xinjiang. The closed-loop system stores electricity during off-peak periods and releases power during demand peaks, with the project designed to support renewable energy integration and reduce coal use and carbon dioxide emissions.中国已在新疆将首个100兆瓦级压缩二氧化碳储能设施接入电网。该闭环系统在用电低谷储存电力、在需求高峰释放电力，项目旨在促进可再生能源并网，并减少标准煤使用和二氧化碳排放。

  • The facility is located in Mori Kazakh Autonomous County in Xinjiang Uygur Autonomous Region.该设施位于新疆维吾尔自治区木垒哈萨克自治县。
  • It can store 290 million kilowatt-hours of electricity during off-peak hours and discharge 180 million kilowatt-hours of green power during peak demand each year.该设施每年可在用电低谷储存2.9亿千瓦时电力，并在需求高峰释放1.8亿千瓦时绿色电力。
  • The system uses five gas holders, 141 liquid storage units and 97 thermal storage units.该系统配备5个储气罐、141个液体储存单元和97个蓄热单元。
  • The technology compresses carbon dioxide into a liquid during periods of low demand and expands it to drive power turbines when demand peaks.该技术在需求较低时将二氧化碳压缩成液体，在需求高峰时使其膨胀并驱动发电涡轮机。
  • Upon completion, the project is expected to generate about 200 million kilowatt-hours annually, save 50,000 tons of standard coal and reduce carbon dioxide emissions by about 170,000 tons each year.项目完工后预计每年发电约2亿千瓦时，节约5万吨标准煤，并减少约17万吨二氧化碳排放。

The project adds a large-scale storage option that can shift electricity across the day without relying on mountains or underground caverns.该项目提供了一种无需依赖山地或地下洞穴、能够跨时段调节电力的大规模储能方案。

Consequence影响推演

Storage capacity and grid balancing储能能力与电网调节

The facility is designed to absorb excess electricity during off-peak periods and release it during demand spikes. Its annual storage and discharge figures indicate its intended role in shifting power across the daily demand cycle.该设施旨在用电低谷吸收富余电力，并在需求激增时释放电力。其年度储电和放电数据表明，该项目定位于在每日需求周期中调节电力。

Annual electricity stored年储存电量

Annual electricity stored年储存电量290M kWh

Annual green power discharged年释放绿色电力180M kWh

  • The facility is connected to the grid at a 100-megawatt-class scale.该设施以100兆瓦级规模接入电网。
  • The project is designed to stabilize the local power grid during off-peak and peak periods.该项目旨在通过应对低谷和高峰时段的电力变化来稳定当地电网。
Comparison对比

Technology without site-specific geology不依赖特定地质条件的技术

Unlike pumped-hydro and compressed-air storage, the closed-loop system does not require mountains or underground caverns. This broadens the types of locations that could potentially host long-duration storage, although the source does not provide deployment plans beyond this project.与抽水蓄能和压缩空气储能不同，这种闭环系统不需要山地或地下洞穴。这扩大了长期储能潜在选址的类型，但来源未提供该项目之外的部署计划。

  • The system stores carbon dioxide as a liquid and later expands it to generate power through turbines.该系统将二氧化碳以液态储存，随后使其膨胀并通过涡轮机发电。
  • The project describes the technology as a low-cost and reliable alternative for long-duration grid storage.项目将该技术描述为长期电网储能的一种低成本、可靠替代方案。
