### English
* **Grid Strain from Extreme Weather:** Frequent and prolonged heatwaves are exposing the limitations of current Battery Energy Storage Systems (BESS), which typically offer only 1 to 4 hours of duration.
* **Shift Toward LDES:** To handle extreme peak demands and stabilize the grid, industry experts suggest a transition toward Long-Duration Energy Storage (LDES).
* **Infrastructure Replacement:** Approximately 70% of US power generation capacity is expected to reach retirement age by 2035, necessitating a shift toward renewable energy supported by reliable LDES.
* **Data Center Impact:** Rapid growth in data centers is placing unprecedented pressure on power infrastructure, with consumption projected to double or triple by 2028.
* **Operational Constraints:** Unlike residential users, data centers operate near full capacity, meaning they may be forced to reduce computing output during heatwaves when cooling demands surge.
* **Flow Battery Innovation:** Companies like XL Batteries are developing pH-neutral flow batteries using organic molecules as a sustainable, scalable alternative to traditional vanadium-based systems.

* **极端天气引发的电网压力：** 频繁且持续的极端高温天气正在暴露出当前电池储能系统（BESS）的局限性，目前的储能时长通常仅为 1 到 4 小时。
* **转向长时储能（LDES）：** 为了应对极端峰值需求并稳定电网，行业专家建议向长时储能（LDES）转型。
* **基础设施更新：** 预计到 2035 年，美国约 70% 的发电产能将达到退休年限，这要求能源行业向依赖长时储能支撑的可再生能源转型。
* **数据中心的影响：** 数据中心的快速扩张正对电力基础设施施加巨大压力，预计到 2028 年，其能耗可能会翻倍或增加至原来的三倍。
* **运营限制：** 与居民用户不同，数据中心通常处于接近满负荷运行状态，这意味着在热浪期间，由于冷却需求激增，它们可能被迫降低计算功率。
* **液流电池创新：** 像 XL Batteries 这样的公司正在开发使用有机分子的 pH 中性液流电池，作为传统钒电池的一种可持续、可扩展的替代方案。
