剑桥大学研究人员开发出一种新型低成本设备，可在充电时选择性地捕获二氧化碳气体。当它放电时，二氧化碳可以一种可控的方式释放，并被收集起来重新使用或以负责任地方式处理掉。

Researchers from the University of Cambridge have developed a low-cost device that can selectively capture carbon dioxide gas while it charges. Then, when it discharges, the CO2 can be released in a controlled way and collected to be reused or disposed of responsibly.

这种超级电容器装置类似于可充电电池，大约是一块2便士硬币大小，部分由可持续材料制成，包括椰子壳和海水。

The supercapacitor device, which is similar to a rechargeable battery, is the size of a two-pence coin, and is made in part from sustainable materials including coconut shells and seawater.

采用这种设计的超级电容器可以更低的成本进行碳捕获和存储。每年约有350亿吨二氧化碳被释放到大气中，因此迫切需要解决方案消除排放来解决气候危机。目前最先进的碳捕获技术耗能巨大且相当昂贵。

With such a design, the supercapacitor could help power carbon capture and storage technologies at much lower cost. Around 35 billion tonnes of CO2 are released into the atmosphere per year and solutions are urgently needed to eliminate these emissions and address the climate crisis. The most advanced carbon capture technologies currently require large amounts of energy and are expensive.
