New research shows that captured carbon dioxide can be stored safely for thousands of years by injecting the liquefied gas deep underground into the microscopic pore spaces of common rocks.

新的研究表明，捕获的二氧化碳可以通过液化注入到地下深层常见岩石的微观孔隙空间而安全存放数千年。

The findings – published in Nature Communications today – increase confidence in the widespread roll-out of engineered carbon capture and storage.

这一发现 - 今天在Nature Communications上发表 - 增加了对工程碳捕获和存储的广泛推广的信心。

In the study, researchers from Scottish Carbon Capture & Storage (SCCS), whose partner institutes include the Universities of Aberdeen and Edinburgh, compiled a worldwide database of information from natural carbon dioxide and methane accumulations and hydrocarbon industry experience – including engineered gas storage, decades of borehole injection, and laboratory experiments.

在这项研究中，来自苏格兰碳捕集与封存（SCCS）的研究人员，其合作机构包括阿伯丁大学和爱丁堡大学，编制了一份全球天然二氧化碳和甲烷积累信息数据库以及碳氢化合物行业经验 - 包括工程气体储存，数十年钻孔注射和实验室实验。

Computer simulations were used to combine all these factors and model storage of carbon dioxide for 10,000 years into the future. Previous research in this area had not fully accounted for the natural trapping of carbon dioxide in rock as microscopic bubbles, or the dissolving of carbon dioxide into the salty water already in the rocks.

计算机模拟被用于结合这些所有这些因素和二氧化碳模型储存在未来一万年之内。以前在这方面的研究并没有充分考虑岩石中二氧化碳的自然捕集作为微观气泡，或二氧化碳溶解到已经存在于岩石中的咸水中。

The UN Paris agreement has committed the world to limiting climate warming to well below 2°C from pre-industrial levels. This requires huge reductions in the amount of the greenhouse gas, carbon dioxide, which is released to the atmosphere from industry, electricity generation, heating and transport.

联合国巴黎协议已承诺全球将气候变暖限制在工业化前水平以下2°C以下。这需要大量减少从工业，发电，供暖和运输中释放到大气中的温室气体，二氧化碳的量。

Capturing these emissions and ensuring that carbon dioxide can be safely trapped underground is crucial for the successful protection of the atmosphere.

捕获这些排放物并确保二氧化碳可以安全地被困在地下对于成功保护大气至关重要。

Dr. Juan Alcalde, who co-led the research at the University of Aberdeen said: "The security of carbon dioxide storage is an understandable concern for people, communities and governments. Our work shows that the storage of carbon dioxide necessary to help address climate change can be secure for many thousands of years."

阿伯丁大学的研究人员Juan Alcalde博士说：“二氧化碳储存的安全性对人们，社区和政府来说是一个可以理解的问题。我们的工作表明，二氧化碳的储存是帮助解决气候问题数千年来，变化是可以保证的。“

Dr. Stephanie Flude who co-led the work at the University of Edinburgh said: "We selected the model inputs to be conservative but realistic. Importantly, our computer simulations, based on good-regulation practices, such as those used currently in the North Sea, retained more than 90 percent of the injected carbon dioxide after 10,000 years in 95 percent of the cases. The most probable outcome being at least 98 percent retention."

在爱丁堡大学共同领导工作的Stephanie Flude博士说：“我们选择的模型输入是保守但实际的。重要的是，我们的计算机模拟基于良好的监管实践，如目前在北方使用的那些在95％的病例中，海水在10,000年后保留了超过90％的二氧化碳注入，最可能的结果是至少保留了98％。“
