Dr Matter added: "You can find basalts on every continent and, certainly, you can find them offshore because all the oceanic crust - so below the seafloor - is all basaltic rocks.
　　Matter博士说：“每个大陆都有玄武岩，而且毫无疑问，近海也有很多这样的岩石，因为在海床下面的所有海洋外壳全是玄武岩。

　　In terms of the availability of basaltic rocks to take care of CO2 emissions globally - no problem."
　　要处理全球二氧化碳排放，在玄武岩的可供性方面，没有问题。”

　　There is, however, the issue of cost.
　　然而，费用是个问题。

　　Capture of the CO2 at power stations and other industrial complexes is expensive, and without incentives it is currently deemed to be uneconomic.
　　捕获二氧化碳到热电站或其他工业设备是昂贵的，没有这样做的动机的话，目前这是不经济的。”

　　The infrastructure needed to pump the gas to the burial site also has to be considered.
　　充气到埋藏点的所需设施也要被考虑到。

　　And in the case of the Carbfix approach, a substantial amount of water is required.
　　而且碳固定的办法，需要相当的水量。

　　Only something like 5% of the mass sent underground is CO2.
　　输送到地下的质量只有大概5%是二氧化碳。
　　Christopher Rochelle is an expert on CCS at the British Geological Survey and was not involved in the Iceland experiment.
　　英国地质调查的碳捕获和储存方面的专家Christopher Rochelle没有参与冰岛这项实验。

　　He said Carbfix underlined the importance of moving beyond modelling and lab studies to real-world demonstrations.
　　他说碳固定强调把模型和实验室研究转移到真实世界的重要性。

　　Only by doing this can the technology readiness be properly assessed.
　　只有这样，这项技术是否准备就绪才能得到适当的评估。

　　"We need to do more field-scale tests, like this one in Iceland, to better understand the types of processes that are ongoing and how fast they work," he told BBC News.
　　“我们需要做更多的实地测试，就像冰岛的这一项，以更好的认识这个过程中的类型，以及其速度，”他告诉BBC。(爱语吧)
