All of the key aspects of the technology – capturing the carbon dioxide, putting it into pipelines for shipment, and then depositing it underground – have already been demonstrated, but they have not yet been tried, and proven, on a large scale. There is strong evidence, however, that it would not cost the world huge amounts to undertake large-scale carbon capture and storage.
该技术的所有关键方面—二氧化碳的捕获，排入管道中以便进一步传输，以及最后放入地下—都已有所展示，但它还没有经过更大规模的试验和证实。但有足够的证据表明进行大规模的碳捕获和储存不会给世界带来过高的成本。
