Carbon storage might not be so permanent Okay, as far as the concept of carbon capture and storage goes,  the idea -- technologically -- is intriguing. What many readers of this blog don't like is how the industry talks about this technology like it's here today so, hell, let's drill for even more oil and burn more coal. We're a decade away from seeing even just a small number of large-scale CCS projects in operation, so talk today of coal plants or oil-sand operations being "CCS-ready" is nothing more than greenwashing. I would imagine most people don't mind the Canadian government supporting R&D into CCS, but what they perhaps don't like is that the investment is being made to the exclusion of everything else. Why, it's reasonable to ask, take a silver-bullet approach to a technology that's a decade away? Would it not be better to balance it with near-term measures and investment in technologies that are here today? But let's assume, a decade out, that all the promise of CCS pans out. Let's assume it takes hold, that a vast network of pipelines is built, that we're certain sequestration sites won't leak, and that the percentage of CO2 we can capture from coal plants and industrial sites continues to improve. Let's assume that two decades out we start to see a number of acquifers and old oil fields filled to capacity with CO2 and, finally, capped shut. Think those storage sites will be forever permanent? Think again. I was
