[quote user="Railway Man"][quote user="Bucyrus"] <p>Tonight on CBS Evening News I heard that the future of coal is doomed unless a method is perfected to sequester the CO2, and the federal government should fund the research. I would think that the reward for developing a practical method of CO2 sequestration would be immense. Is not this reward sufficient to attract enough private capital to fund the research? </p><p>[/quote]</p><p>There's no issue with pumping CO2 into the ground; oil producers have been doing it for years. The issue is who takes the liability if it leaks back out, and when, and at what rate, and causing what damage. As yet there's no law to quantify that liability and no one is quite sure how to write it, either, since the science and engineering of long-term sequestration has no experience yet. I write a lot of contract language and public documents that the lawyers review, but ultimately they're relying on me to be the technical expert that tells them what's feasible and what's not.</p><p>RWM</p><p>[/quote]</p><p>Aside from the issue of pumping it into the ground, and the liability in case it leaks back out, where are we at in terms of capturing it from the combustion process of a mobile vehicle? I would think it would need to be captured and temporarily stored onboard the vehicle until it can be transferred to the permanent storage underground. What impact does this have on the economics of a locomotive pulling a train? </p>
