John, There is often discussion in various external communities about how technology will solve Global Warming. Personally, I’m not convinced. To me the Global Warming issue is the largest POLITICAL challenge mankind has ever faced. Shell certainly spends a lot of time on the technology aspects. Bearing in mind the possible future revenue from CCS - are we doing enough to influence Government

Response

John

I agree that this is not just a technology issue. I think Shell's efforts to help "the world" understand what needs to be done are generally appreciated, think of the planning scenarios we make and share, for example. But we do bring some unique things on the technology front, both sub-surface and surface. So its a balance, yes. Thanks for the question.

Wells go deeper, Injection cost will be higher. Do you determine the proper depth for CSS?

Response

Rich

Hi...thanks for the question. Yes, there are many different cost drivers for a CCS project, including the cost of capture, transportation, and injection into a secure subsurface container. Indeed, well depth is usually a smaller percentage of the expected cost of a typical CCS project. Regarding the specific question about well depth, there are many different technical considerations that go into the well depth. Our primary concern is long-term, safe containment, but of course adequate capacity is also a primary consideration.
