Abstract

There is a growing body of literature that points to the significant potential of carbon capture and disposal technologies to help society address the challenge posed by climate change. In particular, carbon capture and disposal technologies appear to be a fundamental key in controlling the costs of addressing climate change and appear to be keys to facilitating the emergence of an affordable global hydrogen economy. This paper examines what the authors believe to be the current state-of-the-art in modeling these carbon capture and disposal technologies within large ?top-down? energy and economic models. The paper also examines the use of ?bottoms-up models? as a valuable compliment to these top-down models. Finally, the paper examines the insights that can be gained from both classes of models and what these models tell us about the deployment of carbon capture and disposal technologies in a greenhouse gas constrained world.
