Publisher Summary Diffusion of large-scale technologies requires coordination among manufacturers of those technologies supporting structures and products, consumers/buyers of the technologies, and governments who must support the diffusion process. This coordination must provide niche markets, within which the parties have the opportunity to develop the new technologies, shaping and correcting them so that they fulfill needs without creating new, insoluble problems. The clear advantages of the new technologies often appear only after their introduction and use in niche markets, that is, after a period of “learning-by-doing.” Analysis of the diffusion process becomes more complex and acute when environmental considerations feature prominently in the design of new technologies and when government-supported technology “push” is the dominant factor, rather than some known or presumed consumer need. Issues important to the diffusion of large-scale technologies for capturing and disposing of carbon dioxide include the extent/size of the system to be replaced, whether or not the new technology substitutes one-for-one for the old technology, the number of competing technologies, whether a market is an early or late adopter, specific initial conditions the availability of complementary technologies and affordable fuels, and the ability of inventors and entrepreneurs to solve problems that arise. These issues must be considered in planning for the diffusion of carbon capture and disposal systems.
