Where Firm‐Level Innovation and Industrial Policy Meet: Consensus Roadmaps for Low‐Carbon Powertrain Technologies

Environmental mandates, energy security concerns, and societal demands place considerable pressure on automotive manufacturers to develop novel powertrain technologies that reduce energy consumption, and in turn, carbon emissions. The economic case for these novel technologies is far from clear, however, and firms often turn to the respective national governments for R&D aid and demand‐side subsidies. Government on the other hand often feels unable to back any single technology for competition regulatory reasons, while at the same time being presented with conflicting messages from industry where to focus its support. This paper reports on an initiative by the U.K. Government that led to the establishment of a permanent forum for government‐industry exchange, the Automotive Council U.K., in which the author has participated from the outset. In the course of the Council's work, two “consensus roadmaps” have been developed jointly by industry and the U.K. Government to guide national efforts in the transition for both passenger car and commercial vehicle powertrain technologies toward low‐carbon alternatives. This paper discusses the key technological development stages and projections outlined in these technology roadmaps and comments on the general determinants of an effective interaction between government and industry in the light of a technological discontinuity.
