The objective of the Consumers, Vehicles and Energy Integration project is to inform UK Government and European policy and to help shape energy and automotive industry products, propositions and investment strategies. Additionally, it aims to develop an integrated set of analytical tools that models future market scenarios in order to test the impact of future policy, industry and societal choices.The project is made up of two stages:Stage 1 aims to characterize market and policy frameworks, business propositions, and the integrated vehicle and energy infrastructure system and technologies best suited to enabling a cost-effective UK energy system for low-carbon vehicles, using the amalgamated analytical toolset. Stage 2 aims to fill knowledge gaps and validate assumptions from Stage 1 through scientifically robust research, including real world trials with privatevehicle consumers and case studies with business fleets. A mainstream consumer uptake trial will be carried out to measure attitudes to PiVs after direct experience of them, and consumer charging trials will measure mainstream consumer PiV charging behaviours and responses to managed harging optionsThis report represents Deliverable D4.2, Final Analysis of Technology, Commercial and Market Building Blocks for Energy Infrastructure.The purpose of this report is to provide:A ‘first principles’ view of the key components or Building Blocks (BB) that are considered as part of understanding what technology/physical, actors/commercial, market/policy, and Customer Proposition structures are most effective in enabling mass deployment and use of ULEVs, and their relative importance.A systematic allocation of the BBs to the Narratives, in such a way as tofocus the framework on the areas of highest materiality, providing the basis for the analysis reported in the separate D1.3 Market Design and System Integration Report.The separate spreadsheet (accompanying this report) provides more details of the building blocks themselves.
