Scenarios for the development of smart grids in the UK: literature review
Smart grids are expected to play a central role in any transition to a low-carbon energy future, and much research is currently underway on practically every area of smart grids. However, it is evident that even basic aspects such as theoretical and operational definitions, are yet to be agreed upon and be clearly defined. Some aspects (efficient management of supply, including intermittent supply, two-way communication between the producer and user of electricity, use of IT technology to respond to and manage demand, and ensuring safe and secure electricity distribution) are more commonly accepted than others (such as smart meters) in defining what comprises a smart grid.
It is clear that smart grid developments enjoy political and financial support both at UK and EU levels, and from the majority of related industries. The reasons for this vary and include the hope that smart grids will facilitate the achievement of carbon reduction targets, create new employment opportunities, and reduce costs relevant to energy generation (fewer power stations) and distribution (fewer losses and better stability). However, smart grid development depends on additional factors, beyond the energy industry. These relate to issues of public acceptability of relevant technologies and associated risks (e.g. data safety, privacy, cyber security), pricing, competition, and regulation; implying the involvement of a wide range of players such as the industry, regulators and consumers.
The above constitute a complex set of variables and actors, and interactions between them. In order to best explore ways of possible deployment of smart grids, the use of scenarios is most adequate, as they can incorporate several parameters and variables into a coherent storyline. Scenarios have been previously used in the context of smart grids, but have traditionally focused on factors such as economic growth or policy evolution. Important additional socio-technical aspects of smart grids emerge from the literature review in this report and therefore need to be incorporated in our scenarios. These can be grouped into four (interlinked) main categories: supply side aspects, demand side aspects, policy and regulation, and technical aspects.

An Assessment of PIER Electric Grid Research 2003-2014 White Paper
This white paper describes the circumstances in California around the turn of the 21st century that led the California Energy Commission (CEC) to direct additional Public Interest Energy Research funds to address critical electric grid issues, especially those arising from integrating high penetrations of variable renewable generation with the electric grid. It contains an assessment of the beneficial science and technology advances of the resultant portfolio of electric grid research projects administered under the direction of the CEC by a competitively selected contractor, the University of California’s California Institute for Energy and the Environment, from 2003-2014

Maximizing societal benefits associated with alternative fuel subsidies: The Case of plug-in hybrid electric vehicles
Government seeks to improve the welfare of its citizenry and intervenes in marketplaces to maximize benefits when externalities are not captured. By analyzing how welfare changes from area to area across the country in response to the same intervention informs where government should act. This thesis analyzes the case of plug-in hybrid electric vehicles (PHEVs). PHEVs have many societal benefits, including improving national security, economic, environmental, and health advantages. The magnitude and distribution of these benefits depends on where PHEVs are deployed. This thesis develops and applies a methodology to determine if the benefits from PHEV deployment vary across the country and for ranking regions where positive PHEV consequences are likely to be maximized. The metrics in this method are proxies of key variables which predict the level of benefits in a county from the deployment of a PHEV there; they include population, health benefits from reduced ozone concentration, vehicle miles traveled per capita, existence of non-federal policies, and CO2 intensity of electricity. By shedding light on how benefits from PHEV deployment vary across counties, this thesis seeks to better inform where to enact government interventions to maximize the benefits of this technology
Battery Second Use: A Framework for Evaluating the Combination of Two Value Chains
A Battery Second Use (B2U) strategy is the design and development of a battery system with the intention of having it serve two purposes: (1) the initial use in the vehicle and (2) another mobile or stationary application. An optimal battery second use strategy requires the design and use of the battery to maximize the value of the system over its entire extended life cycle. Within this thesis a framework is developed which allows the evaluation of tradeoffs along the operational second use value chain
DEVELOPING A SMART AND SUSTAINABLE PUBLIC TRANSPORTATION SYSTEM: A CASE STUDY IN CAMDEN, NEW JERSEY
The transportation sector is a major contributor to air pollution and Greenhouse Gas (GHG) emissions. As a significant source of emissions, public transportation presents an opportunity for mitigation through electrification. However, transitioning to an electric bus fleet necessitates substantial investments in bus procurement and charging infrastructure. To address the associated costs, this study introduces a mixed-integer linear mathematical model developed to optimize the location of on-route fast charging stations within bus networks. The central objective of this optimization formulation is to minimize the overall cost of establishing the charging infrastructure. The study employs a real-world case study focusing on a Camden, NJ, USA bus network. Key considerations include optimizing charging station locations considering time constraints at bus stops to avoid schedule delays and inconvenience for passengers during the charging process. Furthermore, the study investigates the sensitivity of the optimization model in response to variations in parameters. Notably, battery capacity, charger power, average energy consumption, dwell time, and minimum and maximum state of charge significantly affect the optimal locations and required number of chargers. The insights generated from this study are anticipated to offer valuable guidance to policymakers, practitioners, and researchers involved in planning the transition of bus fleets towards zero-emission vehicles
Responsible Sourcing of Materials Required for a Resource Efficient and Low-carbon Society
Understanding future supply and demand of raw materials and the associated environmental and social implications is essential to supporting the transition towards greenhouse gas neutrality by 2050. In this Special Issue, we present a range of research papers with a focus on future outlooks of material supply and use, the consideration of associated environmental and social implications, and issues of raw material criticality and a circular economy. These are complemented by an editorial paper that provides, amongst other aspects, an overview of the corresponding policy and institutional framework. Knowledge of materials availability, their use patterns in modern economies, and associated environmental and social trade-offs is essential for informed decision-making in support of the necessary transition towards more resource-efficient and greenhouse-gas-neutral societies in the coming years
