EPRI, 8 automakers and 15 utilities to create an open grid integration platform for plug-in electric vehicles
July 29, 2014
The Electric Power Research Institute, 8 automakers and 15 utilities are working to develop and to demonstrate an open platform that would integrate plug-in electric vehicles (PEVs) with smart grid technologies enabling utilities to support PEV charging regardless of location. The open platform will simplify and streamline V2G (vehicle-to-grid) communications, enabling PEVs to provide grid services and increasing the overall value proposition of plug-in vehicles.
The goal of this program is to develop a cloud-based, central server that would receive grid requests from a utility—such as Demand Response—and then translate and standardize that request so it could be relayed to all appropriate plug-in vehicles in the designated area. Automakers would be expected to develop and deploy technologies compatible with these smart grid communications.

The California Independent System Operator Corporation (ISO) has released a blueprint for integrating electric vehicles (EVs) into the grid: “California Vehicle-Grid Integration Roadmap: Enabling Vehicle-based Grid Services”.
The VGI blueprint outlines three inter-dependent tracks to assess how consumer use of electric vehicles could benefit electric reliability, and to determine policies and technologies necessary to elicit that value through appropriate market signals for a more reliable, sustainable electric grid.
Honda joins vehicle-to-grid technology demonstration project in partnership with University of Delaware and NRG Energy
December 05, 2013
Honda has joined a demonstration project for experimental vehicle-to-grid (V2G) technology aimed at providing a potentially valuable energy storage resource to the electrical grid while providing for more cost-effective ownership of plug-in electric vehicles.
The Honda technology builds off of the research conducted by the University of Delaware and now supported by NRG Energy, Inc. through their eV2g joint venture (earlier post). eV2g came online early in 2013 with the first revenue-generating vehicle-to-grid project, demonstrating the controls, regulatory requirements, and market participation rules for selling energy storage from vehicles into the PJM Interconnection Regulation Market.

Navigant Research forecasts rapid growth in V2G for ancillary services to 2022; $190.7M in frequency regulation revenue by then
October 18, 2013
In a new report, Navigant Research forecasts that global vehicle-to-grid (V2G)-enabled plug-in electric vehicles (PEVs) servicing the ancillary services market will grow at a compound annual growth rate (CAGR) of 64.3% from 2013 to 2022.
In North America—which Navigant sees as the strongest initial market opportunity—Navigant sees frequency regulation revenue for PEVs growing from just more than $500,000 in 2013 to just less than $50 million in 2022. Globally, Navigant Research forecasts that frequency regulation revenue will reach $190.7 million by 2022. Navigant Research has not developed revenue forecasts for PEVs participating in demand response (DR) programs, as it is currently unclear how PEV owners will be compensated.

MIT researchers have engineered a new rechargeable, membrane-less hydrogen bromine laminar flow battery with high power density. The membrane-less design enables power densities of 0.795 W cm−2 at room temperature and atmospheric pressure, with a round-trip voltage efficiency of 92% at 25% of peak power.
That is about three times as much power per square centimeter as other membrane-less system—a power density that is an order of magnitude higher than that of many lithium-ion batteries and other commercial and experimental energy-storage systems. A paper on the work is published in Nature Communications.

Southern California Edison (SCE) released a white paper summarizing learnings from its Electric Vehicle (EV) readiness program. The paper, “Charged Up: Southern California Edison’s Key Learnings about Electric Vehicles, Our Customers and Grid Reliability,” shares information based on customer data and utility operations gathered since SCE began to prepare the distribution system and its customers for widespread electric vehicle (EV) adoption in its service territory.
Currently, SCE customers lease or own more than 12,000 plug-in electric vehicles (PEVs), both battery electric (BEVs, for about 35%) and plug-in hybrids (PHEVs, for about 65%)—about 10% of national EV sales. (SCE estimates that by 2020, there will be about 350,000 PEVs in its service territory.) Because California leads the nation in EV adoption, other utilities and stakeholders in the auto industry may find the information from the white paper useful, SCE suggested.

A recently published paper by M.J. Bradley & Associates, commissioned by the Regulatory Assistance Project (RAP) and the International Council on Clean Transportation (ICCT), examines key drivers of EV adoption in the US, Europe and China, with an emphasis on vehicle charging scenarios and infrastructure.
This report examines hurdles to EV adoption in these regions, and identifies critical success factors that should guide policymakers in the transportation and electric sectors. Accelerating the pace of EV market growth requires a coordinated evolution in both sectors, the report argues, from the power plant to the charging station to the vehicle. Supportive policies should work to ensure that EV owners are able to capture the full economic value of their decision to fuel switch from electricity to gasoline, including any benefits to the grid operator, and any emission reduction benefits, in addition to realizing the savings from replacing gasoline or diesel fuel with electricity.
