Element leads world class transport and energy stakeholders on V2G feasibility study

Posted on

 

Vehicle-to-grid (V2G) technologies could play a key role in the decarbonisation of Britain’s transport and energy systems. Connecting millions of EVs and coordinating their charging and discharging could minimise the costs of EV charging while allowing the grid to integrate high levels of variable renewable energy sources.

The feasibility study V2GB – Vehicle to Grid Britain led by Element Energy is part of the Vehicle-to-Grid competition, funded by the Office for Low Emission Vehicles (OLEV) and the department for Business, Energy and Industrial Strategy (BEIS), in partnership with Innovate UK.

Drawing on the diverse expertise of consortium members Nissan Technical Centre Europe, Energy Systems Catapult, Cenex, Western Power Distribution, National Grid ESO, Moixa and Element Energy, the project explores both near term niches and enduring large-scale opportunities for V2G to play a role in a flexible energy system in Britain.

Among the key conclusions of the project were the following

  • Residential V2G charging could be economically viable in the near term, but to do so will require a combination of high plug-in rates, reduction of the installation costs of high accuracy metering equipment for Firm Frequency Response (FFR), stacking of multiple revenue streams, and an agile model to move between revenue streams in a dynamic market environment.
  • To achieve wider uptake and contribute to energy system decarbonisation, the industry must reduce V2G hardware cost significantly, develop viable commercial models to depreciate the assets over 10 years, and remove consumer concerns about range and battery impacts.
  • A 7kW residential V2G charger could capture over £400/year in revenues, but only in ideal circumstances – a typical figure would be ca. £100/year.
  • The cost premium for 7kW V2G needs to drop below £1000 by 2030 for continued viability.
  • V2G could help to save £200m of cumulative distribution network investment by 2030.
  • Smart Charging could generate GB energy system net savings of £180m/annum, and V2G could save additional £40-90M annually in GB by 2030.

Element Energy produced a further report about their work package within the project, which lays out a road map for V2G in the time frame from 2020 – 2030, scaling up from a niche market to playing a more significant role in the GB power system. The report explores challenges and opportunities in technology and market evolution, the regulatory environment, and the development of business and ownership models addressing customer preferences and concerns. The analysis includes projections for V2G costs as well as revenues up to 2030 and an assessment on the changing relative importance of various energy markets for V2G business models. It uses Element Energy’s high resolution electricity system dispatch model to assess the impact of EVs on the British power system in 2030 across different scenarios.
