A whitepaper published by Imperial College London and Nissan, E.ON Drive shows the advantages of bi-directional charging EVs. The whitepaper says fleets that use vehicle-to-grid (V2G) charging are likely to cut down the power costs by £12,000 annually per EV and decrease more than 60 tonnes of carbon dioxide annually per EV. The whitepaper also suggests that the total power saving costs would be £410 million to £885 million annually.
The Nissan Motor GB’s managing director, Andrew Humberstone, said that the V2G system is essential both financially and environmentally. It has great potential to save power costs to vehicle fleets and system operators and cutting down carbon dioxide emissions all over the UK. The whitepaper asks for the incentives’ introduction to speed off the adoption of the vehicle-to-grid charging systems.
The paper also addresses the various challenges that are likely to be encountered at the early stages of the V2G, especially creating a reliable energy market. Imperial College and Nissan, E.ON Drive are partnering in the development of a commercial fleet V2G venture called e4Future that targets to show how EVs can do in support of the UK grid and offer a long-lasting solution to the business fleets.
The e4Future project is financed by the Office for Zero-Emission Vehicles (OZEV) and the Department for Business, Energy and Industrial Strategy (BEIS), in collaboration with Innovate UK. The project is in the V2G competition and the chair in the electrical energy programs at the Imperial College London, Professor Goran Strbac, said that according to the research they have conducted, it has revealed that V2G fleets can help improve system efficiency and decrease in new low-carbon production investment.
In 2018 January, OZEV and BEIS announced the 21 projects, which comprise 8 real-world V2G assessment projects, five research and production projects, as well as eight feasibility studies. The projects were to get financing of £30 million to come up with core technology and business proposition for the deployment of V2G in the UK. The projects have over 50 partners and research organizations from the automotive and energy sector.
The technology allows the flow of power in both directions, meaning from and to electric batteries. The power which is stored in the battery can be sold back to the grid, especially when the power demand is relatively high. Vehicles can charge when renewable production is high or when the demand is lower, decreasing the overreliance on fossil-fuelled production and decarbonization.https://minernews.io/
