Carmaker Honda is working with green energy supplier Good Energy and Salford University to investigate how vehicle-to-grid (V2G) technology could stabilise the national grid and cut costs for households.
The researchers, working in partnership with smart energy firm Upside Energy, will examine energy flows around a normal home that uses an electric car, to investigate how car batteries could be used by the grid to store and export energy in response to national demand.
The project – announced last week and dubbed ‘HAVEN’ – will be based at Salford University’s Energy House. The test home is the only one of its kind in the UK, and can simulate energy generation and use at different times of day and in different climates.
It will assess how well V2G technology can work with homes already using solar panels and batteries to generate and store their own energy, with the aim of developing the business case for V2G technology. As well as helping to manage peaks and troughs in national demand, V2G technology could also help householders earn extra cash by adapting their energy use patterns, the researchers argue.
“EVs, battery storage, V2G and now vehicle-to-home are all technologies that will be part of a decentralised energy system of the future,” Good Energy founder Juliet Davenport said. “This project uses Salford University’s Energy House, which means that we can truly see the impact for people’s homes, and their lives. I’m really excited to see what the findings are and how we can use to them to help our customers get to a cleaner, greener world.”
It forms part of a major government push into V2G technologies, with some £30m in government funding awarded to 21 V2G projects last month by Innovate UK, the Office for Low Emission Vehicles (OLEV) and the Department for Business, Energy and Industrial Strategy (BEIS).
A number of auto companies are investing heavily in support of the V2G model, with Nissan one of the other winners in the latest government-backed funding round. The company plans to install 1,000 V2G chargers to assess how business EV fleets could support a flexible regional grid.
