V2G

Vehicle to Grid (V2G) technology could generate additional revenue of up to $2 billion for global utilities by 2025, according to a new study conducted by ABI Research.

The study says the technology could enable consumers to save up to $272 per year on their energy bills.

V2G is not only expected to help consumers save up to 15% on their bills but also to help them shift heavy energy use from peak to off-peak, therefore ensuring grid reliabilities.

Up to 21TWh of the 585TWh of spare energy from electric vehicles is expected to be distributed to the grid via V2G in 2025.

V2G is expected to help the industry to expand renewable energy use, provide grid-critical additional resources for primary and secondary frequency control, as well as help grid operators better manage line constraints and forecast demand.

Shiv Patel, a research analyst at ABI Research, said: "V2G could be a real game-changer in how energy is not only consumed but also generated".

Lack of Original Equipment Manufacturer support is the biggest barrier to adoption.

However, stakeholders are coming together to develop roadmaps and solutions on how to improve technology uptake.

For instance, the China Electricity Council and the CHAdeMO association have decided to unify their charging standards to allow V2G to become available on the most popular charging standard in the world, GB/T.

OVO Energy, a UK energy supplier is working on launching a home-charger for V2G in partnership with Nissan later this year.

Meanwhile, aggregator, Nuvve and charging infrastructure supplier New Motion are both trialing frequency control services with grid operator TenneT, while also working to ensure that these services are optimised for the grid.

  1. So for V2G, what assurances does the system operator have that the vehicle will be parked in the right spot and ready to discharge at the right rate and amount for this to help the grid? For the EV driver, what assurances does the driver have that they can use the vehicle for their next driving stint, and not pay more for recharging the battery at a later time or for battery health degradation? What infrastructure is needed and at what cost for the little bits of energy to flow back into the grid? Are there alternative solutions to achieve the same objective and have money invested in V2G provide a better benefit if used for improving other technologies (i.e., for EVSEs, EVs, or shoring up the grid)? Technically, V2X is very possible, but practically, there are many questions that need to be answered for me to be won over.
