UK Spends £30 million on V2G Technology

As we reported back in the summer:

The United Kingdom Government… pledged to pump £20 million into vehicle-to-grid technology.

After an apparently interminable wait it was announced on Twitter yesterday that:

Today a plethora of press releases have added some flesh to those bare bones. According to UK Power Networks:

UK Power Networks is part of a consortium that has won £11m government funding for four electric vehicle demonstration projects as part of a series of Vehicle to Grid (V2G) innovation bids.

Vehicle to Grid technology enables energy stored in an electric vehicle’s battery to be fed back into the electricity network at times of peak demand. By recharging when demand is low and putting energy into the electricity network when it is high, V2G helps manage the peaks and troughs, balance the network and make it more efficient.

The government is to ban the sale of all new diesel and petrol cars and vans by 2040, and it sees a smarter and more flexible electricity system as a major benefit to consumers and a key enabler to transport’s future growth.

UK Power Networks currently has more than 30,000 electric vehicles connected to our networks and by 2030 we anticipate that figure will rise to between 1.2-1.9m. Many of these electric vehicles will be V2G capable and could be used to support delivering electricity reliably and at the lowest possible cost.

The competition is funded by the Department for Business, Energy and Industrial Strategy (BEIS) and the Office for Low Emission Vehicles (OLEV) and is delivered by Innovate UK.

The four V2G projects that UK Power Networks will be taking part in are:

  • Bus2Grid: Supporting a project to turn a 30-bus garage into the first of its kind in the UK Vehicle-to-grid (V2G) bus garage.
  • e4Future: A trial on 1,000 V2G fleet vehicles
  • Beating Home: Domestic customer V2G trial involving customers in specific areas.
  • V2Street: Public charging networks with a local authority and a charge point provider. Targeted at the 60-70% of Londoners without off-street charging capability.

Note that the £20 million on offer last August has been increased to £30 million today! Perhaps that’s at least a partial explanation for the delay in the appearance of the announcement? UKPN don’t provide much detail on the four out of twenty one projects revealed so far, so let’s look a bit further afield shall we? Heading back to Twitter there’s an announcement of a new product offering and a new EV web site from Octopus Energy unsurprisingly entitled Octopus Electric Vehicles:

which was swiftly followed by another Tweet explaining that:

which put us on the trail of this press release from ChargePoint Services:

Octopus Energy today launched a new consortium to develop the first large-scale domestic trial of vehicle-to-grid (V2G) charging in the UK, following a £3 million funding injection by BEIS and OLEV delivered by InnovateUK.

Comprising Octopus Energy, Octopus Electric Vehicles, UK Power Networks, ChargePoint Services, Open Energi, Energy Saving Trust and Navigant, the consortium will roll out vehicle-to-grid charging technology to UK electric vehicle (EV) drivers this year.

The £7million project will install 135 V2G chargers in a ‘cluster’ delivery model that will facilitate research into the impact of widespread EV rollout on the UK’s electricity grid. The project will demonstrate the benefits of using domestic electric vehicle batteries to provide grid flexibility, cheaper transport and energy to homeowners, and faster decarbonisation of the UK’s power and transport sectors.

Customers will be able to discover electric vehicles, take them for a test drive and access a special V2G bundle, Octopus PowerLoop, when leasing a V2G compatible car. A two-way charger will enable the driver to charge their vehicle intelligently, using their vehicle battery to power their home during peak times or selling spare power back to the grid – creating value for the driver.

The technology could revolutionise the energy system by enabling electric vehicles to act as battery packs for the grid, helping to solve the challenge of how to harness the full potential of renewable energy whilst making sure that it is always available on demand. Evidence also shows that V2G use has the potential to increase battery life.

The ChargePoint announcement goes on to quote Octopus Electric Vehicles CEO Fiona Howarth:

Octopus Energy was founded to drive down the cost of energy to customers and the planet, and Octopus Electric Vehicles is the next phase in that mission.

There has been a lot of talk from the sidelines about how vehicle-to-grid technology will change the face of energy, but with this consortium we will be the first in the UK to actually deliver it to hundreds of households. We’re delighted to be working with this consortium of visionary companies, and proud to be backed by Innovate UK.

It sounds as though the Octopus Group are intent on competing head on with OVO Energy who previously “embraced” V2G technology:

We’re hurtling towards a place where ‘two-way’ electric car chargers can enable homeowners with electric cars to sell their energy back to the national network. It’s a smart idea when you consider that over 90% of cars are parked at any one time – which is a lot of energy just sitting there doing nothing. This technology will give you the opportunity to manage your energy your way, and potentially become energy self-sufficient, reducing everyone’s reliance on energy companies. Get solar panels fitted, then adopt vehicle to grid technology and your home could become a private mini-power station!

There are a number of other quotes too. Mark Thompson, Senior Innovation Lead at Innovate UK added:

Vehicle-to-Grid is one of the most iconic parts of the electric vehicle domain, and one that represents a great opportunity for engaging society with the energy system for win-win benefit. The Octopus V2G project is part of a creative, diverse and ambitious group of V2G projects announced today that are way ahead of anything being done currently world-wide, and give the UK a genuine competitive edge in the electrification of transport.

Alex Bamberg, Managing Director, ChargePoint Services, said:

ChargePoint Services’ GeniePoint Network continues to be at the cutting edge of delivering the smartest and most reliable electric vehicle charging network in the UK. With this consortium, we join with existing partners to enable us to provide real benefits to the end user both in terms of efficiency and reduced cost. Our investment in the GeniePoint Network and its class leading reliability is further enhanced, whilst at the same time ensuring protection and flexibility of the UK’s energy Grid.

Ian Cameron, Head of Innovation at UK Power Networks said:

Electric vehicles are effectively energy sources on wheels, so there are tremendous opportunities to explore how electricity networks can use any spare capacity in those batteries to benefit our customers.

In the future you could use your car battery to power your house or earn money by selling its spare energy back into the network at peak times, and all of this whilst ensuring you have enough energy for your next day’s commute. We’re innovating to keep our customers moving at the lowest possible cost.

Dagoberto Cedillos, Strategy and Innovation Lead at Open Energi said:

Smart charging solutions that align the needs of drivers and the electricity grid are fundamental to the future of sustainable energy and transport. In partnership with our fellow consortium members, we’re applying cutting-edge tech to help realise the enormous opportunity that is domestic V2G charging in the UK, and internationally.

That is of course all very good news, but it raises one big question, in my mind at least. For some strange reason the Beating Home/PowerLoop (depending on which press release you prefer) consortium doesn’t seem to include a bi-directional electric vehicle charging point manufacturer and none of the assorted news releases and quotations mentions that rather essential piece of hardware, or indeed shows a picture of such equipment in action. To right that particular wrong, here’s one I prepared earlier:

A Exeter Nissan e-NV200 plugged in to the V2G charging station at EBRI

There’s also no mention of the activity that I’m currently engaged in. Developing international standards for the protocols that ChargePoint Services’s charging station management system (CSMS for short) might one day use to communicate with the unnamed electric vehicle supply equipment (EVSE for short) OEM’s V2G capable hardware installed in 135 Great British homes:

V2G and Energy Storage are in the News. In the UK!

Spring is in the air here in the United Kingdom. Several of the people I debate the future of distributed energy storage with on a regular basis have been in the news this week!

First up was Mark Thompson of Innovate UK. According to the headline in an article in Utility Week:

EVs are stable energy storage asset, says Innovate UK

The article goes on to explain that:

Innovate UK has brushed aside ongoing fears around using electric and plug-in vehicles as an energy storage facility, insisting they present a “car park of energy storage” for UK network companies after 2025.

Innovate UK’s lead technologist for energy systems Mark Thompson said at a recent storage event that fears that using EV batteries for grid support will rapidly degrade the batteries are unfounded. Innovation projects already undertaken into EV charging reveal the batteries will be accessible to the grid 95 per cent of the time.

Thompson said “a lot of anxiety” around using EVs as energy storage centres on battery recycling, but tests show that using an EV battery to provide 7kW of grid support is equivalent to driving at just 20mph.

Mark went on to point out:

That is a modest amount of power but aggregated would be very useful for a distribution network operator. The stress level on that battery of sitting there continually pushing out 7kW compared to a 35 minute journey is a no-brainer, it’s an extremely calm and un-stressful environment for that vehicle. Car manufacturer Nissan has been very vocal on the potential benefits of using EVs for grid support because there really isn’t an issue compared to the complexities and stresses that the battery goes through for a pretty normal driving scenario.

If we can be clever and come up with the right business models to engage people in moving their charging and allow network operators to have some control, if we can be savvy about that then network investment costs are virtually zero until you are well into the 2020s

Here’s one of Nissan’s infographics showing how they see the technology working:

UK Plc “being savvy” and providing support for the “right business models” is another matter entirely however! Utility Week continued:

Projects such as My Electric Avenue have revealed that vehicles are sat stationary at either the home or workplace, both potential charging locations, 95 percent of the time making EVs a “stable storage asset”. Based on “very modest projections” there could be as many as 300,000 EV or hybrid vehicles on UK roads by 2025, presenting around 4GW of potential storage to the UK’s electricity system with very little network reinforcement required.

Having discussed the Utility Week article with Mark Thompson it seems they have misinterpreted a couple of points:

I didn’t wish to imply that cars would be 95% available, just that they are “parked for 95% of the time” but that data DNO projects such as My Electric Avenue and ETI analysis indicate that a “very healthy proportion” of plugins will be accessible over the 24 hour cycle for grid support given charging and use patterns. The 95% figure as currently illustrated is not of course realistic, but perhaps eventually grid “connected availability” may be in the region of 30-60% depending on the time of day, which in time will amount to a significant amount of grid connected resource.

Also, the 4GW figure should be 4GWh.

Here’s the original slide from Mark’s presentation, with the correct units clearly visible on the Y axis and in big letters towards the end of the headline:

Today the mainstream media picked up the story in the form of an article by Damian Carrington in The Guardian entitled “From liquid air to supercapacitors, energy storage is finally poised for a breakthrough”. Damian opens with a quote from Jill Cainey, director of the UK’s Electricity Storage Network.

It doesn’t always rain when you need water, so we have reservoirs – but we don’t have the same system for electricity.

A battery project can take 12-18 months from saying we will do it, to completion. California is aggressively pursuing a low-carbon agenda and they don’t want diesel [generator back-up] on the system. Amber Rudd is talking a lot about energy storage, but we need a clear regulatory steer. The planes are circling, but there is no runway to land on.

Next Mark Thompson is quoted once again, apparently from the Utility Week article rather than from his actual presentation:

Using electric car batteries as a smart storage network while still in the cars is a promising option in the future, according to Mark Thompson at Innovate UK, a government agency. He says there could be 4GW capacity – a nuclear power station is about 1GW – by 2025 across the 300,000 electric cars projected to be on UK roads by then. He says cars are stationary for 95% of the time and using them could save billions of pounds, removing the need for new power stations and power lines.

However the article continues:

While interest in energy storage projects in the UK is surging – a recent call from National Grid for 200MW of short-term storage was oversubscribed six times – it is starting from a low base: just 24MW has been installed compared to the 5,000MW the government’s official advisers, the Committee on Climate Change, envisages in a low-carbon nation in 2030.

In November, energy secretary Amber Rudd said: “Locally generated energy supported by storage, interconnection and demand response, offers the possibility of a radically different model… We are looking at removing regulations that are holding back smart solutions, such as demand side response and storage.”

Removing the regulations that are holding back smart solutions is one of the reasons Mark and Jill were already on my list of people to call this week. That’s because DECC’s current consultation about how to “Ensure Regulation in the Energy Sector Encourages Innovation” closes on February 11th!
