Australian vehicle-to-grid expert says research shows even greater benefits are possible

Dr Björn Sturmberg, who is the research leader of ANU’s Battery Storage and Grid Integration Program says vehicle-to-grid offers multifaceted solutions to Australia’s energy woes including reduced prices and increased grid resilience. Sturmberg thinks EV owners can get an even better deal than free charging when it comes to V2G.

“The opportunities for V2G to generate revenue in Australia are significant, due in no small part to the volatility of an electricity market with concentrated market power and aging fossil fuel generators as illustrated earlier this week in Victoria.” said Sturmberg.

On Wednesday after storms in Victoria cut transmission lines leaving 500,000 households without power, wholesale electricity prices spiked as high as $16,600/MWh.

Sturmberg thinks that V2G has the potential to provide a lot more financial benefit than free charging to EV owners.

Our research shows that the potential income from V2G will in many cases far exceed the cost of EV charging, meaning drivers ought to receive more than just free charging.”

He also believes EV owners should be incentivised to keep their vehicles connected as much as possible.

“For the grid – and thereby for the reliability and affordability of all Australian’s electricity supply – the most important aspect of EV usage is that EVs are plugged in to chargers (or a regular power outlet) as often as possible,” he says.

“This provides the greatest flexibility in their charging, to reduce the cost of electricity generation as well as, critically, the costs of network maintenance and emissions. This requires a shift in drivers’ behaviours, to habitually plug in their EVs whenever parked.”

Sturmberg says he wants to see innovation and trials of tariffs that provide incentives for every minute that EVs are plugged in and available for managed (‘smart’) charging and says this has the potential to be very effective even before including V2G.

On the impacts of V2G to EV battery life Stumberg thinks provided systems are well managed, there’s no need for concerns around battery degradation.

“The impact of V2G (and driving) on batteries is primarily determined by the state of charge of the battery and the rate at which power is injected or drawn out of the battery,” says Sturmberg.

“Well managed V2G, that keeps the state of charge of vehicles within batteries’ comfort zone (generally 30-80%), will have a very modest impact – and in some studies has been shown to improve battery health compared to unmanaged charging by reducing the amount of time that batteries are at a very high state of charge.”

Participation and sensemaking in electric vehicle field trials: A study of fleet vehicle-to-grid in Australia

We have just published a new article from the REVS V2G trial about how participants in a field trial – in this case, the fleet, sustainability and asset managers – make sense of and influence technologies when a group comes along wanting to deploy and test them.

We found unexpected effects which revealed insights about what configuration of V2G might be acceptable to fleet end users. If energy market participants want V2G to solve their problems (and make them profit), they need to do the flexibility work.

Abstract

Vehicle-to-grid is a niche technology that has the potential to benefit electricity markets and support more renewable energy in the grid. However, interest from prospective users in adopting V2G is not well understood, particularly in the context of fleet vehicles. Technology-oriented field trials can contribute to the development of niche technologies. Trials usually focus on making engineered systems work, institutional embedding and testing business models. However, through the participation of users they also provide the opportunity to explore processes of problem definition and the formation of social, ethical and cultural meanings. This article presents findings from the Realising Electric Vehicle-to-grid Services project, an Australian trial of vehicle-to-grid in a government-owned light passenger car fleet, aiming to explore co-productive processes as essential aspects of participatory technology development. Our data comprises interviews with organisational actors responsible for facilitating and mediating the trial, as well as others in similar organisational roles. Adopting ecologies of participation as a framework, it reveals the productive effects of these actors in mediating the local embedding of vehicle-to-grid. These findings challenge the framing of vehicle-to-grid as being a question of consumer acceptance and suggest that, for this promising technology to contribute to a more sustainable future, the electricity sector must accept more risk.

NRMA supporting the ANU Solar Car team and the BWSC (from Darwin to Adelaide)

“We see our (NRMA) partnership with the ANU Solar Racing Team and the Bridgestone World Solar Challenge as a great opportunity to support young people who are the leaders and policymakers of tomorrow. This is just one of many steps we’re taking to help Australian motorists in their transition towards an electric future.” NRMA CEO, Carly Irving-Dolan

ANU Project Lead Isaac Martin said the Solar Racing team had spent the last six years working to develop sustainable innovation within the ACT and were looking forward to working with the NRMA for the BWSC.

“Our team is so lucky to be made up of such diverse individuals from different backgrounds and experiences, and we’re excited to continue to push the boundaries of sustainable technology together,” Mr Martin said.

It’s wonderful to have The NRMA continue to support #electricvehicles and get behind Australia’s solar race (from Darwin to Adelaide) and the ANU Solar Racing team! The team’s making their final preparation for next week’s departure and I can’t wait to join them for the 3022km trip down the Stuart!

Video insight into the EnergiZine experiences

This has been one of the most engaging – and out there – projects I’ve ever had been involved in. It was an absolute privelidge to work with Brad Riley and collaborators in the First Nations Clean Energy Network on the content, Mitchell Whitelaw and Dave Fanner from the Engaged ANU on the creative engagement, and Tristan Schultz from Relative Creative who designed the richly layered absurdist mnemonic experience.

My speech from the events:

Let me add my respects to the Ngunnawal and Ngambri custodians of the beautiful and unceded land on which we’re gathered this evening and to all First Nations people who have cared for country since time immemorial.

The theme of tonight is wellness.

Everything you’ll be exposed to and will have to deliberate on and choose between effects your wellness and the wellness of your communities and the earth.

We don’t ever think or talk about our role at the ANU in terms of wellness, but really everything we do is in service of this goal: the wellness of individuals, communities, and the planet.

Now not everything you’ll find on these tables will assist with wellness. After all, a key part of wellness is avoiding that which makes you unwell: be that stress, junk food, pollution, etc.

And you can’t always trust what you read in wellness magazines and labels, you’ve got to critically investigate to uncover the complex interrelations and impacts of things.

This too is a vital part of our job at the ANU – to uncover and analyse that which makes people and places unwell. So keep an eye out for this tonight.

And with that, I wish you luck in nurturing, navigating, and crafting your wellness energy transition. I hope it’s as stimulating and engaging to complete as it’s been to create.

Response to Saul Griffith’s “The Wires That Bind”

This correspondence was originally published in the June 2023 edition of the Quarterly Essay, in response to the March 2023 edition by Saul Griffith.


While the pivotal role of electrification in decarbonisation has been understood for decades, it has rarely been described as vividly or enthusiastically as by Saul Griffith in The Wires That Bind. Griffith recognises that electrification is a story, at its heart, not about decarbonisation but about cleaning the air in our kitchens and streets, improving the liveability of our homes and communities, and “keeping wealth in our households and communities” – and nation. In short, electrification is a story about a better future.

While attuned to this human story of electrification, Griffith is, at heart, an engineer so it’s no surprise that The Wires That Bind is packed full of figures. Emissions are carved up, the grid is mapped and fossil machines are counted. This achieves Griffith’s goal of “clarity about the job in front of us” and complements his persuasive case for electrifying everything. The question that remains is: how can the transition best be accelerated and steered towards just and enduring outcomes?

A provocation – Who will drive Vehicle-to-Grid?

A “provocation” is my new favorite form of publication!

This article in Utility Magazine was a real pleasure to write and condenses many recent discussions.

Our main takeaway is this: “Our experience to date suggests that V2G may stand to be of greatest attraction “for the grid” and that there is much to be done “by the grid” to accelerate this innovation becoming a seamless part of the electric vehicle experience.”
