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!

Community batteries are popular – but we have to make sure they actually help share power

New article in The Conversation today. Excerpt below.

The idea is for these batteries to reduce carbon emissions and energy bills while benefiting all energy users nearby, rather than only those with access to rooftop solar. These are great ambitions – small wonder they’ve proven a hit.

But the success of these batteries is far from certain.

Over the last four years, our research has found two areas we have to fix to maximise the chances these batteries actually do what we want them to do.

First, we need greater clarity on how we decide whether community batteries are a good investment.

Second, we need better measurement and evaluation of what these batteries actually contribute to the grid and to energy users.

In a new discussion paper, this article’s lead author argues the primary purpose of community batteries ought to be addressing constraint in the local electricity grid. This reiterates a consistent finding from our research.

While this sounds reasonable, community batteries aren’t the only option to fix local grid issues. That means we should only turn to them where they are clearly better than the alternatives, such as upgrading transformers.

What about storing solar and shoring up the grid? These tasks may be done more efficiently and with less environmental impact with grid-scale batteries, pumped hydro or electric vehicle batteries.

And what about sharing the benefits of solar with people who can’t afford an array or who have nowhere to put one? While this vision is in line with public sentiment, the complexity of the privatised energy system makes it very difficult to redistribute financial benefits.

Community batteries are also no panacea for the desire of people to see and be included in national planning for the decarbonisation transition. An inclusive planning process can address uncertainties in how the transition will affect us and our communities and ensure it upholds public values.

Time will tell if the newly announced Net Zero Authority will deliver this.

REVS project completion

This week marked the completion of the REVS project – the largest demonstration of vehilce-to-grid technology in Australia and foundational research on the integration of electric vehicles into the grid and people’s lives.

FACTS – a Framework for an Australian Clean Transport Strategy

I was part of a team of 18 independent experts (academics) who developed a comprehensive framework for decarbonising the Australian transport sector in a manner consistent with international best practice (eg shifting trips to public and active transport) and climate science to keep warming within 1.5d.

Below are some takeout snapshots. The full report is available at transportfacts.org and a summary was published in The Conversation.
