Driving Towards Tomorrow’s Campus with Vehicle-to-Grid EV Technology
As part of Flinders University’s drive to innovate and become a leader in climate action, the University launched its Vehicle-to-Grid (V2G) initiative. This involved installing and maintaining 20x V2G and smart chargers for its growing electric vehicle fleet. Leveraging 100% renewable energy generated by ENGIE’s Willogoleche Wind Farm and Flinders University’s solar power systems, this enables the storage of renewable energy in EV batteries to be discharged on campus during peak demand periods. Hence, allows for these EV fleets to operate as a Virtual Power Plant (VPP) to deliver peak demand management and optimization of behind-the-meter generation.
Overall, this initiative demonstrates the reliability and scalability of bi-directional and uni-directional smart-charging systems for EVs in reducing GHG emissions while facilitating teaching, research, and innovation opportunities. Moreover, it exemplifies a sustainable and innovative solution to scale energy storage technology and increase renewables.

Brandan Espe
Environmental Officer / Acting Grounds Supervisor
Brandan has brought over 50 federally listed Endangered species of plant into the James Cook University living collection, many of which have never been cultivated and are found in no other collection in the world.
Of these, over half have been sustainably wild collected, inclusive of field and clone data, so they can be used for ongoing conservation, research and teaching, the remaining being sourced from private and partner organisations through favours of service or trades.
He personally funded the project from 2019-2022, until funding was awarded for the program due to its success, with the program now being engrained into the Universities landscapes for ongoing management should he leave JCU, creating a threatened species legacy collection.
The program has now expanded beyond this, with an additional 48 species now funded for further addition, some of which are only known from less than 5 sightings in history.

Where knowledge meets habits: Empowering students for a sustainable tomorrow
Our online Sustainability Challenges offer participants an engaging, self-paced learning experience centered around a specific United Nations Sustainable Development Goal (UNSDG). Requiring minimal resourcing and at zero-cost to participants, we’ve created replicable, compact, scalable, and impactful learning opportunities that result in real impact.
The Challenges follow a structured process that moves participants from knowledge gain to simple action to celebration, to establish small but mighty habits relating to waste and carbon emissions. This approach recognises that knowledge alone is often insufficient to drive behaviour change, and that ease of action and celebration are crucial components in creating sustainable habits.
