The first step to a circular economy for batteries in New Zealand

Energy Futures

Batteries lie at the heart of a renewable energy future: powering electric cars, storing solar-generated electricity and much more besides. But how to tackle the problem of their limited lifespan? GNS Science Energy Future experts are on the case.

New Zealand’s objective of electrifying its transport infrastructure carries with it an environmental consequence – in the form of a growing waste stream of used rechargeable batteries. In August, GNS Science hosted a group of influencers from the energy, recycling and transport sectors along with a group of government officials. Their shared aim: to lay the foundations for a reuse and recycling path for Aotearoa New Zealand.

Creating a circular economy for batteries in New Zealand would be a big step towards a low-carbon future. Workshop participants shared ideas about technology and industry needs and agreed on GNS’ proposed outcome-focused approach. They devised a roadmap for the next steps – apply for research and development funding to discover a non-destructive way to revitalise batteries for electric vehicles, as well as research the bigger picture of battery reuse and recycling in New Zealand.

Commercial viability will be central to these research outcomes, so industry input will be crucial. We’ve had some great feedback from the battery industry, car manufacturers and transport infrastructure agencies keen to get involved – watch this space.

Hapū partnership valuable for all at Ohaki

Two years ago, GNS started working with a local land trust at Ohaki to better understand the sustainability of their land to establish an eco-friendly papakāinga (housing settlement) in degraded geothermal environments.
