The circular economy for batteries

At Zenobē, we recognise that the path to net zero isn’t straight, it’s circular.

The path to net-zero isn’t straight, it’s circular.

We’re leading the transition to net zero and transforming the way organisations use power. By promoting a circular economy for batteries, we want to ensure our solutions will deliver CO2 and cost savings throughout their lifecycle.

From capturing renewable energy, balancing its supply and demand on the grid and transporting this power to our vehicle fleets, our solutions deliver value at each step.

Naturally, batteries degrade over time, but this doesn’t mean that their life needs to end there. By redeploying these batteries to provide stationary and portable energy storage solutions for remote locations such as Extreme E the loop can be closed and vital materials, carbon and value saved.

At the true end of a battery’s life, the majority of its valuable materials have the potential to, and should, be recycled. Powering the next generation of battery manufacturing.

Second-life battery supporting Aertssen’s on-site renewables

Zenobē partnered with Aertssen to maximise its on-site renewables using a second-life battery.

The Challenge

Renewable power is intermittent by its nature, only generating when the sun shines or the wind blows. For Belgian construction giant Aertssen, having installed 5,500 solar panels at its main office, they wanted to secure their supply of renewable power and manage energy price volatility.

The Solution

By installing the on-site battery, Zenobē is helping Aertssen to store surplus renewable energy generated by their solar panels and manage energy price volatility. The stored energy can be released to power Aertssen’s business operations, including its fleet of electric forklifts. Thanks to the battery the forklifts can run on renewable power at night without the need to buy energy at expensive periods of the day.

With years of experience balancing supply and demand for network operators in the UK, Zenobē is ensuring that Aertssen too can use renewable power more of the time, whilst saving money. Moreover, by redeploying an electric vehicle battery for a second life we’re closing the loop, saving vital materials, value and carbon.

“It marks the first time a second-life bus battery is used in Belgium to store renewable energy on site. It’s also a great demonstration of how EV batteries can be used to support the shift towards a zero-emissions future. We’re proud to be working with Aertssen on this exciting project. It’s an important step forward for Zenobē, Aertssen and for second-life batteries in Belgium.”

Tim Maeyens, Business Development Manager Green Energy for Aertssen

“Zenobe’s second-life battery ensures that the locally produced green energy is also stored and used locally. This is a step towards making Aertssen’s operations even more sustainable.”

Key Results

  • Security of supply – using more renewable power more of the time
  • Managing price volatility & save money: no need to buy back-up energy at expensive times of the day
  • Using solar energy when the sun doesn’t shine
