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

At Zenobē, we recognise that 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 for National Express in Coventry

Zenobē provided an end-to-end, fully funded solution for bus operator National Express that seamlessly utilises recycled bus battery cells in an onsite battery energy storage system.

The Challenge

Birmingham-based multinational transport operator National Express Group plans to be a zero carbon bus company by 2030. As part of this plan, National Express sought to electrify its depot in Coventry to reduce carbon emissions, lower the quantity of harmful particulates released into the atmosphere, reduce noise pollution and lower operating costs.

The Solution

Zenobē developed an end-to-end solution for National Express including financing, batteries, chargers, and management software.

In addition to the many environmental and economic benefits of Zenobē’s turnkey solution, this project also seamlessly utilised recycled bus battery cells in an onsite battery energy storage system in a UK first.

Recycled bus power cells which were no longer capable of being used on buses are being repurposed into a stationary battery solution to provide power to electric vehicles and thus greatly extend their useful life. The stationary battery is a Time Shift B.V. 1MW/1.2MWh battery with second life BYD cells that were originally from buses operating in the Nordics. This new application will allow the battery life to be extended by around 30% resulting in less waste and lower replacement costs.
