The Everything Electric Show has just released a new episode spotlighting Eleven Energy — and it’s all about how sodium-ion batteries are transforming home energy storage in the UK.
In the episode, presenter Imogen Bhogal visits Cambridge to explore two of our real-world installations: a 9 kWh and an impressive 36 kWh sodium battery system. Along the way, she speaks with Eleven Energy co-founders Andy Rankin and Neil French, as well as customers David Sargeant and Dr Lata Sahonta, who share their first-hand experience of living with sodium-ion storage.
The feature dives into:
- How sodium-ion batteries work — and why they’re safer, more sustainable, and better suited to UK homes
- The unique advantages of sodium: abundant materials, stable chemistry, and cold-weather performance down to –20 °C
- Our energy management system (EMS) that automatically adapts to tariffs, weather, and usage patterns to maximise savings
- The growing potential for sodium-ion to reduce reliance on imported lithium and support a more sustainable battery supply chain
“We wanted to create a battery system that performs exceptionally in British conditions, integrates seamlessly with solar and smart tariffs, and makes sustainable energy accessible to every homeowner,” explains co-founder Neil French.
