Our Story
It’s our mission to make clean power accessible across the world, by ensuring it’s both economically and environmentally sustainable.
We believe that a net-zero society is within reach
And we want to get there as quickly as possible.
From design and finance to building and operating, we deliver circular battery solutions that capture renewable energy, balance its supply on the grid, transport it to our electric vehicles – then get repurposed at the end of their lifecycle.

Zero to full power in just 5 years
Since we began in 2017, we’ve raised £520 million in debt and equity funding and connected 442 MWh of batteries: that’s 262MWh supporting electric fleets and 180MWh supporting the grid, saving over 20,000 tonnes of CO2 per year.
Right from the start, our outlook has been firmly international. We have fast-growing operations in Benelux, Australia and New Zealand, and a global headquarters in the UK.
Today in the UK, we’re the leading owner and operator of battery storage. We are supporting the National Grid with the uptake of renewable power and are now working with 7 of the 8 major bus companies, powering 25% of the UK bus market.
We’re also the number one owner and operator of e-buses in Australia and New Zealand, and are quickly expanding into light commercial vehicles and trucks.
That’s all in just 5 years. So what’s next?
Our 2025 looks like
- 3,000 e-buses in operation: about 18% of all the buses in Belgium
- 1GW of battery power delivering grid services: equivalent to the power generated by 364 wind turbines
- 1 million tonnes of CO2 saved per year: the same as 500k return flights from Sydney to Phnom Penh
Partners that share our bold commitment
We work with clients and partners that are committed to driving real, quantifiable change. Whether that’s reducing greenhouse gas emissions and air pollution, securing affordable and reliable clean power or using batteries in innovative new ways.
Together, we make bold moves, balancing commercial and environmental priorities to reach net zero. From powering Scotland towards 100% renewable energy to delivering Australia’s largest electric bus project, you can read through our growing portfolio of international projects here.
An innovative team named after an innovative pioneer
Our name was inspired by Zénobe Théophile Gramme – 19th-century Belgian engineer and inventor of the first commercial electric generator, and whose dynamo powered French and British lighthouses.
We are an ambitious team of experienced power, technology and finance experts from diverse backgrounds and like our namesake, work to bring original and innovative solutions to practical and technical challenges.
