Levistor and the EIC Accelerator: Flywheels Beyond EV Charging

Levistor, a London company incorporated in 2021, builds flywheel energy storage, a "kinetic battery" originally developed at City, University of London. In June 2022 the EIC Accelerator selected it for a grant for a "flywheel grid boost for ultra-rapid EV charging", according to the EIC's list of selected companies. No project for this award appears on CORDIS.

In November 2024 Levistor announced its "first commercial product trials" at National Highways' test centre at Moreton-in-Marsh from early 2025, to see whether the flywheel could support high-power charging where the motorway grid is too weak, Renewable Energy Magazine reported. By 2026 its website described the business as "smoothing damaging power pulses for industry", with EV charging one of several applications. Its accounts at Companies House show £162,789 in cash in February 2025, down from £708,167 two years earlier.

Where Levistor Stands Now

Levistor now groups its market into four "power problems": filtering transients in data centres and crushers, shaving peaks for cranes and presses, recovering braking energy on railways, and boosting power for EV charging hubs, lasers and fusion. It says every engagement starts with measuring a customer's power profile, and that solutions are "never sold off the shelf". Its website does not report the National Highways trial results or name customers. Companies House records share allotments in November 2025, February 2026 and May 2026.

The Technology: Storing Energy in a Spinning Mass

A flywheel charges slowly from the grid by spinning up, then releases power in bursts. For EV charging, Levistor said it would let a driver add 100 miles of range in five minutes where the grid alone cannot supply the power. The company claims millisecond response, more than 3 million cycles without measurable degradation and an operating life of over 20 years.

What the EIC Project Promised, and What CORDIS Shows

The award was for grid boosting for ultra-rapid EV charging. The National Highways trial was set up to test exactly that. But CORDIS has no grant agreement, so there is no budget, work plan or report, and the trial's results are not public.

The Money

Levistor files abridged accounts without a profit and loss account. Its accumulated losses rose from £1.14 million in February 2023 to £1.84 million in February 2025, and share premium from £1.75 million to £2.26 million. Net assets fell to £420,231. Accounts for the six months to August 2025 are due by 24 November 2026.

What Cannot Be Checked

Why Europe Should Care

Motorway service operators such as Moto have asked the UK government to make grid access along all 2,300 miles of motorway a national priority, Renewable Energy Magazine reported. Storage that bridges the gap could let fast chargers open sooner. The EIC selected Levistor's answer, but the company now pitches it mostly elsewhere.
