Leading energy provider E.ON and Superdielectrics, the Cambridge-based energy storage technology company, have announced they have entered into a wide-ranging collaboration agreement to promote and develop the British-developed battery solution, which is ultimately intended to give millions of homes access to safer, cheaper and cleaner power.

Central to the agreement is a shared vision between E.ON and Superdielectrics to develop the revolutionary polymer-based storage technology and renewable energy. This unique approach – the main component is a membrane similar to contact lens materials – means they are not only more affordable but also safer and more environmentally friendly.

This technology is aimed at giving customers more control of their energy use at home, ultimately lowering their electricity bills and helping to reduce fuel poverty in the UK. From its early trials, Superdielectrics estimates its technology could save UK consumers up to 85% on their domestic energy bills, while substantially reducing carbon emissions.

As one of the UK’s leading energy suppliers, E.ON can call on a wealth of data on the energy needs of millions of domestic and business customers, along with EV owners, enabling Superdielectrics to fine tune its technology, and accelerate the development of a more affordable electricity storage system for domestic use.

Jim Heathcote, Chief Executive of Superdielectrics, said: “We are delighted to sign this ground-breaking collaboration agreement with such a globally respected energy group as E.ON. Their support and insight will enable us to accelerate the development of our technology and bring it into production far sooner. We believe that our technology has the potential to revolutionise power generation and consumption and deliver enormous environmental and cost benefits to millions of people. We are all looking forward to working with them.”

Julian Lennertz, Chief Commercial Officer at E.ON Next, added: “The energy transition is about making energy more affordable and more sustainable, and to do that we’re always looking for and encouraging new technologies to make energy better for customers.

"Whether our approach is in-house or through partnerships, we’re always looking to come up with new ways to benefit our customers and to make new energy work for everyone. Superdielectrics’ technology could be a vital part of creating a cleaner, lower-cost energy future for everyone.”

Superdielectrics’ technology was demonstrated last year with the unveiling of the Faraday I, a breakthrough polymer-based battery. Superdielectrics’ system offers the following benefits:

Fast charging: Fully charges in just 30 minutes, compared to hours for other battery types

Low cost: The technology does not rely on rare metals, making its materials cheaper than lithium-ion batteries

Sustainability: Built with readily available, non-flammable, materials and easily recyclable

Long lifecycle: Comparable lifespan to existing batteries, with potential for even longer use

The demand for renewable energy is growing rapidly, so the need for energy storage has never been greater. Superdielectrics believes its system can compete with lithium-ion batteries in power, but without the same reliance on the mining of minerals which are needed for more traditional battery materials.

Superdielectrics is currently working on significant upgrades to its technology as it progresses towards commercial development and intends to make an important announcement about the development of its technology later in 2025.

About E.ON

E.ON's goal is to ensure the energy transition works for everyone. Through E.ON Next, E.ON Energy Infrastructure Solutions and npower Business Solutions, our mission is to help make energy more affordable and sustainable across homes, businesses, cities and communities.

Globally, E.ON is a major provider of energy solutions and clean energy networks with around 47 million customers across 17 countries. In the UK, we serve nearly one in seven households and businesses, and we are the UK's largest supplier of electricity to industrial clients.
