Hailed as a ‘wonder material’, graphene has captured the imaginations of scientists across a range of industries, with graphene companies operating in the aerospace, 3D printing, fashion, healthcare, and energy sectors. But we’d understand if you hadn’t heard of it just yet.
Graphene is effectively a thin sheet of graphite, made up of a single layer of bonded carbon atoms, arranged in a honeycomb lattice. Graphene and graphite are both carbon allotropes, structurally different forms of the same element. This structure is what gives graphene its unique properties: it’s an effective conductor of heat and electricity, absorbs light of all wavelengths, and is extremely light—yet stronger than steel.
With these properties making graphene such a versatile material, your next question might be why it’s not already widely used. The answer? Producing it cost-effectively, at scale, is still to be perfected. Serious headway has been made in recent years, however, with some major names now working with the material—Samsung is reportedly creating a phone with a graphene battery. First Graphene, a graphene producer, has become globally known as well as Applied Graphene Materials (AGM), which uses sustainable raw materials rather than graphite in its production process, Nanoxplore, which has a unique graphene production process that helps to produce it at scale, and Versarien, which creates graphene products such as 3D printers and ink.
At Beauhurst, we currently track 29 active graphene companies that are based in the UK and have hit at least one of our growth triggers. A further six companies have exited the market, whilst eight are no longer trading. Interestingly, 11 of the active graphene companies that are operating in the UK are based in the North West of England. In total, around 60% of high-growth graphene businesses are still in the Seed or Venture stage of evolution, reflecting how young the sector is—with the greatest growth in company numbers occurring between 2014 and 2017.
With that in mind, we’ve put together a list of the top 10 UK graphene companies for you to keep an eye on this year, based on the amount of equity investment they’ve raised to date.
