Four London-based companies have been named in the Sunday Times BGF 10 Green Tech to Watch, researched by Fast Track.

Published in the 20th anniversary edition of the Sunday Times Tech Track 100 ranking of the UK’s fastest-growing private tech companies, the inaugural 10 Green Tech to Watch list recognises private UK-based firms that are developing technology to help mitigate or reverse the effects of human activity on the environment, based on research sponsored by BGF – the UK’s most active investor in growing businesses

This year’s 10 Green Tech to Watch includes four London-based companies. These include Highview Power, which stores spare energy by cooling and liquefying air to -196˚C, releasing it to drive turbines and generate clean electricity; and EnvoPAP, which blends agricultural waste and wild grass fibres to create tree-free office paper and packaging materials.

Carbon Clean is a carbon capture technology developer which is cutting the cost of CO2 capture from industrial emissions by more than half. Meanwhile Whitefox Technologies has created an industrial membrane that is used in countries ranging from Germany to Guyana to efficiently remove excess water from biofuel production.

Stephen Welton, executive chairman of BGF, who helped judge the finalists, said, “As we come out of the Covid-19 crisis, a major and radical shift to new sectors of the economy is now going to happen much faster. Top of the list is the environment. Turning net-zero emissions pledges into reality is a huge opportunity for investors, but it requires a significant amount of capital. BGF plans to increase our investments into sustainable businesses from 5% today to up to 20% in the next 18 months. The 10 Green Tech to Watch is a great platform to showcase promising companies in this space.”
