Scaling the UK’s next climate unicorns

What is the Net Zero X programme

The Net Zero X programme is designed to support the growth of climate tech companies with high-emissions reduction and exponential potential. The aim of the programme is to reduce the carbon funding gap, counter the climate tech ‘valley of death’ and connect climate tech founders to investors, corporates, partners, policy-makers and other stakeholders. This will help shape the ecosystem founders need to succeed.

Currently, only 25% of total funding raised in climate tech is being channelled into the technologies that hold 81% of the total emissions reduction potential required to achieve net zero. We are therefore very excited to be launching our new Net Zero X programme in partnership with PwC. Companies will benefit from Tech Nation and PwC’s expertise, investor & corporate network, and mentorship. 

The programme is free to join, and we don’t take an equity stake in your business. 

Net Zero X is not currently accepting applications, but you can pre-register your interest in the programme.

  • Solivus

    Solivus logo

    South East | Energy & Electricity | @solivus

    There are 2.5 billion metres squared of south-facing roofs in the UK alone. If half of these had solar, it would be enough to provide half the UK's electricity needs without the need to develop on greenfield sites. Solivus is an energy company decarbonising the planet starting with lightweight solar. Solivus wants to enable businesses, and - from next year - homeowners, to transition to cheaper, cleaner onsite energy generation for independent supply and control. In recent years, solar has progressed from a niche technology. Yet, we don’t see it on top of big stadiums, industrial estates or shopping centres. Many large buildings simply cannot take the weight of conventional solar and many homeowners do not like the look of solar on their roofs. The built environment contributes to 40% of global emissions. A new type of solar that is far lighter than conventional solar can turn low-load-bearing rooftops into high-energy generating assets.
