ViridiCO2: Closing the carbon loop

ViridiCO2: Closing the carbon loop

ViridiCO2 is revolutionising the sustainability of chemical manufacturing processes by deriving products from carbon dioxide (CO2) feedstocks to close the carbon loop. Its innovative technology is able to directly replace fossil fuels used in the chemical manufacturing process, with repurposed CO2. By using waste CO2 in this way, it not only reduces emissions and fossil fuel reliance, it also serves as a CO2 utilisation strategy, rather than just a storage solution.

“During my PhD I focused on the design and manipulation of catalysts for chemical processes to make them more sustainable. Once it became clear this process had potential for commercial value, we applied for a patent in 2019. I knew I needed to create a company, but I really had no idea what I was doing.”

“I was thrilled to be accepted onto the ICURe programme. It far exceeded my expectations and gave me the time and opportunity to give the business my 100% focus. It has been invaluable, what we learned on the programme has become the foundation for everything we do now.”

“Coming out of ICURe we had a full business model and the validation of a vast network of people who wanted our product. The programme gave us an understanding of what we could provide and how we would provide it. Through the market validation phase we found that our CO2 utilisation technology is desperately needed. What we’re doing with ViridiCO2 will not only save manufactures millions of pounds but will also be a much more environmentally friendly solution.”

“Our target customers are chemical manufacturers. The chemical industry is one of the largest emitters of CO2 in the world. Our platform is poised to utilise waste CO2 that they generate and re-purpose it back into their own products, so it produces a circular economy. ICURe helped us identify our early adopter target market. I was also able to have meaningful conversations with all the biggest chemical manufacturers in the world. We met our leading client through the ICURe programme, a global multinational billion dollar company. We have developed this relationship and now we’re at the point of securing a pilot project with them.”

“In 2022 we completed our Innovate UK project on scaling the technology and putting it into some early adopters for validation. We went in wanting to prove that we could get one customer, and we actually got three customers. We validated it on site, and we’ve made a kilogram of our technology.”

“We successfully closed our £3 million seed funding round with EQT ventures to accelerate the development and commercialisation of our technology and to put it into pilot scale within the early adopters that we’ve identified. We have been run off our feet with commercial opportunities, with a lot of customers coming to us directly. We have just doubled our team, and plan to hire 3 more before the end of the year. We have a new lab, and we will shortly be moving into new offices at Southampton University.”

“We have built good relationships so the next step for us is to deliver into early adopter clients and build revenue streams. We will then prepare for a significant Series A raise in 2025 to really scale up.”
