We’re thrilled to welcome Rhizo PTX Ltd to our innovative Surrey Research Park community.
Led by two former University of Surrey PhD researchers, the company is working to transform the chemical industry with its groundbreaking and Power-to-X technology for producing green ammonia.
Rhizo PTX was founded by Dr Ash Stott and Dr Ben Kyffin, who both hold PhDs from the University of Surrey, and several years of industrial experience – Ash in Electrochemical Devices and Ben in Advanced Materials Chemistry.
Their one-step electrochemical system directly transforms nitrogen and water into green ammonia, which refers to ammonia made with zero carbon emissions.
Rhizo PTX’s cutting-edge approach revolutionises current green ammonia production methods. By using a one-step process, it eliminates the need for green hydrogen – making the process more efficient, scalable and easier to power with renewable energy
Ammonia is the second most-produced chemical on the planet making up a $90 billion global market. It is currently used for many industrial processes such as fertiliser manufacturing.
However, production is highly carbon-intensive, accounting for around 2% of global greenhouse gas emissions. Green ammonia can decarbonise existing industries as well as provide a highly efficient zero-carbon fuel.
As more sectors seek alternatives to fossil fuels, the green ammonia market is now poised for major growth, with the industry expected to be worth over $250 billion by 2050. By scaling up its Power-to-X technology, Rhizo PTX aims to be well-positioned to capitalise on this growth, while making a significant step towards global decarbonisation.

Dr Ash Stott , co-founder and CEO said: “We are incredibly excited to establish our operations at Surrey Research Park, a hub of innovation and sustainability.
“The Park’s vibrant ecosystem and focus on clean energy solutions provide the perfect environment for us to further develop and scale our Power-to-X technology.
“We believe our process has the potential to fundamentally transform the energy and chemicals industries, offering a truly sustainable solution that will contribute significantly to global decarbonisation goals.”
Caroline Fleming, Director of the Surrey Innovation District ecosystem and innovation lead at Surrey Research Park, at the University of Surrey, said:
“We’re excited to welcome Rhizo PTX Ltd to our innovation community at the Park and to see Ash and Ben return to the University of Surrey.
“Their ingenuity and technical excellence are outstanding examples of the sustainability-led innovation that thrives here.
“By launching at Surrey Research Park, Rhizo PTX is primed for success, with flexible lab and office space and access to experienced business mentors through SETsquared Surrey.
Supporting sustainability goals and social impact are core to the University’s 2041 Vision, and we look forward to helping the team scale and succeed.”
