Professor Chris Rayner
Technical Director, C-Capture Ltd., and Professor of Organic Chemistry at the University of Leeds.
Chris Rayner is an organic chemist, and has been an academic at the University of Leeds for over 30 years. His research interests are centred around sustainability, with current focus on capture and utilisation of CO2 in chemical processes, and the use of natural products in consumer applications and in medicinal chemistry. He was promoted to Professor of Organic Chemistry in 2006, and has over 100 publications and patents. In the last 20 years he has made significant contributions to CO2 chemistry, including the concept of reaction tuning in supercritical CO2, and the use of CO2 in synthetic organic chemistry. He is Founder Director of C-Capture Ltd., which since its formation in 2009, has developed a fundamentally new solvent based approach for separating CO2 from other gases. Chris is also a co-Founder of Keracol Ltd., which uses sustainable methods for the use of natural products in consumer applications under the Dr Craft brand.

Carbon Capture, Utilisation and Storage (CCUS) will play a key role in achieving the IPCC goal to limit climate change to below 2°C, and making the UK net-zero of CO2 emissions by 2050. Although there are numerous different approaches to CO2 capture, the use of chemical solvents is the most developed given that similar technology has been used for natural gas sweetening (removal of CO2 and H2S from natural gas under pressure) for many years. However there are numerous drawbacks to the technology used, many of which arise from the scale of the problem of CO2 emissions.
C-Capture, a spin out from the Chemistry Department at Leeds University, has developed a new technology which uses significantly less energy than current commercial technologies for the CO2 separation process, utilising chemicals which are inexpensive, readily available, and environmentally benign. They are conducting Europe’s first Bioenergy with Carbon Capture and Storage (BECCS) demonstration project with Drax Power Station, Selby, which when deployed on scale, is a key negative emissions technology (NET) which has the potential to effectively remove CO2 from the atmosphere, whilst generating electricity.
The C-Capture process can remove CO2 from almost any gas stream, and so can be deployed at large scale CO2 emitters such as power stations (fuelled by gas, coal, and biomass), industrial manufacturing (glass, iron and steel, cement), hydrogen production (via steam methane reforming), natural gas sweetening and biogas upgrading.
