Diarmaid Clery


I graduated from the University of Leeds in 2013 with a MEng in Mechanical Engineering. This course provided me with a vast range of engineering experience in many different application such as biomedical, robotics, health, automotive and electrical. Upon graduation I started work as a graduate piping engineer for Foster Wheeler Energy. I learnt a lot about the energy industry and international engineering projects form my time at Foster Wheeler, however I felt a desire to work on more future looking projects – such as renewable energy.

Research interests

The main focus of my PhD examines the impacts of flue gas composition from biomass combustion on the solvents used for carbon capture and storage (CCS). The combination of bioenergy and carbon capture and storage (BECCS) provides the potential to create negative carbon dioxide emissions from power and heat generation. The technology has been highlighted as an invaluable technology to assist in urgently lowering carbon dioxide emissions by the many international advisory bodies, such as the IPCC, IEA and CCC.

It is anticipated that some of the biomass flue gas components may have a negative effect on the solvents used for the capture of carbon dioxide. Firstly, the effects of potassium compounds will be examined due to their known negative effects on slagging and fouling in furnaces. Fuel, ash characterisation and gas analysis techniques will be used to track impurities throughout the combustion and capture process. Further in-situ experiments are planned at the Pilot-scale Advanced Capture Technology (PACT) facilities in Sheffield and potentially other UK power stations.
