Meihong was trained as Process Engineer in China.He joined the Centre for Process Systems Engineering at Imperial College London in 1999 as Research Assistant (also part-time PhD at UCL), then Postdoctoral Research Fellow from in 2002. From 2004-2006 he worked as Senior Engineer in Alstom Power, UK. He joined Cranfield University as Lecturer in Process Systems Engineering and MSc Course Director on Carbon Capture and Transport in 2006 and held the post until 2012 before joining the University of Hull in 2012 as Reader. He was promoted to full Professor at University of Hull in 2014. In 2016, Meihong moved to the University of Sheffield as Professor of Energy Systems Engineering.
Meihong is a Chartered Engineer. He has published over 180 technical papers. One of his publications was awarded SAGE Best Paper Prize 2014 and Ludwig Mond Prize 2014 by IMechE. Another paper was given Award for the Most Cited Review Paper by Applied Energy Journal in 2016 (during ICAE2017 in Cardiff UK). Since 2006, Meihong has been involved in 21 research projects worth around £20 million from UK Research Councils (EPSRC and NERC), European Union (EU) and Industry as investigators (PI or CI). From 2014 2017, Meihong coordinated a project funded by EU FP7 Programme on International Research Staff Exchange Scheme (IRSES) with 40 research staff from 6 partners (3 from Europe and 3 from China). From 2014 to 2019, he led an EPSRC funded consortium project (worth £1.27 million) applying process intensification for carbon capture using solvents with flue gas from gas-fired CCGT power plants. Meihong became EPSRC Peer Review College Member in 2012. He is also an academic Member and also Scientific Council member of EPSRC funded UK CCS Research Centre (UKCCSRC), Member of Science Board in EPSRC funded Hydrogen and Fuel Cell (H2FC) SuperGen Hub and Member of the Science Board in the EPSRC funded Energy Storage SuperGen Hub. Since 2006, he has been involved in organising 8 international academic conferences.
Meihong currently leads the Process and Energy Systems Engineering Research Group at Department of Chemical & Biological Engineering, University of Sheffield with 14 researchers (including post-doctoral researchers, PhD researchers and visiting researchers).
