Professor Agustin Valera-Medina has participated as PI/Co-I on 33 industrial projects with multi-nationals including PEMEX, Rolls-Royce, Siemens, Ricardo, Airbus and FloGas (>£35M). He has published 229 papers (h-index 42), 95 of these specifically concerning ammonia power. Prof. Valera-Medina led Cardiff’s contribution to the Innovate-UK ‘Decoupled Green Energy’ Project (2015-2018) led by Siemens and in partnership with STFC and the University of Oxford, which aims to demonstrate the use of green ammonia produced from wind energy. He is currently PI of various projects (SAFE-AGT, FLEXnCONFU, OceanREFuel, MariNH3, CaipiriNH3a, etc.) to demonstrate ammonia power in turbine engines, Internal Combustion Engines and furnaces. He has been part of various scientific boards, chairing sessions in international conferences and moderating large industrial panels on the topic of “Ammonia for Direct Use”. He has supported two Royal Society Policy Briefings related to the use of ammonia as energy vector, and he is the principal author of the books “Techno-economic challenges of ammonia as energy vector” and "Ammonia Combustion Applications". He is Co-Director of the Institute of Net Zero Innovation and Director of the Centre of Excellence on Ammonia Technologies (CEAT), Cardiff University. He is a Fellow of the Learned Society of Wales (2024).
