Agustin has participated as PI/Co-I on 27 industrial projects with multi-nationals including PEMEX, Rolls-Royce, Siemens, Ricardo, Airbus and BP, attracting approx. £8.5M in research income. He has published 162 papers (h-index 22), 43 of these specifically concerning ammonia power. Dr 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 aimed to demonstrate the use of green ammonia as a hydrogen vector produced from wind energy. He is currently PI of various projects (Endeavr Green Propulsion, SAFE-AGT (EP/T009314/1), FLEXnCONFU (884157), etc.) to demonstrate ammonia power in turbines, furnaces and Internal Combustion Engines. 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 the preparation of two Royal Society Policy Briefings, an International White Paper for the Ammonia Energy Association on the use of ammonia as energy vector, and he is the principal author of the book “Techno-economic challenges of ammonia as energy vector (ELSEVIER)”.
