Thomas Brenas

Hydrogen Process Department Head TotalEnergies


After obtaining my master's degree of chemist engineer specialized in Chemical Engineering from École Nationale Supérieure de Chimie de Paris (E.N.S.C.P) in June 2002, I joined the process department of SAIPEM France. I worked for 6 years in upstream Oil & Gas projects as process engineer. I joined the Total group in 2008 as senior process engineer working on the design and to support operations of upstream O&G assets. I spent 4 years as head of planning development team in Total Gabon from 2015 till 2019. Back to TotalEnergies headquarter, I started to work on Carbon Capture and Sequestration projects including blue hydrogen projects. After September 2021 reorganisation and technical branch OneTech creation, I took the head of H2 & NH3 process team in the Gas & Low Carbon department of the Process Technical Line based in Paris. My team is in charge of all the process studies related to low carbon hydrogen production, the transport vectors such as NH3 or LOHC and the usage of ammonia and others.
