Prof Maroto-Valer (FRSE, FIChemE, FRSC, FRSA, FEI) is leading the development of the UK Industrial Decarbonisation Research and Innovation Centre (IDRIC).  She is also Associate Principal (Global Sustainability) and Director of the Research Centre for Carbon Solutions (RCCS) at Heriot-Wat University.

Mercedes has held academic appointments at the University of Kentucky (1997-1998), Pennsylvania State University (1998-2004), University of Nottingham (2005-2012) and Heriot-Watt University (2012-now). Mercedes obtained her PhD in 1997 at the University of Strathclyde (Scotland). Following a one-year postdoctoral fellowship at the Centre for Applied Energy Research (CAER) at the University of Kentucky in US, she moved to the Pennsylvania State University in US, where she worked as Research Fellow and from 2001 as Assistant Professor and became Program Coordinator for Sustainable Energy. She joined the University of Nottingham as Reader in 2005 and within 3 years she was promoted to Professor in Energy Technologies. During her time at Nottingham she was the Head of the Energy and Sustainability Research Division at the Faculty of Engineering. She joined Heriot-Watt University in 2012 as the first Robert Buchan Chair in Sustainable Engineering and she has been Director of the cross-university Energy Academy and Head of the Institute of Mechanical, Process and Energy Engineering. 

She is Director of the Research Centre for Carbon Solutions (RCCS) comprising over 50 researchers and an active research portfolio of >£17m. RCCS is a world leading engineering centre delivering innovation for the wider deployment of low-carbon energy systems required for meeting carbon targets, including carbon capture, conversion, transport and storage; emissions control, low carbon fuels and process/systems integration. She has over 500 publications, including editor of 4 books and 25% of her publications are in top 10% most cited worldwide. She holds leading positions in professional societies and editorial boards and currently serves as President Environment, Sustainability and Energy Division - Royal Society Chemistry (RSC), Editor-in-Chief Greenhouse Gases: Science and Technology, Member of the British Geological Survey (BGS) Advisory Committee, Board Member of the Energy Technologies Partnership (ETP), Royal Academy of Engineering (RAEng) Frontiers of Engineering Steering Group, Member Communities Board-Royal Society Chemistry (RSC), and Institute Chemical Engineers (IChemE) Energy Centre - The Leadership Forum. She has received numerous international prizes and awards, including 2020 WES Top 50 Women in Engineering (WE50) Sustainability, 2019 Scottish Women Award - Services to Science and Technology, 2019 Honorary Doctorate by Technical University Delft, 2018 SRUK/CERU Merit Award (Society of Spanish Researchers in the UK), 2013 Hong-Kong University Mong Distinguished Fellowship, 2011 RSC Environment, Sustainability and Energy Division Early Career Award, 2009 Philip Leverhulme Prize, 2005 US Department of Energy Award for Innovative Development, 1997 Ritchie Prize, 1996 Glenn Award- Fuel Chemistry Division of the American Chemical Society and the 1993 ICI Chemical & Polymers Group Andersonian Centenary Prize.  Her research portfolio has included as PI/CI projects worth ~ £35m, and has recently been awarded a prestigious European Research Council (ERC) Advanced Award.

In her role as Assistant Deputy Principal (Research and Innovation), her key strategic responsibilities included leading the development of university wide initiatives to support global research activities, as well as development of strategic partnerships to support innovation. She also contributes to the development and successful delivery and implementation of the University’s Research and Innovation strategy.

Since 2019, she is Associate Principal for Global Sustainability at Heriot-Watt, providing leadership for the University’s approach to sustainability across our global community.

Roles & Responsibilities:

  • Associate Principal (Global Sustainability)

  • Robert M Buchan Chair in Sustainable Energy Engineering

  • Director Research Centre for Carbon Solutions (RCCS)
  • Assistant Deputy Principal (Research and Innovation), 2017-2019

  • Director of Energy Academy, 2013-2017

Research interests:

Prof Maroto-Valer’s research at the interface of engineering and science is strongly linked to leading international collaborators and has resulted in notable outputs. She has established an international research reputation at the interface between energy and the environment. 

  1. Development of novel, low-cost sorbents for low- and high-temperature CO2 capture for power (pre- and post-combustion) and industrial sectors.
  2. Experimental and modelling studies on the mineralogical changes and fluid chemistry derived from the injection of CO2 and co-injection of gas mixtures (e.g. CO2-SO2).
  3. Geological sequestration of CO2 in saline aquifers, brines and unmineable coal seams.Integration of CCS and CO2 utilisation for the oil and gas sectors, e.g. enhanced-oil-recovery (EOR).
  4. Monitoring, measuring and verification of potential effects on aquatic and terrestrial environments of potential seepage from CO2 storage sites or pipelines.
  5. Decentralised options for CCS, including mineral carbonation of industrial wastes and silicate rocks.
  6. Development of systems (nanostructures and reactors) for CO2 photoreduction and other processes for CO2 utilisation.
  7. Gas clean-up, including trace metals (mercury etc), NOx/SOx, by-products for combustion and gasification.
  8. Public acceptability and regulatory issues related to CCS.
