Meet the CSEP Team Series: Dr Diego Freire Ordonez

Could you summarise your career journey so far?

I’m a Chemical Engineer with a background in process systems engineering, specialising in the techno-economic and environmental assessment of low-carbon technologies. My career has centred on understanding how we can design and scale sustainable production pathways for fuels and chemicals, particularly those derived from CO₂ and renewable energy. Before joining Imperial College London, I worked across both industry and academia—supporting projects in oil and gas, environmental regulation, and energy transition technologies for organisations in the UK, Europe, and Latin America. I hold a PhD in Chemical Engineering from Imperial and postgraduate degrees in energy and industrial management.

How do you see your work at CSEP contributing to real-world net-zero energy solutions? 

At CSEP, I have started working on the techno-economic assessment of different pathways for renewable syngas production. My work involves developing detailed process models and analysing the economic viability of emerging technologies that could replace fossil-based syngas in the future. What excites me most is the opportunity to explore pathways that are not only technically innovative but could also make a real contribution to a net-zero energy system. Seeing how small changes in design or integration can dramatically affect cost and sustainability is incredibly motivating.

What specific research topics or areas are you most passionate about?

I’m particularly passionate about CO₂ utilisation and the broader field of e-fuels—technologies that convert renewable electricity and captured carbon into low-carbon fuels and chemicals. I enjoy working at the intersection of engineering, economics, and environmental impact, where decisions are informed by a full systems perspective. Understanding how emerging technologies can scale, integrate into existing infrastructures, and ultimately compete with fossil-based processes is a challenge I find essential for the energy transition.

How does your focus on scale-up and integration of emerging technologies reflect CSEP’s vision of enabling sectors to innovate and grow?

I see my role as helping to deepen our understanding of the technologies that could shape the next generation of low-carbon fuels and chemicals. By analysing how emerging processes perform in practice—economically, technically, and environmentally—I hope to provide clarity on what is genuinely feasible as we transition away from fossil-based systems. My aim is to help generate insights that support better decisions, encourage innovation, and ultimately move us closer to a cleaner and more sustainable energy landscape.
