The Sustainable Process Systems Engineering Lab led by Prof. Gonzalo Guillén Gosálbez researches topics such as green supply chain management, sustainable process design, macro-economic models and sustainable energy systems design. Recent energy related research outputs include life cycle optimisation of Bioenergy with Carbon Capture & Storage (BECCS) supply chains, sustainability footprints of a renewable carbon transition for the petrochemical sector and uncovering the true cost of hydrogen production routes using life cycle monetisation.
