I am a second year PhD student at the Centre for Environmental Policy (CEP) and the Centre for Process Systems Engineering (CPSE). My PhD investigates the potential of negative emission technologies (NETs) for climate mitigation, with a focus on Bio-energy combined with carbon capture and geological storage (BECCS).
In particular, I evaluate the technical and environmental performance of BECCS throughout its value chain, which includes biomass supply chain, conversion to energy, and post-combustion CO2 capture. Through region-specific modelling and optimisation of BECCS value chain, the purpose of my PhD is to investigate whether BECCS can deliver negative emissions, energy, in a resource efficient way and within a relevant time frame for climate mitigation.
