The research Clea conducts is particularly pertinent to current and world affairs given the critical need for greenhouse gas emissions reduction in order to avoid dangerous climate change as recognized by the Paris Climate Agreement ratified by 141 parties. Carbon Capture and Storage (CCS) is recognized by key organisations, nations and companies such as the UNFCCC, the World Bank, the IPCC and IEA as being key to least cost climate change mitigation and facilitating a global phase out of a fossil-fuel based economy.
Clea's PhD research focuses on the integration of above ground CO2 capture and below ground CO2 storage, investigation the techno-economic factors that come into play when deploying CCS on a large-scale. Her research aims at linking the capturing system to the transport and injection of CO2 by analysing the effect of time-varying rates of CO2 capture and CO2 stream purity requirements as a function of the transport distance and injection sink e.g. depleted oil reservoirs and saline aquifers. The techno-economic potential of enhanced oil recovery (EOR) by CO2 injection in depleted oil reservoirs is also assessed using reservoir modelling software such as ECLIPSE and compared with the prospect of CO2 storage in saline aquifers.
Clea has collaborated with a number of institutions and companies including Stanford University, University College London, the British Geological Survey and Shell.
