The direct capture of CO2 from the atmosphere is a technology that will become essential to combat climate change. This can be done using either liquid solvents or solid adsorbents, where the solid adsorbents seem to present a number of advantages compared to solvents. The solid sorbent materials used for direct air capture of CO2 are mostly reactive materials, such as amine enhanced silica or alumina. There are currently a handful of start-up companies worldwide, who pioneer direct air capture with the use of solid, chemical adsorbents.
Standard adsorption-desorption cycles for direct air capture have been developed and are commercialised, but the investigation of direct air capture processes is just in its infancy. This implies that there is much room to develop more efficient or fit-for-purpose adsorption processes. An established way to do this is through mathematical modelling and simulation. During the PhD, the candidate will develop these models and will use them to investigate innovative cycles, which may lead to better performance in terms of energy consumption and costs. Work is based at Heriot-Watt, but some visits to industrial/academic partners may be necessary, we collaborate with a number of direct air capture companies. If so desired and subject to the modelling progressing well, there may also be room for either lab-based studies or more system analysis studies.
