Carbon Capture and Storage (CCS) has been internationally recognised as the only way to curtail carbon dioxide emissions and limit global warming to within the IPCC's recommended limit of 1.5°C. Currently, commercial deployment of CCS is mainly limited by the efficiency of the 'capture' mechanism, (separating the CO2 from the rest of the flue gas stream). Application of current CCS technologies causes an unfeasible rise in the cost of electricity in most of the worlds economies.
Alex is working on developing a new carbon dioxide capture mechanism through adsorption on to carbon-based materials. When coupled with a vacuum-swing system, it is anticipated that these adsorbents will be more energy efficient at separating carbon dioxide than current commercially deployed amine scrubbing methods. Additionally, the raw feed-stock material can be manufactured from common waste materials, such as end of life tyres, biomass or sewage sludge.
In 2016, Alex graduated with a BSc in Environmental Geoscience from the University of Bristol. The following year, he graduated from Imperial College with an MSc in Environmental Engineering. After working as a Research Assistant at Imperial College in 2018, he started his PhD in 2019 and is supervised by Dr. Geoff Fowler. Alex is funded by the Science and Solutions for a Changing Planet scholarship, and Pyrenergy Ltd, an Energy-from-Waste (EfW) business.
