Carbon Capture, Utilisation and Storage

Lead supervisor: Dr. Mijndert van der Spek
Project partner: Yes, to be finalised

This is an experimental studentship in CO2 capture adsorption science in collaboration with instrument developer Surface Measurement Systems. Adsorbent-based carbon capture is an important means to reduce CO2 emissions from hard-to-abate industrial sectors and/or remove CO2 from the air. This type of technology needs to operate in real flue gases or air, where streams are made up of multiple components, critically nitrogen and water. Heriot Watt and Surface Measurement Systems have developed pioneering CO2-water co-adsorption measurement techniques, appropriate for certain adsorbent materials, while not for all. This studentship focuses on improving the existing analytical methods to achieve high-fidelity CO2-nitrogen-water co-adsorption measurements for a wide range of CO2 capture materials, critical to inform the rational design and optimisation of high-performing CO2 capture processes.

Accurate knowledge of CO2 streams density is vital across the CCUS chain, impacting engineering design, pipeline safety, reservoir management, and financial settlements. Unlike natural gas, which has a constant composition, CO2 streams are project specific and contain over 20 impurities across gas, liquid, and supercritical phases, complicating the development of an accurate and generalisable density Equation of State model (EoS). This is especially challenging near the critical point and the Widom line, where there are large gradients in fluid properties.
Current research suggests directly measuring the density of CO2-rich mixtures due to the limitations of existing EoS models. This project aims to develop two advanced methodologies for accurate and cost-effective CO2 density measurement. One approach combines stream speed of sound, pressure, temperature, and permittivity measurements, while the second integrates pressure, temperature, and speed of sound measurements with isentropic exponent predications from advanced EoS models. Both approaches are designed to be accurate, cost-effective, and easily deployable, as they utilize inputs — such as speed of sound, temperature, and pressure—already available from the existing commercial ultrasonic flow meters typically deployed across the transportation chain.
If successful, this methodology could be implemented in industrial settings with minimal hardware modifications, enhancing the efficiency and accuracy of CCUS technology deployment. Moreover, it has the potential to be applied to any other fluid including biogas, hydrogen, and ammonia.

This project will explore deep removal of CO2 from industrial sources (i.e., CO2 capture rates higher than 95%) and will focus on the development and assessment of novel electrochemical-regeneration methods that can be coupled to amine-based carbon capture technologies.

Green hydrogen and sustainable fuels/chemicals

Lead supervisor: Dr Omid Shahrokhi
Project partner: Not yet determined

The transition to a low-carbon energy system requires innovative solutions to repurpose existing infrastructure. This project explores how legacy oil and gas wells can be transformed into safe and efficient sites for underground hydrogen storage (UHS), a crucial component of renewable energy integration and decarbonization efforts. The focus is on assessing the integrity and suitability of legacy wells, addressing key challenges such as material compatibility with hydrogen, leakage risks, and pressure containment. The project will evaluate retrofitting techniques, advanced monitoring systems, and develop practical frameworks to ensure safe operations. Through analysis of existing field data, laboratory experiments, and computational modelling, this research aims to deliver actionable insights into the technical and regulatory requirements for repurposing legacy wells. By leveraging existing oil and gas assets, this work offers a cost-effective and environmentally sustainable alternative to developing new storage infrastructure.
This project contributes to the energy transition by facilitating large-scale hydrogen adoption, supporting industrial decarbonization, and enabling renewable energy storage. It also aligns with net-zero objectives, reduces environmental impact, and ensures legacy infrastructure plays a critical role in building a clean energy future. Join this pioneering effort to bridge traditional energy practices and sustainable innovation, ensuring a resilient and decarbonized energy system.

Systems integration

The amount of industrial waste has been increasing worldwide along with the global population, being considered as a main concern due to the impact not only to the environment but also to the human health and economy. This project will be focused on transform this industrial waste into added value products and green energy carriers by the utilisation of an energy efficient Magnetic Induction Catalytic system recently developed by our group. The project will aim to develop and test new magnetic catalysts based on earth-abundant and inexpensive transition metals such as Nickel, Cobalt and Iron as active supported nanoparticles. The textural and structural properties of the synthesised magnetic catalysis will be then studied and analysed by using different techniques such as X-ray, BET sorption analysis and FT-IR spectroscopy, among others. Then, they will be tested in different reactions at different conditions in order to obtain specific added value products and energy carriers such as Hydrogen or Biofuels, which will help to transit to a circular economy.

CO2 removals

Lead supervisor: Prof Phil Renforth
Project partner: Not yet determined

Concrete is a fundamental building material essential to economic development and a substantial contributor to greenhouse gas emissions during its production. Concrete reacts with atmospheric CO2 in all parts of its life cycle (during use, following demolition, and subsequent use). Accounting for passive CO2 uptake during the service life, and maximising uptake following demolition, together with deep emissions reduction in the production of cement could result in a net negative CO2 emission during its life cycle. This PhD project will explore this vital in-service life carbonation of concrete and its possible use for creating a net-negative carbon footprint.
