This work package is dedicated to identifying and producing CO₂ capture materials that can compete with the current – though not satisfactory – benchmark in the field. The potential for scale up of these materials is to be explored using unique facilities available at UK universities.

Using the PACT facilities we'll investigate a range of biomass fuels coupled with different CCS technologies, including post-combustion & oxy-fuel methods. This is vital for scaling up projects to a larger commercial scale to make a real world impact on emissions reductions. This work package investigates the impurities in the fuels that can detrimentally impact the capture process & will devise strategies to limit the adverse effects these can have.

In the UK energy supply system of the future, electricity and hydrogen (used to decarbonise transport, space heating and industry) could be two low carbon energy vectors which may be generated in the same location: in low carbon CCS industrial clusters with a common infrastructure. We investigate integration of the process of hydrogen production with electricity generation from the same fuel source, natural gas. The objective is to achieve cost reduction via sharing of subcomponents of the CO₂ capture process and via flexibility to cope with varied demand of both vectors over time.

To drive down the cost of CO₂ capture, it is essential to develop more cost effective technologies than amine scrubbing, which has been adopted from the oil and gas industry. One such technology is solid adsorbents for CO₂ capture. A pilot scale facility for testing will address the key issues concerning scale up, including the thermal and mechanical stability, and moisture sensitivity of the new adsorbents under real process conditions.

Here, we investigate a novel system for CO₂ capture from a gas turbine. The aim is to boost the concentration of CO₂ in the exhaust of the system by partially recycling the gas. We will also investigate the potential for a radically new cycle involving oxygen firing (with recycled CO₂ to keep the temperature down).

Algorithms are being developed to simplify and speed up the computational models used in CCS research. This is done through creating metamodels, which once complete, will be used to analyse how various carbon capture technologies can impact the UK energy system as a whole. Policy makers could also use this as a tool to inform their strategic decisions about how CCS works at a system level.

This work package will investigate the use of CO₂ capture and oxygen carrying materials within Cranfield University’s state-of-the-art pilot plant facilities. These materials will be manufactured at the kilogram scale in collaboration with our partners. We are aiming to study the structural properties of the particles and look at their particle breakage mechanisms when fluidised under realistic operating conditions.

This project will construct detailed models of the applications of the new capture materials being developed in work packages A1 and A2. The models produced will be validated and used to feed back to the experimental work at Imperial College London, Cranfield University and the University of Nottingham, but will be too complex for direct use in system level models. The process models will therefore feed into the development of the reduced order models in AC5.

Injecting CO₂ into the subsurface will cause a temporary increase in the pressure of fluids trapped within the rocks. Understanding how this pressure wave travels through the rocks and the possible effects of increasing pressure in the subsurface are important to ensure the safe containment of the CO₂. To improve our ability to predict the volume of CO₂ which can be stored, we are modelling the propagation of pressure throughout the reservoir. By constructing reduced models to explain this surface ground deformation in current storage sites, we can increase our understanding of the distribution of pressure over time within storage reservoirs.

In planning to inject CO₂ underground it's important to be able to predict where and how quickly CO₂ will move, and where it will be trapped. These predictions are made difficult by a combination of the complexities of fluid dynamics and the unknown and heterogeneous nature of the subsurface rocks in which CO₂ will be stored. To improve our ability to design CO₂ storage projects and estimate the capacity of a formation for CO₂ storage, we're studying key problems at a range of size scales of importance to CO₂ storage. This includes questions such as: How does rock heterogeneity impact the flow pathways of injected CO₂? How quickly does CO₂ dissolve into water in the subsurface? And, what can we measure about rocks in the laboratory that would enable us to answer these questions at the larger scales associated with underground CO₂ plume movement?

Two scoping studies aim to investigate a fit-for-purpose numerical simulator for offshore UK CO₂ stores. Using the correct physics, this research aims to begin a design process to make better software predicting CO₂ saturation and spread.

This work package aims to examine the feasibility of developing a pilot scale CO₂ injection test site in the UK. Many other countries have developed their own CO₂ injection test facilities (eg Germany, Spain, United States, Australia, Canada) and we believe that it would be beneficial for the UK to have its own as well. This would comprise a research facility to test typical UK storage reservoir rocks with experiments focussed on particular uncertainties in UK underground storage, and to develop a core of practical storage expertise in UK scientists. Ideally the research site would be situated in an area where CO₂ is already available from industrial sources and where the potential for future larger scale offshore storage is present.

This work serves as an integrating effort across the three main themes of Capture, Storage, and Systems and Policy. We explore the social, technical, and economic barriers and advantages associated with the large scale deployment of CCS in the UK’s energy system and will provide insight as to how CCS can best be deployed to maximise value to the UK’s economy.

In order to meet the Paris climate target, we need to remove significant amounts of CO₂ from the atmosphere, with bioenergy plus CCS (BECCS) considered a promising option. However, sustainable biomass is a scarce resource, and must be used in the best manner possible. This work will study how biomass can optimally be used to both remove CO₂ from the atmosphere and simultaneously provide renewable energy services.

CCS has been identified as a key element of the UK’s options for reducing its CO₂ emissions. However, progress in bringing the approach to commercial deployment has not matched its potential. This work package will work with key stakeholders (e.g. government, industry, NGOs, lay publics etc.) to better understand the key issues and identify priorities in establishing CCS within the UK energy system, and to help build the necessary foundations to establish a social license to operate CCS in the UK.
