Planned Impact
The strategic vision is to develop a world-leading Centre for Industrial Doctoral Training focussed on delivering research leaders and next generation innovators with broad economic, societal and contextual awareness, having strong technical skills and the capability of operating in multi-disciplinary teams covering a range of knowledge transfer, deployment and policy roles.
The immediate beneficiaries of our activities will be the students we train and their sponsoring companies. These students are expected to progress to research/development careers in industry or academia and be future leaders. They will be able to contribute to stimulating UK-based industry into developing the next generation of technologies to reduce CO2 emissions from burning fossil fuels and ultimately improve the UK's position in the global economy through increased jobs and exports.
Other beneficiaries include the industrial and academic partners of the CDT, the broader scientific and industrial carbon capture and storage and cleaner fossil energy communities, skills base and society in general. The key application areas addressed by the CDT will impact on the major technical challenges in the sector over the next 10-20 years as identified by our industrial partners:
(i) Implementing new, more flexible and efficient fossil fuel power plant to meet peak demand as recognised by electricity market reform incentives in the Energy Bill.
(ii) Deployment of CCS at commercial scale for near zero emission power plant and development of cost reduction technologies
(iii) Maximising the potential of unconventional gas, including shale gas and underground coal gasification.
(iv) Development of technologies for vastly reduced CO2 emissions in other industrial sectors: iron and steel making, cement, refineries, domestic fuels and small scale diesel power generators.
These areas also cover biomass firing in conventional plant defined in the Bioenergy Priority Area where specific issues concern erosion, corrosion, slagging, fouling and the overall supply chain economics.
Technically, the students we train will graduate with specialised knowledge in CCS and cleaner fossil energy. This will be underpinned by a broad technical knowledge of the sector and a wider appreciation of the role carbon capture and storage and cleaner fossil energy can play in the UK and internationally. We will also support development of their professional skills including developing their creative thinking skills providing them with a solid foundation to rapidly progress to become the future leaders of innovation and growth in UK industry and academia.
In the short-term, the trained reseachers will apply their knowledge and skills to underpin applications-led activities at the partnering industrial organisations and participate in further academic-industry collaborations. In the longer term, they will progress to lead in the integration of dramatically enhanced carbon capture and storage and cleaner fossil energy technologies that will be of direct benefit across the UK fossil fuel industry and supply chain, leading directly to wealth creation with job protection and growth.
A company sponsoring a student will help define the research they undertake and will be of direct interest to the company. Further, the company will have had long term access to a potential employee. Timely application of the technologies developed will enable and accelerate the development and adoption of CCS and cleaner fossil energy knowledge bringing environmental benefits to the UK and internationally.
The publicity generated by the project will raise public awareness of the role of CCS and cleaner fossil energy igenerally in society. Ultimately the broader benefits to society will include improvements to the quality of life derived from the improved efficiency, flexibility and reliability of the technologies.

| Description | My research is mainly focus on finding the different behaviours of hydro-char production through hydrothermal carbonisation (HTC) process using cellulose and cotton cloth. At the first stage of my research, I found that the energy required for cotton clothes to carbonise is higher than cellulose due to the chemical added to cotton clothes to increase their heat resistance. During the second stage, I researched on the liquid water from HTC and found out that they can be used as a catalyst for future HTC runs. Therefore, I have done further research on how can recycling the process water can reduce the energy and flash water for HTC, but the improvement of energy density is less than the mass. After that, I focused part of my research on studying the product from HTC of clothing wastes for the third stage. My discovery was that the raw material of polyester was also produced during the HTC process. Therefore, how to improve the purity to the level for polyester reproduction became the next target to be studied. During this stage of the research, I found the purity can be improved by pre-treatment before adsorption. |
| Exploitation Route | During my research, I am not only focus on clothing waste, I did some test for different wastes which can also be used for hydrothermal carbonisation (HTC). This can improve the database for HTC which can help both academic and industrial research. HTC research is a way to reduce the greenhouse gas emission as well as improving the resource of solid fuels for power generating and heating. The other part of my research is about recycling polyester clothing. This also can help to reduce the polyester clothing waste and PET bottle waste produce in the future. |
