PhD stipend in carbon capture storage impurities and corrosion modeling (14-22105)

At the Faculty of Engineering and Science, AAU Energy, a position as PhD in modeling of impurities and corrosion for carbon capture storage (CCS) is open for appointment from 15-12-2022 or soon hereafter. The position is fixed for 3 years and will be positioned in the Energy Metropolis of Denmark, Esbjerg, at the AAU campus.

Job description

The project is part of the InnoMission call that invests in mission-driven green research and innovation partnerships that will significantly contribute to society's green transformation and the development of sustainable climate technologies for the benefit of Denmark and the rest of the world. The Danish government designates four specific green research and innovation missions that will contribute to the green transition nationally – one of them being the collection and storage or use of CO2 . More information about the InnoMisson call for the collection and storage or use of CO2 can be found here: InnoMission - CCUS

Job description 
CCS is considered to become a key intermediate technology in reducing CO2 emissions, and it would be difficult to achieve the Paris Agreement's 1.5°C pathway target without it. CCS is a vital but temporary solution in sectors that are hard to decarbonize. Thus, it has been agreed upon that CCS will play a big part in the future climate policy in Denmark. The political agreement in Denmark has resulted in a total grant pool for CCS of €2 billion in the coming years. The support will be divided into two parts. The first part of the pool will be implemented in the short term to kick-start the market. Esbjerg will likely play a central role in establishing a CCS industry as the current offshore industry in Denmark is centralized around Esbjerg due to its geographical location close to the North Sea. Besides, CCS is also part of the seven missions at AAU Energy: "Circularity and carbon capture in the energy sector," which emphasizes the department's strategy of keeping strengthening its position in the CCS research domain.
The main challenge is: if, how, and when CCS would become commercially feasible through either high national CO2 taxes, trading CO2 permits, or direct and indirect governmental support. In that context, the transportation method and the determined legislative quality of the CO2 will greatly impact the cost. For CO2 capture and storage deployment, understanding the impact of impurities in the gas or dense phase CO2 stream arising from fossil fuel power plants or other large-scale industrial emitters is of fundamental importance to the safe and economical transportation and storage of the captured CO2. Transportation of CO2 involves a risk of significant releases in case of pipeline rupture, which can endanger the surroundings as CO2 is transported under very high pressure and in large quantities. Therefore, transportation of CO2 to a storage site using high pressure must be governed by safety, environmental and economic considerations. Especially the concentration of impurities, such as O2, H2O, H2S, and NOx, in the CO2 stream can affect the pipes' corrosion rate. 
The overall project is intended to investigate how the infrastructure is affected by CO2 and impurities when transported in the future CCS industry, which is an essential part of the CCS solution but is seldom reviewed. The infrastructure design for transport and storage sites should be resistant to the future-defined CO2 quality and flexible in its design if considering future needs for CO2 in the Power-to-X production of green fuels. Furthermore, the national infrastructure of CO2 should be compatible with international infrastructure to allow future import/export of CO2 if Danish operators should not lose market shares. As part of the InnoMisson call, our overall project (CarbonAdapt) collaborates with several Danish companies: Welltec, Rambøll Danmark A/S, FORCE Technology, and Gas Storage Denmark. Welltec has developed a dedicated test loop facility for corrosion testing in a liquid/supercritical CO2 environment. The test loop facility at Welltec will simulate corrosion conditions similar to those expected in CO2 transportation pipelines and injection wells. In addition, the test loop facility will provide data to study the effect of different impurities of CO2 streams for injection, flow conditions, and reservoir fluids on materials, both on the existing type of wells and for new pipelines. More information about the test loop facility can be found on: Welltec - Test loop facility 
The aim of this PhD position is to utilize the results from the test facility to establish a mathematical model between CO2 impurities and corrosion in wells and pipelines. In addition, the learning in this PhD project will be used to identify requirements for qualifying existing infrastructure for CO2 transport both on a technological level to assist in determining, e.g., estimating the material lifetime, as well as being an important tool on a legislative level to establish a, e.g., gap analysis on a common practice for future CCS applications.
