SOE ECE WPB3a - Högtemperatur och askforskning

Forskningsprojekt, 2022 –

This project is targeting increased electricity production from green fuels in combination with the implementation of CCS-technologies, i.e., BECCS. The current efforts in society towards BECCS in combustion units is primarily based on post-combustion techniques, with an inherent energy penalty leading to greatly decreased power production when CO2 is captured. Oxyfuel (with the possibility to utilize cheap oxygen from hydrogen production units) and CLC (Chemical Looping Combustion) does not have this inherent energy penalty, as the CO2 is separated during combustion, rather than post combustion. By integrating several research disciplines, these combustion techniques can be developed and optimized, and thereby play an important part of the future energy system, not only producing heat and power but also achieving large scale CO2 capturing from renewable sources, enabling negative CO2 emissions. We focus our research on enabling these new techniques. This is done by addressing the following topics/areas:

• Increase the in-depth knowledge about the events leading to corrosion so that the  lifetime of various alloys to be used as heat exchangers can be predicted (e.g., superheaters) in oxyfuel and CLC power plants.
• Develop AI-based interpretation of microscopy images of corroded samples in order to both broaden the analytical capacity and remove potential bias but also to lay the foundation for AI-based lifetime prediction models. In connection to this, new instrumentation at CMAL (BIB) will be optimized for producing high quality cross sections to be used for SEM/EDX/EBSD and subsequently AI.
• Further strengthen the collaboration between different fields within the ECE profile. BECCS engages several researchers on Chalmers and ECE involves several of them. Thus, we will continue to increase the efforts to seek out new collaborations between the fields as well as work towards receiving external grants which involves several ECE fields. The WP3b field collaborates primarily with WP B2, WP B3b and WP B8.
• Work towards broadening the scope of the High Temperature Corrosion center by inviting and share the HTC network such as seminars, conference and course (targeting Ph. D. students) about high temperature corrosion to the ECE community.
