Patibandla, Akul Sai (author)There is an increase in the amount of CO2 emissions in the past few decades and the process of capturing it back is at a much lower rate. The need of the hour is to reduce the emission rate or even avoid producing them in certain aspects. There is a transition towards renewable energy sources<br/>that could help us maintain the balance required....master thesis 2023

Stroo, Aike (author)Methane pyrolysis is a technology that has the potential to greatly reduce the CO2 emissions of hydrogen production on a large scale. The process generates solid carbon instead of gaseous, thereby inhibiting emissions and has a relatively low process energy demand.<br/><br/>A three-step approach was taken to investigate the feasibility of...master thesis 2023
