Abstract

The global shift toward sustainability and the urgent need to reduce reliance on fossil fuels have intensified research into alternative energy carriers across transportation and power generation sectors. Gas turbines and microturbines, known for their high efficiency and operational flexibility, offer a promising platform for integrating low-carbon fuels into electricity production.This study presents the design of an experimental microturbine developed to examine the combustion characteristics of sustainable gaseous fuels–specifically hydrogen and biogas–under controlled laboratory conditions. The investigation focuses on fuel applicability, combustion stability, and emission profiles, contributing to developingcleaner and more sustainable energy conversion systems.The microturbine is constructed using a commercially available automotive turbocharger, featuring a centrifugal compressor and a centripetal turbine, paired with a custom-designed counterflow combustion chamber. Component selection and chamber design are guided by engineering calculations and a thorough literature review, ensuring mechanical compatibility and experimental reliability. The setup provides a scalable and accessible platform for advancing sustainable combustion technologies.
