In a rapidly evolving energy landscape, the role of Micro Gas Turbines (MGTs) is coming into sharper focus as researchers explore their potential to bridge the gap between traditional energy technologies and the urgent need for low-carbon solutions. A recent study published in the journal ‘Energies’ highlights the challenges and opportunities that MGTs face in achieving commercialization comparable to that of Internal Combustion Engines (ICEs) and renewable energy sources (RESs).
Lead author A. H. Samitha Weerakoon from the Faculty of Science and Technology at the University of Stavanger emphasizes the importance of understanding techno-economic assessments (TEA) in advancing MGT technology. “MGTs have the potential to be game-changers in the energy sector, but they have not yet achieved the level of market penetration seen with ICEs and RESs,” Weerakoon explains. “The lack of comprehensive TEA activities has stymied their growth, and it’s crucial that we address this gap to harness their full potential.”
MGTs are lauded for their fuel flexibility, efficiency, and ability to integrate with renewable sources, making them ideal candidates for distributed energy generation systems and microgrids. However, the study reveals that MGTs currently face significant economic hurdles, including high capital expenditures and lower learning rates compared to their ICE counterparts. The levelized cost of energy (LCoE) for MGTs remains uncompetitive, ranging from USD 0.0417/kWh to USD 0.356/kWh, a stark contrast to the more favorable economics of ICEs and RESs.
The research points to a promising avenue: hybrid systems that combine MGTs with RESs could lead to substantial cost reductions. For instance, the study notes that with strategic investments and policy support, MGTs could reduce their LCoE by up to 40%. This could position them as a more viable option in the competitive energy market, especially as the global demand for sustainable energy solutions continues to rise.
Weerakoon’s findings underscore the necessity for targeted research and development investments to refine TEA methodologies for MGTs. “Without a strategic increase in TEA activities, MGTs may struggle to achieve the technological and economic maturity needed to compete effectively,” he warns.
As the world strives for carbon neutrality, the integration of MGTs could play a pivotal role in supporting the transition to cleaner energy systems. The research advocates for a comprehensive approach to TEA that leverages the successful methodologies established in the ICE and RES sectors. By doing so, stakeholders can better predict cost trajectories and make informed investment decisions, potentially unlocking a significant market for MGTs.
The implications of this study extend beyond academia; they resonate with industry stakeholders looking to invest in sustainable technologies. As Weerakoon aptly puts it, “The future of MGTs in the energy sector hinges on our ability to adapt and innovate, ensuring they are not just a theoretical solution but a practical one that can meet the energy demands of tomorrow.”

Researchers and industry professionals alike will be keenly watching how MGT technology evolves in the coming years, as it holds the promise of a cleaner, more efficient energy future.
