Key Takeaways
1. The trial at Plant McDonough-Atkinson achieved a 22% reduction in CO₂ emissions using a 50% hydrogen and natural gas mix, compared to a previous 10% reduction with a 20% hydrogen mix.
2. The test did not negatively impact nitrogen oxide (NOx) emissions, addressing a key challenge in hydrogen combustion.
3. Georgia Power and Mitsubishi Power’s findings provide a model for global power producers to reduce carbon emissions while maintaining natural gas facilities.
4. Georgia Power has reduced its carbon emissions by over 60% since 2007, highlighting significant progress in emission reduction efforts.
5. Mitsubishi Power’s advanced combustor technology enables stable operation with higher hydrogen blends, though independent verification of the test results is still pending.
The experiment carried out at Plant McDonough-Atkinson located in Smyrna, Georgia, marks an important milestone in adapting current power systems for a future with lower emissions. The findings were disclosed yesterday, June 16, 2025.
Significant Emission Reductions
The trial involving the Mitsubishi M501GAC turbine utilized a mix comprising 50% hydrogen at both partial and full capacity, achieving a notable 22% decrease in CO₂ emissions when compared to using natural gas alone. This builds upon a previous test from 2022 that utilized a 20% hydrogen mix, resulting in a 10% reduction in CO₂ emissions. Importantly, the recent test did not adversely affect nitrogen oxide (NOx) emissions, which is a major technical hurdle in hydrogen combustion.
A Model for the Future
By demonstrating the feasibility of a 50% hydrogen blend, Georgia Power and Mitsubishi Power are offering a model for power producers around the globe, indicating that it is indeed feasible to significantly lessen carbon emissions without needing to shut down natural gas facilities.
“We have successfully achieved a 50% hydrogen blend in an advanced-class gas turbine, highlighting the potential of our cutting-edge technology,” stated Mark Bissonnette, executive vice president and chief operating officer at Mitsubishi Power Americas.
Progress in Emission Reduction
Georgia Power, a subsidiary of Southern Company, has reportedly reduced its carbon emissions by more than 60% since 2007, thanks to such groundbreaking advancements.
The latest test results are compared to the 2022 findings as follows:
The trial employed Mitsubishi Power’s advanced combustor technology, allowing for stable functioning with increased hydrogen blends. There has been no independent verification of this test as of yet.
The Anker PowerHouse 767 power station (currently priced at $1,199 on Amazon) is designed to work with solar panels, presenting an opportunity to be part of the renewable energy shift.
