McDonough, GA – June 20, 2025 – In a landmark achievement for clean energy, Georgia Power and Mitsubishi Power Americas have announced the successful completion of a pioneering test program, achieving a record-setting 22% reduction in carbon dioxide (CO₂) emissions at an operational natural gas power plant. The breakthrough came through the seamless blending of hydrogen with natural gas at Georgia Power's Plant McDonough-Atkinson, marking a significant leap forward in decarbonizing existing power infrastructure.
The collaborative project, culminating in rigorous testing over several months, demonstrated the viability of using hydrogen – a clean-burning fuel producing only water vapor when consumed – to significantly lower the carbon footprint of electricity generation. The teams successfully integrated hydrogen into the plant's fuel supply, feeding it to a state-of-the-art M501G gas turbine supplied by Mitsubishi Power.
The Key to Success: 50% Hydrogen Blend
The centerpiece of the achievement was reaching and maintaining a 50% hydrogen fuel blend by volume during extended operation. This high blend ratio is substantially beyond previous large-scale demonstrations and validates the technology's potential for deep, near-term emissions cuts.
"Reaching a 50% hydrogen blend reliably in a commercial turbine operating in the field is a game-changer," stated Mark Bissonnette, President & CEO of Mitsubishi Power Americas. "This project proves that hydrogen blending isn't just a laboratory concept; it's a practical, scalable solution available now to help utilities reduce emissions from their existing fleet while maintaining grid reliability. The 22% CO₂ reduction directly measured is a powerful testament to that."
Overcoming Challenges, Ensuring Safety
Integrating hydrogen into existing natural gas infrastructure presented complex engineering challenges. Hydrogen burns differently than natural gas, requiring precise adjustments to combustion systems and advanced control technologies. Safety, naturally, was paramount throughout the testing phase.
"Safety is ingrained in everything we do," emphasized Kim Greene, Chairman, President & CEO of Georgia Power. "Successfully navigating this test at Plant McDonough-Atkinson required meticulous planning, cutting-edge technology from our partners at Mitsubishi Power, and the unwavering dedication of our skilled workforce. This 22% emissions reduction is a major win for Georgia, our customers who expect cleaner energy, and the broader industry. It provides a tangible pathway to reduce emissions from our natural gas units as we continue adding significant renewable resources."
Critical to the safe handling and monitoring throughout the test phase was specialized hydrogen detection and safety equipment. Teams utilized advanced sensors and protocols, including equipment readily available for industrial gas applications like this industry-standard hydrogen safety kit, ensuring operations met the highest safety standards.
Scaling Up the Solution
The success at Plant McDonough-Atkinson is more than a single-plant achievement; it's a blueprint for the future. Both companies emphasize that hydrogen blending technology can be deployed across existing natural gas power plants globally, offering a crucial tool for utilities and governments striving to meet aggressive decarbonization targets.
Looking Ahead: Towards 100% Hydrogen?
While the 50% blend marks a massive step, the ambition doesn't stop there. Both Georgia Power and Mitsubishi Power view this as a stepping stone. Mitsubishi Power's turbine technology is already designed to potentially operate on 100% hydrogen in the future, contingent on the scaling up of affordable, clean hydrogen production and the necessary infrastructure.
