In the relentless pursuit of sustainable energy solutions, hydrogen combustion in gas turbines represents a revolutionary leap forward. Hanwha Impact and Hanwha Power Systems' latest achievement in operating a medium-to-large-scale gas turbine entirely on hydrogen fuel marks a defining moment in the energy sector. This groundbreaking development heralds a new era of clean energy technology.
A Historical Milestone:
December 20 stands out as a significant date in the energy industry's calendar, as Hanwha announced their success in achieving full hydrogen combustion in an 80 MW gas turbine. This achievement is not an isolated event but follows a series of pioneering efforts, including a world-first demonstration of 60% hydrogen blending in April 2023. The progression from 60% to 100% hydrogen mixing ratio is not just a numerical increase but a substantial advancement in clean energy technology.
The Triumph of Full Hydrogen Combustion:
The concept of "full hydrogen combustion" implies the complete replacement of LNG with hydrogen as the sole fuel source for power generation. This transition is critical in the context of environmental conservation. During the initial 60% blending tests, a 22% reduction in CO2 emissions was observed. However, with full hydrogen combustion, Hanwha has achieved what many thought was near-impossible—virtually zero carbon dioxide emissions during operation, with a CO2 concentration in the emissions of a mere 0.04%.
Furthermore, the nitrogen oxide emissions—a notorious byproduct of hydrogen combustion—were kept below 9 ppm, eliminating the need for additional reduction devices. This demonstrates Hanwha's proficiency in managing the high flame temperature of hydrogen to ensure low-pollution combustion.

Economic and Environmental Synergy:
Hanwha's hydrogen turbine technology is not only a triumph for environmental advocates but also represents a significant economic opportunity. By applying this technology to extend the life of aging LNG turbines, Hanwha is effectively doubling the economic benefits. This approach not only mitigates the financial burden of replacing outdated infrastructure but also contributes to the revitalization of existing power facilities.
Towards a Carbon-Free Future:
The world is in a critical transition towards sustainable energy practices, and Hanwha's achievements provide a beacon of hope. The success of full hydrogen combustion in gas turbines paves the way for a future where clean, efficient, and economically viable energy solutions are the norm.
In conclusion, The dedication of Hanwha to environmental responsibility places them at the forefront of the clean energy revolution. As we confront the challenges of climate change and the global imperative for sustainable energy, Hanwha's innovation in hydrogen combustion technology offers a promising glimpse into a brighter, cleaner future for all.
