Catalyst solutions that enhance the environmental performance of power systems\u2014from hydrogen supply to emissions control<\/strong><\/strong><\/h4>\n\n\n\n
<\/div>\n\n\n\n

With the launch of Korea\u2019s 2026 Hydrogen Power Generation Bidding Market, now divided into Clean Hydrogen Power<\/strong> and General Hydrogen Power<\/strong>, the power industry is accelerating the demonstration and commercialization of hydrogen- and ammonia-based clean fuel technologies.<\/p>\n\n\n\n

While clean hydrogen power offers significant potential for reducing carbon dioxide (CO\u2082) emissions, commercial deployment requires more than low-carbon fuels alone. Stable hydrogen supply, optimized combustion conditions, power generation efficiency, and effective emissions control must all work together to ensure reliable system performance.<\/p>\n\n\n\n

Ammonia has emerged as a promising hydrogen carrier because it can be liquefied at approximately -33\u00b0C under atmospheric pressure<\/strong>, making it easier to store and transport than hydrogen. However, when integrated into power generation systems, unreacted ammonia (ammonia slip) must be carefully controlled. In addition, high-temperature hydrogen combustion can generate nitrogen oxides (NOx), making both NOx and ammonia slip critical factors in maintaining the environmental performance of hydrogen power plants.<\/p>\n\n\n\n

As a result, exhaust gas aftertreatment catalyst technologies are becoming increasingly important in hydrogen power generation.<\/p>\n\n\n\n

Key Catalyst Technologies for Clean Hydrogen Power<\/strong><\/strong><\/strong><\/h3>\n\n\n\n

Clean hydrogen power generates electricity using clean hydrogen or hydrogen carriers such as ammonia. In practice, reliable operation depends on the seamless integration of multiple technologies\u2014from hydrogen production and supply to power generation and emissions control.<\/p>\n\n\n\n

Why NOx Control Matters in Hydrogen Power Generation<\/strong><\/strong><\/strong><\/h3>\n\n\n\n

Nitrogen oxides (NOx) are among the primary air pollutants that must be controlled in power plants and industrial facilities.<\/p>\n\n\n\n

Although hydrogen contains no carbon and therefore produces no CO\u2082 during combustion, NOx can still form under certain operating conditions when hydrogen is burned with air at high temperatures.<\/p>\n\n\n\n

Because hydrogen combustion produces a very high flame temperature, thermal NOx formation through the oxidation of atmospheric nitrogen must be considered. When ammonia is used as a hydrogen carrier, nitrogen contained in the fuel introduces additional pathways for NOx formation, making emissions control even more complex.<\/p>\n\n\n\n

For this reason, clean hydrogen power requires effective NOx reduction technologies in addition to carbon reduction strategies.<\/p>\n\n\n\n

SCR Catalysts: A Proven Solution for NOx Reduction<\/strong><\/strong><\/strong><\/strong><\/h3>\n\n\n\n

Selective Catalytic Reduction (SCR) is one of the most widely used exhaust gas aftertreatment technologies for converting NOx into harmless nitrogen and water. It has been extensively applied in power plants, industrial boilers, and marine engines, and is now being evaluated as a key emissions control technology for hydrogen- and ammonia-fueled power systems.<\/p>\n\n\n\n

Since operating temperatures and exhaust gas compositions vary widely among power generation facilities, SCR catalyst selection must be optimized for each application.<\/p>\n\n\n\n
