1. Decarbonizing the Aviation Industry: The Rise of Sustainable Aviation Fuel (SAF)

How can the aviation industry achieve carbon neutrality? Aviation accounts for approximately 2.5% of global energy-related carbon emissions, and Sustainable Aviation Fuel (SAF) is gaining attention as a key solution.

This article explains what SAF is and details various production pathways such as HEFA, FT, ATJ, and PtL. It also highlights the critical role of catalyst technologies in each process and introduces Heesung Catalysts’ hydrogenation catalysts, syngas conversion catalysts, and CO₂ conversion catalyst technologies. Readers can also explore ReFuelEU policy trends and the current status of SAF adoption by airlines, offering a comprehensive view of aviation decarbonization trends.

2. Waste Reimagined : Biogas, the Energy Revolution for Carbon Neutrality

“What if the food waste you throw away today could heat your home tomorrow?”

Biogas is a form of biofuel that provides an effective solution for both waste treatment and clean energy production. This article covers the full value chain — from anaerobic digestion and gas upgrading to applications in city gas supply, power generation, district heating, CNG vehicle fuel, hydrogen production, and green methanol. It also explains how catalyst technologies are applied in key processes such as biogas upgrading, steam methane reforming (SMR), dry reforming of methane (DRM), and methanol synthesis.

3. Key to the Clean Hydrogen Era: Ammonia Cracking Catalyst Technology

As hydrogen production and utilization expand, efficient storage and transportation have become major challenges. Ammonia (NH₃) is gaining attention as an alternative carrier because it remains stable as a liquid under mild conditions and offers high hydrogen storage density. The efficiency of the cracking process that converts ammonia back into hydrogen is the critical factor.

Heesung Catalysts has developed both low-temperature ruthenium (Ru)-based catalysts and high-temperature nickel (Ni)-based catalysts optimized for different operating environments. Research achievements improving ammonia cracking efficiency through nanostructure control, surface modification, and promoter technologies received a Best Paper Award at the 2023 KHNE (Korean Hydrogen and New Energy Society) Fall Conference.

4. Catalyst Q&A Series – Part 1. Why Are Catalysts Important?

Part 1 of the Catalyst Q&A Series, which answers the most fundamental and important questions about catalysts, also drew strong interest. The article explains the definition and operating principles of catalysts, their role in chemical reactions, and the concept of activation energy in an accessible way.

It includes practical examples such as automotive three-way catalysts (TWC), differences between metal and non-metal catalysts, and precious metal catalyst recycling. It also discusses what challenges arise without catalysts in industrial processes and how catalysts impact productivity and environmental efficiency.
