Supporting a Hydrogen Future with the CataStak™ SCR System
As industries move toward a cleaner and more sustainable future, hydrogen is increasingly recognized as a leading solution for reducing carbon emissions. In fact, Nationwide Boiler’s current fleet of package watertube rental boilers can fire up to 20% hydrogen-blended fuels without modifications. However, hydrogen-fired combustion presents a unique challenge—higher nitrogen oxide (NOx) emissions, which contributes to air pollution, ground level ozone and smog formation. Fortunately, Nationwide Boiler’s CataStak™ Selective Catalytic Reduction (SCR) system is a proven solution that effectively reduces NOx emissions in both fossil fuel and hydrogen-fired applications.
The Challenge of Hydrogen Combustion: Increased NOx Emissions
One of the most significant contributors to climate change is carbon emissions and, unlike traditional fossil fuels, hydrogen contains no carbon. While hydrogen provides a carbon-free energy source, its combustion characteristics result in higher flame temperatures than natural gas. These elevated temperatures lead to increased thermal NOx formation, making it difficult to meet increasingly stringent air quality regulations. As regulatory agencies continue to tighten emissions standards, effective NOx reduction technologies are essential to unlocking hydrogen’s full potential as a clean fuel.
The CataStak™ SCR Solution: Near-Zero NOx Emissions
Nationwide Boiler’s CataStak™ SCR system is a proven solution for NOx reduction and has been used in a board variety of fuel fired applications. The CataStak SCR utilizes catalyst and a precise reagent injection process to create a catalytic reaction that reduces NOx emissions, enabling compliance with the most stringent air quality regulations within the US. When applied to hydrogen-fired boilers and combustion systems, the CataStak SCR can achieve near-zero NOx emissions, supporting a truly clean energy future.
Key Benefits of the CataStak™ SCR System for Hydrogen Applications:
- Near-Zero NOx Emissions: Reduces NOx to levels compliant with the strictest air quality standards.
- Proven Technology: Successfully applied in hydrogen, natural gas, and alternative fuel applications with more than 250 installations.
