Nationwide Boiler Announces Hydrogen Firing Capabilities for Existing Fleet of Rental Boilers

**Fremont, CA, December 2, 2022** NATIONWIDE BOILER INC. ANNOUNCES HYDROGEN FUEL CAPABILITY FOR EXISTING RENTAL BOILERS Nationwide Boiler Inc., a pioneer in the boiler rental industry with over a hundred units in its fleet, has made a groundbreaking announcement regarding its ability to utilize hydrogen as a fuel source for its current fleet of package watertube rental boilers. As global concerns over climate change and decarbonization continue to grow, this move aligns perfectly with Nationwide Boiler's commitment to fostering a sustainable future for both the company and the broader boiler industry. Larry Day, President & CEO of Nationwide Boiler, expressed pride in the company's legacy of innovation. "Back in the 1990s, Nationwide Boiler was the first rental boiler company to transition our entire watertube boiler fleet to 30 ppm low NOx technology. That same decade, we foresaw the need to push further toward cleaner operations, leading to the creation of our CataStak™ SCR System for achieving single-digit NOx emissions," he noted. "With the world moving toward carbon neutrality, the ability to operate on hydrogen-blend fuels is crucial. It allows us to provide customers with the flexibility they need to advance their own decarbonization efforts." While hydrogen combustion differs significantly from natural gas, Nationwide Boiler's engineering team has extensive data and experience supporting the use of hydrogen-blend fuels in package boiler applications. Thanks to the company's rigorous standards for rental boiler construction—incorporating high-grade valves, robust fuel trains, advanced burners, and other critical components—the modifications needed for hydrogen firing are minimal. The company has verified that its current fleet of watertube rental boilers, ranging from 30,000 to 125,000 pounds per hour (pph), can safely fire blends of up to 20% hydrogen mixed with natural gas without requiring any system adjustments. For higher hydrogen concentrations, further evaluation of specific components will be necessary, along with potential burner modifications. David Spain, Nationwide Boiler's Technical Manager, emphasized the environmental benefits of hydrogen. "Hydrogen combustion produces no CO2 emissions and is cleaner than petroleum-based fuels. However, it does lead to higher flame temperatures, which can increase NOx output. Fortunately, our CataStak™ SCR system is a proven solution that effectively mitigates this issue, ensuring emissions as low as 2½ ppm NOx." Nationwide Boiler provides not only CataStak SCR systems but also ultra-low NOx 5 ppm firetube boilers and zero-emission electric boiler packages, catering to both temporary rental needs and permanent installations. Since its founding in 1967, Nationwide Boiler has delivered dependable boiler solutions to industrial clients around the globe. Its comprehensive offerings include temporary and permanent boilers with low and ultra-low NOx emissions, along with a variety of auxiliary equipment. Nationwide Boiler's CataStak™ SCR system, installed in over 200 locations, stands as a reliable and proven method for meeting ultra-low NOx emission regulations. Headquartered in Fremont, California, Nationwide Boiler maintains a storage and maintenance facility in Alvin, Texas, and a control panel fabrication facility in Washougal, Washington.
