Flameless Hydrogen Heating Debuts at German Factory

HYTING’s catalytic unit cuts emissions and avoids grid overloads

Posted

A new installation in Offenbach, Germany, offers a quiet but meaningful shift in how industrial buildings might handle peak heating demands. At the Flusys precision pump facility, HYTING has deployed a 10-kilowatt catalytic hydrogen air heater—marking the first time its technology is operating outside the lab.

The hydrogen heater is paired with a conventional electric heat pump to manage space heating across a 1,000-cubic-meter production area. The approach is simple: the heat pump handles everyday demand, while the hydrogen unit activates only during peak periods or cold snaps. That balance allows the system to avoid the need for oversized electrical infrastructure, keeping upfront costs and grid demand charges in check.

This hybrid model is designed to tackle one of the more persistent issues in industrial decarbonization: short-duration heating spikes that drive disproportionate investment in electrical capacity. By deploying hydrogen specifically for those moments—rather than as a full system replacement—HYTING aims to improve the return on investment compared to fully electric systems that may require costly grid upgrades.

For Flusys, a company already experienced in handling hydrogen, the move is pragmatic. It’s a test case for cutting fossil fuel use in heating without adding combustion-related emissions, complexity, or high operational costs. For HYTING, it’s the first step toward validating a modular, real-world alternative to traditional gas-based systems.

A Flameless Path for Industrial Heat

What sets HYTING’s system apart is its use of catalytic hydrogen heating, a process that generates heat through a chemical reaction rather than combustion. Ambient air mixes with hydrogen in a proprietary catalyst, releasing high-temperature air without flames, carbon dioxide, NOₓ, or particulate emissions. The only by-product is water vapor.

The technology is already certified under the EU Gas Appliance Regulation and recently completed a 2,500-hour durability trial simulating a decade of industrial use. Its design is modular, allowing multiple 10- or 50-kilowatt units to be combined for larger facilities or process heat applications up to 300°C.

Unlike full electrification strategies that often hit bottlenecks with grid capacity, HYTING’s system is intended to be flexible. It can integrate with other heat sources—including waste heat—and is well-suited to retrofits where space and electrical capacity are limited. For site managers and energy planners, that opens up new pathways to decarbonize without disruptive infrastructure changes.

With another installation planned for Q1 2026, HYTING is moving from one-off trials toward scalable deployments. The broader pitch is that hydrogen, when used selectively, can complement electrification—not replace it—by filling in the gaps where electricity is either unavailable, inefficient, or too expensive to scale.
