Hydrogen heating technology company HYTING has commissioned its second customer installation, deploying two air-heating units delivering a combined heat output of 80 kW (2 x 40 kW) at a production facility in Markkleeberg, in the German state of Saxony. This represents a significant step forward in the company’s commercial rollout, with capacity eight times higher than in HYTING's first installation. It also marks the customer debut of HYTING’s 50 kW heat generator platform, which features a 10:1 turndown ratio for continuous modulated heat output.

The facility in Markkleeberg is shared by two companies: BURO GmbH, which uses it to manufacture sheet-metal components on laser cutting and punching systems, and Südmetall Schließsysteme GmbH, which assembles electronic locking systems. Each of the two HYTING air-heating units serves one of these production areas, enabling tailored temperature distribution throughout the building.

The system operates in a hybrid configuration alongside a heat pump. The heat pump manages the base heating load, while HYTING's units cover peak demand during periods of high heat requirement or low ambient temperatures. This strategy significantly reduces grid connection capacity and demand charges – in this case by 70% – and enables smaller sizing of the heat pump, reducing both capital expenditure and operating costs, as the heat pump runs continuously at its optimal operating point. Customers can reduce operating costs from day one and achieve a return on investment within approximately three years.

In the first phase of the installation, hydrogen is sourced from a nearby supplier. However, a further milestone is planned for later this year when BURO's subsidiary H2 Green Planet GmbH – which develops and manufactures electrolyzers for the production of green hydrogen – intends to install an on-site electrolyzer. This would make the site one of the first commercial buildings to generate and consume its own green hydrogen for heating, at a target production cost of €4-6/kg.

Tim Hannig, Founder and CEO of HYTING, said, “Our second installation marks a significant step up for us, in terms of scale and as proof-of-concept of what hydrogen air-heating can do for commercial and industrial buildings. At 80 kW, this is not only our most powerful installation so far, but it also demonstrates the effectiveness of our modular design by delivering that total heating capacity with two units. And with H2 Green Planet planning to bring onsite hydrogen production to the facility later this year, we are seeing the full picture coming together: clean heating, powered by locally produced green hydrogen, with a compelling business case from day one.”

“As a company with more than 50 years of engineering expertise, we know that the clean energy transition will only succeed if it’s affordable and cost-efficient. HYTING's technology shows that it’s already possible today by covering our peak heating demand without adding to our electricity load or our carbon footprint. And through H2 Green Planet, we are taking the next logical step: producing our own green hydrogen on site. This is what a practical, commercially-grounded approach to decarbonization looks like,” said Jürgen Burger, CEO, BURO.

The Markkleeberg installation follows another milestone for HYTING, with its 50-kW heat generator receiving Gas Appliance Regulation (GAR) certification. GAR-certification is mandatory and must be issued by an independent accredited laboratory: HYTING once again chose Kiwa to perform the stringent evaluation and subsequent approval of its technology. Kiwa is one of the sector’s longest-established test houses, has a worldwide network of laboratories, and also performed the GAR-certification of the 10-kW heat generator.

Additionally, HYTING has proven the exceptional reliability of its technology by successfully passing 2,500 hours of durability testing conducted by one of the world’s leading engineering service providers. The test simulated the thermal loading imposed by 10 years of normal operation, and was completed without any problems or failures, or any wear to safety-critical components. This ably demonstrates how effectively HYTING’s technology can supersede incumbent fossil fuel heating systems.

HYTING's technology is based on a proprietary flameless catalytic process in which hydrogen reacts with oxygen from ambient air to generate heat. There are no CO2, NOx, or particulate emissions – the only by-product is water vapor. The technology does not use flammable concentrations of hydrogen at any operating point, making it inherently safe. Its compact, modular design means units can be combined to meet higher heating demands, and the technology is suitable for both new installations and retrofits.

The urgency of decarbonizing commercial and industrial heating has never been greater. European Commission figures show that buildings account for 40% of all energy consumed in the EU and 36% of its greenhouse gas emissions, with heating accounting for a large proportion of that. Yet despite this, the EU Buildings Climate Tracker finds that the sector is more than 40% behind the pace of decarbonization required to meet 2030 climate targets.

The EU's Hydrogen Strategy explicitly identifies heating in commercial and residential buildings as a key application for hydrogen infrastructure, and recognizes that for many buildings, hydrogen offers a viable and complementary pathway alongside electrification to replace fossil fuels.

The broader hydrogen market is growing rapidly, providing an encouraging backdrop for technologies such as HYTING's. The International Energy Agency’s Global Hydrogen Review 2025 report shows that worldwide hydrogen demand reached almost 100 million tons in 2024 – and that low-emissions hydrogen production is set to increase more than fivefold by 2030 compared to 2024 levels, as committed projects come online. As costs continue to fall and infrastructure develops, the expanding supply of blue and green hydrogen will make it increasingly accessible to commercial and industrial building operators – strengthening and supporting the wider rollout of HYTING’s heating technology.
