The assessments were carried out by the globally-operating emissions measurements specialist Wöhler Technik GmbH on a prototype of a hydrogen heating system developed by HYTING. The results show show that, unlike conventional combustion-based heaters, HYTING's unique catalytic hydrogen heating system produces only water as a by-product and emits no detectable CO2-, CO- or NOx emissions. The measurements were performed using a mobile exhaust gas analyzer, the Wöhler A 550, which was specially equipped with H₂ analytics for these tests.

Receiving third-party validation of its hydrogen heating system is significant achievement for HYTING, and one which demonstrates the effectiveness of its proprietary technology, and its potential for playing a major role in decarbonising heating of commercial and residential buildings – a challenge that the European Environment Agency recognises as critical1.

Tim Hannig, Founder and Managing Director of HYTING, said: "We greatly appreciate the support and expertise of Wöhler Technik in measuring the quality of our catalytic reaction. Receiving confirmation from Wöhler that our technology operates emissions-free reinforces our development work."

"As a technology-oriented company focused on environmental measurement technology, we're pleased to support the development of innovative solutions in heating technology from the outset and to confirm the safety and reliability of operations through our measurements. The flameless and emissions-free application of hydrogen offers tremendous potential and the opportunity to meaningfully expand the range of sustainable heating solutions." said Dr. Michael Poeplau, CEO of Wöhler GmbH.

The test results highlight the efficacy of HYTING's simple, safe, efficient, and clean method of generating heat directly from hydrogen. The system uses the principle of flameless oxidation to generate heat. In a specially developed catalyst, hydrogen reacts with oxygen from the air, releasing heat. No harmful emissions are produced; water is the only by-product. As no flammable hydrogen concentrations are used at any operating point, it is inherently safe and easy to integrate both as a retrofit solution and into new-builds.

The technology is as robust and cost-effective as it is innovative because it uses many proven, existing components from the heating and automotive industries. It's also modular and highly scalable in design, with outputs of 10-300 kW, enabling it to be configured for a wide range of different applications, including industrial, commercial, and residential buildings, process heat, and commercial vehicle heating systems.

HYTING already has a first customer – Flusys GmbH – with installation and commissioning taking place in early 2025 at Flusys' newly-established production facility for precision pumps in Offenbach, Germany. The 1,000 cubic-meter production space will be heated using hydrogen from a nearby supplier. 

HYTING and Wöhler Technik have decided to continue working together in the future. Wöhler Technik will further support HYTING in the series development of the hydrogen heating system with its measurement technology.

About HYTING:

HYTING is a heating technology company founded in 2021 with the aim to deliver carbon-free heating fuelled by hydrogen: no CO2, NOx, or particulates. It has developed a forced-air heating system (patents-pending) that utilises a molecular, exothermic catalytic reaction to turn a mixture of hydrogen and oxygen from the air into heat – the only by-product is water. This flameless oxidation process is at the heart of HYYTING's simple, safe, efficient and clean heating systems.

Decarbonising heating is a globally recognised challenge, and HYTING's technology can help to accelerate the transition from carbon-fuelled heating technologies to cleaner, more sustainable heating systems, and enabling net zero emissions by 2050.

HYTING's system will initially be used in commercial and industrial applications with heat outputs from 10-300 kW per unit. The company is scaling quickly from prototype to series production, with the first customer trials beginning early 2025. HYTING is based in Wiesbaden, Germany, and is run by a leadership team with decades of experience in the engineering sector.

HYTING about the technology:

We have radically simplified the use of hydrogen by applying the principle of flameless oxidation to generate heat. Our patent-pending technology utilizes a specially developed catalyst where hydrogen and oxygen from the air react to release heat. This allows us to offer CO2-free heating across all performance ranges, even at high heating capacity requirements.

✓ Simple: Our technical design is highly innovative yet not complex. Field-tested and volume-proven components are used in a newly conceived catalytic system which works with commercial-grade hydrogen at low pressures, thus enabling broad utilization.

✓ Safe: The catalytic reaction process works at all operating points with non-flammable hydrogen concentrations below 3%. Proven, series-produced components from the automotive and heating industries offer high reliability, long service life, and inherent safety.

✓ Efficient: By utilizing the enthalpy of vaporization of hydrogen, we achieve a heat output of 114% of its net calorific value. As the heated air is used directly and without a heat exchanger, we generate 37.4 kWh of thermal energy from 1 kg of hydrogen – more than any other hydrogen heating system.

✓ Clean: Our technology does not produce any emissions – neither CO2 nor NOx, nor particulate matter. The only by-product is water. This gives it considerable advantages over conventional hydrogen burner technologies.
