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
