Testing Programme for Hydrogen Tolerance Tests of Domestic and Commercial Natural Gas Appliances


The THyGA project (‘Testing Hydrogen admixture for Gas Applications’) focusses on technical aspects and the regulatory framework concerning the potential operation of domestic and commercial end-user appliances with hydrogen / natural gas blends.
The core of the project is a broad experimental campaign with the aim to conduct up to 100 hydrogen tolerance tests. In addition, the technical status quo and present knowledge about hydrogen impact on domestic and commercial appliances are assessed and potential future developments of rules and standards are discussed. Also, mitigation strategies for coping with high levels of hydrogen admixture will be developed. By this broad approach, the project aims at investigating which levels of hydrogen blending impact the various appliance technologies and to which extent in order to identify the regime in which a safe, efficient, and low-polluting operation is possible.
The series of public reports by the THyGA project starts with several publications from work package 2, which sets the basis for the upcoming results and discussion of the experimental campaign as well as mitigation and standardisation topics.
This report D2.5 completes the series of public reports from work package 2. It explains the steps of development of the test programme for gas-fired appliance tests with hydrogen admixture and especially describes the exchange between the THyGA partners and the external stakeholders.
The report also explains the process of acquisition of appliances to test and method of selecting appliances.
