The present work is concerned with the evaluation of the tightness of the components located on domestic and commercial gas lines from the gas meter to the end user appliance, in presence of a mixture 40%H2+60%CH4 at 35 mbar. The components were taken from installations being used currently in Germany, Denmark, Belgium and France. The …

The main goal of THyGA’s WP5 is to investigate ways to adapt residential or commercial appliances that have safety or performance issues, to different levels of H2 concentrations in natural gas. This first deliverable presents some possible mitigation measures based on a literature study and some calculations. Acting on gas quality, to avoid that hydrogen …

This report is the very first version of the document that will present the THyGA short-term test. These tests are carried out to observe how appliances react in the short term (few minutes to few hours) on different H2NG mixtures and long-term test are observing behaviour over several weeks. The analysis is based on the …

Long-term test will be carried out to observe possible appliances alterations (performances or physical alteration) in the long-term (few month) with given H2NG blend. The idea with the long-term testing is to simulate a real situation in accelerating the testing time, several indicators will also be continuously monitored to identify possible alterations. The long-term tests …

This 2nd deliverable from WP4 gives an overview of relevant existing certification experience, on-going standardization activities and field trials in the European Union and other countries, regarding gas appliances using H2NG. It gives a picture of the today’s situation as many of the identified initiatives are ongoing and progressing continuously. This document includes many contributions …

Climate change is one of today’s most pressing global challenges and demands for a phase-out of fossil fuels such as natural gas. One of the most promising substitutes is hydrogen. The carbon-free fuel gas may be produced e.g. from water and renewable electricity. As a gaseous fuel, it can be transported, stored, and utilised in …

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 …

This 3rd deliverable from work package 2 is organised in the following way the first part introduces the basics of various gas combustion technologies and their implementation in domestic and small-scale commercial appliances. The functional principles are explained and shown graphically, technology by technology. The focus is on aspects that are crucial for the influence …
