20 percent hydrogen in the German gas network for the first time

20 percent hydrogen in the German gas network for the first time

In December, theE.ON attachment Avacon will start adding hydrogen to asub-grid in Saxony-Anhalt. Step by step, up to 20 percent hydrogen will be added to natural gas in the coming heating period. The common design of Avacon and the German Technical and Scientific Association for Gas and Water (DVGW) is intended to demonstrate that it’s technically possible to feed hydrogen into an being gas network at a significantly advanced chance than preliminarily imaged in the DVGW’s specialized rules. Bias and systems don’t have to be modified for this process. The results of the design serve as a model for the unborn use of hydrogen in gas distribution networks. Laboratory tests show that numerous appliances in homes can be operated with over to 30 percent hydrogen amalgamation. As part of the blessing process, all appliances are tested with test gas that formerly contains 23 percent hydrogen. These laboratory results are to be backed up in the common design by the experience gained from their use in practice.

“Our common design is an important corner in the use of hydrogen as an essential element for a successful energy transition,”saysProf.Dr. Gerald Linke, Chairman of the Board of DVGW.”We’re demonstrating in practice that the being gas structure, as well as the maturity of operations, are fit for hydrogen and are an necessary asset to lead Germany into a hydrogen frugality and make it climate neutral.”
A network section in Avacon’s gas distribution network in the Jerichower Land region of Saxony-Anhalt was named for the design. This is particularly suitable because the network structure installed there’s representative of the entire Avacon gas distribution network and the results are thus transmittable. The network section is a medium- pressure distribution network with a channel length of about 35 kilometres, from which about 350 network guests are supplied with natural gas. With the corresponding quantum of gas appliances, which are substantially used for heat force, the named network section covers a wide range of appliance technology.

This will mark the morning of the blending phase in the coming phase of the design. The injection of hydrogen is planned over the two heating ages2021/22 and2022/23 in stages of 10, 15 and 20 percent hydrogen amalgamation. When the system is commissioned at the end of 2021, ten percent hydrogen will be added to the natural gas over a period of about four weeks in the first stage, which is still within the amalgamation position covered by the DVGW regulations. In about one third of the gas appliances, arbitrary measures of the combustion quality are carried out with measures of the factual hydrogen content on point in order to scientifically accompany the feed- heft at all feed-in stages.

Step by step, in supplements of five percent, the maximum hydrogen amalgamation is to be reached up to 20 percent. The 15 percent blending phase is planned for the first quarter of 2022. After an evaluation, the target attention of 20 percent hydrogen is to be reached at the end of the heating period. Another 20-percent amalgamation phase will follow over several weeks in the2022/23 heating period. In addition to blending as slightly as possible, unpredictable feed- sways are also planned in order to replicate the unpredictable renewable powers as hydrogen sources and to probe the goods of shifting hydrogen contents in the stock.

In addition to renewable electricity, green feasts will come necessary as a storehouse medium and energy carrier in all sectors in the coming decades. For this reason,E.ON is making the being gas structure H2-ready and wants to play a pioneering part in the hydrogen frugality of the future. With multitudinous systems,E.ON is formerly astronomically deposited-from the decentralised generation of hydrogen to the grid integration of hydrogen and the force of guests.

The German Association of Gas and Water Professionals (DVGW) promotes the gas and water sector with a focus on safety, hygiene and environmental protection. With its further than members, the DVGW develops the generally accepted rules of technology for gas and water. Climate-neutral feasts and, in particular, hydrogen as a source of energy for the future are of particular significance in the work of the DVGW. The association initiates and promotes exploration systems and trains on the entire diapason of motifs in the gas and water sector. In addition, it maintains a testing and instrument system for products, persons and companies. The specialized rules of the DVGW form the foundation for the specialized tone- administration and particular responsibility of the gas and water assiduity in Germany. They guarantee a secure gas and water force of the loftiest transnational standard. Thenon-profit association was innovated in 1859 in Frankfurt am Main. The DVGW is economically independent and politically neutral. With nine indigenous groups and 62 quarter groups, the DVGW operates on a original and supra-indigenous position and is represented throughout the Federal Republic. Motifs with a civil or European dimension are covered by the head office in Bonn with services in Berlin and Brussels.
The Avacon Group, one of Germany’s largest indigenous energy force companies, brings energy exactly where millions of people need it. Fast, dependable, effective and environmentally friendly. Avacon is a mate for indigenous energy results in the areas of electricity, gas, water, heating, cooling, mobility and lighting. Using intelligent energy networks, the company connects people from the North Sea seacoast to southern Hesse, from the Dutch border to Saxony-Anhalt. With around workers and about 270 trainees, the Avacon Group is one of the largest employers and coaches in the region and therefore a applicable profitable factor. Avacon is part of theE.ON Group, but at the same time has a strong external character. Further than 80 cosmopolises and counties hold38.5 percent of the shares in Avacon.
